洗涤剂磷对日本三角涡虫生长的影响

Impact of Phosphorus in Detergent on the Growth of Dugesia Japonica

观察了含磷量不同的洗衣粉溶液对日本三角涡虫生长的影响。结果表明:无论洗衣粉含磷量高低对日本三角涡虫生长均有毒害影响,且高磷洗衣粉对涡虫的毒害远大于低磷洗衣粉,磷量的增加与涡虫死亡率呈正相关。实验中,自来水对照组对涡虫生长无影响。

Impacts of different phosphorus content in detergent on the growth of Dugesia Japonica are studied. The results show that all detergents have harm and poisonous impact, and more poisonous with higher phosphorus content. However, impacts from running water seem harmless on the Dugesia Japonica.
