High-purity reference materials for accurate residue analysis

Overview

Demeton-S-methyl is an organic compound with the molecular formula C₆H₁₅O₃PS₂. It is a colorless to pale-yellow oily liquid primarily used as an organothiophosphate acaricide and insecticide. It was first described in 1950 and widely adopted due to its lower toxicity compared to its predecessor, demeton.

Uses

Demeton-S-methyl was primarily employed in agriculture to control plant-sucking arthropod pests such as aphids, mites, and whiteflies on fruits, vegetables, potatoes, beet, and hops. It was preferred for its ability to be absorbed and distributed within plants, effectively targeting pests.

Regulatory

Due to its high toxicity, Demeton-S-methyl is classified as a highly toxic substance by the World Health Organization and is banned from agricultural use worldwide. It is considered a highly toxic organophosphorus insecticide with strict regulatory limits on its use and residue levels.

Monitoring

Regular monitoring and testing are essential to ensure compliance with regulatory limits. Laboratories use high-purity reference materials to accurately measure residue levels of Demeton-S-methyl in food and environmental samples.

Health Impact

Human Toxicity

Demeton-S-methyl inhibits cholinesterase, leading to an accumulation of acetylcholine, which can impede neurotransmission. Symptoms of toxicity include drowsiness, vomiting, abdominal pain, diarrhea, nausea, fatigue, headache, respiratory problems, salivation, and lachrymation. Chronic exposure can lead to severe health issues, including cardiovascular collapse and death.

Environmental Impact

Effects on Wildlife

Demeton-S-methyl has a high acute toxicity towards aquatic invertebrates, birds, and fish. It does not persist in the environment and is not accumulated by organisms, but its high toxicity poses significant risks to wildlife.

Safety Measures

Appropriate safety measures include wearing protective clothing, using proper ventilation, and adhering to recommended exposure limits. Immediate medical attention is necessary in case of exposure.
