Herbicides in the cave environment: Ecotoxicological risks

Original language description

This study aimed to detect triazine pesticides and their metabolites in the drip water of the Amaterska cave system (Moravian karst, Czech Republic). Ecotoxicological tests were used to assess the risk of selected herbicides (i.e. atrazine and terbuthylazine) and their metabolites (atrazinedesethyl, atrazine-desisopropyl, terbuthylazinedesethyl) in the drip water by means of bioassays with selected bioindicators. Tests were conducted on organisms representing all trophic levels of the aquatic ecosystem: producer algae Pseudokirchneriella subcapitata and macrophyte duckweed Lemna minor, a consumer water flea Daphnia magna, and decomposer bacterium Vibrio fischeri. Effects of herbicides on edaphon representatives were measured by testing the reproductive inhibition of enchytraeids Enchytraeus crypticus. Triazines and their metabolites were analysed in the drip water of the Amaterska cave system sampled at a site under agricultural cropland. Standard methods were used for testing procedures: OECD 201 (Freshwater algal growth inhibition test), OECD 221 (Lemna sp. Growth Inhibition Test), OECD 202 (Inhibition of the mobility of Daphnia magna), ISO 11348-2 (Inhibitory effect of water samples on the light emission of Vibrio fischeri) and OECD 220 (Enchytraeid Reproduction Test). Drip water samples were examined for 350 substances. Six pesticides above the limit of quantification were identified; all of these substances belong to the triazine pesticide group. The performed experiments showed no evidence of acute toxicity of the drip water. However, accumulation in the environment and chronic toxicity could not be ruled out. The ecotoxicity of selected herbicides and their metabolites differed significantly depending on the test organism and testing conditions.
