Impact/Purpose:
The development of agricultural and industrial practices globally has resulted in contamination of water bodies predominantly by pharmaceuticals and pesticides because of their toxic and recalcitrant nature. Contamination of water by these compounds, even in very low concentrations (μg L-1), raises significant environmental issues of public concern, and hence their efficient removal from water is of utmost importance. Adsorption is a major technique for wastewater treatment with the use of various adsorbents such as metal oxide compounds, e.g. Fe2O3, ZnO, Al2O3, ZnO-MgO, etc., and carbon-based materials, e.g. graphene oxide, activated carbon, and carbon nanotubes. The cytotoxic effects of pharmaceutical drugs and pesticides in terms of human risk and ecotoxicology are highlighted. The remediation techniques involving adsorption on metal oxides and carbon-based materials is surveyed that will be useful for academic and industrial researchers and water treatment municipalities
Description:
The worldwide development of agricultural and industrial practices has resulted in contamination of water bodies predominantly by pharmaceuticals and pesticides because of their toxic and recalcitrant nature. Contamination of water by these compounds, even in very low concentrations (μg L-1), raises significant environmental issues of public concern, and hence their efficient removal from water is of utmost importance. Adsorption is a major technique for wastewater treatment with the use of various adsorbents such as metal oxide compounds, e.g. Fe2O3, ZnO, Al2O3, ZnO-MgO, etc., and carbon-based materials, e.g. graphene oxide, activated carbon, and carbon nanotubes. The small size of metal oxides and the presence of various functional groups help in increasing their adsorption activity. Carbon-based adsorbents exhibit salient properties such as high surface area, high porosity, easy functionalization, low price, and high surface reactivity. Here we review the cytotoxic effects of pharmaceutical drugs and pesticides in terms of human risk and ecotoxicology. We present also remediation techniques involving adsorption on metal oxides and carbon-based materials.
