Description
|
This dataset contains ecotoxicological endpoints and derived predicted no-effect concentrations (PNECs) for five organic UV-filters (avobenzone, octocrylene, octinoxate, iscotrizinol, and ethylhexyl triazone) used in the environmental risk assessment of Lake Balaton (Hungary).
The dataset includes acute EC₅₀ and, where available, chronic NOEC values for freshwater organisms, primarily Daphnia magna. PNECs were derived in accordance with the Technical Guidance Document on Risk Assessment (European Commission, 2003) using compound-specific assessment factors (AFs). For compounds with chronic toxicity data available, PNECs were based on the most sensitive endpoint; otherwise, acute EC₅₀ values were used with appropriate AFs.
These data form the toxicological basis for risk quotient (RQ) calculations and mixture toxicity assessment (TU_mix) applied to measured environmental concentrations in surface waters of a large shallow freshwater recreational ecosystem. |
