Abstract:

Environmental Pollution is increasing day by day due to the release of heavy metals contaminated wastewater from industries. Phytoremediation is an ecofriendly and emerging technique for the restoration of environment contaminated with heavy metals. This study was designed to determine the heavy metal uptake potential of some weed species; Amaranthus viridis, Calotropis procera and Parthenium hysterophorus which were growing naturally in vicinity of five industrial wastewater points of Lahore, Pakistan. The wastewater was collected, filtered and the physicochemical properties were measured. The soil and plant material were also collected, dried and ground firmly. Acid-digestion of soil and plant material was done by adding 3:1 ratio of HNO3 and HClO4. Heavy metals were analyzed in the samples of wastewater, soil and plant leaves by using atomic absorption spectrometer. Two-way Analysis of Variance (ANOVA) was applied for statistical analysis in accordance with COSTAT software package. The results of physicochemical properties of wastewater showed that the Ruhi industrial brook (S2) had highest pH, suspended solids (SS), Total dissolved solids (TDS), biochemical oxygen demand (BOD), chemical oxygen demand (COD) and highest heavy metal values. Plants showed variability in the values of Heavy metals in different sites. Results indicated that A. viridis, C. procea and P. hysterophorus accumulated highest values of As, Cd, Cr, Cu, Pb, Ni and Zn from all sites but P. hysterophorus accumulated more heavy metals as compared to A. viridis and C. procea. It is suggested that these three weeds; A. viridis, C. procea and P. hysterophorus have great potential for heavy metal uptake and are suitable for phytoremediation purpose.
