Fluoride is one of the most commonly found elements in the earth’s crust. It is naturally found d in water and helps in healthy tooth development and cavity prevention. However its high concentration in water can be harmful to human health. The amount of Fluoride (F) occurring naturally in groundwater is governed principally by climate, composition of the host rock, and hydrogeology. As per the World Health Organization and Indian Council of Medical Research the permissible limit to fluoride in drinking water is 1.5mg/L. Anything more than this value can cause fluorosis (dental and skeletal), which can affect the bones and teeth. In the backdrop of this aspect of water quality, this paper in RASĀYAN Journal of Chemistry,  tries to assess the exposure to fluoride through drinking water consumption and to elucidate fluoride endemic areas through mapping in Unnao district of Uttar Pradesh.

Introduction

Prolonged and recurrent drought, being experienced in India and various parts of south Asia, is the manifestation of climate change, partly caused by human interventions. Drought has been one of the primary reasons for widespread poverty and environmental degradation including deteriorating water quality and water security. The world has been more drought-prone during the past 25 years and the vulnerability of tropical countries to drought is likely to increase (Inter-governmental Panel on Climate Change, 2007).

Industrial effluents and sewage water are being diverted to the river Ganga by the cities and towns through which it passes. Nestled on the banks of Ganga, Kanpur, a highly urbanized and industrial city is polluting it most. Apart from the Government of India’s recently constituted National Ganga River Basin Authority, civil societies and NGOs too are putting rigorous efforts to make Ganga pollution free. Though the city has several big and small industries, the leather industries located in Jajmau, the oldest part of the city add to the problem of pollution in the river to a large extent.
