Raw data of watchlist substances analysed in surface water in Luxembourg

Analysis of watchlist substances in surface waters are carried out at a frequency of 4 times per year at two representatif surveillance stations in Luxembourg. The chemicals included in the watchlist are determined on a EU level and include chemicals that potentially pose a significant risk to the aquatic environment but for which insufficient data exist to determine the actual risk posed by these substances. The first watchlist (EU 2015/495; https://eur-lex.europa.eu/eli/dec_impl/2015/495/oj) was analysed from January 2016 until April 2018. The second watchlist (EU 2018/840; https://eur-lex.europa.eu/eli/dec_impl/2018/840/oj) was analysed from July 2018 until January 2021. The third watchlist (EU 2020/1161; https://eur-lex.europa.eu/eli/dec_impl/2020/1161/oj) was analysed from March 2021 until October 2022. The analysis for the fourth watchlist (EU 2022/1307; https://eur-lex.europa.eu/eli/dec_impl/2022/1307/oj) started in January 2023 and is still ongoing.

在卢森堡，针对地表水体中的监控清单物质的分析以每年四次频率进行，此分析在两个具有代表性的监测站展开。监控清单中的化学物质由欧盟层面确定，包括可能对水生环境构成重大风险，但缺乏足够数据以确定这些物质实际风险等级的化学物质。首个监控清单（EU 2015/495；https://eur-lex.europa.eu/eli/dec_impl/2015/495/oj）的分析自2016年1月至2018年4月进行。第二个监控清单（EU 2018/840；https://eur-lex.europa.eu/eli/dec_impl/2018/840/oj）的分析自2018年7月至2021年1月进行。第三个监控清单（EU 2020/1161；https://eur-lex.europa.eu/eli/dec_impl/2020/1161/oj）的分析自2021年3月至2022年10月进行。第四个监控清单（EU 2022/1307；https://eur-lex.europa.eu/eli/dec_impl/2022/1307/oj）的分析自2023年1月启动，并持续进行中。
