Popis: | One chlorinated anisole and three chlorinated veratroles have been identified in extracts of Athabasca River water collected in the winter downstream from a bleached kraft pulp mill effluent. Their potential for causing off-flavors in the receiving waters was evaluated. The average concentration of 2,4,6-trichloroanisole was about 1 ng/L, close to the odor threshold concentration in water. The average concentrations of 4,5-dichloroveratrole, 3,4,5-trichloroveratrole, and tetrachloroveratrole were 7, 7, and 1 ng/L, respectively, 2-4 orders of magnitude below their odor threshold concentrations. Chemical structure appears to be more important than volatility from water (Henry's constant) in determining odor threshold concentration |
