摘要

Objective

The study aimed to assess the contamination levels of heavy metals and physicochemical parameters in textile wastewater and evaluate their potential environmental and health risks.

Methods

Twenty-six wastewater samples were collected from various textile mills using plastic bottles. The samples were preserved in iceboxes to maintain their characteristics and analyzed in the laboratory for pH, electrical conductivity (EC), biological oxygen demand (BOD), dissolved oxygen (DO), and concentrations of heavy metals such as chromium (Cr), copper (Cu), and cadmium (Cd).

Results

The analysis revealed that all samples had elevated pH, EC, and BOD levels, with reduced DO levels. Heavy metals Cr and Cu were present at concentrations exceeding permissible limits, while Cd remained within acceptable levels. The highest Cr concentration (1.72 mg L−1) was recorded in effluent from the Dawood Textile Industry, which also showed higher values for other pollutants.

Conclusion

Textile effluents contain significant levels of pollutants, including heavy metals, posing threats to environmental, human, and ecological health. Proper treatment of wastewater before disposal is crucial to minimize these adverse impacts.
