Exceedance Probability and Toxicity-Value Sensitivity in Health-Risk Assessment of a Pb–Zn Slag Reprocessing Site Under the 2025 IRIS Arsenic Values
Screening-level risk assessments report single-point estimates of carcinogenic risk (CR) and hazard index (HI), conveying neither the probability of exceedance nor its sensitivity to revised toxicity values. We examined both at an active lead–zinc slag reprocessing site in Shymkent, Kazakhstan, by reanalysing a publish...
