Embodiment Construction

[0061] Below in conjunction with accompanying drawing and example, the present invention is described in further detail.

[0062] Based on the exposure time-space behavior activity pattern and the pollution mapping method, the present invention provides an individual air pollution exposure simulation measurement method that can accurately evaluate the air pollution exposure of individuals not carrying measuring instruments by using means such as geographic information system and spatial analysis.

[0063] First, the six air pollutants (SO 2 , NO 2 , CO, O 3 , PM 10 , PM 2.5 ) concentration data for fine pollution mapping (spatial resolution ≤ 200m); secondly, for individuals who do not carry mobile monitoring devices, search for nearby devices based on their mobile phone APP location (search radius is 200m); finally, simulate pollutant concentration based on individuals Data, combined with individual exposure parameter data, to calculate individual air pollution simulated ...

Abstract

The invention discloses an individual air pollution exposure simulation measurement method based on position matching. The method comprises the following steps: firstly, carrying out pollution fine drawing by utilizing six air pollutant concentration data acquired by a pollution monitoring station and individual mobile monitoring equipment; secondly, for individuals without mobile monitoring equipment, searching for adjacent equipment based on mobile phone APP positioning of the individuals; and finally, based on the individual simulated pollutant concentration data, calculating the individualair pollution simulated exposure dose in combination with the individual exposure parameter data. Aiming at the situation that the current air pollution exposure measurement work mainly surrounds a large range of people and carries mobile monitoring equipment individuals, the invention provides an individual air pollution exposure simulation measurement method aiming that mobile monitoring equipment is not carried. The method is high in comprehensiveness and high in referenceability, and references are provided for individuals to take correct air pollution exposure protection measures.

Description

technical field [0001] The invention relates to the field of environmental exposure assessment, in particular to an individual air pollution exposure simulation measurement method based on position matching, which uses a pollution mapping method and an exposure behavior activity pattern to simulate the air pollution exposure of individuals not carrying portable measuring instruments. Background technique [0002] With the rapid development of my country's social economy and the rapid advancement of urbanization and industrialization, air pollution problems represented by fine particulate matter and ozone have become increasingly prominent, and frequent incidents of excessive air pollution concentrations have seriously affected public life and health. As of 2018, 64.2% of the 338 cities across the country still have urban ambient air pollution exceeding the standard, and the average proportion of days exceeding the standard is 20.7%. Air pollution with excessive concentration...
