Fruit vegetables heavy metal rapid pesticide residue test

Product Description

Organic phosphorus and carbamate pesticides is currently the largest use of pesticides in China, and more is prohibited in the use of fruits, vegetables. This type of pesticide in the body can be combined with acetylcholinesterase (Ache), and difficult to separate, that Ache activity is inhibited, resulting in nerve conduction of acetylcholine can not be hydrolyzed and accumulated, nervous excitement, symptoms of poisoning and even death. Based on the principle of enzyme inhibition of the enzyme inhibition rate method, the detection principle can be simply expressed as follows: the use of a sensitive enzyme source prepared by the preparation of butyrylcholinesterase as a detection reagent, according to the degree of activity of butyrylcholinesterase to determine the residual pesticide in fruit and vegetable samples.
