Preservation of organics. Part I, Stability of organochlorinated insecticides in preserved natural water samples / by H.B. Lee, P.D. Leishman, S. Todd and A.S.Y. Chau. : En13-5/86-219E-PDF

"This study monitored the stability of 19 common organochlorinated insecticides (OCs) in fortified water-samples from five regions. The study was implemented in two parts. A pilot study was designed to evaluate the efficacy of two potential preservatives, i.e. copper sulfate and chloroform, for OCs. Using Lake Ontario water as a typical sample, results in the pilot study indicated that chloroform was a more effective preservative than copper sulfate for OCs in water. In the full scale study, subsamples of the five regional waters were fortified, preserved with chloroform, and stored at 4‘C in the dark. The stability of OCs in the waters was monitored by analyzing the samples at 0-time, as well as after 3, 6, 10 and 15 weeks of storage. Results in the full scale study showed that, except for a few cases, the OCs in the preserved water samples were stable over the 15-week study period. The stability of endrin in these water samples was unknown because of erratic recoveries"--Abstract.
