High-purity reference materials for accurate residue analysis.

Overview

Leptophos, also known as O-(4-Bromo-2,5-dichlorophenyl) O-methyl phenylphosphonothioate, is an organophosphate compound. It appears as a stable white solid at room temperature and has been used primarily as a pesticide and fungicide for crops such as rice, cotton, fruit, and vegetables.

Uses

Leptophos was used extensively as a pesticide and fungicide until its use was discontinued in many countries due to its high toxicity. It was primarily applied to control pests in agricultural settings.

Regulatory

Leptophos was discontinued in the USA in 1975 due to its toxic effects. However, it continued to be used in some countries until the early 1980s. It was never registered for domestic use by the Environmental Protection Agency (EPA) but was exported to various countries.

Monitoring

Monitoring the presence of Leptophos in environmental samples is crucial due to its persistence and toxicity. Laboratories conducting food and environmental analysis must ensure compliance with regulatory limits using high-purity reference materials.

Health Impact

Human Toxicity

Leptophos is an irreversible inhibitor of cholinesterases, leading to various toxic effects. Symptoms of exposure include skin rash, respiratory issues, systemic effects like nausea and vomiting, eye irritation, and central nervous system symptoms such as trembling hands and difficulty in seeing.

Environmental Impact

Effects on Wildlife

Leptophos has shown severe toxic effects on wildlife, including the death of over 1000 water buffaloes in Egypt in 1971. Its impact on various animal species has led to significant ecological concerns.

Safety Measures

Due to its high toxicity, handling Leptophos requires stringent safety measures. Personal protective equipment (PPE) and proper disposal methods are essential to prevent exposure and environmental contamination.

Regulation

Leptophos is regulated under various international guidelines due to its toxic nature. Compliance with these regulations is mandatory to ensure safety and minimize environmental impact.
