Determination and seasonal analysis of physicochemical characterization and metal(oid)s of landfill leachate in Bushehr port along the Persian Gulf

This study focused on the investigation of physicochemical characterization and metal(oid)s in landfill leachate of Bushehr port along the Persian Gulf. TDS, BOD5, COD, Hg, and Cd concentrations in fresh leachate were above leachate discharge standards. Significant differences were detected among alkalinity, EC, COD, and Na+ levels in various seasons. Furthermore, the high leachate pollution index (LPI) value showed a significant amount of pollutants present in landfill leachate. The results of this study help in understanding the pollution potential of landfill leachate of Bushehr port along the Persian Gulf. Thus, decision-makers should manage landfill leachate to reduce further environmental pollution.

Automated summary

This study investigated the physicochemical characterization and metal(oid)s in landfill leachate of Bushehr port along the Persian Gulf. The results showed a significant amount of pollutants in the leachate, with significant differences among seasons. Therefore, managing leachate is necessary to reduce environmental pollution.
