Land degradation induced by soil erosion is widespread in semiarid regions globally and common the agro–pastoral ecotone of northern China. Most researchers identify wind water as independent processes, there a lack research regarding relative contributions interactions between them what referred to here compound (CSE). CSE may occur situations where more effectively erodes surface already subj...

Measurement of ethoxyresorufin-O-deethylase (EROD) activity in fish is a well-established in vivo biomarker of exposure to certain planar halogenated and polycyclic aromatic hydrocarbons (PHHs and PAHs) and other structurally similar compounds (Bucheli and Fent 1995; Stegeman and Hahn 1994). EROD is a highly sensitive indicator of contaminant uptake in fish, providing evidence of receptor-media...

Long-term programmes like the UK Clean Seas Environmental Monitoring Programme (CSEMP) rely on biological effects techniques, including biomarkers, to assess if chemical pollutants are affecting sentinel species in aquatic environment. In this study, we have applied mixed and fixed effect linear models long-term CSEMP dataset (2005-2018) evaluate factors such as region (location), sex, age, gon...

We previously reported that in vivo cimetidine inhibits hepatic microsomal enzyme activities mediated by cytochrome P450 (CYP)2C11 and at least one other CYP enzyme but does not inhibit CYP2A1-, CYP2B- or CYP3A-mediated activities in adult male rats. To investigate the effects of in vivo cimetidine on CYP1A1, cimetidine (150 mg/kg i.p.) or saline was administered to beta-naphthoflavone-induced ...

Juvenile areolated grouper (Epinephelus areolatus) were exposed to two levels of dietary benzo[a]pyrene (BaP; 0.25-12.5 microg/g body wt/d) for four weeks, followed by four weeks of depuration. Significant increase in hepatic ethoxyresorufin O-deethylase (EROD) activities was found after one week, preceding an increase in lipopigments (as measured by quantitative transmission electron microscop...
