Sushma Jain and Avdhesh Singh

In Jhunjhunu city, sewage water is used for irrigation in vegetable farms near Nayawas and Mandrella by-pass. This polluted water degrades land quality and deteriorate soil productivity. Therefore 12 soil samples were collected from the vegetable farms. The heavy metals Fe, Cu and Zn were determined by using atomic absorption spectrophotometer. The results show the presence of these heavy metals beyond the limits of Indian standards. Therefore, the sewage water should be used after proper treatment.
