Total residue as well as fractions of the centrifuged gradient were extracted with hexane and examined by gas chromatography for the presence of chlorinated hydrocarbon pesticides. Hexane extracts of total residues were also examined by thin-layer chromatography. Lindane and endrin were shown, by gas-liquid chromatography and thin-layer chromatography, to be associated with microparticles. These and other pesticides appeared to be selectively associated with microparticles of different densities, when gas-liquid chromatography was used, although concentrations were below the detection limits required for confirmation by thin-layer chromatography. Samples taken at different times from different locations in Lake Erie revealed different associations with hexane-soluble electron-capturing compounds.<\/jats:p>","DOI":"10.1126\/science.166.3907.878","type":"journal-article","created":{"date-parts":[[2006,10,5]],"date-time":"2006-10-05T12:14:21Z","timestamp":1160050461000},"page":"878-879","source":"Crossref","is-referenced-by-count":13,"title":["Microparticulates: Isolation from Water and Identification of Associated Chlorinated Pesticides"],"prefix":"10.1126","volume":"166","author":[{"given":"Robert M.","family":"Pfister","sequence":"first","affiliation":[{"name":"Microbial and Cellular Biology, Ohio State UniversitY, Columbus 43210"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patrick R.","family":"Dugan","sequence":"additional","affiliation":[{"name":"Microbial and Cellular Biology, Ohio State UniversitY, Columbus 43210"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James I.","family":"Frea","sequence":"additional","affiliation":[{"name":"Microbial and Cellular Biology, Ohio State UniversitY, Columbus 43210"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"221","reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"crossref","first-page":"406","DOI":"10.1021\/jf60111a020","volume":"8","year":"1960","unstructured":"BOWMAN, M.C., SOLUBILITY OF CARBON-14 DDT IN WATER, JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY 8: 406 (1960).","journal-title":"JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY"},{"key":"e_1_2_1_2_1","unstructured":"Breidenback A.
