Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.

Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

Environmental pollutants like polychlorinated biphenyls are highly stable and resist degradation, persisting in our surroundings for prolonged periods. These chemicals infiltrate our bodies through bioaccumulation in the food chain followed by human consumption, causing dermatological and hepatic complications.

Agricultural chemicals, especially organochlorine pesticides, are persistent and prone to bioaccumulation, particularly within aquatic ecosystems. Long-term animal testing studies revealed their potential to promote oncogenesis. Due to their lipid solubility, organic solvents, such as halogenated hydrocarbons, can cross the blood-brain barrier, leading to central nervous system depression. Chronic occupational exposure to these substances has been associated with various types of cancer.

Lastly, heavy metals found in paint, food, and drinking water can cause poisoning that impacts the central nervous system and other organs, illustrating the pervasive risk of toxic chemical exposure in our daily environment.
