“…While the full health effects of arsenic in Pakistan are not yet known, various studies over the past decade have uncovered arsenic-related skin disorders ( 29 , 31 ) and high levels of arsenic in blood and hair samples ( 32 , 33 ) from people living in predominantly rural areas with high exposure to arsenic in groundwater. Food crops in the Sindh ( 34 , 35 ) and Punjab (own measurements) provinces also indicate a potentially severe health threat due to plant uptake of arsenic via irrigation water extracted from shallow Holocene aquifers.…”

“…The weathering of mica and granite in the study area produces abundant F − bearing minerals that are easily leached out and dissolved in groundwater. Thus, another source of high F − levels in groundwater includes leaching from fluoride-bearing minerals (Shah and Danishwar 2003;Naseem et al 2010;Brahman et al 2014). Weathering, industrial wastes (Siddique et al 2006), agricultural fertilizers, brick production, organic landfills, and the combustion of coal all release fluoride into the air which later reaches the soil with rain (Farooqi et al 2007b;Brahman et al 2013a).…”

“…These nations include China, India, Pakistan, Sri Lanka, Ghana, Germany, Senegal, Turkey, Algeria, Kenya, Uganda, Tanzania, Japan, Ethiopia, South Africa, Mexico, New Zealand, Thailand, and Argentina (Rafiq et al 2009). Arsenic and F − in groundwater are common in arid and semi-arid regions of the world (Farooqi et al 2007;Currell et al 2011;Brahman et al 2013aBrahman et al , 2014. Higher As and F − concentrations in water are characterized by a high redox potential and exhibit Na + -HCO 3 -groundwater type (Semedley and Kinniburgh 2002;Pauwels and Ahmad 2007;Kim et al 2012).…”

“…The sources of As in Pakistan include natural processes such as the dissolution of As compounds adsorbed onto pyrite ores. Fluorides are naturally released into the groundwater by the dissolution of fluoride-containing rocks and anthropogenic production of phosphate fertilizer, insecticides, herbicides, semi-conductors, timber preservatives, mining and smelting, and coal combustion (Mondal et al 2006;Bundschuh et al 2011;Brahman et al 2013aBrahman et al , 2014.…”

The present study discusses elevated groundwater arsenic (As) and fluoride (F(-)) concentrations in Mailsi, Punjab, Pakistan, and links these elevated concentrations to health risks for the local residents. The results indicate that groundwater samples of two areas of Mailsi, Punjab were severely contaminated with As (5.9-507 ppb) and F(-) (5.5-29.6 ppm), as these values exceeded the permissible limits of World Health Organization (10 ppb for As and 1.5 ppm for F(-)). The groundwater samples were categorized by redox state. The major process controlling the As levels in groundwater was the adsorption of As onto PO4 (3-) at high pH. High alkalinity and low Ca(2+) and Mg(2+) concentrations promoted the higher F(-) and As concentrations in the groundwater. A positive correlation was observed between F(-) and As concentrations (r = 0.37; n = 52) and other major ions found in the groundwater of the studied area. The mineral saturation indices calculated by PHREEQC 2.1 suggested that a majority of samples were oversaturated with calcite and fluorite, leading to the dissolution of fluoride minerals at alkaline pH. Local inhabitants exhibited arsenicosis and fluorosis after exposure to environmental concentration doses of As and F(-). Estimated daily intake (EDI) and target hazard quotient (THQ) highlighted the risk factors borne by local residents. Multivariate statistical analysis further revealed that both geologic origins and anthropogenic activities contributed to As and F(-) contamination in the groundwater. We propose that pollutants originate, in part, from coal combusted at brick factories, and agricultural activities. Once generated, these pollutants were mobilized by the alkaline nature of the groundwater.

“…According to a report by the World Health Organization (WHO), more than 200 million people worldwide are affected by high concentrations of fluoride [25]. The concentration of fluoride in water is affected by several factors [6], the most important of which is the type of bedrock on which water flows [26]. Groundwater flowing on crystalline, volcanic, sandstone bedrocks has a higher concentration of fluoride [27][28][29].…”

a b s t r a c tFluoride in drinking water is an important chemical species with regard to public health considerations, although a fluoride concentration of about 1.5 mg L -1 in drinking water can decrease tooth decay and higher concentrations cause health problems. The concentration of fluoride in water is affected by some chemical characteristics. This study aimed to evaluate the relationship between fluoride and other chemical parameters (pH, Turbidity, EC, TDS, TH, ALK, Cl -, SO 4 2-, NO 3-, NO 2-, Ca 2+ , Mg 2+ , Na + , K + , PO 4 3-) in water bodies located in Showt, West Azerbaijan Province, Iran. Sample preparation and analysis were performed according to standard methods. A wide range of fluoride concentrations was measured in this study (0.0-5.5 mg L -1 ). The results indicated that alkalinity and Na + have a significant positive relationship with fluoride concentrations in water wells. Nevertheless, total hardness (TH) showed an inverse relationship with fluoride concentration. In addition, for a one-unit increase in alkalinity and Na + concentration, the average amount of fluoride in water increased by 0.0028 and 0.16, respectively. Furthermore, for a one-unit increase in total hardness, the average amount of fluoride in water decreased by 0.005. In conclusion, fluoride concentration was affected by numerous factors such as hardness, alkalinity, and Na + concentration. The findings of this study suggest that a suitable treatment of the groundwater is needed in contaminated areas before its use for drinking.
