It consists of three categories: health impacts, air quality, and water and sanitation. The health impacts category includes the environmental risk exposure indicator. Environmental health is the branch of public health concerned with all aspects of the natural and built environment affecting human health.
A strategic objective of the policy was to assess health effects of environmental risks by conducting health impact assessments. [32] The government also plans to increase countries abilities to deal with environmental emergencies including climate change, air pollution, and radiation that could be harmful to health. [32]
Air pollution can occur naturally or be caused by human activities. [4] Air pollution causes around 7 or 8 million deaths each year. [5] [6] It is a significant risk factor for a number of pollution-related diseases, including heart disease, stroke, chronic obstructive pulmonary disease (COPD), asthma and lung cancer.
The Six Cities study was born in the wake of the 1970s energy crisis amid growing concerns that a squeeze on oil supply would lead to greater use of low-quality coal and, therefore, higher mortality from air pollution. [8] The harmful health effects of burning coal had already come to light following the 1952 Great London Smog (in the United ...
These impacts can be split into operational impacts (fuel sourcing, global atmospheric and localized pollution) and construction impacts (manufacturing, installation, decommissioning, and disposal). All forms of electricity generation have some form of environmental impact, [ 211 ] but coal-fired power is the dirtiest.
Looking down from the Hollywood Hills, with Griffith Observatory on the hill in the foreground, air pollution is visible in downtown Los Angeles on a late afternoon.. 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.
Climate change is altering the geographic range and seasonality of some insects that can carry diseases, for example Aedes aegypti, the mosquito that is the vector for dengue transmission. Global climate change has increased the occurrence of some infectious diseases. Infectious diseases whose transmission is impacted by climate change include, for example, vector-borne diseases like dengue ...
Air quality laws are often designed specifically to protect human health by limiting or eliminating airborne pollutant concentrations. Other initiatives are designed to address broader ecological problems, such as limitations on chemicals that affect the ozone layer , and emissions trading programs to address acid rain or climate change .
