Albero, Beatriz; Perez, Rosa Ana; Sanchez-Brunete, Consuelo; Tadeo, Jose Luis published the artcile< Occurrence and analysis of parabens in municipal sewage sludge from wastewater treatment plants in Madrid (Spain)>, Category: chlorides-buliding-blocks, the main research area is sewage sludge paraben analysis occurrence GC tandem mass spectrometry; wastewater treatment sludge paraben analysis occurrence Madrid Spain.
A rapid method for determination of 7 parabens and 2 chlorinated byproducts in sewage sludge was developed based on matrix solid-phase dispersion and gas chromatog.-tandem mass spectrometry. The anal. procedure showed good recoveries that ranged from 80-125%, with relative standard deviations <12% and low detection limits, ranging from 0.1-2.0 ng g-1 dry weight The developed method was applied to the anal. of sewage sludge collected during 2010 in 19 wastewater treatment plants (WWTPs) located in various urban, industrial, or rural zones in Madrid (Spain). Methylparaben was found in most of the WWTPs sampled (95%) at levels between 5.1-26.2 ng g-1 dry weight and propylparaben was detected in 74% of the WWTPs at levels up to 44.1 ng g-1 dry weight To study the temporal variation of parabens and 2 chlorinated parabens during a 4-yr period, sludge samples were collected from 3 selected WWTPs. The levels of methylparaben encountered were rather constant throughout the sampling period whereas propylparaben levels slightly increased. In one of the WWTPs monitored, isopropylparaben was found at the beginning of the sampling period but its content decreased and was not detected in the 2010 sampling. Journal of Hazardous Materials published new progress about Gas chromatography-tandem mass spectrometry. 3964-57-6 belongs to class chlorides-buliding-blocks, and the molecular formula is C8H7ClO3, Category: chlorides-buliding-blocks.
