Abstract:

Purpose: Human beings are exposed to heavy metal stress by the intake of richly contaminated food crops that are chief part of food chain. We studied various parameters in wastewater irrigation based food-crops in which the health risk index (HRI) calculation was the major concern. Methods: Different plant parts like grain and shoot were collected to study iron (Fe) concentrations through atomic absorption spectrophotometer in forages whilst soil and irrigating water samples were also studied in various districts of Punjab province in Pakistan. Our present findings also emphasized on the assessment of Translocation factor (TF), Bio-concentration factor (BCF), Daily intake of metal (DIM), Health Risk Index (HRI) and Enrichment factor (EF) and Pollution load index (PLI). Results:In this experimentation, most of the Fe concentration was found higher in wastewater irrigated site. When wastewater irrigation method was used for agricultural land, the highest Fe concentration in grain was noticed as 3.45 mg/kg and in water samples observed as 3.27 mg/kg. Soil samples with wastewater irrigation showed higher level of PLI than those exhibited by control treatment. Bio-concentration of Fe was noticed higher in millet samples at Lahore as 22.07 mg/kg. The values of health risk index of Iron vary from 0.001 to 0.021 mg/kg and are lower than critical value. Conclusion:It is suggested that wastewater must be treated properly before agricultural use to lessen addition of heavy metals in the cereal crops and implement safe practices for wastewater usage.
