Geochemical modeling, source apportionment, health risk exposure and control of higher fluoride in groundwater of sub-district Dargai, Pakistan.
Abstract Highlights Groundwater of Dargai region, Pakistan was analyzed for fluoride concentrations. 51% of groundwater samples exceeded the WHO guideline value of 1.5 mg/L of F–. F– occurrence in water is linked to ion exchange, weathering and mining actions. PCA-MLR results of groundwater shows 64% contamination was due to geogenic source. CaHCO3 (49%), NaHCO3 and NaCl […]

High levels of fluoride contamination in groundwater of the semi-arid alluvial aquifers, Pakistan: evaluating the recharge sources and geochemical identification via stable isotopes and other major elemental data.
Abstract Hydrogeochemical methods were integrated to delineate the geochemical factors controlling fluoride (F–) contamination in groundwater at four sites in the districts of Lahore (Samada) and Kasur (Sari Chimba, Kot Maiga, and Chah Fatehwala) in Panjab province of Pakistan. Hydrochemical data and stoichiometric ratios indicate Na-Cl and Na-HCO3 as the dominant water types with silicate […]

Using urinary fluoride and dental fluorosis as biomarkers of fluoride exposure in brick kiln workers in Balochistan, Pakistan.
Abstract A cross-sectional study was undertaken to determine the level of urinary fluoride and dental fluorosis in brick kiln workers (n=100) and a control group (n=20) in Balochistan, Pakistan. The fluoride level was also assessed in groundwater samples(n=30). The results showed the urinary fluoride level was significantly greater (p<0.05)in the brick kiln workers (0.17–0.30 mg/L) […]

Elucidating various geochemical mechanisms drive fluoride contamination in unconfined aquifers along the major rivers in Sindh and Punjab, Pakistan
Abstract The present study aims to investigate the spatial distribution and associated various geochemical mechanisms responsible for fluoride (F–) contamination in groundwater of unconfined aquifer system along major rivers in Sindh and Punjab, Pakistan. The concentration of F– in groundwater samples ranged from 0.1 to 3.9 mg/L (mean = 1.0 mg/L) in Sindh and 0.1-10.3 […]

Punjab: Concerns on health safety: EPA to monitor drinking water
* Punjab EPA will collect samples to test all the 23 parameters mentioned in the WHO guidelines: Director Monitoring Ali Abbas After a span of over five years, the Punjab Environmental Protection Agency (EPA) has started monitoring drinking water in the province, Daily Times learnt. The media and different forums have been highlighting issues over […]

Fluoride prevalence in groundwater around a fluorite mining area in the flood plain of the River Swat, Pakistan
Highlights Groundwater of flood plain area of river Swat, Pakistan was analysed for F–. Groundwater samples (62.2%) exceeded the WHO safe limit of F– (1.5 mg/L). Fluoride enrichment was due to weathering of rocks and ion exchange processes. Minerals phases suggested both saturated (55%) and unsaturated (38%) groundwater. Health risk via (CFI) identified that groundwater is […]

Toxic water fears in Pakistan region infamous for deformities
Assadullah (Pakistan), May 11 (AFP) Basharat Ali was 15 when his legs began to falter, a condition doctors have blamed on polluted water in a Pakistani region infamous for the deformities that afflict many of its people. Too weak to carry his own schoolbag, he was taken to hospital, where doctors said water laden with […]

Punjab EPA fails to ensure supply of clean drinking water
LAHORE: Punjab Environmental Protection Agency (EPA) has remained unable to fulfil its responsibility of provision of safe drinking water to citizens, Pakistan Today has learnt. Though the provision of safe drinking water is the responsibility of Water and Sanitation Agency (WASA), Public Health and Engineering Department, and municipal and local authorities, but since 2010, the […]

Arsenic and Fluoride Contamination: A Pakistan Perspective (New York: Springer, 2015)
Islamabad – Pakistan is a water-stressed country, relying more and more on its groundwater resources to cope with its burgeoning population and economic needs. At the same time, unchecked and unregulated industrial and commercial development, low standard agricultural practices across the country are threatening to poison the groundwater and render it unfit for human consumption, […]
