Step-by-step explanation:
The potentially harmful chemicals released by factories, farms, and cars that can enter the food supply are known as chemical contaminants. These contaminants can include toxic chemicals such as pesticides, persistent organic pollutants (POPs), radioactive materials, and heavy metals.
