What are the effects of water pollution on aquatic life?

What are the effects of water pollution on aquatic life?

Organic matter and nutrients causes an increase in aerobic algae and depletes oxygen from the water column. This causes the suffocation of fish and other aquatic organisms. Sulfate particles from acid rain can cause harm the health of marine life in the rivers and lakes it contaminates, and can result in mortality.

What is water pollution and its main harmful effects?

Domestic Sewage – Wastes generated from households are one of the major contributors to water pollution. The wastes which contain urine, feces, laundry waste lead to a lot of waterborne diseases such as cholera, dysentery, typhoid, and diarrhea.

Which of the following effect is the result of water pollution?

Effects of Pollution of Water It causes typhoid, cholera, hepatitis and various other diseases. Destruction of Ecosystems: Ecosystems are extremely dynamic and respond to even small changes in the environment.

What is the cause and effect of water pollution?

Humans are the main cause of water pollution, which is triggered in many ways: by the dumping of industrial waste; due to temperature rise, that cause the alteration of water by reducing the oxygen in its composition; Or due to deforestation, which causes sediments and bacteria to appear under the soil and therefore …

How do humans affect water pollution?

Agriculture is also the main source of pollution in rivers and streams in the U.S. One way that agriculture causes water pollution is through rainwater. When it rains, pollutants, such as fertilizers, animal waste, and pesticides get washed from farms into waterways, contaminating the water.

What is the main cause of water pollution?

Major sources of water pollution are discharge of domestic and agriculture wastes, population growth, excessive use of pesticides and fertilizers and urbanization. Bacterial, viral and parasitic diseases are spreading through polluted water and affecting human health.

Who is responsible for water pollution?

As amended in 1977 (P.L. 95-217), this law became commonly known as the Clean Water Act (CWA). The CWA is the principle law governing pollution control and water quality of the Nation’s waterways and is primarily overseen by the U.S. Coast Guard (USCG) and the Environmental Protection Agency (EPA).

What is the solution for water pollution?

DO NOT pour fat from cooking or any other type of fat, oil, or grease down the sink. Keep a “fat jar” under the sink to collect the fat and discard in the solid waste when full. DO NOT dispose of household chemicals or cleaning agents down the sink or toilet.

What are the effects of pollution?

Short term exposure to air pollution can irritate the eyes, nose and throat and cause upper respiratory infections, headaches, nausea and allergic reactions. Long-term exposures can lead to chronic respiratory disease, lung cancer, and heart disease.

What is Pollution its causes and effects?

High levels of air pollution can cause an increased risk of heart attack, wheezing, coughing, and breathing problems, and irritation of the eyes, nose, and throat. Air pollution can also cause worsening of existing heart problems, asthma, and other lung complications.

What are the effects of pollution on human health?

Exposure to high levels of air pollution can cause a variety of adverse health outcomes. It increases the risk of respiratory infections, heart disease and lung cancer. Both short and long term exposure to air pollutants have been associated with health impacts. More severe impacts affect people who are already ill.

What is the impact of pollution and air quality on the environment?

Air pollution can damage crops and trees in a variety of ways. Ground-level ozone can lead to reductions in agricultural crop and commercial forest yields, reduced growth and survivability of tree seedlings, and increased plant susceptibility to disease, pests and other environmental stresses (such as harsh weather).

What are the sources of particulate matter on environment?

Some are emitted directly from a source, such as construction sites, unpaved roads, fields, smokestacks or fires. Most particles form in the atmosphere as a result of complex reactions of chemicals such as sulfur dioxide and nitrogen oxides, which are pollutants emitted from power plants, industries and automobiles.

What are the environmental effects of particulate matter?

Environmental Impacts Of Particulate Pollution Particulate matter pollution contributes to acid rain and climate change. In addition to the worsening of acid rain, particulate pollution can also change weather patterns, cause drought, contribute to global warming, and cause the ocean to acidify.

What do particulates cause?

Particulates are the most harmful form of air pollution due to their ability to penetrate deep into the lungs, blood streams and brain, causing health problems including heart attacks, respiratory disease, and premature death.

What are examples of particulates?

Particulates, or particulate matter (PM), refer to any mixture of solid particles or liquid droplets that remain suspended in the atmosphere for appreciable time periods. Examples of particulates are dust and salt particles, and water and sulphuric acid droplets.

What type of ozone is good?

Stratospheric ozone

What are the top 3 sources of particulate matter in the atmosphere?

Natural sources of PM include sea salt, dust (airborne soil, also called crustal material), secondary sulphate, pollen, black carbon from wild fires, and volcanic ash.

What are 4 sources of particulate matter?

Particulate Matter (PM) Sources. Components of particulate matter (PM) include finely divided solids or liquids such as dust, fly ash, soot, smoke, aerosols, fumes, mists and condensing vapors that can be suspended in the air for extended periods of time.

What is the source of sulfur dioxide?

Sulfur dioxide, SO2, is a colorless gas or liquid with a strong, choking odor. It is produced from the burning of fossil fuels (coal and oil) and the smelting of mineral ores (aluminum, copper, zinc, lead, and iron) that contain sulfur.

How does increase in temperature affect air pollution?

Temperature, Sunlight, and Humidity. Air temperature affects the movement of air, and thus the movement of air pollution. The warmer, lighter air at the surface rises, and the cooler, heavier air in the upper troposphere sinks. This is known as convection and it moves pollutants from the ground to higher altitudes.

What are the factors affecting air pollution?

Factors like the weather, chemical transformations in the air, and transport of pollutants from outside Europe all play a role. This means that a reduction in emissions of a pollutant do not always translate to an equivalent reduction in concentrations of that pollutant.
