Aerobic biodegradation studies of nonylphenol ethoxylates in river water using liquid chromatography-electrospray tandem mass spectrometry

Article Abstract:

Nonylphenol ethoxylates that are normally released from industrial production into wastewater are studied in a controlled environment to determine the process of degradation. The author's findings are graphed, showing the rates at which the derivitaves of nonylphenol ethoxylates are produced. A distinct lack of the metabolite nonylphenol after degradation is discussed.

Determination of endocrine-distrupting phenolic compounds and estrogens in surface and drinking water by HRGC-(NCI)-MS in the picogram per liter range

Article Abstract:

Water samples from the effluents of three municipal sewage treatment works in southern Germany are analyzed through solid phase extraction (SPE) on a cartridge containing the sorbent LiChrolut EN, and the contents are determined through high-resolution gas chromatography with negative chemical ionization mass spectrometric detection (HRGC-(NCI)-MS) in the selected ion mode (SIM). Endocrine-disrupting estrogens are found in the aquatic environment and in drinking water at significant levels, despite water treatment processes.

The Medieval Metal Industry Was the Cradle of Modern Large-Scale Atmospheric Lead Pollution in Northern Europe

Article Abstract:

Researchers found that sediment in lakes in Sweden show a pronounced increase in lead contamination during the Roman period, a decrease after 400A.D., and an increase beginning in 900A.D. Tables and figures support their theory that most lead deposition came from present-day Germany.
