The controversy related to the environment pollution is increasing in human life and in the eco-system. Especially, the water pollution is growing rapidly due to the wastewater discharge from the industries. The only way to find the new water resource is the reuse of treated wastewater. Several remediation technologies are available which provides a convenience to reuse the reclaimed wastewater. Heavy metals like Zn, Cu, Pb, Ni, Cd, Hg, etc. contributes various environmental problems based on their toxicity. These toxic metals are exposed to human and environment, the accumulation of ions takes place which causes serious health and environmental hazards. Hence, it is a major concern in the environment. Due to this concern, the significance of developing technology for removing heavy metals has been increased. This paper contributes the outline of new literature with two objectives. First, it provides the sketch about treatment technologies followed by their heavy metal capture capacity from industrial effluent. The treatment performance, their remediation capacity and probable environmental and health impacts were deliberated in this review article. Conclusively, this review paper furnishes the information about the important methods incorporated in lab scale studies which are required to identify the feasible and convenient wastewater treatment. Moreover, attempts have been made to confer the emphasis on sequestration of heavy metals from industrial effluent and establish the scientific background for reducing the discharge of heavy metals into the environment.

Problemática del arsénico en la llanura sudeste de la provincia de Córdoba: Biotransferencia a leche bovina

Se determino la composicion mineral del agua de bebida animal en tambos para analizar su contribucion al requerimiento mineral diario de los animales. Se recolectaron muestras de agua en 24 establecimientos lecheros ubicados en la zona sudeste de la provincia de Cordoba. Se determino pH y conductividad ( in situ ), Na + , K + , Ca 2+ , Mg 2+ , Cl - , SO 4 2- , HCO 3 - y solidos totales disueltos (STD). De acuerdo con la clasificacion de calidad de agua de bebida animal por su contenido de STD, en las aguas semisurgentes (80-120 m de profundidad) un 8% resulto deficiente , un 50% muy buena , un 25% buena, un 17% aceptable y ninguna de las muestras puede considerarse como mala para consumo animal. En la napa freatica (3-12 m de profundidad), el 25% de las muestras resultaron muy buenas , 19% buenas , 19% aceptables , mientras que el 37% entran en la categoria de mala calidad. Considerando el contenido de macrominerales en las aguas de bebida clasificadas como muy buenas , buenas y aceptables , se calculo el porcentaje de los requerimientos diarios del animal para cada elemento que aportaria el agua. Se observa que un alto porcentaje de los requerimientos de cloruro de sodio y azufre quedan cubiertos por el agua de bebida, fundamentalmente en aquellos establecimientos que utilizan pozos semisurgentes.

Contenido de macrominerales en el agua de bebida de tambos de la provincia de Córdoba (Argentina) y su relación con los requerimientos de bovinos de leche

Chemical composition of the cell wall of the tree fungus Cyttaria harioti Fischer

The sulfation of heparan sulfate, 2-sulfation of D-glucuronic acid, is regioselective as has been reported. 4-O-substituted D-glucuronic acid derivatives were synthetized in this work to study the sulfation of monosacharide models. No selectivity between hydroxyls 2- and 3- was obtained.
