Bio-chemical changes in leafy vegetables grown on contaminated and Non-contaminated soils

Departmental Research
Experiment Background
Many researchers and scientists from India and abroad, after studying soil (Kumar and Srikantaswamy, 2012; Jayashreeet al. 2012; Dheeba B. et al. 2012), water (Lokhandeet al., 2011; Kumar et al. 2011) and plant samples (Sharma et al. 2009; Tanushreeet al. 2011) from industrial and adjacent areas, reported varying degrees of contamination of heavy metals in soil-water-plant systems which ultimately were polluting not only aquatic resources and lives but also agricultural and other plants/crops which later on became a part of food chain and thereby becoming harmful to human and animal kingdom. Together with rapid worldwide industrialization, heavy metals have become one of the major types of environmental contaminants, particularly in soils (Qin et al., 2012). These elements can be phytotoxic and harmful to vital microbial processes in nutrient cycling (Oliveira et al., 2005). Chemical analyses provide information only referring to the accumulation of these contaminants in soils, but they will not indicate the consequences they have on soil biochemical composition and metabolism. Keeping all the above points in view, a pot experiment has been planned on the evaluation of bio-chemical properties of different leafy vegetables grown on contaminated and non-contaminated soil.

Objective
To assess biochemical changes in different leafy vegetables grown in contaminated and non-contaminated soils
To assess the accumulation of heavy metals in leafy vegetables
To evaluate nutrient content of leafy vegetables grown in contaminated and non-contaminated soils
Phytoaccumulation of heavy metals and Bio-concentration Factor (BCF) of shoot and root in the leafy vegetables grown in contaminated and non-contaminated soils
First year soil survey will be conducted from leafy vegetables growing around Ankleshwar and Bharuch region. identify various locations of both the areas for digging out representative soil samples (0-15 cm) using GPS system. Based on preliminary survey and other information of surface samples (total 50 nos.) will be done from the above areas.
Soil chemical analysis will be done and afterwards contaminated and non-contaminated soils on the basis of maximum permissible limits of heavy metal concentration as given by WHO(1996).
Pot culture trial will be conducted for soil and plant samples analysis at College.
