Heavy metal pollution assessment in various industries of Pakistan

Water pollution is a source of danger to the health of people living in developing countries such as Pakistan. The main industries located at various industrial zones of Pakistan cause water pollution, which ultimately result in various diseases. The aim of the present study was to study the concent...

Description
Summary:Water pollution is a source of danger to the health of people living in developing countries such as Pakistan. The main industries located at various industrial zones of Pakistan cause water pollution, which ultimately result in various diseases. The aim of the present study was to study the concentrations of essential and toxic metals (Na, K, Cu, Zn, Fe, Ca, Pb and As) in the drained water of three main industrial estates of Pakistan, i.e., Industrial Estate No. 1 Peshawar, Small Industrial Estate No. 2 Gujranwala, Industrial Estate Hattar Haripur, and in Warsak Canal (industrially pure water) with the help of atomic absorption spectroscopy and flame emission spectroscopy. The study showed high Pb and As levels originating from industries. The concentrations of Pb and As ranged from 0.04 to 0.942 mg/L in all the samples. These have been extensively used for irrigation since the last five decades. The elevated concentrations of heavy metals are continuously entering into the food chain through agriculture leading to serious health hazards and a threat to the sustainability of local ecosystem.
