摘要

In this research, 222Rn, 226Ra and heavy metal concentrations in water samples collected from key stages of a textile manufacturing plant were measured to assess their transfer into wastewater and potential environmental impact. Results showed that the discharged effluent contained radon and radium levels below international recommended thresholds for drinking water. Heavy metal concentrations remained within regulatory limits, except for elevated Cr at the dye house outlet in winter, likely due to seasonal pigment use. Risk assessments indicated low ecological risk in both sampling seasons. Findings suggest current treatment processes effectively mitigate radiological and heavy metal contamination in textile effluents.
