Overview

Parathion-ethyl, also known as O,O-Diethyl O-(4-nitrophenyl) phosphorothioate, is an organophosphate insecticide and acaricide. It was originally developed by IG Farben in the 1940s and is highly toxic to non-target organisms, including humans. Due to its high toxicity, its use has been banned or restricted in most countries.

Uses

Parathion-ethyl is primarily used as a pesticide, applied by spraying on crops such as cotton, rice, and fruit trees. The usual concentrations of ready-to-use solutions range from 0.05 to 0.1%. However, its use on many food crops is banned due to its high toxicity.

Regulatory

Parathion-ethyl has been banned or restricted in many countries due to its high toxicity. In the EU, it was banned after 2001, and in Switzerland, it is no longer approved as a pesticide. It is classified by the World Health Organization as Toxicity Class Ia (extremely hazardous).

Monitoring

Monitoring of parathion-ethyl residues is essential to ensure compliance with regulatory limits. Laboratories conducting food and environmental analysis require high-purity reference materials to accurately measure residue levels.

Health Impact

Parathion-ethyl is a cholinesterase inhibitor, disrupting the nervous system by inhibiting acetylcholinesterase. Symptoms of poisoning include headaches, convulsions, poor vision, vomiting, abdominal pain, severe diarrhea, unconsciousness, tremor, dyspnea, and pulmonary edema. Long-term exposure can lead to peripheral neuropathy and paralysis.

Environmental Impact

Parathion-ethyl is highly toxic to bees, fish, birds, and other wildlife. It is classified as a persistent organic pollutant and poses significant risks to non-target organisms in the environment.

Safety Measure

Handling parathion-ethyl requires strict safety measures, including the use of protective gloves, clothing, and respirators with organic-vapour cartridges. Industrial safety protocols include special ventilation, continuous air contamination measurement, and frequent analysis of workers' serum acetylcholinesterase activity.

Analytical Standards
