Abstract

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.

摘要

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。
