Persistence and toxicity of alkyllead salts to anaerobic nitrogen transformations in soil

The production of nitrous oxide, ethylene, and carbon dioxide, indices of general microbial activity, was determined from soil samples in the presence of different concentrations of methyl or ethyllead salts. In the presence of added nitratem glucose, and acetylene, alkyllead salts only marginally i...

Description
Summary:The production of nitrous oxide, ethylene, and carbon dioxide, indices of general microbial activity, was determined from soil samples in the presence of different concentrations of methyl or ethyllead salts. In the presence of added nitratem glucose, and acetylene, alkyllead salts only marginally inhibited N sub( 2)O, ethylene, and CO sub(2) accumulation in the head space above soil slurries which were incubated anaerobically for up to 10 d. The same levels of alkyllead toxicants modified the accumulation of these gases above incubations of supernatant from soil-water suspension.
