Determination of Henry's law constants of organochlorine pesticides in deionized and saline water as a function of temperature

Abstract: The Henry's law constant (H) is an important parameter that is required to estimate the air-water exchange of semivolatile organic compounds. Henry's law constants for 17 banned/restricted/currently used organochlorine pesticides (OCPs) were experimentally determined using a gas-stripping technique in deionized and saline water (3%) over a temperature range of 5-35 1C. H values (at 25 1C) ranged between 0.06670.037 Pa m 3 mol À1 (endosulfan II) and 62.0724.2 Pa m 3 mol À1 (heptachlor) in deionized water while … Show more

“…Salting-out constants (K s , L/mol) for OCPs were calculated with the method by (Xie et al, 1997). The calculated H values were comparable with results (b 12%) measured by (Cetin et al, 2006). The literature sources of the H values in salt water and the corresponding temperature values are listed in Table S4 (Cetin et al, 2006;Kucklick et al, 1991;Qiu et al, 2008;Sahsuvar et al, 2003;Shen and Wania, 2005) .…”

Theoretically, where f a /f w = 1 at air-water equilibrium, f a /f w > 1 indicates net deposition from air to water, and f a /f w b 1 indicates net volatilization from the water.…”

“…Salinity and temperature correction was performed as described elsewhere. 33 Data on H′ values and temperature dependence were taken from refs 34 and 35. K ol is the overall mass transfer coefficient accounting for the contributions from the mass transfer coefficients of the water layer and the air layer, namely, k w and k a , as follows:…”
