A large number of anthropogenic trace contaminants such as pharmaceuticals, their human metabolites and further transformation products (TPs) enter wastewater treatment plants on a daily basis. A mixture of known, expected, and unknown molecules are

Pharmaceuticals and other anthropogenic trace contaminants reach wastewaters and are often not satisfactorily eliminated in sewage treatment plants. These contaminants and/or their degradation products may reach surface waters, thus influencing aquat

Potential aerobic biodegradation mechanisms of the widely used polar, low-adsorptive sulfonamide antibiotic sulfamethoxazole (SMX) were investigated in activated sludge at bench scale. The study focused on (i) SMX co-metabolism with acetate and ammon

The human macrolide antibiotic clarithromycin is widespread in surface waters. Our study shows that its major metabolite 14-hydroxy(R)-clarithromycin is found in surface waters in comparable amounts. This metabolite is known to be pharmacologically a

A HPLC method was developed to investigate and clear up death of fish populations due to surface water pollution with liquid manure or untreated municipal wastewater. The method is based on the determination of four characteristic manure components (

From 1995 to 1998 the concentrations of 4-nitrophenol, 2-methyl-4-nitrophenol, 3-methyl-4-nitrophenol, dinitro-ortho-cresol (DNOC) and 2,4-di-nitrophenol were measured monthly by HPLC in precipitation at eight different locations in Bavaria (Germany)

Herbicide loads of urban and rural waste water treatment plant effluents were calculated over a one-year period by measuring the herbicide concentrations in 14-day mixed samples. More than three quarters of the total herbicide load of the effluent of

An analytical method for the determination of trace amounts of Galaxolide® (HHCB) by HPLC is presented. It is based on the separation of HHCB in different samples by a C18-column and a gradient elution by water and acetonitrile, both containing some
