This water pollution has become a great threat to existence of plants and animals life. Pakistan tanning industry is a major contributor of chromium pollution. There are about 750 tanneries in different provinces of Pakistan and Kasur city has more over 230 tanneries in different areas. In this process different types of waste are released which contain chromium, salts, ammonia and organic compounds and it enters in our food chain through irrigation system and cause serious diseases such as cancer, lungs infection, liver infection and respiratory diseases. Therefore special attention on the management of industrial waste water is needed. The present study was carried out to investigate the Physico-chemical properties of tannery waste water and their impacts on the seed germination of Onion and Cauliflower plants. Samples were collected from Kasur Tannery Waste Management Agency (KTWMA) near Dipalpor road. Seeds were germinated in petri dishes for 14 days under control conditions. Different concentrations of diluted tannery effluents was applied ranges from; 0 %, 10 %, 25 %, 50 %, 75 %, 100 % respectively. All physico-chemical parameters of effluents were analyzed such as Color, odor, EC, pH, TDS, TSS, Na, K, Ca, P, Cl, BOD, CO3 , HCO3, heavy metals Fe, Pb, Zn, Cu, Ni, Zn, Mn, Cr, Mg. At different time intervals rate of germination was measured and morphological parameters of plants were examined such as shoot and root length, fresh and dry weigh, seedling vigor index after harvastation. Antioxidant enzymes such as Catalase, Peroxidase and Superoxide dismutase were estimated. After digestion of seedlings heavy metals Summary 72 such as chromium, iron, copper, zinc, lead, and nickel were determined. SPSS software was used to apply descriptive statistics and ANOVA 1. Results showed that all physico chemical parameters were higher form prescribed values except pH, TDS and Cu recommended by NEQS. All observed parameters of both plants included seed germination, root length, shoot length, seedling length and seedling vigor index, fresh and dry weight strongly depends on concentrations of effluents. All morphological parameters were decreased with the increase of concentrations. Growth of cauliflower seeds was inhibited after T5 treatment whereas in onion plant growth was ceased after T4 treatment. A result of heavy metals showed that amount of chromium was significantly higher in both plants as compared to other metals. Antioxidant assay of enzymes showed that catalatic activity decreases as concentrations of effluents increases whereas Peroxidase and Superoxide dismutase activity increases with the increase of concentrations.

In the process of rapid urbanization industries are being establishing at a high rate and waste water discharges from these industries are unavoidable and lead to cause water and soil pollution. This water pollution has become a great threat to existence of plants and animals life. Pakistan tanning industry is a major contributor of chromium pollution.
