Chlordane is a synthetic organochlorine pesticide that belongs to the group of chlorinated cyclodiene. They are commonly resistant to photolytic, chemical, and biological degradation, and have relatively long half-lives. Chlordane manufactured as a technical form is composed of more than 120 structurally related compounds. The predominant isomers in technical chlordane are cis-chlordane (19%), trans-chlordane (24%), cis-nonachlor (2.7%), trans-nonachlor (9.7%), and heptachlor (10%).

Chlordane has to be monitored in the Multiannual Control Programmes for Pesticides Residues (MACP), run within the EU and EFTA in/on products of animal origin. Maximum residue levels (MRLs) have been set according to Reg (EC) No 149/2008 for chlordane (sum of cis-and trans chlordane) for various products of plant and animal origin from 0.01 to 0.005 mg/kg.

Technical chlordane was used mostly as an agricultural pesticide on corn and citrus, for home lawns and gardens, as well as a termiticide in house foundation. Chlordane blocks the gamma-aminobutyric acid (GABA)-gated chloride channels in the central nervous system, resulting in hyperexcitation and convulsions.

The use of chlordane as a pesticide has been banned in the EU since 1981 by Council Directive 79/117/EEC of 21 December 1978 which prohibited the placing on the market and use of plant protection products containing certain substances.

Anwendung

It is intended to be used as a certified reference material (CRM) for calibration in chromatography and other analytical techniques. Chlordane in CRM may also find its use as described below:

• Study of joint toxic effects of polystyrene nanoparticles and chlordane and hexachlorocyclohexane pesticides on Caenorhabditis elegans
• Development of biomonitoring equivalents for chlordane and toxaphene with application to the general Canadian population
• To study chlordane, PCBs, and synthetic musk fragrances in a backwater area in the Upper Mississippi River and Iowa River
• QuEChERS method and a single instrumental analysis to detect a broad range of persistent organic pollutants (POPs) in white sturgeon liver and gonad tissues as an indication of exposure
• To investigate the effect of chlordane, heptachlor, and mirex, on hormonal regulation of the force of myometrial contractions in cow
