  Water Pollution Water pollution occurs when harmful substances and contaminants are discharged into water bodies, such as rivers, lakes, oceans and groundwater, degrading the quality of water or contaminate it and harming aquatic life. It affects aquatic life, disrupts ecosystems and lead to waterborne diseases in humans. Major Pollutants: Heavy metals like lead and mercury Nutrients such as nitrates and phosphates Pathogens like bacteria and viruses Chemical contaminants from industrial processes Causes of Water Pollution Industrial Discharges:  Factories release harmful chemicals, heavy metals and toxic substances into water bodies. Effect: Contamination of water, harming aquatic life and making water unsafe for human use. Agricultural Runoff:  Excessive use of fertilizers, pesticides and animal waste washes into rivers and lakes. Effect: Eutrophication, leading to algal blooms and depletion of oxygen in water. Sewage and Waste water:  Untreated or partially trea...

Air Pollution: Causes, Effects and Measures Air pollution occurs when harmful substances, including gases, particulates (solid light particle for e.g. fly ash) and biological particles, are introduced into the Earth's atmosphere (air, space). This type of pollution can have severe consequences for both the environment and human health. These pollutants can cause respiratory diseases, cardiovascular problems and environmental damage . Understanding its causes, effects and measures to mitigate it is crucial for fostering a healthier environment. Air pollution arises from both natural and human-made sources ( causes). 1.    Industrial Emissions : Factories and power plants release pollutants such as sulfur dioxide (SO2), nitrogen oxides (NOx) and particulate matter (PM) into the air. 2.   Vehicle Emissions : Cars, trucks and other vehicles emit carbon monoxide (CO), hydrocarbons and NOx, which contribute significantly to urban air pollution. 3.   Burning of Fo...

  Environmental Pollution Pollution Pollution is the introduction of harmful substances or pollutants or contaminants into the environment, causing damage to air, water, land or living organisms. It disturbs composition of natural resource. Pollution is occurred due to natural events or human activities and negatively impacts ecosystems and human health. It is classified into several types based on the medium (air, water and soil) it affects. There are main two types of pollution such as primary pollution and secondary pollution: Primary pollution include air pollution; water pollution and land pollution can be described as follows. Types of Pollution 1. Air Pollution Air pollution occurs when harmful substances, including gases, particulates (solid light particle for e.g. fly ash) and biological particles, are introduced into the Earth's atmosphere (air, space). This type of pollution can have severe consequences for both the environment and human health. These pollutan...
