Air pollution exposure can be measured for a person, a group, such as a neighborhood or a country's children, or an entire population. For example, one would want to determine a geographic area's exposure to a dangerous air pollution, taking into account the various microenvironments and age groups.
The tiny pollutants emitted by fossil fuel combustion and wildfires may be raising the risk of adverse birth outcomes, a study has found. Exposure to fine particulate matter (PM 2.5) can cause ...
In contrast, children from the low pollution area scored as expected on IQ tests and showed no significant sign of the risk of brain lesions. Concerning traffic-related air pollution, children of mothers exposed to higher levels during the first trimester of pregnancy were at increased risk of allergic sensitization at one year age.
While the effects of air pollution on the respiratory diseases are well understood, air pollution also affects the cardiovascular system at the same level as or higher level than the respiratory system, [37] and the adverse cardiovascular health outcomes in both children and adults are high when exposed to air pollution. Carbon monoxide, oxides ...
The Clean Air Act requires the EPA to set US National Ambient Air Quality Standards (NAAQS) for the six CAPs. [6] The NAAQS are health based and the EPA sets two types of standards: primary and secondary. The primary standards are designed to protect the health of 'sensitive' populations such as asthmatics, children, and the elderly.
It is a health protection tool used to make decisions to reduce short-term exposure to air pollution by adjusting activity levels during increased levels of air pollution. The Air Quality Health Index also provides advice on how to improve air quality by proposing a behavioral change to reduce the environmental footprint.
Air pollution is the introduction of chemicals, particulate matter, or biological materials into the atmosphere that cause harm or discomfort to humans or other living organisms, or damage ecosystems. Health problems attributed to air pollution include premature death, cancer, organ failure, infections, behavioral changes, and other diseases.
This is in part because pollution causes so many diseases that it is often difficult to draw a straight line between cause and effect. There are many types of pollution-related diseases, including those caused by air pollution, contaminated soil, water pollution and lacking water, sanitation and hygiene (WASH). Air pollution can be reduced.
