The Acute Toxicity of Chlorobenzene on Eisenia foetida during Soil Pollution

摘要

Under simulated conditions in the laboratory, the natural soil was used to explore the bio-indicators of Eisenia foetida for chlorobenzene toxic effect. These indicators included weight, protein content of earthworms. As a result, the weight and protein content of earthworms were inhibited when exposed. Under the action of Chlorobenzene, the activities of earthworm improved the content of soil ammonium nitrogen and available potassium, but showed no regular effects on that of organic matter and available phosphorus; In addition, there was an a certain correlation between the earthworm biochemical indicators and the content of soil nutrients. In order to enhance the sensitivity and effectiveness of the ecotoxicity assessment of soil pollutant, it should be used a combined multi-time and multi-index monitoring method.
