Embodiment 1

[0040] Example 1: During November 2016 to January 2017, Muye District of Xinxiang City was selected to select the same area as a sampling area, and two days were selected to monitor the air pollution in this area, and the air pollution index was recorded. The monitoring result was air pollution. The quality index AQI values ​​are 70 and 350 respectively, which are mild haze and severe haze weather respectively. Sampling for light haze weather is 48 hours and severe haze weather is sampling for 36 hours. Atmospheric particles are collected by Anderson impact eight-stage sampler sample;

[0041] At the same time as the collection of atmospheric particulate matter samples, 20 volunteers were recruited in this area to collect epidermis swab samples. Among the 20 volunteers, there were 10 males, including 5 children; 10 females, including children. 5 people; in order to reduce the influence of sampling site factors, the forehead of the volunteers was uniformly selected as the wipin...

Abstract

The invention relates to the technical field of exposure assessment methods, in particular to a method for multipath exposure assessment of a human body to a flame retardant based on the combination of atmospheric stratified sampling and skin wiping. According to the method, the monitoring is performed according to the air condition of the field, and the air particle and the dermal exposure are simultaneously sampled, wherein the air particles are collected by a graded sampler, the samples can be collected in different diameters, the exposure characteristics of the particles with different diameters can be accurately assessed, the simultaneous detection is performed, the simultaneous assessment of the multi-path exposure is realized and the exposure characteristics of the human body to thepollutants can be comprehensively understood.

Description

Technical field: [0001] The invention belongs to the technical field of flame retardant exposure assessment methods, and in particular relates to a multi-path exposure assessment method of a human body to flame retardants based on the combined use of atmospheric graded sampling and skin wiping. Background technique: [0002] With the continuous development of science and technology, the environmental pollution caused by industrialization and urbanization has aroused widespread concern. Among them, air pollution has gradually become one of the more serious environmental pollution problems in our country. In recent years, the frequent occurrence of air pollution with a wide range and long duration in our country has attracted widespread attention; The impact of persistent organic pollutants on the particulate matter on the environment and human health is a research hotspot. Particle size is a key parameter affecting the properties of atmospheric particulate matter. The physica...
