Unveiling water quality and health risks from groundwater chemicals in Poyang Lake basin of China: a sophisticated analysis.

ABSTRACT:

Background

Groundwater is a critical water resource in the Poyang Lake basin, especially given the increasing frequency of extreme drought events. However, comprehensive assessments of its chemical characteristics and associated health risks remain insufficient. This study aims to provide a comprehensive assessment of groundwater quality and associated health risks in the Poyang Lake basin, China.

Methods

This study collected 670 groundwater samples from domestic and agricultural wells across the basin during the 2022 dry season. Hydrochemical parameters, including manganese (Mn), ammonia nitrogen (NH_4⁺ ), iron (Fe³⁺), aluminum (Al³⁺), chemical oxygen demand (COD), fluoride (F^-), and nitrate (NO_3^- )
