China’s air pollution blamed for eight-year-old’s lung cancer

An eight-year-old girl has reportedly been diagnosed as China’s youngest victim of lung cancer, reigniting debate over the devastating human toll of the country’s pollution crisis.

The girl, who was not named, lived near a busy road in the eastern province of Jiangsu and doctors blamed exposure to air pollution for her condition, state media reported.

Jie Fengdong, a doctor at Nanjing’s Jiangsu Cancer Hospital, was quoted by the state-run China News Service as saying the likely cause was exposure to tiny airborne particles from vehicle emissions.

Kan Haidong, a professor from the School of Public Health at Shanghai’s Fudan University, said it was “very, very rare” for such a young child to be diagnosed with lung cancer and urged caution in making a direct link to pollution.

Children were more vulnerable to air pollution than adults, but 40 per cent of lung cancer cases were still caused by smoking, Dr Kan added.

Still, the revelation sparked renewed discussion about how to clear China’s smog-choked skies and came as Xie Zhenhua, the country’s top climate change negotiator, admitted that air pollution had “severely affected the mental and physical health of the Chinese people”.

Speaking in Beijing, Mr Xie blamed the crisis on China’s “obsolete development model” and excessive use of fossil fuels, adding: “We face daunting difficulties and challenges ahead.”

The coming weeks are likely to see thick smog envelope cities across China as winter approaches and coal-fuelled power stations start to come online.

Already the problems are being felt. In late October, toxic smog brought Harbin, a city of more than 11 million people in northeastern China, to a virtual standstill – closing schools and roads and grounding aircraft.

In June, China’s official news agency Xinhua said six people were now being diagnosed with cancer every minute, with around two million deaths each year.

“In 2020, there will be 4 million new cases of cancer in China every year,” Chen Wanqing, the vice director of China’s National Cancer Prevention and Control Research Office, told the agency.

On Tuesday, Jiangsu province’s Modern Express newspaper reported that, “the exact cause [of the girl\’s cancer] has not been determined.”

But Li Tian, a doctor from the Nanjing Chest Hospital, said cancer rates were rising and that patients were getting younger, with the highest growth group being those aged between 20 and 40.

Wang Zhaoxia, another Nanjing doctor whose hospital treated over 600 lung cancer patients in 2012, said smoking and passive smoking remained the main culprits but said air pollution was also a factor.

Chinese smog was now becoming a “threat to national security” as well as public health, Hong Kong’s South China Morning Post reported on Tuesday.

Beijing was increasingly concerned at how smog was blinding its fast-growing network of surveillance cameras, the newspaper claimed.

“Some fear terrorists may choose a smoggy day to launch attacks.”

Two special research teams – one military, one civilian – had been set up to find a solution, it added.

Zimbabwe’s battered old cars worsening air pollution

It is a common sight in Zimbabwe’s rural areas – dilapidated old cars making their way from one district to the next overloaded with chickens, maize, luggage and passengers. But environmentalists here say the aged cars are contributing to air pollution.

Tazviona Matutu, 76, from Zimbabwe’s Mwenezi district in Masvingo Province, has been a passenger in these cars and he is grateful that the operators of these old and sometimes unroadworthy vehicles are willing to accept something other than cash for his fare.

“There are no buses here to ferry people from one point to another. These aged vehicles are [helping us] as we often pay our fare in hens and maize, as most of us are very poor,” Matutu told IPS.

Air pollution worsening

But the use of these battered, old and noisy cars, which emit heavy exhaust fumes, has come at a high cost and is reportedly worsening air pollution in this southern African nation.

According to environmental lobby group Save the Environment Association, and independent environmentalist Gibson Mamutse, the continued use of these old cars could lead to disaster.

“[As of] August this year, pollution related to old cars used as public transport in villages has seriously worsened nationwide, which is really a disaster growing out of control,” Sifelumusa Mbihwa, director of Save the Environment Association, told IPS.

“In 2012, 23.3 percent of the country’s rural population complained of pollution resulting from old cars, while in August this year about 32. 4 percent complained [about pollution from old cars],” she explained.

Providing a service

In January, the Traffic Safety Council of Zimbabwe noted that 21,122 old vehicles were licenced in Zimbabwe’s rural areas and were being used as transport on rural routes traditionally shunned by legitimate public transport providers.

But Mbihwa said that the number of aged vehicles operating across the country was much higher.

“In our 2012 survey of rural car ownership in Zimbabwe … out of approximately seven million people in the countryside, three out of every 15 people own a working or dysfunctional aged vehicle through inheritance,” she said.

No paperwork

Zimbabwe National Traffic Police spokesperson Tigere Chigome said that most of the cars were unregistered and pointed out that it was difficult to police their use.

“We know there are unroadworthy vehicles operating in different places countrywide, but most of these aged cars are not registered nor licensed to carry passengers and really they have ultimately no paperwork legitimising their operations.

Independent environmentalist Mamutse told IPS that the old vehicles were “worsening air pollution, threatening our environment in both cities and villages now.”

Zim’s CO2 spew

“Mwenezi’s case of [using old cars for transport] is merely an epitome of a larger problem in the country. Zimbabwe must brace to witness the worst consequences of these old cars in the countryside.

He said that according to his own ongoing research titled “Digging out the causes for Zimbabwe’s incessant droughts”, 65 to 70 percent of the total rural emissions were from veld fires, mining, agricultural and domestic activities, with emissions from old cars contributing 30 percent to this figure.

According to Clean Air Asia, an air quality network for Asia, over nine million tonnes of carbon dioxide was emitted in Zimbabwe in 2008 through industrial activity, vehicular and energy generation. Figures from the U.S. Energy Information Administration show that also during 2008 neighbouring Zambia, which has a population of 14 million, compared to Zimbabwe’s 13.7 million people, emitted 2.2 million tonnes of carbon dioxide.

Some of the cars used to provide transport in rural areas are more than 40 years old.

“The Peugeot 404 that I’m using to ferry passengers was used by my grandfather in the 1970s and I had to resuscitate it to earn a living, transporting passengers,” Artwell Muhomba, from Mwenezi district’s Maranda village, told IPS.

“People operating businesses here [driving old cars] are aware of the environmental consequences of their practices. But really they want to put food on their tables as most of them are not formally employed,” Arnold Nerupiri, the chairperson of the Domboshava Old Transport Association from Domboshava village, told IPS.

Diwali celebrations: Delhi’s air quality worse than last year’s

Many Delhiites felt that decibels levels on Diwali night were a shade lower than previous years, but the dense haze of near-choking pollution told a different story. Now the verdict is out. The PM 10 (coarse particles) levels this year were found to be higher compared to last year at all monitoring locations in the city, the Central Pollution Control Board said.

Levels of sulphur dioxide, associated with breathing difficulty and other respiratory ailments, were also higher, according to Delhi Pollution Control Committee data.

Interestingly, the noise levels were higher than last year in many east and north Delhi areas — Mayur Vihar, Dilshad Garden, Kamla Nagar and Pitampura — but were lowered in south and central locations such as Ansari Nagar near AIIMS , ITO and Lajpat Nagar.

Even though there isn’t much of a difference in other parameters like nitrogen dioxide (NO2), PM 2.5 and carbon monoxide (CO) as compared to 2012, the peaking levels of these pollutants were extremely high on Sunday evening.

Weather conditions also played a part. The average wind speed (0.36m/sec) was lower compared to last year (0.43 m/sec) which meant that pollutants like PM 10 hung in the air instead of dispersing.

A lower mixing height (atmospheric zone of almost stable temperature and specific humidity) than last year also aggravated the condition by keeping pollutants trapped.

According to CPCB, PM 10 levels increased quite a bit from 2012, the maximum level rising by about 187 microgram per cubic metre. NO2 levels decreased at most locations while SO2 decreased at five locations but increased at two — Pitampura and Shahzadabagh . But DPCC, which monitors other locations in the city, found that SO2 levels were higher compared to 2012 — the maximum level increasing by about 26 micrograms per cubic metre.

“It’s a cause for concern. SO2 is an extremely harmful pollutant. On normal days, SO2 in Delhi is usually much below the standard. The fact that it has increased so much on Diwali points to the kind of crackers that are being manufactured ,” said Anumita Roychowdhury , executive director , research and advocacy, Centre for Science and Environment (CSE).

In fact, there could be a worrying trend hidden in the sudden peaks of certain pollutants measured real-time by DPCC. For instance, SO2 levels went up to 345 microgram per cubic metre at 11pm in RK Puram on Sunday and to 570 microgram at IGI Airport around 12.30am. NO2 levels spiked to 464 micrograms at 11.30pm in Punjabi Bagh and the PM 2.5 level at R K Puram was recorded at a high 643 microgram . These peaks are not shown in the range given by DPCC for Diwali day.

At Anand Vihar, both PM 10 and PM 2.5 were exceedingly high. PM 10 level was 13 times the permissible limit. “The levels are high in Anand Vihar also because of heavy vehicular traffic because it’s near the border with Ghaziabad ,” said M P George from air and water lab at DPCC.

Pollution inside Cars

The interior of your car may seem like a safe haven from air pollution, but it may actually be quite the opposite. Chemicals emanating from the steering wheel, dashboard, armrests and seats mix with the airborne pollution being generated under the hood to form a witch’s brew of toxins for those riding inside.

“Research shows that vehicle interiors contain a unique cocktail of hundreds of toxic chemicals that off-gas in small, confined spaces,” says Jeff Gearhart of the Ecology Center, a Michigan-based non-profit. The extreme air temperatures inside cars on sunny days can increase the concentration of Volatile Organic Compounds VOCs and break other chemicals down into more toxic constituents. Some of the worst offenders include airborne bromine, chlorine, lead and other heavy metals. “Since these chemicals are not regulated, consumers have no way of knowing the dangers they face,” adds Gearhart.

Exhaust fumes also find their way into the passenger cabins of many cars. The International Center for Technology Assessment ICTA found that concentrations of carbon monoxide a noxious by-product of internal combustion known to cause headaches, dizziness, nausea and fatigue as well as being a major asthma trigger may be 10 times higher inside any given car than outdoors along the roadside. ICTA added that in light of the fact that the average American spends an hour and a half driving around each day, in-car air pollution may pose “one of the greatest modern threats to human health.

“To help consumers minimize their exposure, the Ecology Center released the fourth version of its Consumer Guide to Toxic Chemicals in Cars in 2012, comparing over 200 different cars across the 2010 and 2011 model years. Those scoring the most kudos in regard to interior air quality include the Honda Civic, Toyota Prius and Honda CR-Z. The Civic scored first by being free of bromine-based flame retardants BFRs in interior components, utilizing polyvinyl chloride PVC-free interior fabrics and trim, and having low levels of heavy metals.

Meanwhile, pulling up the rear were Mitsubishi’s Outlander Sport, the Chrysler 200 SC and the Kia Soul. The Outlander finished in last place due to its use of BFRS as well as antimony-based flame retardants in its interior, chromium treated leather components and excessive amounts of lead in seating materials.

“The good news is overall vehicle ratings are improving,” reports the Ecology Center, adding that the top performers have gotten rid of BFRs and PVC altogether in their interiors. “Today, 17 percent of new vehicles have PVC-free interiors and 60 percent are produced without BFRs.

“Consumers can check on their late model car by steering their web browser to the HealthyStuff.org website, the Ecology Center’s free online resource for consumer information. While environmental and public health groups are working to try to get automakers to clean up their interiors, individuals can reduce their exposure by parking in the shade, using interior sun reflectors to keep temperatures down inside the car and rolling down the windows to let the fresh air in.

Iran’s air pollution kills 2700 people per year

Heavy air pollution in Iran kills thousands of people in the country each year.

Head of the Healthcare and Medical Education Ministry’s environment protection center Kazem Nadafi said that about 2700 people in Iran die each year because of heavy air pollution, ISNA reported.

Nadafi said that 2522 patients with cardiovascular diseases and 4525 people with respiratory diseases caused by air pollution are in hospitals now.

Referring to 70,000 old cars used in the country, he said that the amount of pollution they create equals the pollution caused by 2.1 million normal cars.

“If we could stop the use of old cars, the air pollution level would decrease by 30 percent.” Nadafi said.

He also called for the creation of online payments which would allow Iranians to pay for certain items and services online, omitting the need to go there by car and thus reducing the air pollution.

“If 40 percent of Iranians use such services, the air pollution in Tehran would drop by 12 percent,” Nadafi said.

The air over Iran’s capital is amongst the most polluted in the world, and experts say many Iranians suffer serious health problems as a result.

According to PSI Pollutant Standards Index, last year Iran had 147 days during which the air quality was substandard. Two years ago this number stood at 217 days.

The problem of Tehran’s air pollution has repeatedly forced the government to declare some days as holiday in the capital due to the high degree of pollution.

Tehran’s governor Seyyed Hossein Hashemi said earlier that the air pollution and the use of old cars are Tehran’s two main challenges and they need to be addressed as soon as possible.

Tehran’s pollution is mainly caused by the bumper-to-bumper traffic in a city wedged between two mountains that trap the fumes.

Motor vehicles account for 70 percent of pollution in the Iranian capital. Some experts and officials say the low quality of the gasoline and diesel fuels that are used is responsible for the heavy smog in Tehran.

Officials say all automakers should be committed to manufacturing vehicles that meet Euro-4 and Euro-5 standards.

Iran currently produces 14 million liters of Euro-4 and Euro-5 gasoline per day. The amount will reach 22 million once the RFCC unit of Shazand oil refinery comes on stream.Major Iranian cities also struggle with air pollution on a seasonal basis.

The fact that some other big cities like Isfahan, Mashhad, Arak, Karaj, Qom, Tabriz, and Ahvaz are facing a somewhat similar situation backs up this view.

Iran had previously implemented some regulations for tackling the problem of air pollution, but none of them worked.

Air pollution forecast for up to three days at 10 locations in Mumbai on anvil

In a few months, you will know exactly when to keep the pollution masks or inhalers handy. A system being put in place in the city will forecast air quality for up to three days.

Screens at 15 major city junctions will also display real-time weather information and air pollution levels. The Indian Institute of Tropical Meteorology (IITM) has joined hands with the Indian Meteorological Department (IMD) and the BMC to set up the System of Air Quality Forecasting and Research (SAFAR) project.

Explaining the process of air pollution forecasting, programme director Dr Gufran Beig said they would rely on a numerical model. “Data would be transferred from 10 different locations to the IMD control room. Using this data, figures for the pollution level would be calculated and displayed on boards across the city” he said. The forecast will be based on the past few days’ pollution levels, expected weather conditions and other factors like vehicular load and fuel emission at that location.

By mid-2014, 10 air quality monitoring stations will be established and sensors set up. The IITM and BMC have zeroed in on Worli Dairy, Mulund, Malad, Borivli National Park, Colaba’s IMD office, Santa Cruz, Bhandup, Chembur, Turbhe and Panvel.

For air quality prediction, 200 college students have volunteered to gauge vehicular load at chosen traffic junctions. “From November, the students, as part of their projects, will spend one hour per week at a traffic junction and note down the type of vehicles passing. This is a random statistical method that will give us an idea of the pollution load at each hour of weekday and weekends,” said Beig.

He added: “SAFAR aims at understanding the immediate health hazards from pollution and knowing the current level of air quality and its future projections. This will help take suitable systematic measures to avoid health problems.”

Pollutants such as oxides of nitrogen, carbon monoxide, suspended particulate matter, black carbon and benzene can lead to health problems such as respiratory problems, hospitalization for heart and lung diseases, and even premature death.

The sensors at each of the 10 air quality stations will be location-specific. “For instance, if a particular area has more complaints of acid rain, the station will measure ammonia levels,” said K S Hosalikar, deputy director general of IMD, Mumbai.

“We will make sure the sensors are neither too close nor too far from a pollution source, like a factory. This will help us get an unbiased measurement of pollution.”

Real-time weather information and pollution levels will soon be available at big traffic intersections in the city. By mid-2014, the city will get air quality monitoring systems at ten locations, data from which will be displayed on big screens at 15 of the city’s busiest crossings.

Indian Institute of Tropical Meteorology (IITM) along with Indian Meteorological Department (IMD) and the BMC will be setting up the project System of Air Quality Forecasting and Research (SAFAR). Explaining the process of air pollution forecasting, programme director Dr Gufran Beig said a numerical model would be relied upon.

“Data would be transferred from 10 different locations to the IMD control room. Using this data, figures for the pollution level would be calculated. These numbers would be displayed on boards placed across the city. It will also forecast air pollution levels for three days at various key locations,” he said.

For the air quality prediction, 200 college students will volunteer to gauge vehicular load at traffic junctions. “From November onwards, college students as part of their projects will spend one hour per week on a pre decided traffic junction and note down what kind of vehicles pass. This is a random statistical method, which will give us an idea of the pollution load at each hour of weekday and weekends,” said Beig.

The IITM along with the BMC have finalized the ten locations, which include areas such as Worli Dairy, Mulund, Malad, Borivali National Park, Colaba’s IMD office, Santa Cruz, Bhandup, Chembur, Turbhe and Panvel.

“The programme aims at understanding the immediate health hazards due to pollution and knowing the current level of air quality and its future projections well in advance. This would help take suitable systematic measures to avoid the health hazards,” Beig told TOI.

Beig said pollutants, such as oxides of nitrogen, carbon monoxide, suspended particulate matter, black carbon and benzene, were a cause for serious concern. Exposure to these pollutants, he added, leads to problems such as increased respiratory symptoms, hospitalisation for heart and lung diseases, and even premature death.

The sensors at every station will be location-specific. “For instance, if a particular area has more complaints of acid rain, the station will measure ammonia levels,” said K S Hosalikar, deputy director general of IMD, Mumbai. “We will make sure that the sensors are neither too close nor too far from a pollution source like a factory. This will help us to get an unbiased measurement of pollution.”

Stressed pregnant women exposed to pollution affects child behavior

The combination of maternal physical and psychological stress during fetal development magnifies the effect of each exposure, U.S. and Polish researchers say.

Lead author Frederica Perera, director of the Columbia Center for Childre’s Environmental Health at the Mailman School of Public Health, reported maternal demoralization — a measure of psychological distress capable of affecting a mother’s ability to cope with stressful situations — was greatest among children with higher levels of prenatal exposure to polycyclic aromatic hydrocarbons in air pollution.

Polycyclic aromatic hydrocarbons are air pollutants generated by combustion sources such as motor vehicles, coal-fired power plants, residential heating and tobacco smoke. In Krakow, Poland, where the study took place, as in many areas worldwide, coal burning is a significant air pollution source.

Although Krakow has relatively high ambient concentrations of polycyclic aromatic hydrocarbons from coal-burning and vehicle emissions, levels are within the range seen in many other urban areas worldwide.

“Air pollution exposure is ubiquitous and often co-occurs with socioeconomic disadvantage and maternal psychological distress,” Perera says in a statement.

“The findings are of concern because attention problems and anxiety and depression have been shown to affect peer relationships, academic performance and future well- being of children.”

Perera, Dr. Wieslaw Jedrychowski of the University of Krakow and colleagues tracked 248 mother-child pairs from pregnancy through age 9. Personal air sampling was completed during pregnancy to estimate prenatal PAH exposure. Behavioral problems were assessed using the Child Behavioral Checklist, a set of questions to which mothers responded about their child’s behavior.

Maternal demoralization was correlated with socioeconomic factors such as material hardship. Levels of maternal demoralization were ascertained by a questionnaire during the second trimester.

The study, published online in the journal Pediatrics, found maternal demoralization was linked with a number of behavioral problems in children including anxiety, depression, attention problems, rule-breaking, externalizing problems and aggressive behavior.
