Analysing the effect of industrial waste on river Ravi [Pakistan]
2003
Naseer, N. (Economic Affairs Div., Islamabad (Pakistan))
In the research on river Ravi, I tried to find out the effect of industrialization that has turned the river into a sewer. The finding of my research were: a) Industrial pollution is present in the river but its harmful effects were not seen as most of the pollutants are washed and diluted during the monsoon season b) Fluoride in the river water was the main cause of bone deformity disease that hit a downstream village in 1999. Prior to this, no study on the river has actually considered Fluoride as a potent threat. Studies on river Ravi so far suggested that the concentration of certain elements, ammonia and faecal coliform are high. However, none of the studies have taken into account fluoride concentration, which eventually had a phenomenal effect on the village downstream. The studies, findings and finally the outbreak of disease conveyed that not all the parameters were taken into account during the studies. Fluoride concentration could have long been detected if concentration of all possible heavy metals, trace metals and toxic chemicals had been tested.
