Abstract

In order to clarify the selenium nutritional status of the population from different selenium levels, 76local residents (exposed population) and 116foreign tourists from Suzhou, Wuxi, Changzhou and Shanghai (control population) were recruited to participate in a questionnaire survey in Wentang Town to collect their basic information, living habits, dietary frequency, etc. The selenium content of the soil, water, atmospheric particulate matter and food samples from Wentang and Linhu Towns was analyzed according to the classical health risk assessment method of the U.S. Environmental Protection Agency (USEPA). The selenium exposure levels, exposure pathways and health risks were analyzed according to the classic four-step health risk assessment method of the U.S. Environmental Protection Agency (EPA). The average daily dietary selenium intake of local residents was significantly higher than that of foreign tourists, and the highest contributors to the dietary selenium intake of the residents in both areas were eggs and livestock and poultry meat. The average selenium exposure of local residents was also significantly higher than that of foreign tourists, with diet being the main exposure route. In this study, the average daily selenium intake of the residents living in Wentang met the standard, and there was no non-cancer risk due to excessive selenium intake, while 88.76% of the foreign tourists had insufficient selenium intake, which suggests that the residents living in non-selenium-rich areas need to improve selenium intake by adjusting the dietary structure and the source of the diet.
