农药污染场地修复过程中近地面大气气态污染物含量变化特征及影响因素
Variation characteristics and influence factors of near ground atmospheric gaseous pollutants during the remediation process of typical pesticide site
摘要
Abstract
[Objectives] A typical pesticide plant site undergoing soil remediation was analyzed comprehensively for its characteristics in soil contamination and remediation engineering processes.[Methods] Air samples were taken and analyzed throughout the remediation process.The composition and concentrations of gaseous pollutants were studied with statistical methods such as correlation analysis and regression.[Results] Results indicated that main pollutants in the atmosphere include styrene,toluene,ethylbenzene,difluordichloromethane,chloroform,1,4-dichlorobenzene,1,3-dichlorobenzene,chlorotoluene,cyclohexane,ethyl acetate,2-butanone and carbon disulfide.The level of total volatile organic compounds (TVOCs) during the later stage of remediation (from June 2014 to Janurary 2015) was significantly higher than that of the earlier stage(from Janurary 2014 to June 2014).[Conclusions] The volume of excavated soil was the key factor controlling the concentration of atmospheric pollutants.Increased excavation volume led to higher concentration of atmospheric pollutants.Air temperature and wind speed were also controlling factors.Usually,at higher air temperature and lower wind speed,higher contamination level was detected.关键词
