Abstract The problem associated with the disposal of sewage water and municipal waste are important aspects of water pollution which should be considered in the context of wider environmental problem. Application of waste water for irrigation purposes has increased over the past years. This waste water also contains high amounts of trace elements and heavy metals. Waste waters are contaminated with trace elements like Lead (Pb), Cadmium (Cd), Nickle (Ni), Mercury (Hg), Uron (U), Copper (Cu), Zinc (Zn), Boron (B), Cobalt (Co), Cromium (Cr), astonium (As), Molibidinum (Mo), manganese (Mn), etc. Many of these are non-essential and are toxic to plants, animals and human beings. Sensitivity of vegetable crops like lettuce, parsley, cabbage, onion, spinach, carrot, funnel, radish, tomato etc. to water pollutants has been reported. Waste water is suitable for irrigation if the content of toxic elements is reduced considerably. Top |
