Public air pollution exposure risk measure index calculating method

Abstract

The invention discloses a public air pollution exposure risk measure index calculating method comprising the following steps: firstly building an air pollution exposure risk subindex grade-corresponding pollutant item exposure dosage limit value look-up table; secondarily, calculating an individual real time air pollution exposure dosage according to an individual real time activity place pollutant concentration, an individual body weight, and activity time period and a breathing rate in the activity time period, and calculating each pollutant item exposure risk subindex according to an exposure risk subindex calculating method; finally, selecting the maximum exposure risk subindex of each pollutant item as the individual received air pollution exposure risk in the time scope. Existing airquality indexes cannot reflect the individual air pollution exposure level, and a single exposure dosage cannot integrally evaluate the exposure risks; the method can solve said problems, and provides the public air pollution exposure risk measure index with a high integrity and strong reference, thus providing reference suggestions for the public so as to effectively avoid air pollution expose risks.

Description

technical field [0001] The invention relates to the field of environmental health risk assessment, in particular to a method for calculating public air pollution exposure risk measurement indices. Background technique [0002] As the world's largest environmental health risk, air pollution affects human life all the time. For China in the context of rapid urbanization, the pollution situation is even more severe. According to the World Health Organization, the number of deaths due to air pollution in China is 1.0328 million every year, and the annual loss of life due to it is 23.05 million years, ranking first in the world, 27 times and 29 times that of the United States respectively. At the same time, the World Burden of Disease pointed out that air pollution is the seventh leading cause of death in the world, while it has climbed to the fourth in China. [0003] In 1996, the country promulgated the "Air Quality Standard" (GB3095-1996) and proposed the Air Pollution Index...

Problems solved by technology

However, although both API and AQI have proposed a single conceptual index to normalize the expression of the impact of various pollutants on human health, the health effects of air pollution on the human body are determined by the environmental concentration of air pollution and individual exposure. The comprehensive reflection of air pollution levels, the API or AQI index that does not consider individual exposure conditions cannot reveal the differential impact of air pollution on different individuals, let alone meet the relevant requirements of health risk management

[0004] In 2017, the Ministry of Environmental Protection issued the "Technical Guidelines for Assessment of Exposure to Environmental Pollutants" (HJ875-2017), an important step in the transformation from environmental management to environmental health risk management, and incorporated the principle of spatio-temporal consistency as the primary assessment principle In the guidelines, but the guidelines only made clear requirements on the estimation of the average daily exposure of a single pollutant, and failed to propose a normalized index that takes into account multiple pollutants to quantify their health risks
