-Before 2006 there was no legal regulation in Germany on the maximum content of HCB in the active ingredient chlorothalonil. However, with the implementation of Directive 91/414/EEC ((Council Directive 91/414/EEC of 15 July 1991 concerning the placing of plant protection products on the market, https://eur-lex.europa.eu/legal-content/en/ALL/?uri=CELEX:31991L0414)), manufacturers had to analyse their technical active substance for possible relevant impurities and, where appropriate, indicate a maximum level. These maximum levels had to be maintained. Information about the levels specified for chlorothalonil for the years 1990 and 1999 for Germany are not known. As described in the FAO specification (2015, p. 49, ((FAO (2015): FAO (Food and Agriculture Organization of the United Nations) Specifications and Evaluations for Chlorothalonil, p 51. http://www.fao.org/agriculture/crops/thematic-sitemap/theme/pests/jmps/ps-new/en/))) Chlorothalonil was reviewed by IPCS (INTERNATIONAL PROGRAMME ON CHEMICAL SAFETY) in the Environmental Health Criteria (EHC) series in 1996. The limit for HCB in the FAO specification in 1998 for chlorothalonil was 0.3 g/kg and manufacturer stated in that report that the company had improved the manufacturing process (see FAO Specification, 2015, p. 51).+Before 2006 there was no legal regulation in Germany on the maximum content of HCB in the active substance chlorothalonil.

- +According to the BVL, no maximum permitted HCB concentrations have ever been legally established for the technical active substances atrazine, simazine, lindane and clopyralid, nor are such limits in place today. Further information on the sales volumes of atrazine, simazine and cloparylide is now available but not included in the current submission. The method will be reviewed accordingly, adjusted and extended for the 2023 submission.
