Aquatic photodegradation of polychlorinated dibenzofurans: Rates and photoproduct analysis
The aquatic photochemistry of 2,3,7,8-tetrachlorodibenzofuran (T4CDF) and 2,3,4,7,8-pentachlorodibenzofuran (P5CDF) was studied in the laboratory using a xenon light source and under sunlight conditions at 50 N latitude at the Experimental Lakes Area of northwestern Ontario, Canada. Under midsummer sunlight conditions 3H-T4CDF and 14C-P5CDF photolyzed slowly in 25:10 (v/v) distilled water/acetonitrile solutions with rate constants of 0.11¡À0.01 and 0.015¡À0.007 d-1, respectively. Both congeners experienced enhanced degradation rates in lake water, with rate constants of 0.58¡À0.05 and 3.6¡À0.3 d-1. Photoproduct analysis confirmed reductive dechlorination as a degradative pathway for both PCDFs in lake water. Three T4CDF were detected as photoproducts of 23478-P5CDF, with two of these products identified by GC/MS as 2368- and 2348-T4CDF. Similarly, one T3CDF was detected in the photolysis of 2378-T4CDF, although the specific congener was not identified. One polar photoproduct was detected in the photolysis of 23478-P5CDF in lake water. Although the identity of this product could not be confirmed, GC/MS analysis of the TMS derivative suggested a hydroxylated, completely dechlorinated compound with an apparent M+=330 amu. Photolysis of nonchlorinated dibenzofuran in lake water yielded 2,2′-dihydroxybiphenyl as photoproduct, with this product producing a trihydroxybiphenyl, tentatively identified as 2,2′,3-trihydroxybiphenyl, under similar conditions. The results show that reductive dechlorination, C-O cleavage, and hydroxylation of PCDFs and the dibenzofuran nucleus in natural water.
