Accumulation and dynamic change of polycyclic aromatic hydrocarbons(PAHs)in wastewater irrigated soils

Abstract

Abstract: The analysis of 14 polycyclic aromatic hydrocarbons(PAHs)in wastewater irrigated soils shows that in general,soils at up stream of irrigation channel have highest accumulation of PAHs,the second is the soils at the mid stream,and those at the down stream are similar with control.But in Shenfu area irrigated with petroleum wastewater,the accumulation of PAHs is found in all soils at up ,mid and down streams of irrigation channel.Application of wastewater during rice growing season can increase the total amount of PAHs in soil,the trend of increase or decrease of each pollutant is different.

Key words: Polycyclic aromatic hydrocarbons(PAHs), Soil, Accumulation, Wastewater irrigation, rural settlement landscape, fractal theory, spatial characteristics, Xiamen
