“…So far, very limited research works have been executed in the study area in the aspect of hydrogeochemistry and prevalence of dental and skeletal fluorosis and that too also in an isolated manner (Ghosh et al 2010;Majumdar 2011), but in this research work, an in-depth analysis is carried out in both the aspects along with an additional emphasis on the effect of F on intelligence and urinary level of study area population by means of clinical and nonclinical survey.…”

This research work is carried out to evaluate fluoride (F) hydrogeochemistry and its effect on the population of two endemic villages of Birbhum district, West Bengal. Fluoride concentration in drinking water varies from 0.33 to 18.08 mg/L. Hydrogeochemical evolution suggests that ion-exchange mechanism is the major controlling factor for releasing F in the groundwater. Most of the groundwater samples are undersaturated with respect to calcite and fluorite. Health survey shows that out of 235 people, 142 people suffer from dental fluorosis. According to fluoride impact severity, almost 80 and 94 % people in an age group of 11-20 and 41-50 suffer from dental and skeletal fluorosis, respectively. Statistically drinking water F has a positive correlation with dental and skeletal fluorosis. Bone mineral density test reveals that 33 and 45 % of the studied population suffer from osteopenic and osteoporosis disease. IQ test also signifies that F has a bearing on the intelligence development of the study area school children. The existence of significant linear relationship (R (2) = 0.77) between drinking water F and urinary F suggests that consumption of F-contaminated drinking water has a major control over urinary F (0.39-20.1 mg/L) excretion.

“…Millions of dollars have been spent around the globe to mitigate fluoride problem in drinking water by utilizing various households and community level solutions (Brindha et al, 2011;British Geological Survey, 2012;Dahi et al, 1996;Dysart ,2008 ;Fawell & Bailey, 2006;Feenstra et al, 2007;Gill et al,2004;Khichar & Kumbhat, 2015;Loganathan et al, 2013;Mackay & Cherry, 1989;Majumdar, 2011;Mohapatra et al, 2009;Pontié et al, 2006;Thole, 2013). But in most cases only limited success was achieved (Gill et al, 2004;Padmasiri, 2000;Piddennavar & Krishnappa, 2013).…”

A wide variety of pump and treat methods like chemical precipitation, adsorption, ion exchange and reverse osmosis have been trialled for many decades for fluoride removal from groundwater, but the problem of fluoride contaminated water remains in many parts of the world largely because these processes require constant monitoring, are expensive to implement and maintain at decentralised scale due to lack of reticulation infrastructure, and possess sludge disposal problem. This paper presents an overview of various fluoride removal processes and the limitations associated with each process and the application of in-situ permeable reactive barrier for remediating fluoride contaminated groundwater is explored, which displays the potential to be a cost effective, low maintenance and energy intensive technology.

“…Arsenic, fluoride and fecal coliform have a negative impact on human health, for instance, as seen in the long term intake of arsenic which causes cancer in the lungs, bladder and skin [51]. However excessive intake of fluoride leads to dental and skeletal fluorosis [52]. Fecal coliform caused water pollution due to pathogens which are disease causing organisms [53].…”

Sustainable urbanization is a challenge to human beings in the modern era of technology. Cities all over the world are facing several problems due to urbanization and industrialization. Urban problems could be assessed through development of indices of urban sustainability on the basis of its three dimensions: environment, economics and social. The present study was conducted to identify indicators to develop indices for assessment of sustainability in some populated cities of Punjab. The study focused on the indicators based on environmental, economic and social development to develop a rational indicator system on the basis of secondary data collected from 2004 to 2014. A total of 40 indicators were identified to assess the urban sustainability progress in Lahore, Rawalpindi, Multan, Gujranwala and Faisalabad cities. The result of the sub-indices indicated that poor performance was evident in the environmental sector, rather than in the economic and social sectors. The cities scored between 0.27 and 0.58 in environmental dimensions, showing a decreasing trend from 2004 to 2014. The declining trend of indices was due to population influx, rapid urbanization, reduction in green areas, industrialization, high level of atmospheric and water pollutants. In case of the economic sector, an increasing trend was observed which indicates the gradual improvement in living standards of people. In the social dimensions of the indicator system, less variations were observed among the cities and ranged between 0.49 and 0.58. Overall, the results of the urban sustainability index showed score was ranges between 0.41 to 0.52. None of the Punjab cities attained the position as a sustainable city (0.75) Lahore (0.52) and Faisalabad (0.52) were ranked as moderately sustainable cities, whereas, Rawalpindi (0.48), Gujranwala (0.47) and Multan (0.41) were ranked as weak sustainable cities. The study highlighted that the urban sustainability indicator system could be useful to determine the existing sustainability in cities of the developing countries for better resource management practices.
