California’s Air Pollution Causes Asthma, Allergies and Premature Births

More than half of America’s dirtiest cities are in California, and rates of illness there are rising. Is it too late to reverse the trend?

Martha Cota awakened one morning to find her infant son, Jose Miguel, gasping for air, his lips and the skin under his fingernails blue from lack of oxygen. Terrified, she rushed him to her local hospital in Long Beach, Calif., where doctors stabilized the toddler and sent him home with medications to control his fever and an inhaler to help him catch his breath. The cycle went on for more than five years — Jose turning blue and barely able to breathe, Cota frantically strapping him into his car seat and racing through traffic, spending countless days and nights sitting in hospital emergency rooms.

Like so many other kids in their working-class neighborhood not far from Long Beach’s massive port, Jose had severe asthma, and it took doctors years to hit on a regimen that controlled his symptoms. “He could have died at any time,” Cota told me, her eyes brimming with tears, when we conversed one April morning through an interpreter at a coffee shop near her office in Long Beach. “At least once a month, I’d get a call from his school threatening to send me to jail because he was absent so much.”

Tall and attired in an elegant black suit, Cota, who is now in her late 40s, has a long mane of dark hair shot through with auburn highlights and large, expressive eyes. She was a social worker in her native Mexico and now works as a community educator for the Long Beach Alliance for Children with Asthma. When she first discovered that many other women and children in her community were having trouble with respiratory illnesses, she was determined to find out why living downwind of the nation’s largest port complex was making so many people sick.

Even at noon on this otherwise sunny day, the sky was blanketed in hazy toxic smog from the ports of Los Angeles and Long Beach, the entry points for more than half of the goods shipped into the United States and the largest source of air pollution in California.

Every day, idling cargo ships carrying 30,000 containers from Asia and the Pacific basin are unloaded by construction cranes towering more than 200 feet high on the docks. Then the containers are dispatched from the rail yards alongside the harbor onto 1,200 diesel-powered freight trains that ferry goods up and down the coast, and 35,000 semi tractor-trailers that speed along heavily congested highways to the rest of the country. Since the 1970s, the massive port complex has exploded to five times its original size, transforming the surrounding area into what one local physician called “an environmental nightmare.”

California may have a reputation as a sun-kissed paradise with some of the world’s most photographed real estate — Southern California’s sparkling white beaches, the celebrated rocky coastline along Big Sur and the epic grandeur of Yosemite and the Sierras. But the reality is that the nation’s most populous state is an industrial colossus — the world’s ninth-largest economy — with the worst air quality in the nation, according to annual report cards issued by the American Lung Association.

Shippers under the gun to meet new air quality standards

In the Belgian port of Zeebrugge one spring day, a hulking cargo ship waiting to make its 36-hour run to the Swedish port of Gothenburg sat as a model for European and international efforts to reduce vessel emissions.

The German-built Schieborg Delfzijl is one of the first cargo vessels built to comply with the International Maritime Organisation (IMO) standard for nitrogen oxides (NOx), using a catalytic reduction system. The IMO standards apply for new vessels starting in 2016.

The vessel’s catalytic technology uses urea, which is produced from the synthesis of ammonia and carbon dioxide, to reduce nitrogen pollutants. NOx gases are produced from fuel combustion and contribute to ozone and acid raid.

Although the systems can remove 95% of NOx emissions, they are costly to install in older ships and is less effective at lower engine temperatures, such as when vessels are approaching ports or operating inside harbours.

“In places you want to use it you can’t,” said Onno Steenweg, superintendent of Wagenborg Shipping B.V. in the Netherlands, which operates the 13-year-old Schieborg Delfzijl.

International efforts to reduce emissions

Whether in harbours or on the open sea, the shipping industry has come under the microscope to reduce pollution and faces a 2016 deadline under the IMO’s Marpol convention to slash NOx emissions.

The treaty requires an 80% reduction in NOx emissions from 2000 levels in some coastal areas, and has also set caps on sulphur dioxide (SO2), carbon and other pollutants.

In some busy European ports, including Rotterdam and Gothenburg, shipping companies get discounted port dues for using catalytic systems, scrubbers and cleaner-burning engines. At Zeebrugge, the Schieborg Delfzijl and other vessels use dockside electricity connections to cut the need to run fuel-fired generators while loading and unloading.

The European Union has also put more attention on reduce marine pollution after years of efforts to control emissions from industries, power plants and road transport. Ships have traditionally been big polluters because they use heavier, less refined fuels that are cheaper to burn but more caustic for the air.

EU environment ministers agreed in October 2012 to cut the maximum sulphur content of shipping fuels by 90% to 0.1% in restricted Sulphur Emission Control Areas, which include some of Europe’s busiest waters. The rules take effect in 2015.

Outside the controlled areas, the IMO limit of 0.5% will be mandatory in EU waters by 2020. That compares with the current 3.5% for cargo vessels and 1.5% for passenger ships.

SO2, emitted when sulphur-containing fuels are burned, is a principle cause of acid rain.

Under the new EU legislation, shipping companies that use exhaust-gas cleaning systems, or “scrubbers”, will be able to use fuels with higher sulphur content as long as SO2 emissions stay under the agreed limit.

‘Only a third’ of traffic pollution caused by exhaust

Study suggests majority of particulate matter PM10 emissions come sources such as brake and road surface wear

Vehicle exhausts are responsible for only a third of traffic pollution, according to research led by the University of Hertfordshire.

The study, published in the journal Atmospheric Environment, says nearly half of the air pollution from road traffic is down to non-exhaust sources such as brake-wear, road surface-wear, and particles launched into the air from the road by passing vehicles.

As a result, Professor Ranjeet Sokhi of the University of Hertfordshire, who led the study, is calling for greater control of non-exhaust pollution.

He said: “In terms of mass, non-exhaust sources can be more important than exhaust fumes, but legislative control has focussed on exhaust emissions.

“As exhaust regulations become stricter, non-exhaust sources become proportionately more important. Continuing to control exhaust emissions alone may not be enough to achieve legal air-quality standards.”

Plans to tackle Crieff’s air pollution

One of Scotland’s most popular visitor destinations has been identified as the nation’s latest air pollution hotspot.

Crieff is different from any other small town in Perth and Kinross in that it has a trunk road running right through its centre.

For years, as a consequence of the presence of the A85, the community has suffered from traffic jams, poor air quality and difficulty in parking.

The town boasts vibrant cafés and restaurants, independent retailers, visitor attractions and a flourishing housing market, despite the national malaise.

The traffic issues, coupled with the deterioration of prominent central buildings, has, however, blighted the heart of the town and left campaigners calling for a bypass.

Their demands have now been given new weight by the findings of a Perth and Kinross Council study that reveals the extent to which traffic poses a threat to the health of Crieff.

Air quality monitoring has been carried out in the High Street for a number of years by the concerned local authority.

It is only recently, however, that an assessment of the amount of nitrogen dioxide and particulates in the air has shown a rise above acceptable levels. Extensive exposure to the emissions can be harmful to people with breathing or heart conditions and can cause respiratory problems.

As a result, the council is to move to declare the centre of Crieff an Air Quality Management Area (AQMA) and it will then move forward with a further air quality assessment and an action plan.

They will set out a raft of measures aimed at improving the area’s air quality.

Perth and Kinross already has the dubious distinction of laying claim to several of the country’s worst air pollution zones.

The centre of Perth has been designated an AQMA since 2006, with the worst affected areas including traffic bottlenecks such as the junction of Atholl Street/Melville Street/North Methven Street, and at Bridgend.

Figures released by Friends of the Earth last year identified Atholl Street as the sixth most polluted street in Scotland.

Los Angeles air pollution drops after tailpipe laws

Los Angeles air pollution – and its infamous eye sting – have declined due to California’s strict vehicle emission controls, scientists have said.

Despite a three-fold rise in the number of vehicles on southern California roads since 1960, air pollution there has decreased, a study found.

That includes peroxyacetyl nitrate, known to irritate the eyes, the US government study found.

The study “confirms” vehicle regulations worked, its author said.

“LA’s air has lost a lot of its ‘sting,'” said lead author Ilana Pollack of the National Oceanic and Atmospheric Association’s research centre at the University of Colorado Boulder.

She said the study “confirms that California’s policies to control emissions have worked as intended”.

In addition, ozone pollution has improved, although Los Angeles remains the worst city in America for ozone pollution, according to the American Lung Association.

Economic development has affected air quality in Indian cities

India’s economic development has led to worsening of air quality in major Indian cities, according to a new study published here today.

The survey was carried out by The Energy and Resources Institute (TERI) in six major cities Bangalore, Chennai, Delhi, Hyderabad, Kolkata and Mumbai.

The transport sector was ranked the highest followed by factories in and around the city as the second highest contributor towards air pollution in Chennai, Delhi, Kolkata, and Mumbai.

While respondents from Bangalore rated factories as the highest contributor of air pollution followed by transport, those in Hyderabad rated construction activities in the city as the worst offender followed by the transport sector.

The ‘TERI Environmental Survey 2013’ was conducted with a sample size of 4,039 respondents. Six themes were selected for the study — overall environment, air quality, water quality, forest/green cover, climate change, and waste and waste management.

“Air quality for the respondents in the six cities over time has either become worse or has seen no change. In terms of drinking water quality and availability, there is a perception that it has improved in all cities barring Hyderabad, where the respondents felt it has worsened,” the survey says.

British survey exposes ignorance of air quality challenge

When a London anti-pollution organisation polled British lawmakers about the greatest risks to public health, most MPs were wrong, ranking traffic accidents or heavy drinking ahead of air pollution as a leading killer of Britons.

“The vast majority of over 100 members of Parliament responding to our survey displayed a shocking level of ignorance about the health impact of air pollution,” said Simon Birkett, head of Clean Air in London, an advocacy group.

“In particular, over two-thirds of Conservative MPs responding said air pollution has less impact than road traffic accidents,” he said on releasing the survey results on 23 May.

Figures crunched by the London-based group show that the cocktail of fine particle emissions comprising gases such as nitrogen oxide (NOx) and sulphur dioxide (SO2) kill some 29,000 people in the United Kingdom each year, while 1,901 people died in traffic crashes in 2011. Only smoking kills more Britons than bad air, government health figures show, an average of 80,000 per year, with as many as 22,000 people dying of alcohol-related causes.

Dirty air across Europe

Environmental and health groups say London if by no means an isolated case. Some of the EU’s deadliest air can be found in Bulgaria and Romania, yet few urban areas escape unhealthy pollutants, according to the European Environment Agency (EEA).

Residents of most large cities in the European Union are exposed to stubbornly high levels of noxious pollutants that in some cases exceed international health standards, including fine particulates produced from emissions of NOx, SO2, ammonia (NH3) and organic compounds.

Transport, along with energy production and agriculture, are leading polluters, EEA figures show. Diesel engines, though they produce lower levels of carbon emissions, produce high NOx emissions that contribute to unhealthy ground-level ozone and smog – although newer vehicles are required to be outfitted with filtering technology.

Britain, like most EU countries, has a spotty record at enforcing the European Commission’s 2008 Air Quality Directive and other laws that are intended to reduce pollutants. The European Commission has taken action against some 20 countries – including the UK – for failing to improve air quality.

But health and environmental groups argue that the Air Quality Directive, the EU’s main pollution-fighting law, needs more teeth to punish states for inaction.
