Untreated sewage is a major water pollutant and widely used for irrigation in the agricultural fields of district Patna, Bihar, India. When sewage, containing heavy metals, irrigated into the agricultural fields, it enters into the human food chain by the process of bioaccumulation and biomagnification. In view of the above fact, the present study was conducted to determine the level of metals in the sewage samples of three major drains namely Mandiri, Rajapur and Pahari situated in the city Patna, Bihar, India, during March 2010 to February 2011. In comparison with other two drains, the metals were found in higher amount in the sewage of Pahari drain throughout the year.
