Distribution, potential sources and ecological risks of two persistent organic pollutants in the intertidal sediment at the Shuangtaizi Estuary, Bohai Sea of China

Levels, Sources and Potential Risks of Polychlorinated Biphenyls and Organochlorine Pesticides in Sediments of Qingduizi Bay, China: Does Developing Mariculture Matter?

“…Exogenic organic pollutants tend to accumulate in fatty tissue and are toxic to aquatic organisms because they are lipophilic (Zhu et al, 2015). The evaluation of potential ecotoxicological risks of POPs in estuarine and coastal areas has raised substantial concerns (Tolosa et al, 1995;Yuan et al, 2017). Ecological risk assessment is a useful tool to analyze and evaluate the adverse ecological effects caused by environmental contaminants.…”

Expression Profile of Hydroxysteroid Dehydrogenase-like 2 in Polychaete Perinereis aibuhitensis in Response to BPA

“…P. aibuhitensis (1.5–2.5 g wet weight) was collected from Liaodong Bay in Panjing in China (121°35′ E, 40°45′ N), a relatively unpolluted site with a low ecological risk of BPA [ 31 ]. The animals were transferred to the laboratory and acclimated for a week before we initiated the experiment.…”

Expression profile of a novel glutathione S-transferase gene in the marine polychaete Perinereis aibuhitensis in short-term responses to phenanthrene, fluoranthene, and benzo[α]pyrene

“…P. aibuhitensis (1.5-2.0 g wet weight) was collected at a low tide from the Liaohe Estuary, Liaoning Province, China, a relatively unpolluted site with a low ecological risk in PAHs (Zhang et al, 2016;Yuan et al, 2017). Along with the sediment from the same sampling site, the animals were transferred from the field to our laboratory and gently placed in glass tanks (50 cm × 40 cm × 40 cm) with seawater and origin sediment (Sun et al, 2009).…”
