 For lindane, a maximum concentration of 100 mg/kg was specified for the years 1990 through 1994. 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. Chemosphere, 43(2), 167-182.)) (cf. Table III). For lindane, a maximum concentration of 100 mg/kg was specified for the years 1990 through 1994.

-HCB emissions are mainly dominated by the share of chlorothalonil. According to the BVL (2021a) ((BVL (201921a) (Bundesamts für Verbraucherschutz und Lebensmittelsicherheit Braunschweig): persönliche Mitteilung der Wirkstoffdaten, 2021)), 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.+HCB emissions are mainly dominated by the share of chlorothalonil.

 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. 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.

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.No active ingredient of chlorothalonil was sold in 2021. This means that chlorothalonil is off the market for the time being. Picloram has an approval end date of Dec. 2023. Picloram is thus also subject to a disposal obligation under Section 15 of the PflSchG because the plant protection products contain an active substance that is no longer approved in the EU.  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.

-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.+For the next submissions no further improvements are planned.
