Popis:	Recently, it have been reported that many clinical cases have injested insecticides and herbicides either for the purpose of suicide or by mistake, and thet these agricaltural chemicals poison the soil, especially rivers or lakes. Removal of these compounds is thus needed. In this regard, we report herein the application of polyamino acids for the adsorption of these agricultural chemicals by using the quartz-crystal microbalance (QCM) method.The homopolyamino acids exhigbit a high affinity to malathion. Poly (Leu) adsorbed an equal mass of cyanophos and trifluralin. Accordingly, polyamino acids are expected to be useful as adsorbents for organic phosphorous insecticides and herbicides.
