Results from the polling of workshop participants in relation to an appropriate health-based threshold level that the California State Water Resources Control Board should adopt for MPs in drinking water. Results presented are based on the experts’ qualitative judgement of the evidence of health effects obtained from the studies evaluated through the Tiered approach presented in this study. The box and whiskers plot represents the summary of votes (n = 9), with the upper and lower boundaries of the box indicating the 75th and 25th percentiles, respectively.
