Reason : Many organic ions have very high concentrations in natural water, especially in seawater. Urban wastewater always contains a large amount of Cl-, SO42-, PO43, Na+, K+ ions. In industrial wastewater, in addition to the ions mentioned above, there may be highly toxic inorganic substances such as compounds of Hg, Pb, Cd, As, Sb, Cr, F… Sulfates (SO42-), Chlorides (Cl-), Organic substances that are easily decomposed ( Carbohydrates, proteins, fats…) ,Oil, Pathogenic microorganisms .,,,,,,,,
Consequence : Heavy metal contamination Heavy metals present in water are necessary for organisms and humans because they are trace elements that organisms need, but in high concentrations it is a cause of toxicity for humans, causing many dangerous diseases. poor as cancer, mutation. Especially heartbreaking is that it is the cause of cancer villages. Metal ions were found to be strong enzyme inhibitors. They act on the embryo as the -SCH3 and SH groups in methionine and cysteine. Highly toxic heavy metals such as lead (pb), mercury (hg), arsenic (as) … Due to organic compounds There are about 60,105 tons of synthetic organic substances in the world every year, including fuels, colorants, pesticides, growth stimulants, and food additives. These substances are often toxic and have high biological stability, especially aromatic hydrocarbons, which cause strong environmental pollution, causing great impacts on human health. Organic compounds such as: organic compounds of phenol, plant protection compounds such as pesticides DDT, linden(666), endrin, parathion, sevin, bassa… Surfactant detergents High are substances that have negative effects on health and are suspected of causing cancer Bacteria present in wastewater Harmful bacteria in contaminated water from human and animal waste can cause cholera, typhoid, and polio.
