Significantly, AQI values reflect air quality management objectives, which are based on the lowest achievable emissions rate, rather than exclusive concern for human health. The Air Quality Health Index (AQHI) is a scale designed to help understand the impact of air quality on health. It is a health protection tool used to make decisions to ...
Environmental factors such as air and water quality, patterns of energy use, and patterns of land use can directly and indirectly affect health of citizens. [34] WHO's findings found that 24% of global disease and 23% of deaths are caused by environmental factors (although they vary from developing countries with 25%, and developed with 17%). [34]
