英文摘要: Bioaccumulation potential and associated ecological risk of sediment-bound DDT and its metabolites (DDXs) and heavy metals in Hailing Bay, a typical mariculture zone along the southern coast of China, were evaluated. The estuarine sediments were co-polluted by DDXs (120–4882 ng/g dry wt.) and heavy metals (292–409 mg/kg dry wt.). Both DDXs and metals in sediment were bioavailable to Nereis succinea, although the biota-sediment accumulation factors were less than 1 except for DDE. Significant transformation of DDT in organism was observed and DDE was the main metabolite. Ecological risk assessment showed that sediment-bound p,p′-DDT and p,p′-DDD frequently exhibited adverse effects on benthic community in the aquaculture zone, and heavy metals would cause moderate to considerable ecological risk, with Cd dominating the risk. The highest risk occurred in the shipyard area, indicating severe pollution and urgent need to control the source of DDT and heavy metals from aquafarming activities. Capsule Estuarine sediments in South China was co-polluted by DDT and its metabolites and heavy metals due to aquafarming activities, which resulted in bioaccumulation of the contaminants in benthic invertebrates and posed potential risk to species at higher trophic levels. © 2016 Elsevier Ltd Citation statistics:
