ABSTRACT
Environmental pollutants have a significant impact on the ecosystem and disrupt balance between environment, human and non-human components that result in deleterious effects to all forms of life. Identifying environmental factors for potential imbalance are extremely crucial for devising strategies for combating such toxic dysregulation. Automobile exhaust (in air), heavy metals (in food and water) and pesticides (in air, food, soil and water) are the most common environmental pollutants and their short and long term exposures can cause hazardous effects in humans leading to systemic disorders involving lungs, kidney and immune systems. Mechanisms involved in genesis of such toxic effects have revealed complex, interactive pathways. Strategies for the protection of homeostasis and health, viz., general preventive measures, nutritional supplements and herbal agents have been described, to counter these pollutants induced damaging effects on various body systems.
