67% of the nation's sulfur dioxide (SO2), which causes acid rain, comes from electricity generation. According to the American Lung Association, sulfur dioxide affects breathing, increases respiratory illness, weakens pulmonary defenses and aggravates cardiovascular diseases.
28% of nitrogen oxides (NOx), which react with sunlight to create ground level ozone and smog, come from electricity generation. Ozone and smog irritate the lungs and lower resistance to infections like influenza, according to the American Lung Association. |
Particulate matter is a type of air pollution more commonly referred to as soot. Exposure to particulate matter is especially harmful to people with lung disease (e.g. asthma, bronchitis, emphysema) and heart disease.
Carbon dioxide (CO2) is a climate change gas that causes global warming. Global warming can lead to the spread of infectious diseases such as malaria and dengue fever. It also contributes to air quality problems, which increase the health effects of other air pollutants. Long-term effects associated with fossil fuel burning could be even more alarming than air pollution-related deaths today. In the future, tropical diseases could thrive as the earth's climate warms, and deaths due to extreme weather conditions (e.g. hypothermia) could increase.
Nuclear energy poses the unique threats of radioactive waste and radiation. Waste from nuclear energy facilities is dangerous to transport and to dispose of. In addition, there is potential for a disastrous nuclear accident, like Chernobyl or Three Mile Island. Health effects of radioactive waste include cancer, sterility and even death. Radiation may cause immune system damage, leukemia, miscarriages, stillbirths, deformities and genetic mutations.
Mercury is a highly toxic metal that is released from coal-fired power plants. Mercury accumulates in the fat cells of fish and other animals. When humans eat the fish, they are exposed to mercury. Mercury causes permanent damage to the liver and central nervous system, causing loss of motor function, slurred speech, tunnel vision, and loss of hearing. Mercury is particularly harmful when ingested by pregnant or nursing women as it can cause birth defects and developmental defects. Because mercury accumulates in biological organisms it is constantly being recycled in the environment as it moves up the food chain. Click here for a 2-page report on Mercury in Massachusetts.
