Pakistan ranks at number 80 among 122 nations regarding drinking water quality. Drinking water sources, both surface and groundwater are contaminated with coliforms, toxic metals and pesticides throughout the country. Various drinking water […]Pakistan
Lithological influences on occurrence of high-fluoride groundwater in Nagar Parkar area, Thar Desert, Pakistan.
Abstract Factors regulating the occurrence of high fluoride (F(-)) concentrations in groundwater near Nagar Parkar Town, SE corner of Pakistan have been investigated considering lithological influences. F(-) ion concentrations in groundwater range up to 7.85 with mean value of 3.33 mg L(-1). Plots of major elements and their normative mineral composition reflect granitic composition of […]Pakistan
Karachi: Mysterious disease strikes children in coastal areas of city
KARACHI: A strange disease has spread in the coastal belt of Karachi paralysing the lower limbs and some times the arms and other body parts of the victims, the majority of whom are children. Earlier, there was an outbreak of a similar disease in Achhro Thar (White Desert) of district Sanghar and other areas of […]Pakistan
Geochemical factors controlling the occurrence of high fluoride groundwater in the Nagar Parkar area, Sindh, Pakistan.
Abstract Fluoride concentrations in groundwater near Nagar Parkar in the Thar Desert of southeastern Pakistan range from 1.13 to 7.85 mg/l, and roughly 78% of the samples contain fluoride in concentrations that exceed the drinking water standard of 1.5mg/l set by WHO. The groundwater is alkaline (pH 7.1-8.4), brackish (TDS 449-15,933 mg/l), and classified as […]Pakistan
Sources of arsenic and fluoride in highly contaminated soils causing groundwater contamination in Punjab, Pakistan.
Abstract Highly contaminated groundwater, with arsenic (As) and fluoride (F(-)) concentrations of up to 2.4 and 22.8 mg/L, respectively, has been traced to anthropogenic inputs to the soil. In the present study, samples collected from the soil surface and sediments from the most heavily polluted area of Punjab were analyzed to determine the F(-) and […]Pakistan
Achhro Thar : Contaminated water kills 17 and paralyzes hundreds
KARACHI: Forty-eight year old Sahanti was lying on the sand inside her traditional Thari hut and her daughter was trying to ease her pain by massaging her head. She has been lying in this position for the last 26 years with lower body paralysis, and experts say that underground supplies of water, contaminated with high […]Pakistan
Toxic fluoride and arsenic contaminated groundwater in the Lahore and Kasur districts, Punjab, Pakistan and possible contaminant sources.
Abstract The present study is the first attempt to put forward possible sources of As, F- and SO4(2-) contaminated groundwater in the Kalalanwala area, Punjab, Pakistan. Five rainwater and 24 groundwater samples from three different depths were analyzed. Shallow groundwater from 24 to 27 m depth contained high F- (2.47-21.1mg/L), while the groundwater samples from […]Pakistan
Fluoride concentration in drinking water of Karachi city (Pakistan).
Abstract The ground and municipal water supply samples of Karachi city were analyzed for their fluoride contents. The fluoride contents in water samples collected from the subsurface and river sources were found below the WHO recommended value for the general health of the people. However, in some industrial areas the groundwater sample showed higher level […]Pakistan
Focus on poisoned water and disabilities
LAHORE, 15 December (IRIN) – Tens of thousands of people in the eastern city of Lahore and other cities of the Punjab face a threat from unsafe ground water, which contains dangerously high levels of arsenic. So far, little tangible effort has been made at the official level to counter the problem. The impact poisoned […]Pakistan
Potential fluoride contamination in the drinking water of Naranji area, NorthWest Frontier Province, Pakistan.
Abstract The drinking water of Naranji village and surrounding areas of the NorthWest Frontier Province (NWFP), Pakistan, was analyzed for its fluoride content. The fluoride content of water samples from the springs in the Naranji village goes up to 13.52 mg kg(-1), which exceeds the permissible limit (1.5 mg kg(-1)) set by the World Health […]Pakistan
