Name the 8 Types of Water Pollutants. Industries use a variety of chemicals for the processing of raw materials to obtain good-quality products within a short period of time and economically. The Stockholm Convention on Persistent Organic Pollutants, which was adopted in 2001 and entered into force in 2004, is a global treaty whose purpose is to safeguard human health and the environment from highly harmful chemicals that persist in the environment and affect the well-being of humans as well as wildlife. R.M 2 Anand .R. Groundwater pollution due to anthropogenic and natural activities is a cause of concern. For NP/cellulose hybrid composites, most of the studies are centered on catalytical treatment of organic pollutants, and research on catalytic reduction of inorganic pollutants is limited. 7) radioactive pollutants. Rising demands on the water supply only aggravate the problem. Organic and inorganic. Reference: Inorganic pollutants which are usually nitrogen based, tends to increase the concentration of hydrogen ions in water without much acid neutralizing ability being added, resulting in an increased acidity of the water.This as well as the fact that a nitrate was used as the inorganic pollutant, resulted in this hypothesis (3). Low levels of organic matter, iron oxides and high temperature may negatively impact biota and aquifer. Zeolites are well known for their ion exchange, adsorption and acid catalysis properties. Organic Pollution verses Inorganic Pollution. The increasing need to reuse water calls for better wastewater treatment. According to Dr. Norman Walker, over a 70-year lifespan, a person will be drinking about 200 to 300 pounds of rock that our body cannot use if it is not R/O ( reverse osmosis) water. Sewage is the primary source of the first three types. Discussed organic pollutants remediation techniques in detail. Every class of pollutants has its own specific ways of entering the environment and its own specific dangers. General types of water pollutants include pathogenic organisms, oxygen-demanding wastes, plant nutrients, synthetic organic chemicals, inorganic chemicals, microplastics, sediments, radioactive substances, oil, and heat.
