Abstract
In the present study, an assessment of heavy metal content in soil and food crops (wheat, rice, maize grains and mustard seeds) and associated health risks was carried out for residents of Ropar wetland and its environs. All the soil samples had high cadmium and cobalt contents, whereas, all crop samples had high contents of cobalt and lead. Bioconcentration factor (BCF) analysis indicated that rice grains act as hyper-accumulators of chromium (BCFâ¯=â¯17.98) and copper (BCFâ¯=â¯10.91), whereas, maize grains act as hyper-accumulators of copper (BCFâ¯=â¯30.43). One-way ANOVA suggested that heavy metal content in food crops varied significantly at pâ¯â¤â¯0.05 for different sites, indicating anthropogenic contribution of heavy metals in agricultural fields. Dietary intake of cobalt via all food crops posed higher non-cancer health risk to residents in comparison to other heavy metals. Chromium posed highest cancer risk through consumption of wheat grains, being staple diet in study area.
