KNIHY "Pesticides used in agro-ecosystems and forests enter aquatic environments such as streams, rivers, and lakes if applied in adjacent areas or if an accidental spill occurs. For the studies, we chose the early life stages of common carp (Cyprinus carpio L.) and marbled crayfish (Procambarus fallax f. virginalis). In selected organisms, we observed long-term effect of triazine herbicides (prometryne, terbuthylazine, metribuzine) and their metabolites (terbuthylazine-desethyl and tebuthylazine-2-hydroxy) in concentrations commonly occurring in Czech rivers. The first part is about monitoring the effects of triazines (prometryne, terbuthylazine) on the early development stages of carp and marble crayfish. Subchronic prometryne exposure of early-life stages of common carp at concentrations of 1 200 and 4 000 ?g/L affected their survival, growth rate, early ontogeny, and histology. Terbuthylazine in concentration 1 400 and 3 000 ?g/L caused significant decrease of mass, total length, delayed in development and cause of alternation of tubular system of caudal kidney of carp. Prometryne in concentration 144, 1 444 and 4 320 ?g/L caused decrease of weight, specific growth rates and caused histopathological changes in gill of crayfish. Moreover concentration 4 320 ?g/L of prometryne caused delay in ontogenetic development of crayfish. Second part of the work has included effects of low concentrations of metabolites (terbuthylazine-desethyl and tebuthylazine-2-hydroxy) on the early development stages of carp and marble crayfish. Chronic terbuthylazine-desethyl exposure in concentrations 180, 900, and 1 800 ?g/L affected growth, ontogenetic development, and the antioxidant system and caused pathological changes in the caudal kidney of early life stages of carp. Chronic terbuthylazine-2-hydroxy exposure in concentrations 2.9, 70, 1 400 and 3 500 ?g/L caused decreased of total superoxide dismutase activity of early life stages of carp. Moreover concentration 1 400 and 3 500 ?g/L of terbuthylazine-2-hydroxy caused delay in ontogenetic development and pathological changes in the caudal kidney of carp. Chronic terbuthylazine-2-hydroxy exposure in concentrations up 75 ?g/l affected growth, ontogenetic development, antioxidant system, caused oxidative stress and pathological changes in hepatopancreas of early life stages of marbled crayfish. The last part of our study examined the effect of metribuzine on signal crayfish (Pacifastacus leniusculus Dana). Crayfish were exposed to metribuzine concentrations of 0.52 ?g/L and 3.06 mg/L for 30 days and a 30-day depuration period. In the thiobarbituric acid reactive substances, superoxide dismutase, and catalase were observed differences in all examined tissues (gill, muscle, hepatopancreas) compared to the control group. Differences from control were observed in glutathione reductase activity in hepatopancreas after 10 days for both exposure concentrations and after 30 days at 3.06 mg/L. Histological examination revealed extensive focal autolytic disintegration of tubular epithelium in hepatopancreas of crayfish exposed to metribuzin. These studies provided important results for the evaluation of long-term impact and effect of (prometryne, terbuthylazine and metribuzine) and their metabolites (terbuthylazine-desethyl and tebuthylazine-2-hydroxy) on the water non-target organisms, even in real concentrations founded in surface waters."
