I just happened to come across this while searching for something else.
The American Lung Association, Environment Defense Fund, and other groups are working to establish an emissions control area in U.S. waters to protect the health of Americans from global shipping pollution.
Some excerpts from their report Protecting American Health from Global Shipping Pollution:
Ocean-going ships impact air quality in U.S. coastal cities and ports and even send pollution hundreds of miles inland…
The large ocean-going ships that travel along U.S. coastlines and dock at our nation’s ports deliver considerable amounts of pollution in addition to the goods they bring. Much of the pollution from these large vessels is concentrated in ports and the densely populated metropolitan areas near ports that, in almost every instance, already suffer from unhealthy air.
The health effects of diesel emissions in general are well documented. Diesel air pollution adds to cancer risk all around the United States. In many places, diesel emissions create the greatest contribution to cancer risk from air pollution…
In addition, because diesel emissions are a complex mixture of chemicals, exposure to this pollution contributes to a wide range of non-cancer health risks, including pulmonary disease, cardiovascular effects, neurotoxicity, low birth weight in infants, premature births, congenital abnormalities and elevated infant mortality rates.
Particulate matter can aggravate respiratory conditions such as asthma and chronic bronchitis and has been associated with cardiac arrhythmias (heartbeat irregularities), heart attacks and premature deaths. People with diabetes, heart or lung disease, the elderly and children are at highest risk from exposure to particulate pollution…
Oxides of nitrogen transform into aerosol particulates and also combine with volatile organic compounds in the presence of sunlight to form smog, or ground-level ozone. High ozone levels cause acute respiratory problems, aggravated asthma, decreased lung function, inflammation of lung tissue, an increase in hospital admissions and emergency room visits for respiratory causes, and crop damage. Children with asthma are among those most at risk. Ozone also is associated with premature death.
Pollution from ocean-going ships impacts our environment, in addition to impacting public health. The same fine particles that can be breathed deep into the lungs adversely affecting human health also cause the haze that pollutes scenic vistas in national parks and wilderness areas and creates “brown clouds” in our urban centers.
The constituents of diesel exhaust also contribute to the acid rain that continues to harm sensitive ecosystems across the United States. Acid rain occurs when pollutants like SO2 and NOx react with water, oxygen, and other chemicals in the atmosphere to form various acidic compounds. The result is a mild solution of sulfuric acid and nitric acid.29 When this acid falls back to the earth, it harms our nation’s revered ecosystems–causing acidification of lakes and streams and con- tributing to the damage of trees, like red spruce trees, at high elevations and many sensitive forest soils.
Pollution from ocean-going vessels also contributes to global climate change. In 2006, in U.S. waters alone, these vessels emitted about 55.6 million metric tons of CO2.31 Additionally, ocean-going ships contribute about 1.7% of global black carbon emissions every year. Black carbon refers to the solar-absorbing component of soot, which is released during the combustion process, and is another potent global warming pollutant. Studies show that black carbon triggers snow and ice melting, and contributes to Arctic warming. And in some places, including the Alaska region, shipping can contribute an additional 40% to atmospheric con- centrations of black carbon. Further, black carbon from shipping could have disproportionate effects on air quality near port areas because of the intensity of shipping in these areas.
On the new Debra’s List I now have an icon for products Made in the USA. By choosing these products you reduce the market for globally shipped products.
