Ferrey, Mark L. published the artcilePharmaceuticals and other anthropogenic chemicals in atmospheric particulates and precipitation, SDS of cas: 117-96-4, the main research area is contaminants of emerging concern airborne particulate precipitation atm transport; Air; Atmospheric transport; Contaminants of emerging concern; Precipitation; Surface water.
Air and precipitation samples were analyzed by liquid chromatog. tandem mass spectrometry (LC-MS/MS) and gas chromatog. mass spectrometry (GC-MS) for pharmaceuticals, personal care products, and other com. chems. within the St. Paul/Minneapolis metropolitan area of Minnesota, U.S. Of the 126 chems. analyzed, 17 were detected at least once. Bisphenol A, N,N-diethyl-meta-toluamide (DEET), and cocaine were the most frequently detected; their maximum concentrations in snow were 3.80, 9.49, and 0.171 ng/L and in air were 0.137, 0.370, and 0.033 ng/m3, resp. DEET and cocaine were present in samples of rain up to 14.5 and 0.806 ng/L, resp. Four antibiotics – ofloxacin, ciprofloxacin, enrofloxacin, and sulfamethoxazole – were detected at concentrations up to 10.3 ng/L in precipitation, while ofloxacin was the sole antibiotic detected in air at 0.013 ng/m3. The X-ray contrast agent iopamidol and the non-steroidal anti-inflammatory drug naproxen were detected in snow up to 228 ng/L and 3.74 ng/L, resp., while caffeine was detected only in air at 0.069 and 0.111 ng/m3. Benzothiazole was present in rain up to 70 ng/L, while derivatives of benzotriazole – 4-methylbenzotriazole, 5-methylbenzotriazole, and 5-chlorobenzotriazole – were detected at concentrations up to 1.5 ng/L in rain and 3.4 ng/L in snow. Nonylphenol and nonylphenol monoethoxylate were detected once in air at 0.165 and 0.032 ng/m3, resp. Although the sources of these chems. to atm. are not known, fugacity anal. suggests that wastewater may be a source of nonylphenol, nonylphenol monoethoxylate, DEET, and caffeine to atm. The land-spreading of biosolids is known to generate PM10 that could also account for the presence of these contaminants in air. Micro-pollutant detections in air and precipitation are similar to the profile of contaminants reported previously for surface water. This proof of concept study suggests that atm. transport of these chems. may partially explain the ubiquity of these contaminants in the aquatic environment.
