Abstract:
Rice (Oryza sativa L.) is a staple food for people of India and most parts of the world. Major insect pests reduce yield and quality of rice grain. Cypermethrin is a pesticide which was used in paddy field for the management of major insect pests of paddy plant. It was hypothetically assume that cypermethrin transmitted into paddy plant during the course of pesticide spray. Contamination of paddy harmful for humans beings and other animals because cypermethrin is a carcinogen. For this an experiment (residual analysis) was done to find out quantity of pesticide in rice grain. The aim of research work is find out percentage contamination of rice grain with pesticide which was compared with the other nutrients of rice grain. 5 gram of treated rice crushed as sample, after this passing through centrifugation at 5000 rpm which was further followed by gas chromatography (GC-MS). The Result of this work, there was no contamination of rice grain to cypermethrin. So, it is safe for human consumption and other animals.
