Method for evaluating odor pollutants in working environment

Abstract

The invention relates to a method for evaluating odor pollutants in a working environment. The method comprises determining an odor pollution source, recognizing the main odor pollutant, and analyzing the characteristics, distribution and so on of the odor pollutant; constructing a mathematical model describing the relationship between the odor pollutant concentration and the aversion degree; monitoring the odor pollutant concentration in the environment by field sampling to evaluate the field odor pollution; simulating the odor pollutant concentration by hydromechanical calculation software FLUENT to obtain the concentration of each odor pollutant in the region; and representing the field odor degree by the odor aversion degree. With reference to the health risk analysis four-stage method, aiming at the condition of odor pollutants in the working environment, the invention derives a mixture aversion degree calculation formula by fitting the aversion degrees of methanthiol and ethanethiol according to a single odorant aversion degree evaluation technique introduced from abroad in combination with related data.

Description

technical field [0001] The invention belongs to the field of preventive medicine occupational health and occupational disease control technology and petrochemical occupational health risk management science and technology, and especially proposes an evaluation method for the degree of odor pollution in the evaluation of occupational disease hazards of construction projects, which is mainly used in Occupational disease hazard assessment characterized by odor pollution such as sewage treatment. Background technique [0002] Petroleum refining enterprises, waste incineration landfills, sewage treatment plants, etc. will produce a large amount of toxic and harmful substances, such as sulfur dioxide, hydrogen sulfide, mercaptans, sulfides, hydrocarbons, amines, etc. Most of these substances are foul-smelling substances, and the smell threshold is extremely low. Generally, a slight release will make workers feel bored, thereby affecting people's health. [0003] At present, in th...

AI Technical Summary

Problems solved by technology

Most of these substances are foul-smelling substances, and the smell threshold is extremely low. Generally, a slight release will make workers feel bored, thus affecting people's health.

[0003] At present, in the domestic environmental impact assessment, the index of odor intensity is mainly used to evaluate the odor pollution. In the field of occupational health, no evaluation method for the health impact of odor substances has been established.
