The field of risk assessment has focused on protecting the health of individual people mostly from chemical exposure. However, the vulnerability has received little specific attention in the risk assessment literature. A tentative comprehensive index for environmental health vulnerability which is the product of physical vulnerability index and social vulnerability index was proposed. Based on the experimental data of heavy metal pollution in soil and vegetables and the survey data of population and social, the physical vulnerability, social vulnerability and comprehensive environmental health vulnerability of the area were analyzed in Daye city, China. For physical vulnerability, the average physical vulnerability value of the population in the polluted area and the reference area were 3.99 and 1.00, respectively. Weiwang village has the highest physical vulnerability, reaching 8.55. Vegetable intake is the exposure that should be paid more attention, which contributes more than 90% to physical vulnerability among four exposure pathways. Arsenic and cadmium should be the priority pollutants with the average physical vulnerability value contribution of 63.9% and 17.0%, respectively. According to social vulnerability assessment, Luoqiao village has the highest social vulnerability, with a value of 0.77. For comprehensive environmental health vulnerability, 5 villages nearby mining activities and 2 villages far from the mine-affected area have a high physical vulnerability and high social vulnerability, which are the urgent areas in environmental risk management. In order to carry out environmental risk management better, it is necessary to give priority to identifying and controlling pollution areas and pollutants and effectively identify vulnerable populations.
