Currently, the issue of food safety is increasingly hot with the many dirty food establishments. The meat, fish, eggs, the milk contaminated with substance weight group β-agonist and exceeded antibiotic residue. Besides vegetables contaminated plant protection drugs also doing the headache of managers as well as increasing consumer fears. We learn about the causes and the detection method of pesticide residues on agricultural products is where !
- WHY HAVE THE REMAIN BALANCE OF PESTICIDES
- Use overdose
- Use of pesticides too strong
- Using the wrong types of pesticides
- Harvest time is not reasonable
- Pesticide pollution
- THE PESTICIDES COMMON CHEMICAL
The drug contains groups of Organochlorines
The drug contains Group Carbamates
The pills contain Synthetic Pyrethroids
The drug contains Group Chiti
The drug contains Group Synthesis inhibitors
In it about 80% the insecticide containing group Carbamates and Organophosphates.
- Organophosphate group affect how people?
- Organophosphate group can survive and move in the air. It affects to the human as a neurotoxin.
- According to statistics 70% chemical pesticides are deadly poison. Reverse cholinergic syndrome can cause death quickly after Organophospate are inhaled, swallowed or absorbed through the skin. It causes muscle failure and falling fast from 1 to 4 day. At the same time it has the effect of destroying honor far neurons from 2 to 3 weeks after tainted.
- Had to 80% the report discusses insecticide exposure around the world. In 2004, There 102,754 exposure cases reported in the U.S..
According to the WHO statistics, there are about 2-3 millions of Organophosphate and Carbamate infections including 20,000 the person who has died.

- Carbamate groups affect how people?
- Carbamate groups can be absorbed through the skin in particular over the scratches and open wound. This group is often not considered as causes of cancer except 2 case with Carbaryl (SEVIN) and Carbofuran (FURADAN) can be combined with a few ingredients in the stomach forming carcinogens.
- One has to prove that it is the cause of the birth defects or reproductive problems on the experimental animal model.
- The types of substances in the groups of Carbamate and Organophosphate
- Carbamate Group:
Aldicarb, Carbofuran, Furadan, Fenoxycarb, Carbaryl, Sevin Ethienocarb, and 2-(1-Methylpropyl)phenyl N-methylcarbamate
- Organophosphate Group
Parathion, Malathion, methyl parathion, chlorpyrifos, diazinon, dichlorvos, phosmet, tetrachlorvinphos, and azinphos methyl
