Multivariate statistical analysis of heavy metals pollution in industrial area and its comparison with relatively less polluted area: A case study from the City of Peshawar and district Dir Lower

Estimation of some heavy metals in polluted well water and mercury accumulation in broiler organs

“…Among various pollutants in the environment, heavy metals are directly related to diseases in humans. Although it is difficult to classify the trace metal into essential and toxic groups, yet it is a well known fact that an essential metal becomes toxic at sufficiently high intakes (Khurshid and Qureshi 1984;Harter et al 2002;Anne et al 2007;Akbar Jan et al 2010). Lead may enter the environment during the mining, smelting, refining, and manufacturing processes and by the use of lead containing products.…”

Reduction in Organic Waste through Recovery from WastePaper Recycling Mill

“…Studies conducted in 2010 revealed that this wastewater is a continuous source of threat for receiving water body, the Kabul River. It also contaminates the drinking water quality of the nearby areas [11][12][13][14][15][16].…”

“…This wastewater is discharged into industrial drain without any treatment and then finally it joins river Kabul. Such type of untreated wastewater is a threat to aquatic organisms [16]. Therefore, to keep recovering raw materials and keep paper mill environment friendly, arrangements for effluents treatment is considered important for each industry.…”

Assessment and Multivariate Analysis of Metals in Surgical Instrument Industry Affected Top Soils and Groundwater for Future Reclamation

“…PCA provides a better understanding of the relationships among the variables by dividing them into various groups and reducing the dimensionality (Jan et al, 2010;Tariq et al, 2006). Thus Varimax normalized factor loadings were recorded for the metal data collected from the three media and incorporated in Table 5.…”
