Organochlorine pesticides: highly persistent compounds in the environment<\/h2>\n

Organochlorine pesticides (OCPs) are synthetic compounds that have long been used to protect crops. They include DDT, lindane, aldrin, chlordane and endosulfan. Thanks to their formidable effectiveness against numerous insect pests, these substances have been used on a massive scale. However, their remarkable chemical stability and their ability to accumulate in living organisms now pose serious health and environmental problems. <\/p>\n

Contaminants under global surveillance<\/h3>\n

Over time, international authorities have recognised the dangers posed by OCPs. So they classified them as persistent organic pollutants (POPs) under the Stockholm Convention. This international treaty provides a strict framework for their use and production, imposing bans and requiring rigorous monitoring campaigns by signatory countries. <\/p>\n

Despite these measures, OCPs remain omnipresent in the environment. Residues are still found in agricultural soils, sediments, certain foodstuffs and in human and animal biological tissues. Their persistence, sometimes over several decades, illustrates the extent of their dispersion, even in regions such as France. <\/p>\n

Rigorous analytical requirements<\/h3>\n

Faced with this situation, laboratories need to use analysis methods that are both sensitive and selective in order to identify and quantify these contaminants in complex matrices. To guarantee reliable results, it is essential to use certified analytical standards during the calibration, method validation and quality control stages. <\/p>\n

Wellington Laboratories offers analysts a wide range of reference materials specifically formulated for OCP analysis. Thanks to their high purity and rigorous traceability, these standards meet the requirements of the main international standards (EPA, ISO, JIS, etc.). <\/p>\n

More specifically, the range includes:<\/p>\n
