High-purity reference materials for accurate and reliable residue analysis of Methamidophos.
Overview
Methamidophos, known by its IUPAC name O,S-Dimethyl phosphoramidothioate, is an organophosphate insecticide. It is widely used in agriculture for pest control on crops such as potatoes and rice. Methamidophos is recognized for its high toxicity and effectiveness in pest management.
Uses
Methamidophos is primarily used in rice fields in China and other rice-producing countries like Thailand, Malaysia, and the Philippines. It is also used on various crops in countries such as Spain, the United States, Japan, and Australia. Due to its high toxicity, its use is being phased out in several countries, including Brazil and the United States.
Regulatory
The use of Methamidophos is heavily regulated due to its toxicity. In 2009, all uses in the United States were voluntarily canceled. It is classified as a WHO Toxicity Class 1b, indicating it is highly hazardous. Regulatory bodies require strict compliance with safety measures when handling and applying this pesticide.
Monitoring
Monitoring Methamidophos residues in food and the environment is crucial for ensuring safety and compliance with regulatory limits. Laboratories conducting residue analysis rely on high-purity reference materials to achieve accurate and reliable results. These reference materials are essential for maintaining the integrity of analytical data.
Health Impact
Methamidophos is a cholinesterase inhibitor, which means it interferes with the normal function of the nervous system. It is rapidly absorbed through the stomach, lungs, and skin, and is primarily eliminated through urine. Exposure can lead to severe health effects, including acute toxicity with LD50 rates of 21 and 16 mg/kg for male and female rats, respectively.
Environmental Impact
Methamidophos has a significant environmental impact due to its persistence and toxicity. It breaks down in soil within 6.1 days in sand but can persist for up to 309 days in water at pH 5.0. Sunlight accelerates its breakdown. It is absorbed by plants through roots and leaves, and can accumulate in fish and other organisms, posing risks to wildlife and ecosystems.
Safety Measures
Handling Methamidophos requires strict adherence to safety protocols. The GHS labelling includes hazard statements H300, H311, H330, and H400, indicating it is fatal if swallowed, in contact with skin, or if inhaled, and very toxic to aquatic life. Precautionary statements include P260, P264, P270, P271, P273, P280, P284, P301+P310, P302+P352, P304+P340, P310, P312, P320, P321, P322, P330, P361, P363, P391, P403+P233, P405, and P501.
