HVD - Annex 2 Earth Observation and Environment - Water - Raw data of substances analysed in surface water suspended solids in Luxembourg - 4th Watchlist (LU–SW–WL) (2022)

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 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.
