“…The persistence of lindane in our experiments differs from results obtained by Lichtenstein and Schulz (7), who reported that lindane disappeared rapidly from water, and that the vapors above the water surface were highly toxic to fruit flies. The discrepancy probably arises from the different experimental conditions.…”

“…According to Gunther et al (6) the water solubility of lindane ranges from 7.3 to 14 ppm, depending on temperature and method of determination. This is much greater than the concentration we used but just around that used by Lichtenstein and Schulz (7). In addition, apparent solubilities of pesticides in water tend to increase in the presence of impurities (6), especially biological material, including cell-free enzyme preparations (10).…”

1972. Fate and behavior of five chlorinated hydrocarbons in three natural waters. Can. J. Microbiol. 18: 1393-1398. Water samples removed from two rivers and from the subtidal zone of Georgia Strait in British Columbia were treated with either 0.025 pprn of DDT, lindane, a-chlordane, or y-chlordane, or 0.1 pprn Aroclor 1260 (PCB). The samples were incubated in the laboratory for up to 12 weeks at the temperatures of these natural waters at the time of sampling. Lindane persisted in all water samples throughout the experiment, but large proportions of the other compounds were transported into the atmosphere during incubation except when the containers were sealed. N o metabolic breakdown could be demonstrated. As demonstrated with 14C-y-chlordane, uneven distribution of the pesticides occurred rapidly, but was prevented, or reversed, by addition of a surfactant to the water. Total bacterial counts were generally higher in treated than in untreated water samples. OLOFFS, P. C., L. J. ALBRIGHT et S. Y. SZETO. 1972.

Des echantillons d'eau prClevCs de deux rivikres et de la zone des basses marees dans le Georgia Strait, en Colombie Britannique, furent trait& avec soit 0.025 ppm de DDT, lindane, a-chlordane, y-chlordane, ou 0.1 pprn d'Arochlor 1260 (PCB). Les tchantillons furent incubes dans le laboratoire pour des pkriodes allant jusqu'a 12 semaines, et aux temperatures des eaux naturelles au temps de 1'6hantillonnage. Le lindane persista dans tous les echantillons tout au cours de l'expbience, tandis que de grandes proportions des autres composCs furent transportees dans l'atmosphkre durant l'incubation, excepte lorsque les boites furent fermCes hermktiquement. On n'a pu demontrer de bris mktabolique. Lorsque le 14C-ychlordane fut utilise, on a dCmontrC que les pesticides se distribuent inigalement et rapidement; ce phenomkne est prevenu ou renverse par l'addition d'un surfactant B l'eau. Les comptes bactkriens totales furent genballement plus eleves dans les Cchantillons traites que dans ceux non trait&.

“…Considering that volatilisation results from a pesticide's affinity for the gas phase relative to the aqueous phase, it is expected that by increasing the dissolved organic fraction, the affinity for the aqueous phase increases and thus volatilisation decreases. Such an occurrence was observed by Lichtenstein and Schulz (1970), who found that the addition of soil, algae or a detergent to water reduced the volatility of certain pesticides (but not others). DDT and lindane volatility from water was reduced by the addition of soil,…”

The use of vegetated wetlands for accelerating pesticide removal from agricultural runoff is gaining acceptance as a best management practice. In this study, the dissipation of five cotton pesticidesendosulfan, chlorpyrifos, aldicarb, prometryn and diuron -was quantified in cotton field runoff water contained in glasshouse columns, under light or dark conditions. Two water samples sourced from large, non-vegetated storage dams were compared with two other water samples obtained from vegetated wetlands receiving runoff from cotton fields. All pesticides studied except chlorpyrifos dissipated significantly faster from the storage dam samples than the vegetated wetland samples. Suggested reasons include a greater number of pesticide-degrading microorganisms in the storage dam waters and/or the presence of more organic matter in the wetland samples, limiting contaminant volatilisation and hydrolysis. Exposure to light significantly reduced the rate of endosulfan removal, whereas light increased the rate of chlorpyrifos removal. Half-lives are presented for each pesticide where appropriate.

“…Above this point no significant increase in volatility seems to occur. LICHTENSTEIN and SCHULZ (1970) reported that volatilization of the pesticide O-ethyl-S-phenylethyl phosphonodithioate increased with increasing concentrations in water from 2.5 to 20 p.p.m. at 30° C. These concentrations overlap its water solubility limit (13 p.p.m.…”
