摘要： The Internet has facilitated the sale of aquatic products on e-commerce platforms such as Taobao, Tmall, Jingdong, allowing people to meet their daily nutritional needs without leaving home. While e-commerce platforms have facilitated people's lives, they have also made the risk of food contamination difficult to control. Consequently, it is necessary to assess the risk of food sold by e-commerce. Trace elements contamination in aquatic food is a worldwide issue. In this study, an automated tool was written in Python to search 11,596 information about tilapia products sold on e-commerce platforms, and collect samples based on the above data. The content of trace elements in representative samples sold on these e-commerce platforms was quantitatively analyzed (n=147). The results indicate that over 90 % of the samples contained more than 9 trace elements. The levels of trace elements in canned tilapia were significantly higher than those in frozen and pickled tilapia (p<0.05). Based on target hazard factor assessment method, arsenic was found to have the highest potential dietary risk (THQ>1). Additionally, the risk of intake for children was found to be 2-3 times higher than that for adults. It is suggested that children limit their intake of canned tilapia, pickled tilapia, and frozen tilapia fillets to 0.05 kg/day, 0.17 kg/day, and 0.14 kg/day, respectively. The high detection frequency of trace elements provides a snapshot of the prevalence of trace elements in tilapia products sold on Chinese e-commerce platforms.
