tailieunhanh - Heavy metal accrual in soils and crops grown in the peri urban areas of Jabalpur district of Madhya Pradesh, India using geospatial techniques

The findings of present study suggested that the pH in soils neutral to slightly alkaline safe in electrical conductivity and low to medium in organic carbon content. Metals concentration was below the permissible limits at 200,400,600 and 800 m, from both side of Omati Nala, in rainy and winter seasons, respectively. In water, pH ranged from to and EC under permissible range. However, Pb and Cr were comparatively higher than the Indian permissible limits. The concentration of Ni, Cr and Cd in rice, wheat and Brinjal was higher than the limit given by WHO/Indian standard. The transfer factor was recorded for these metals in order of Brinjal, followed by the Spinach and Tomato. Result revealed that, the pH had negatively correlated with OC (r=*) and Cr (r=**) in rainy season and similar relationship with EC(r=**), OC (r=**), Cd (r=**) and Pb (r=**) in winter season. While, it had significant positive relationship with Cr (r=**). In winter season, the EC had positive and significant relationship with OC (r=*), Cd (r=**) and Pb (r=**). In rainy and winter seasons, the OC showed significant positive relationship with Ni (r=**), Cd (r=*) and Pb (r=*) and Cd (r=**) and Pb (r=*) respectively. The Cd in soil showed significant and positively related with Ni and Cd content in plant. | Heavy metal accrual in soils and crops grown in the peri urban areas of Jabalpur district of Madhya Pradesh, India using geospatial techniques
