TheChgH-GFP strain of the teleost medaka contains a regulatory region of the estrogen-responsive choriogenin H (chgH) gene fussed to the green fluorescent protein (GFP) gene. The strain was developed for the identification of environmental estrogens by noninvasive analysis of GFP fluorescence. In the present study, a quantification method for GFP by image analysis was establishedand applied to ...
Present study reports the response of zebrafish embryos exposed in vivo to graded concentrations of Nonylphenol (NP), ranging from high lethal levels to lower, more environmentally relevant levels. Embryos treated with NP showing developmental abnormalities and morphological alterations in a dose-dependent pattern. Results suggest that early exposure to NP can cause direct and delayed mortaliti...
Flexocleaners.com and The Sierra Club urge the Environmental Protection Agency (EPA), state agencies and corporations to eliminate the use of the cleaning agent, nonylphenol ethoxylates (NPEs), in the industrial and domestic laundry detergent used in the United States. NPE metabolites often pass through wastewater treatment plants at a concentration that has been shown to cause harmful effects ...
2,6-Di-tert-butyl-4-nonylphenol(DTBNP) was synthesized from 4-n-nonyl phenol and isobutylene, etc. using self-made composite super acid as catalyst. The appropriate technology conditions are as follows: reaction temperature is 60-80 , reaction time is 4h, n 4-n-nonyl phenol : n Isobutylene = 1: 2 and the amount of catalysts is 0.019% of the quantity of 4-n-nonyl phenol reactant, the yield can r...
