Health risk assessment of heavy metals and their source apportionment in drinking water of Kohistan region, northern Pakistan
Abstract The present study was conducted to investigate heavy metal (Cu, Co, Cr, Mn, Ni, Pb, Zn and Cd) concentrations of drinking water (surface water and groundwater) samples in Kohistan region,Expand
Soil and vegetables enrichment with heavy metals from geological sources in Gilgit, northern Pakistan.
The health risks of metals through ingestion of vegetables were of great concern in the study area and the PTF values were lower for all the selected heavy metals, except for Cd. Expand
Determination of major and trace elements in ten important folk therapeutic plants of Haripur basin, Pakistan
Several Pakistani plants are known to be of potential therapeutic value and are used in traditional herbal medicine system of the country. In this work, ten of the most popular routinely usedExpand
Sewage sludge biochar influence upon rice (Oryza sativa L) yield, metal bioaccumulation and greenhouse gas emissions from acidic paddy soil.
SSBC can be beneficial in rice paddy soil but the actual associated benefits will depend on site-specific conditions and source of SS; long-term effects remain a further unknown. Expand
Drinking water quality and human health risk in Charsadda district, Pakistan
Abstract Access to safe drinking water is one of the basic human rights and essential for healthy life. The present study investigated the concentrations of various pollutants in drinking water andExpand
Arsenic health risk assessment in drinking water and source apportionment using multivariate statistical techniques in Kohistan region, northern Pakistan.
The water quality in Kohistan region was evaluated by comparing the physio-chemical parameters with permissible limits set by Pakistan environmental protection agency and world health organization and most of the studied parameters were found within their respective permissible limits. Expand
Heavy metals in agricultural soils and crops and their health risks in Swat District, northern Pakistan.
The health risk assessment revealed that there was no health risk for most of the heavy metals except Cd, which showed a high level of health risk index (HRI⩾10E-1) that would pose a potential health risk to the consumers. Expand
Effects of Cd and Pb on soil microbial community structure and activities
Toxicological effects of heavy metals on soil microbial community structure and activities depend largely on the type and concentration of metal and incubation time, and the enzyme inhibition extent was obvious between different incubation periods. Expand
The uptake and bioaccumulation of heavy metals by food plants, their effects on plants nutrients, and associated health risk: a review
Consumption of vegetables grown on metal-contaminated soil were nutrient deficient and consumption of such vegetables may lead to nutritional deficiency in the population particularly living in developing countries which are already facing the malnutrition problems. Expand
Health risks associated with heavy metals in the drinking water of Swat, northern Pakistan.
Multivariate and univariate statistical analyses showed that geologic and anthropogenic activities were the possible sources of water contamination with heavy metals in the study area, indicating no health risk to the local people. Expand
