摘要：The study is mainly focused on assessment of agricultural soil contamination and its degradation scenario by trace elements which are mainly attained from industrial activity and agrochemicals at Gazipur district. Twenty soil samples were collected randomly from different locations of Gazipur along the river side of agricultural fields. Most of the trace elements concentration is higher than world average. There are two main clusters among trace elements. There are significant positive correlations among the elements according to Pearson Correlation Matrix and minimal to moderate enrichment factor indicates anthropogenic sources. The highest geo-accumulation index are contributing extremely pollution scenario of the study area. Contamination factor indicates that the study areas are both moderately to less contaminated by the heavy metals. Pollution load index analyses indicate that the places are polluted by trace elements and their sources are mostly industrial processes and agrochemicals. Principle component 1 denotes mainly natural source of elements. But principle components 2 stands for mainly anthropogenic sources. So, it is evident that the soil in the study area has been degrading severely through trace elements contamination mostly from anthropogenic sources and it has great possibility that plants would uptake heavy metals from the soil.
