The occurrence of endocrine disrupting chemicals (EDCs) is a major issue for marine and coastal environments in the proximity urban areas. EDCs Pearl River Delta region well documented but specific data related to Macao unavailable. levels bisphenol-A (BPA), estrone (E1), 17α-estradiol (αE2), 17β-estradiol (E2), estriol (E3), 17α-ethynylestradiol (EE2) were measured sediment samples collected a...

Correspondence to be addressed to: Dr.T.G. Shrivastav, E-mail:[email protected] Summary Preparation of horseradish peroxidase (HRP) carbamide that is HRP linked to urea (HRP-carbamide/HRP-U) is demonstrated and its potential application in the development of enzyme immunoassays (EIAs) for haptens is described. In this new strategy, the lysine residues of HRP were acylated and then acylat...
Steroid hormones pose potential risks to fish and other aquatic organisms at extremely low concentrations. To assess the factors affecting the release of endogenous estrogenic and androgenic steroids from feedlots during rainfall, runoff, and soil samples were collected after simulated rainfall on a 14-steer feedlot under different rainfall rates and aging periods and analyzed for six steroid h...
