“…Soil organic matter (OM %) was observed to be positively connected with the total concentration of pesticides (r = 0.225), demonstrating that the adsorption of pesticides could be upgraded by soil organic matter. This correlation was also found in previous studies of agricultural soil [14] , [37] , [45] , [46] , [47] . Soil organic matter is a vital factor affecting pesticide behavior in soils [7] .…”

“…PC2 was predominately composed by heptachlor-epoxide, its parent heptachlor, aldrin, methoxychlor and β-endosulfan, and accounted for 23.4% of the total variance. This cluster of OCPs were associated with their recent usage as alternative of DDTs dated after 1990s in agricultural activities (Niu et al 2016). They were found dominant in the 1st subsurface layers at F1, M1, A1, and at F4 (where was once the surface layer before being covered by the dredged sediments), and decreased in the order of YJF>YJS>YJM.…”

The occurrence and distribution of 19 organochlorine pesticides (OCPs), together with microbial ester-linked fatty acid methyl ester (EL-FAME) profiles were investigated in sediments from an abandoned oxidation pond of Ya-Er lake, China, which had been heavily polluted by hexachlorocyclohexanes (HCHs) and chlorobenzenes in 1980s. Subsurface sediment samples were taken from five sediment cores along the transect running from lakeshore to lakebed. The concentration of total OCPs ranged from 29.8 to 941.8 ng g-1 dw, with a mean value of 193.3 ng g-1 dw. Hexachlorobenzene (HCB), HCHs and dichlorodiphenyl-trichloroethanes (DDTs) were the three dominant OCP classes, accounting for 26.5%-97.4%, 1.8%-51.5%, and 0.4%-15.5% of the total, respectively. Hot spots of HCB, HCHs and DDTs were detected in 0.9-2.7 m deep layers of the lakeshore, where was one of the dredged sediment backfill sites for in-situ remediation of the oxidation pond in 2002-2004. High potential risks of HCHs and HCB were still indicated. Historical industrial input (27.2%), recent agricultural input (14.7%), and persistent residuals (14.3%) were the three major identified sources of OCPs, using Absolute Principal Component Scores-Multiple Linear Regression (APCS-MLR). Redundancy analysis of microbial EL-FAME profiles and nine dominant OCPs revealed that the spatial variation in microbial community structure was significantly corresponded with the OCP composition. This is the first study highlighted the concern on historical industrial inputs of OCPs in subsurface sediments of the lakeshore disposal zone. The findings could help to distinguish the artificial backfill sediments from natural polluted sediments for optimization of further desilting plans.
