The biodegradability of pollutants introduced into aquatic environments is subject to many variabilities characteristic of microbial processes. Some observations have been reported on studies with p-cresol, methyl parathion, benzo[b]thiophene, dibenzothiophene, 9H-carbazole, quinoline, benzo[f]quinoline, benz[a]anthracene, benzo[a]pyrene, 7H-dibenzo[c,g]carbazole, Mirex, 2,4-dichlorophenoxyacetic acid, Lindane and 1,1-bis(p-chlorophenyl)-2,2,2-trichloroethane analogs. Water reservoirs included a eutrophic stream, a eutrophic pond, an oligotrophic lake and effluents from waste-water treatment plants. The first ten of the above compounds were studied only in aerobic mixed-culture systems, and Mirex was studied with mixed cultures under both aerobic and anaerobic conditions. Examples were presented of the significance of cometabolism, diauxic processes, film fermentations and microbial interactions in biodegradation studies. Caution is advised in protocols regarding biodegradability of pollutants in aquatic environments.
引入水生环境中的污染物的生物降解性受微生物过程的许多变异性影响。已报道了一些关于对甲酚、甲基对硫磷、苯并[b]噻吩、二苯并噻吩、9H-咔唑、喹啉、苯并[f]喹啉、苯并[a]蒽、苯并[a]芘、7H-二苯并[c,g]咔唑、灭蚁灵、2,4-二氯苯氧基乙酸、林丹和1,1-双（对氯苯基）-2,2,2-三氯乙烷类似物的研究观察结果。水体包括一条富营养化溪流、一个富营养化池塘、一个贫营养湖泊以及污水处理厂的废水。上述前十种化合物仅在好氧混合培养系统中进行了研究，而灭蚁灵在好氧和厌氧条件下的混合培养中都进行了研究。文中给出了共代谢、二次生长过程、膜发酵和微生物相互作用在生物降解研究中的重要性的实例。在有关水生环境中污染物生物降解性的实验方案中需谨慎行事。
