Remotely sensed image interpretation for assessment of land use land cover changes and settlement impact on allocated irrigation water in Multan, Pakistan.

Industrial revolution and rapid population growth are responsible for alteration of land into different settlements. These changes may lead to change in land use (LU) and land cover (LC). The LULC changes have impact on hydrological regimes including streams flow pattern and allocated irrigation water (water allocation through Warabandi system).

Enhanced decomposition of reactive blue 19 dye in ultrasound assisted electrochemical reactor.

Textile industry effluents contain reactive dyes that may harm our receiving waters. A typical reactive blue (RB) 19 dye is frequently detected in significant concentrations in textile industry effluents. Such dyes have generally shown resistance to decomposition and tend to persist in the environment for long periods and multiply the impacts to water and environment.

Perspectives of low cost arsenic remediation of drinking water in Pakistan and other countries.

Arsenic concentrations above acceptable standards for drinking water have been detected in many countries and this should therefore is a global issue. The presence of arsenic in subsurface aquifers and drinking water systems is a potentially serious human health hazard. The current population growth in Pakistan and other developing countries will have direct bearing on the water sector for meeting the domestic, industrial and agricultural needs.
