It is important to determine the impact of urbanization on health risk substances in rivers for healthy city management and watershed pollution control. With lead and mercury as the typical health risk substances, Haihe River Basin, which was characterized by rapid urban development, was selected as the study area. Factor analysis and multiple regression analysis were used to establish the response relationship between the pollution load of the monitoring section and the intensity of human activities within the control basin. The results showed that human activities in the basin could be divided into urban, rural, natural and other factors. Lead and mercury loads in the river were significantly correlated with urban factors, but not with rural, natural and other factors. In the process of urban development, it is necessary to pay more attention to health risk substances such as lead and mercury, strengthen relevant control measures, and effectively support the management of healthy cities.
