Addressing the objective on characterization of exposure pathways and estimation of exposure concentrations of chemical contaminants in the food chain both Alsafran et al. explored the cadmium bioaccumulation in wheat looking at the tolerance levels in two different cultivars and found that the tolerant variety not only have better survival and adaptability under cadmium stress but also accumulate more macro- and micro-nutrients in the grains resulting in lowering of health hazards when consumed by the people. We would extend our sincere thanks to the Editor-in-chief and other editorial board members of the Frontiers in Environmental Science for providing us the opportunity to assemble this Research topic on Exposure Pathways, Characterization and Risk Assessment of Chemical Contaminants in the Food Chain. The third part looks at where people could come in contact with the chemical. Total Environ. The editor and reviewer's affiliations are the latest provided on their Loop research profiles and may not reflect their situation at the time of review. With increasing global food demand, it is an important responsibility of all producers, distributors, consumers, and regulators to ensure food safety. There are five parts of the exposure pathway and each is evaluated to determine if people could be exposed to site-related contamination. Some examples of this include outdoor or indoor air, drinking water taps, residential yards, where the chemical was spilled, and the food supply. Furthermore, toxin accumulation potential of food crops depends on other factors. For example, if someone uses a public water supply, they would not be exposed to any contaminated groundwater from an old well that is on their property but that no one uses.

The first part identifies a contaminant source or a place where the chemical was released. B., Rahman, M. A., et al. Front. Considering the importance of translation of the current knowledge on exposure to a chemical contaminant in food into basic principles for regulatory control, the meta-analysis by Mandal et al. Similarly, De et al. Both inorganic and organic pollutants enter the food chain due to various reasons including human led contamination of naturally occurring elements, like the presence of arsenic in soil and irrigation water resulting in accumulation in crops, and anthropogenic contamination, like pesticide or rodenticide accumulation in crops due to its widespread use. Environ. *Correspondence: Debapriya Mondal, dmondal@sgul.ac.uk; Mohammad Mahmudur Rahman, mahmud.rahman@newcastle.edu.au, Exposure Pathways, Characterization and Risk Assessment of Chemical Contaminants in the Food Chain, View all The next part looks at how the chemical might move or change in the environment. The fifth and final part in the exposure pathway evaluates whether there are people in the community who could be exposed. Hence, most of the studies illustrated innovative methods and techniques for human health risk estimations. No use, distribution or reproduction is permitted which does not comply with these terms. One of the biggest threats to the safety of our food is the unintentional and undesirable presence of chemical contaminants. investigated fluoride exposure in endemic areas of West Bengal, India and have found higher contribution from vegetables compared to cereals. Air, soil, and water are the major elements that can move or change a chemical. Sci. 703, 134774. doi:10.1016/j.scitotenv.2019.134774, Keywords: food contamination, health risk assessment, contaminants, exposure pathway, risk assessement, Citation: Mondal D and Rahman MM (2022) Editorial: Exposure Pathways, Characterization and Risk Assessment of Chemical Contaminants in the Food Chain. Anthropogenic activities have led to the increase in environmental contaminants. For example, Halim et al. Sci. Wheat is an Amerging Exposure Foute for Arsenic in Bihar, India. Total Environ. Apart from contamination during primary production, contaminates can also enter the food chain during storage, transportation, handling, and most importantly during cooking and processing. (2021). Cultivated in Qatar and specific area of India respectively, both studies have indicated significant accumulation of certain metals like vanadium, chromium, arsenic, cadmium, and lead in rocca, coriander, and parsley in Qatar and zinc and manganese in coriander in India indicating health risks. (2020). Thus, understanding the impact of contaminants exposure from food components, is crucial and research on reducing exposure from food is vital.
