The occurrence and distribution of five groups of antibiotics were investigated in the surface water of Yangtze Estuary over four seasons. Of the 20 antibiotics, only sulfamerazine was not detected at all sampling sites, indicating widespread occurrence of antibiotic residues in the study area. Detection frequencies and concentrations of antibiotics were(More)

This article presents a simple and universal analytical method for the simultaneous analysis of bisphenol S (BPS), bisphenol F (BPF), bisphenol A (BPA), bisphenol B (BPB), bisphenol AF (BPAF), tetrachlorobisphenol A (TCBPA), and tetrabromobisphenol A (TBBPA) in environmental water (river water, sewage) and solid samples (sediment, sludge) based on liquid(More)
Total HCHs' and total DDTs' levels in surface sediments (SS) ranged from 0.5 to 17.5 ng g(-1) and from 0.9 to 33.1 ng g(-1), averaged 6.0 and 8.2 ng g(-1), respectively. Total HCHs' and total DDTs' levels in suspended particulate matters (SPM) varied from 6.2 to 14.8 ng g(-1) with a mean value of 12.3 ng g(-1) and were from 3.4 to 25.7 ng g(-1) with an(More)
A sensitive and specific method for determination of the residues of 50 anabolic hormones in muscle (pork, beef, shrimp), milk and pig liver was developed. Analytes were separated and acquired by liquid chromatography coupled with an electrospray ionization tandem mass spectrometer (LC-ESI-MS/MS). Target compounds were simultaneously extracted with methanol(More)
Denitrification is an important pathway of nitrogen removal and nitrous oxide (N2O) production in estuarine and coastal ecosystems, and plays a significant role in counteracting aquatic eutrophication induced by excessive nitrogen loads. Estuarine and coastal environments also suffer from increasing antibiotic contamination because of the growing production(More)
Polycyclic aromatic hydrocarbons (PAHs) concentrations were determined in sediments and three types of wetland plants collected from the intertidal flats in the Chongming wetland. The concentration of total PAHs in sediments ranged from 38.7 to 136.2 ngg(-1). Surface sediment concentrations were higher in regions with plant cover than in bare regions.(More)
Bisphenol AF (BPAF), an endocrine disrupting chemical, can induce estrogenic activity through binding to estrogen receptor (ER). However, the metabolism of BPAF in vivo and the estrogenic activity of its metabolites remain unknown. In the present study, we identified four metabolites including BPAF diglucuronide, BPAF glucuronide (BPAF-G), BPAF glucuronide(More)
The occurrence and distribution of six selected estrogen compounds were investigated in samples of surface water, suspended particulate matter (SPM), and sediment in the Yangtze Estuary and its coastal areas over four seasons. With the exception of 17α-ethinylestradiol (EE2), all estrogens were detected at least once in all three phases with bisphenol A(More)
Thirty-eight short peptaibols in a microheterogeneous mixture derived from the fermentation broth of a marine-derived fungus Trichoderma asperellum were determined using ultrahigh pressure liquid chromatography in combination with electrospray-ionization tandem mass spectrometry (UHPLC-ESIMS/MS) techniques, including thirty-two new peptaibols namely(More)
