Evaluation And Characterization Of Trace Metals Contamination In The Surface Sediment Using Pollution Load Index PLI And Geo-Accumulation Index Igeo Of Ona River Western Nigeria

The levels of the detectable heavy metals were all above regulatory limits, with significantly higher concentrations in sediments than in water columns and

After a preliminary characterization of the materials (organic matter content, volatile solid, and heavy metals content), heavy metal accumulation in soil caused by

The exploitation of the local rivers Guadiana and Ardila is confirmed by the presence of freshwater shells (Unio delphinus and Potomida littoralis); whereas trad- ing activity with

For the purpose of this work, data used refers to the 4 th wave (last wave until recently). 9 Individual calibrated weights developed by SHARE were considered in

Thus, the point source pollution catchment showed higher level of metals in upper sediment layers, whereas, for non-point pollution, levels of metals varied widely over time,

The chemometric statistical approach was applied to evaluate the level of metals accumulation in sediment and to identify the probable pollution sources in the

The objectives of the present study were to: 1) build a model for predicting the relationship of Pn, PAR, and I (the relative pollution index) in a contaminated environment; and

The epiphytic moss (Pylaisia polyantha) growing in different zones of the city of Rostov-on-Don, was used for the heavy metals pollution biomonitoring of urbosystems.. The
