ABSTRACT = {The vegetation around the Lyari river was mostly dominated by monocotyledonous species viz Paspalidium geminatum, Cyperus laevigatus, Chloris barbata and Aeluropus lagopoides. Nineteen species were recorded on the heap area forming six plant communities, whereas, on the plain area seven species with five communities were observed. P. geminatum was the most dominant species on both areas, which indicated its tolerance to sewage pollutant. Edaphic characteristics of both areas (pH, CaCO3, organic matter, Na+, K+, Pb++, Zn++, Cu++) showed a significant correlation with the vegetation types. High soil pH, exchangeable sodium and potassium, zinc, copper with low calcium carbonate and organic matter were observed on the plain as compared to the heap area. However, a similar range of lead level was found on both areas. The availability of copper increased with the increase in soil pH on both areas. The availability of copper concentration was found above the toxic permissible limit of 150 ppm on both areas which ranged from 200 to 640 ppm. The concentration of zinc fell under the permissible toxic level and did not exceed 300 ppm.},
