The effects of polychlorinated biphenyls (PCBs) on nitrification were examined for pure cultures and natural reservoir samples. PCBs at concentrations greater than 10 microgram liter-1 inhibited nitrification, principally ammonium oxidation, in one of two natural reservoir environments. However, this inhibition could not be reproduced in pure high-cell-density cultures or in previously contaminated reservoir waters. A PCB environmental biotransformation product, p-chlorophenylglyoxylic acid, and p-chloromandelic acid had no effect on nitrification.
针对纯培养物和天然水库样本,研究了多氯联苯(PCBs)对硝化作用的影响。在两种天然水库环境中的一种里,浓度大于10微克/升的多氯联苯抑制了硝化作用,主要是铵氧化作用。然而,在纯的高细胞密度培养物或先前已受污染的水库水中,这种抑制作用无法重现。一种多氯联苯环境生物转化产物,对氯苯甲酰甲酸和对氯扁桃酸,对硝化作用没有影响。
