The major effects of Water Pollution are as follows: Water Pollution affects both animals and plants and leads to an adverse impact on the aquatic ecosystem. Inappropriate disposal of litter such as plastic bags, wrappers and bottles, lead to Water Pollution.Oil spills that are an accidental release of oil by tankers in oceans may cause marine water pollution.Discharge of toxic waste from factories and refineries.Excessive use of fertilisers and pesticides in agriculture also causes water pollution.Discharge of untreated domestic sewage into rivers leads to water pollution.Let us look at the sources of water pollution in the section below: Due to human activities, ponds, rivers, oceans, and estuaries are getting polluted in several parts of the world. Water Pollution is defined as any undesirable change in physical, chemical, or biological properties of water that may affect living beings adversely. Particulate and gaseous air pollutants released by various industries.Smokestacks of thermal power plants, smelters, etc.Excessive use of fossil fuels by automobiles.The major causes of air pollution are as follows: Fluoride is another pollutant, which causes fluorosis among animals. Among metallic contaminants, arsenic, lead, and molybdenum are harmful to animals.Chronic poisoning results from the ingestion of forage contaminated with atmospheric pollutants. The negative impact of air pollution on animals is more or less similar to that on humans.Causes immediate effects like inflammation, nausea, headache, and irritation to the eyes and nose.Causes cardiovascular diseases and damage to the central nervous system, resulting in premature death.Causes respiratory ailments like asthma, hay fever, and other allergic diseases.Causes an increase in susceptibility to diseases.About \(\) of human deaths occur due to air pollution.It leads to the production of free radicals, thus, decreasing photosynthesis and productivity. Acid rain damages the aerial parts and also acidifies the soils.Weakens plants and increases infestation by pests.Decreases the growth yield of crops and causes premature death of plants.It causes fruit damage and various leaf diseases like chlorosis, necrosis, and mottled spots on leaves.The various effects of air pollutants on plants, animals, and humans are as follows: Now let us check out the effects of pollution on the environment in the below-mentioned section: Effects of Air Pollution Gaseous pollutants in the air constitute carbon dioxide, nitrogen dioxide, hydrogen sulphide, and sulphur dioxide. Particulate pollutants which constitute metallic particles, dust particles, soot, aerosol, and smoke.Ģ. Harmful effects caused by air pollution depend on the following:Ĭheck out the causes of environmental pollution in the below-mentioned section:ġ. Types of Environmental Pollutionīased on the part of the environment that is polluted, Pollution is of the following types:Īir Pollution occurs due to undesirable changes in the physical, chemical, or biological characteristics of air that exert harmful effects on all living beings. Water Pollution is caused by many substances, such as those found in fertilisers and industrial effluents. Atmospheric Pollution is caused by gases such as sulphur dioxide, carbon monoxide, and nitrogen oxides being released into the atmosphere by various industries and by burning fossil fuels. Modifying the environment caused by human influence, which often renders the environment harmful and unpleasant to live in, is called Pollution. Slowly degradable pollutants remain in the environment unchanged for many decades. Pollutants can be degradable, like discarded vegetables rapidly broken down by the natural process. So, even a tiny amount of pollutants in the air becomes significant compared to similar levels in food. Pollutants can be solid, liquid, or gaseous substances present in greater concentrations than in natural abundance and may produce due to human activities or natural happenings.įor example, an average human being requires around 12−15 times more air than food. A substance that causes Pollution is known as a Pollutant. Environmental Pollution Definition: Types of Environmental PollutionĮnvironmental Pollution is the effect caused by undesirable changes in our surroundings that have harmful impacts on plants, animals, and human beings.
