Due to a review by the FAO 288/2005 (see FAO 2015, p.22 and p. 51) and taking into account the results of batch samples testing the impurity the max. concentration was raised again up to 0.04 g/kg.

-For the years as of 2000, the specified maximum HCB concentrations in chlorothalonil differ considerably from pesticide to pesticide – in some cases despite the EU-regulation, the values differ from year to year for the same pesticide. For the year 2000 an interim value was calulated by linear interpolation. (170 mg/kg).

For the year 2000 an interim value was calulated by linear interpolation. (170 mg/kg). 
  
-The quantities of pesticide active substances sold, and reported pursuant to Art. 64 Plant Protection Act were used as a basis for deriving a weighted average for the maximum concentrations for 2000, 2005, 2010 and 2013 (cf. Table IV, concentrations of impurities). The average was used to calculate the relevant HCB quantities for the period between 2005 and 2008. For the later years starting from 2009 onwards the information on the maximum concentration of 10 mg/kg is assumed which is indicated by the authorisation holders (Syngenta Agro, 2015). For 2019, the same quantity is assumed as for 2018. The data will be updated with submission 2022.+According to information from the BVL (October 2021, personal communication), the maximum content of HCB in chlorothalonil was increased from 10 to 40 mg/kg in the products "AMISTAR Opti" and "CREDO" due to subsequently applied for active substance sources.  Likewise, an additional potential active substance source (production site) was also reported retroactively. For the years 2001 to 2017, the value of 40 mg/kg (for the reporting 2022) is used for the maximum content of HCB. 
 +For the years from 2018 onwards, the information from the authorisation holders (Syngenta Agro, 2015) is used for the maximum concentration of 10 mg/kg, as only the product “AMISTAR Opti” was still on the market.

-For picloram, a maximum concentration of 50 mg/kg has been specified for some pesticides. Relevant pesticides were introduced in Germany beginning in 2006. Picloram was added to Annex I with the Commission Directive 2008/69/EC ((Directive 2008/69/EC: Commission Directive 2008/69/EC of 1 July 2008 amending Council Directive 91/414/EEC to include clofentezine, dicamba, difenoconazole, diflubenzuron, imazaquin, lenacil, oxadiazon, picloram and pyriproxyfen as active substances 2008/69/EC C.F.R.

 === Lindane === === Lindane ===
  
  
-The HCB quantities in lindane were determined with the help of historically reported lindane-quantity data (cf. Table III) of the former former Federal Biological Office for Agriculture and Forestry (Biologische Bundesanstalt für Land- und Forstwirtschaft; BBA), Institute of Pesticide Technology Assessment (Institut für Folgenabschätzungen im Pflanzenschutz, Kleinmachnow). Those data are based on information that producers provided voluntarily. For the years after 1997 no data are available because the application of Lindan was phased out in 1998.+The data on lindane sales were compared by the BVL with historical data from the GDR statistics and published since 2020 (see Table II).

For the years after 1994 a lower concentration (50 mg/kg) was assumed which is based on compiled information of Bailey (2001)((Bailey, R. E., (2001): Global hexachlorobenzene emissions.

 While this results from the large quantities of chlorothalonil-containing pesticides sold, it is also due to the high chlorothalonil concentrations in such pesticides and to the high permitted maximum HCB concentrations (0.3 g/kg), in chlorothalonil as a technical active substance, that applied prior to 2000.

-The following chart give an overview of the emission trend of HCB (see Picture 1). The HCB emissions were calculated and updated for the years 2017 and 2018. The value for 2019 was updated. HCB emissions are mainly dominated by the proportion of chlorothalonil. +The following chart give an overview of the emission trend of HCB (see Picture 1). HCB emissions were fully recalculated up to 1990. HCB emissions are mainly dominated by the share of chlorothalonil. According to the BVL (2021a), a possible explanation for the increase in HCB emissions from 2005 onwards would be the re-approval of "Bravo 500" in December 2004 against Septoria in wheat and then for the first time against Phytophthora in potatoes. 
-According to the information of the BVL, a possible explanation for the increase of HCB emissions from 2005 onwards would be the renewed approval of Bravo 500. Possibly the first "sell-out" took place in 2014, because the approval end of "Bravo 500" was originally 30.04.2016 with a sales period until 30.10.2016 and a use-by period for users until 30.10.2017.+It is possible that the first "sell-out" took place in 2014, as the end of approval for "Bravo 500" was originally 30.04.2016 with a sales deadline of 30.10.2016 and a phase-out period for users until 30.10.2017. 
 +The end of the EU active substance authorisation for chlorothalonil was later extended to 31.10.2018 and again to 31.10.2019, and with it the authorisations for the plant protection products in Germany. With the Implementing Regulation (EU) 2019/677 23), the BVL revoked the last three approvals for plant protection products containing chlorothalonil on 31 October 2019((cf. BVL; 2019: BVL - Fachmeldungen - Widerruf der Zulassung von Pflanzenschutzmitteln mit dem Wirkstoff Chlorthalonil zum 31. Oktober 2019. (2019, 31. Oktober).

A sell-off period until 30 April 2020 applied. Often, in the last years before the end of the approval, the remaining stocks are brought onto the market, which leads to higher sales than in previous years.
  
-The end of the EU active substance approval for chlorothalonil was later extended to 31.10.2018 and again to 31.10.2019, and accordingly also the approvals for the pesticides in Germany.
