Why does dissolved oxygen decrease in water?
Dissolved oxygen in water decreases due to factors like temperature increase, pollution, and excessive plant growth, which can lead to oxygen depletion and harm aquatic life.
What can cause dissolved oxygen levels to decrease?
Dissolved oxygen levels can decrease due to factors such as high water temperature, increased organic matter or pollution, excessive plant growth leading to oxygen depletion during decomposition, and reduced mixing of water layers.
What can A body of water can be depleted of its oxygen by .?
A body of water can be depleted of oxygen by excessive nutrient runoff (eutrophication), which leads to algal blooms that consume oxygen as they decompose. Pollution from industries or sewage can also introduce harmful substances that reduce oxygen levels in the water. Additionally, temperature changes and natural processes like decomposition can contribute to oxygen depletion.
Which type of chemical lead to lack of dissolved oxygen?
Nutrient pollution, specifically excess nutrients like nitrogen and phosphorus, can lead to an overgrowth of algae. When the algae die and decompose, bacteria use up the dissolved oxygen in the water, causing hypoxia or oxygen depletion.
What interaction with the earth's system has resulted in resources depletion and water and air pollution?
human interaction
Why does eutrophication lead to depletion of oxygen in water?
Eutrophication occurs when excessive nutrients (such as phosphorus and nitrogen) enter a body of water, causing overgrowth of algae and other aquatic plants. As these plants die and decompose, bacteria consume oxygen during the decomposition process, leading to oxygen depletion in the water. This depletion can harm aquatic organisms and disrupt the balance of the ecosystem.
Name of 8 type of water pollution?
8 types of water pollution include: Nutrients Pollution Surface Water Pollution Oxygen Depleting Ground Water Pollution Microbiological Suspended Matter Chemical Water Pollution Oil Spillage
How the growing industrial activity is responsible for depletion of water table?
Industrial activity can lead to the depletion of the water table through excessive water extraction for manufacturing processes and cooling purposes. Additionally, pollution from industrial runoff can contaminate groundwater, making it unsuitable for consumption and further reducing available water sources. The overall increase in demand for water by industries can stress local water resources, leading to a decline in the water table level.
why is phosphates banned?
Phosphates are banned in some products like laundry detergent and dishwashing soap because they can contribute to water pollution by promoting excessive growth of algae in water bodies. This can lead to oxygen depletion and harm aquatic ecosystems. Efforts to reduce phosphate pollution aim to protect water quality and support the health of aquatic organisms.
What type of chemical pollutant are responsible for the ozone depletion and where do these chemicals come from?
water vapor, oxidized
What are the Practices That causes water pollution?
the answer is co2 mixes with oxygen
What are the factors are responsible for river pollution?
Oil slicks, deforestation , dumping of solid waste, and dirty water from factories are some of the factors responsible for the pollution of rivers.
