随着全球工业的飞速发展,工业废弃物的排放、农药和重金属制品的使用不断增多,导致了重金属、有机物等污染物在环境中的富集。这些污染物通过各种途径最终会影响生态系统的生物多样性和人类的健康。因此,近年来国内外学者越来越关注污染物对生态系统的破坏和对生物的毒害作用及其作用机制,逐渐筛选出一些操作简单、成本低廉、测试周期较短的生物指示物和模式生物进行污染物的检测和评价,例如线虫、斑马鱼、大型蚤、蚯蚓等。线虫不仅是土壤中的后生生
With the rapid development of global industry, the discharge of industrial waste, the increasing use of pesticides and heavy metal products have led to the enrichment of pollutants such as heavy metals and organic pollutants in the environment. Through various channels, these pollutants will eventually affect the biodiversity and human health of ecosystems. Therefore, in recent years, scholars at home and abroad pay more and more attention to the destruction of ecosystem and the poisoning effect on organisms and their mechanism of action, and gradually screened out biological indicators and model organisms with simple operation, low cost and short test period For contaminants detection and evaluation, such as nematodes, zebrafish, fleas, earthworms and so on. Nematodes are not only epigenetic in the soil
