Limitation requirements of the EU content chlorpirifos and chlorpyrifos-methyl in agricultural products

To date, hard to imagine agriculture without the use of pesticides. Even in the age of organic production, agricultural producers continue to use pesticides to protect it from injuries and diseases.

Recall that in February 2020, the countries members of the EU approved the Commission's proposal to reduce the maximum allowable level chlorpirifos and related substances chlorpyrifos-methyl in agricultural and food products. This means that from October 2020 to export to the EU oilseeds and grains, which contain more than 0,01 mg/kg specified insecticide, is prohibited.

the Ban stems from research by the European Agency for food safety (EFSA), which deals with the risk assessment of pesticides, which were carried out over the last 20 years. EFSA States that these substances have potential" genotoxic and neurotoxic effects on the human body, in particular, cause nerve pathology in children (significant delays in development in the first years of life).

In Ukraine, preparations on the basis of chlorpyrifos and chlorpyrifos-methyl are actively used for the treatment of most crops, and also as a disinfectant for grain storage.

the Drug accumulates most in sunflower, soybean and rapeseed due to the high oil content in the cultures. Also hlopes and chlorpyrifos-methyl can accumulate in the soil or to settle on culture of dust in granaries, that is, if you have not used the drug culture, but used it to disinfect the composition, the dust will absorb and will contaminantes (Contamination - contamination as a result of the contact, mixing). As a result, the analysis will show the residual amount chlorpirifos in production.

Even tiny concentrations can harm people.

Maintain the new requirements once again confirms that agricultural products should be carefully monitored for pesticides in accredited laboratories, which use contemporary tools for the accurate analysis, provide high sensitivity, selectivity and low limits of quantification (LOQ - 0.005 mg/kg) for a wide range of goods, including grains, beans, oilseeds, vegetable oils, etc.

the Most accurate method of determining chlorpirifos and hlopes-methyl – is a method of using the technology of gas chromatography with tandem mass spectrometry (GC-MS/MS) mode multiple reactions monitoring (MRM).
