监测研究表明，美国的城市地表溪流普遍受到农药污染，有机磷和氨基甲酸酯的污染特别令人关切，因为它们对水生生物具有毒性。研究了4种常见有机磷和氨基甲酸酯类杀虫剂在美国南加州城市河流沉积物中的降解和吸附。在沉积物中，马拉硫磷在好氧和厌氧条件下均能迅速降解，其半衰期为t（1/2）
Monitoring studies show that urban surface streams in the United States are commonly contaminated with pesticides, and contamination by organophosphates and carbamates is of particular concern because of their aquatic toxicity. The degradation and sorption of four common organophosphate and carbamate insecticides were studied in urban creek sediments from southern California, USA. In sediment, malathion was quickly degraded under either aerobic or anaerobic conditions, with a half-life (t(1/2))
