Influence of Phenanthrene on Cadmium Toxicity to Soil Enzymes and Microbial Growth

摘要

Background. Many contaminated sites contain a variety of toxicants. Risk assessment and the development of soil quality criteria therefore require information on the interaction among toxicants. Interactions between heavy metals are relatively well studied, but little is known about those between heavy metals and polycyclic aromatic hydrocarbons (PAHs).
