Abstract
Vegetables grown in metal-contaminated soil are a potential hazard to human live. Trace metals are introduced into grown vegetables through irrigation of unsanity, industrially polluted water in the field. A soil clean-up analysis of seven industrially polluted sites of Faisalabad district to determine trace metal accumulation in okra. The experiment was based on a completely randomized design where soil from each sample site was placed in a small lysimeter with variation in water capacity (75, 100, and 125% field capacity) with three replicates. After 45 days of germination, the okra plants were harvested and further divided into root and shoot components. The results showed that soil from different locations in Faisalabad and different levels of available water capacity (AWC) significantly affected the root morphological characteristics and total fresh biomass of okra. Contamination of soil with trace metals significantly affected the physical properties of soil and thus resulted to minimization of root morphology and fresh and dry biomass of okra. In the current study, soils irrigated with industrially contaminated with chromium 0.63-2.53 ppm, lead 0.008-0.6 ppm, zinc 3.16-12.24 ppm and cadmium 0.007-1.65 ppm, which pose a potential risk to the health of domestic people. The results indicated a potential human exposure mechanism for gradual poisoning by trace metals related to indirect use of crops grown on soils contaminated with heavy metals and irrigated by contaminated water sources. The current study concluded that Faisalabad industrial wastes have been identified as the source of trace metal contamination in the surrounding agricultural soils of Faisalabad.
