After a year that saw many parts of the country hit by scorching heat, devastating wildfires, severe storms and record flooding, a new Environment Massachusetts report documents how global warming could lead to certain extreme weather events becoming even more common or more severe in the future.
In the United States, 49 million Americans receive their drinking water from surface sources located within 50 miles of an active nuclear power plant – inside the boundary the Nuclear Regulatory Commission uses to assess risk to food and water supplies.
Coal-fired power plants are the single largest source of mercury pollution in the United States. Emissions from these plants eventually make their way into Massachusetts’ waterways, contaminating fish and wildlife. Many of Massachusetts’ waterways are under advisory because of mercury contamination. Eating contaminated fish is the main source of human exposure to mercury. Mercury pollution poses enormous public health threats. Mercury exposure during critical periods of brain development can contribute to irreversible deficits in verbal skills, damage to attention and motor control, and reduced IQ. In 2011, the U.S. Environmental Protection Agency (EPA) developed and proposed the first national standards limiting mercury and other toxic air pollution from existing coaland oil-fired power plants. Implementing these standards will reduce mercury in our waterways and fish, and protect public health.
This year's findings in The National Solar Jobs Census clearly illustrate that the solar industry is a strong and growing cluster that is responsible for thousands of jobs across every state in the nation. The unprecedented growth of the industry is providing much needed job creation despite an historic economic and workforce downturn. The optimism of solar employers in the midst of these conditions suggests that job growth will continue for years to come.
All Americans should be able to breathe clean air. But pollution from power plants and vehicles puts the health of our nation’s children and families at risk. Ground-level ozone, the main component of smog, is one of the most harmful and one of the most pervasive air pollutants. According to the American Lung Association, nearly half of all Americans – 48 percent – still live in areas with unhealthy levels of smog pollution. Studies show that on days with high concentrations of smog pollution in the air, children and adults suffer more asthma attacks, increased respiratory difficulty, and reduced lung function. Exposure to smog pollution can exacerbate respiratory illness and even cause premature death. Sensitive populations including children, the elderly, and people with respiratory illness are particularly at risk of the adverse health effects of air pollution.
Though air quality has improved significantly in the last decade as a result of policies at the state and federal level, there is still much to be done, as there are millions of people living in metropolitan areas around the country exposed to multiple days each summer when the air is unhealthy to breathe. This report ranks metropolitan areas for their unhealthy air days in 2010 and 2011. This report also presents data indicating that the problem may have been even worse than we thought. Because the national health standard for smog pollution set in 2008 was set at a level that scientists agree is not protective of public health, people across the country have been exposed to days of poor air quality each summer without even knowing it. We have calculated the additional days on which the air was unhealthy to breathe, according to a pollution threshold that is more consistent with what scientists say is necessary to protect public health. But because the 2008 standard was set too loosely, the public was not alerted to these days of unhealthy air.
