Importance of Water in Environmental Biotechnology

Water is essential for all forms of life on earth and accounts for 70% or more of total cell mass. It carries nutrients to all cells, oxygen to the brain, and helps in absorbing minerals, vitamins, and other substances. Additionally, water flushes out toxins, waste, and aids in regulating body temperature.

Sewage water is the wastewater from a community, consisting of water from the community's water supply, human excreta, used water from bathrooms, food preparation wastes, and laundry.

Household waste, agricultural waste, industrial waste, radioactive pollution, river dumping, and marine dumping.

<p>Eutrophication refers to the excessive richness of nutrients in a body of water, often caused by runoff from the land, discharge of nitrate or phosphate-containing detergents, fertilizers, or sewage. This leads to dense growth of plant life and depletion of oxygen levels in the water.</p> Signup and view all the answers
