Abstract
Food safety is an important factor affecting people’s health and quality of life. As a key means ensuring food safety, the chemical pollution assessment of food has also become the research focus in the current food safety field. In recent years, all countries in the world have paid more attention to food safety, and China is no exception. Taking Daxing District of Beijing as the research object, this paper conducts the risk assessment of chemical pollution in organic foods. According to the research results, through detecting metal contaminants (lead, cadmium, mercury), organophosphorus pesticides, and food additives etc. of the selected organic foods, it’s found that the heavy metal pollution in organic foods was not serious, and all the detection results of organophosphorus pesticides were below the minimum detection limit and the content of food additives did not exceed the national standard. The single-factor pollution index indicates that organic foods have a low degree of pollution, and the comprehensive pollution index indicate that all organic foods are safe and clean except that the comprehensive pollution index of cucumbers shows mild pollution.
