Studies on emerging chemical risks on Living beings in a chemical world

Emerging chemical risks may arise from intentional or unintentional contamination of the food chain either by anthropogenic or ‘natural’ chemicals. More than 160 million chemicals are known to humans. About 40 000 to 60 000 of them can be found in commerce; 6000 of these account for more than 99% of the total volume of chemicals in commerce globally. Chemicals, whether of natural origin or produced by human activities, are part of our environment. Manufactured chemicals include industrial and agricultural products such as pesticides, petroleum products and processed metals. Some chemicals are manufactured for specific uses, while others are unwanted by-products, including wastes, or products of combustion such as toxic gases and particles from industrial emissions and burning of fuel. Emerging chemical risks are new or unforeseen chemicals that may pose a threat to human, animal, or plant health. These chemicals can be synthetic and may alter a living being's metabolism. They can enter the body through consumer products, food, or the environment. The review of this manuscript is reveals that the Exposure to chemicals can have a wide range of health effects.
