摘要：The hazard quotient (HQ), the ratio of the intake of the substance to its reference dose, is usually used in the health risk assessment (HRA) of a noncarcer substance.However, the values of HQ cannot inform any specific human health effect.Compared to HQ, using epidemiological studies in HRA can improve the defect.This study attempts to examine the potential of the use of epidemiological studies for HRA.Previous epidemiological studies help to construct the linear concentration-response relationships between air pollutants and associated diseases and two case studies are used to demonstrate this method.
