为了评估红壤中不同铅化合物对微生物生物量的毒性差异，进行了实验室培养试验铅化合物为氯化铅和醋酸铅，施加的6个不同浓度（w／10－6）为0（背景值），100，200，300，450和600在铅水平相同时，醋酸铅比氯化铅对土壤中微生物生物量碳（Cmic）和微生物生物量氮（Nmic）的降低更为明显土壤中微生物量C／N比和有机碳／微生物量碳比［m（Corg）／m（Cmic）］随着醋酸铅水平的增加而显著提高,而氯化铅在相同水平下，提高的幅度大大减少,这些结果表明，不同铅化合物的溶解度和不同相伴阴离子是决定铅化合物毒性的重要因素.
In order to assess the differences in toxicity of different lead compounds to microbial biomass in red soil, laboratory tests were conducted to determine the lead compounds lead chloride and lead acetate, 6 different concentrations (w / 10-6) of 0 (background) 100, 200, 300, 450 and 600, lead (Pb) was more obvious than lead (Pb) in the soil at the same level of lead. The microbial biomass carbon (Cmic) and microbial biomass N The ratio of organic matter to organic carbon / microbial biomass [m (Corg) / m (Cmic)] increased significantly with the increase of lead acetate level, while the lead chloride level greatly increased at the same level. These results showed that the differences The solubility of lead compounds and the accompanying anions are important factors that determine the toxicity of lead compounds.
