Abstract: In present research work four different peri-urban agricultural areas of Punjab (Gujranwala, Kasur, Lahore and Multan) were surveyed in the first phase (2012-2013). Total 138 contaminated soil samples, 131 waste water samples and 131 native plant samples were collected and analyzed. Physiochemical analysis of soil and waste water samples was done and also processed for fungal isolation. Native plants samples were analyzed for heavy metal contents (Cu, Cd, Pb and Cr). In overall assessment Pb, Cd and Cr were noticed above recommended permissible values in soil samples of all the study areas. Whereas Cu was found above the recommended permissible limits only in samples of Multan and Gujranwala as compared to Kasur and Lahore soil samples. Physiochemical analysis of wastewater samples also showed high EC, bicarbonates, chlorides and sodium in collected samples of Multan however, Kasur samples showed salinity problems. In case of heavy metals in waste water samples Pb and Cd contamination was found in all the four areas. But Cr contamination was found more in Multan and Lahore waste water samples. Native plants of Multan were found contaminated with Cd. In case of Kasur Cr was found maximum in native plant samples. Plants samples of Lahore were also showing Pb, Cu, Cr and Cd contamination. In case of fungal diversity maximum number of fungi were isolated from heavy metal contaminated samples of Multan, Kasur, Lahore and Gujranwala.
