 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 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.

-According to information from the BVL (October 2020, personal communication), the maximum content of HCB in chlorothalonil was increased from 10 to 40 mg/kg in the products "AMISTAR Opti" (005748-00/00) and "CREDO" (006542-00/00) 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 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.

 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. Due to the revised data, changes in HCB quantities occur. 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. Due to the revised data, changes in HCB quantities occur.
-The maximum HCB quantity for picloram, in the period under consideration, were lower, respectively, than the relevant quantities for chlorothalonil. For this reason, fluctuations in sales of picloram have very little impact on maximum HCB quantities.+The maximum HCB quantity for picloram, in the period under consideration, were lower, respectively, than the relevant quantities for chlorothalonil. For this reason, fluctuations in sales of picloram have very little impact on maximum HCB quantities.The maximum HCB quantities used in the 2022 submission correspond to the emissions and are presented under the chapter 'Recalculations'.

-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). Abgerufen am September 2021, von https://www.bvl.bund.de/SharedDocs/Fachmeldungen/04_pflanzenschutzmittel/2019/2019_06_19_Fa_Widerruf_Chlorthalonil.html)). 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. According to the Implementing Regulation (EU) 2019/677 ((Regulation (EU) 2019/677: Commission Implementing Regulation (EU) 2019/677 of 29 April 2019 concerning the non-renewal of the approval of the active substance chlorothalonil, in accordance with Regulation (EC) No 1107/2009 of the European Parliament and of the Council concerning the placing of plant protection products on the market, and amending Commission Implementing Regulation (EU) No 540/2011, http://data.europa.eu/eli/reg_impl/2019/677/oj)), the BVL revoked the last three approvals for plant protection products containing chlorothalonil as of 31 October 2019. There was a sales deadline of April 30, 2020 (see https://www.bvl.bund.de/SharedDocs/Fachmeldungen/04_pflanzenschutzmittel/2019/2019_06_19_Fa_Widerruf_Chlorthalonil.html of June 19, 2019).
