Get Analysis Of Pollution Of River Challawa By Industrial

Chemicals and heavy metals from industrial and municipal wastewater contaminate waterways as well. These contaminants are toxic to aquatic life—most often reducing an organism's life span and ability to reproduce—and make their way up the food chain as predator eats prey.

Sulphur dioxide and Nitrogen dioxide are industrial pollutants.

Industrial discharge contains a large number of hazardous chemicals. It discharges these chemicals directly into the rivers, lakes, or nearby water bodies. These highly toxic chemicals may harm aquatic animals and human beings. Many factories also use freshwater to carry away their waste into the water bodies.

Decayed matter, plant nutrients, synthetic organic chemicals, inorganic chemicals, microplastics, sediments, radioactive substances, oil, antibiotics, pharmaceuticals, personal care products, surfactants, metal ions, and pesticides are the most common contaminants found in wastewater (Petrović et al.

Chemical industries face formidable environmental regulatory challenges in treating their wastewater effluents. Pollutants discharged at petroleum refineries and petrochemical plants include conventional pollutants like oil and grease, and suspended solids, and ammonia, chromium, phenols and sulfides.

Liquid factory waste, smoke, and raw sewage can all be called effluents.

This results in algal clumps, odour, decolouration of the water, extensive growth of rooted aquatic life, extreme oxygen depletion, etc. Moreover, many times this wastewater, when released, leach down the soil and affect the quality of the groundwater adversely.

Industrial effluents are discharged into water bodies without treatment and found to be a major source of toxic heavy metals such as Cr, Cu, Pb, Fe, Mn, Cd, Hg, Ni, Zn, etc. These non-biodegradable heavy metals have detrimental effects on living organisms [109].
