The potentially toxic elements (PTEs), Cu, Pb, Zn, Cd, Cr, Hg and As in the water from the Beibu Gulf, were investigated to reveal the contaminant characteristics and assess the risks to human health. The results showed that the concentration of PTEs in the Beibu Gulf varies significantly both seasonally and spatially, with higher concentrations in summer and in the northern and southern gulf. Terrestrial inputs and local anthropogenic discharge are responsible for the higher level in the northern gulf, and the transportation of water masses is also an important factor for the higher concentrations in the southern gulf. Ecological risk assessment suggested that Hg is the main ecological risk factor. The health risk assessment revealed that dermal exposure to PTEs in the gulf presents potentially carcinogenic health effects for humans. This study provides new insight into the transport of PTEs over a large area of the Beibu Gulf.
北部湾海水中的潜在有毒元素（PTEs）Cu、Pb、Zn、Cd、Cr、Hg 和 As 进行了调查，以揭示污染物特征并评估对人类健康的风险。结果表明，PTEs 的浓度在北部湾具有明显的季节性和空间变化，夏季和北部和南部海湾的浓度较高。陆地输入和当地人为排放是北部海湾浓度较高的原因，水体的输送也是南部海湾浓度较高的重要因素。生态风险评估表明，Hg 是主要的生态风险因素。健康风险评估表明，人类通过皮肤接触海湾中的 PTEs 可能具有致癌的健康影响。本研究为了解北部湾大面积地区 PTEs 的迁移提供了新的见解。
