Abstract Objective: To determine the levels of environmental estrogens (ESs) in foods in Wenzhou, and perform an assessment of the health risk of ESs. Methods: Randomly selected items from categories of meat, fish/shellfish products, vegetables and cereals of the city and the concentration of ESs, such as nonylphenol (NP), bisphenol A (BPA), ethinylestradiol (EE2) and estradiol (E2), were determined by LC-MS/MS. Daily dietary exposure and health risk index of each estrogen were calculated considering the dietary pattern of the local people. Results: ESs were detected in all samples, the highest detection rate was of NP (100%) while the lowest was of EE2 (49.3%). Four ESs were simultaneously detected in about 1/4 of the samples and two or more ESs were detected in 96.6% of foods. The average dietary exposure risk index of NP, EE2, and BPA were 1.09×10-2, 0.41, and 1.84×10-4 and the maximum dietary exposure risk index of NP, EE2, and BPA were 2.88×10-2, 1.20, and 8.85×10-4, respectively. Conclusion: Four ESs are detected in almost every food samples; The health risk index of NP, E2 and BPA is less than 1 in food samples in Wenzhou. But the exposure level of E2 may have risk to local residents.
