Water is polluted with zinc, due to the presence of large quantities of zinc in the wastewater of industrial plants. This wastewater is not purified satisfactorily. One of the consequences is that rivers are depositing zinc-polluted sludge on their banks. Zinc may also increase the acidity of waters.

The ,plating, baths are usually acidic in nature and contain sulfuric, hydrochloric or nitric acids. Alkaline baths containing carbonate, hydroxide and cyanide are also used. Cyanides are used in ,plating, baths as they are good oxide solvents and they yield a brighter and less porous plates. 17. Effects on sewers:

Think of the effects it can have on the ,plant,, animal or human body. Acid rain raises the level of heavy metals, some of which are poisonous, in drinking water supplies. Polluted acidic waters contain higher than average levels of heavy and toxic metals, carbon monoxide, volatile organic compounds (VOCs), photochemical oxidants, and a laundry list of other toxins that cause serious health threats.

As shown in Figure 1, Zn concentration and total concentration of the remaining metals in the effluent decreases as the A/O ratio reduces. It is interesting to notice that Zn concentration decreases with A/O ratio for the whole range studied, reaching a very low concentration (,high, Zn extraction) at A/O ratio ³ 1/2.
