Effects of sediment geochemical properties on heavy metal bioavailability.

Although water constitutes 71% of the earth's surface, only 0.3% of it is available as fresh water for human use. Moreover, the quality of fresh water in ground and surface systems is of great concern, as potable water needs to have appropriate mineral content. Ground and surface water quality in rural and urban environments is affected by both natural processes and anthropogenic influences. Because of this, water is becoming scarcer as the population increases across the world. Natural processes leading to changes in water quality include weathering of rocks, evapotranspiration, depositions due to wind, leaching from soil, run-off due to hydrological factors, and biological processes in the aquatic environment. These natural processes cause changes in the pH and alkalinity of the water, and also phosphorus loading, increase in fluoride content and high concentrations of sulphates. Anthropogenic factors affecting water quality include impacts due to agriculture, use of fertilizers, manures and pesticides,...

Influences of natural and anthropogenic factors on surface and groundwater quality in rural and urban areas

Evaluation of boron removal by adsorption on solids

The chronic toxic effects of excessive intake of fluoride, or fluorosis, are usually observed as skeletal abnormalities or damage. The effects range from stiffness and rheumatism to a permanent crippling skeletal rigidity.1 Experimental and clinical data point to a chronic effect on the kidneys following long-term fluoride ingestion.Most thoroughly documented is an increase in the function of the

The Removal of Fluoride From Waters by Adsorption

p,p'DDE generally accounts for 60-70% of the total chlorinated hydrocarbon content in sediment, whereas PCB's (mostly Arochlor 1254) constitute almost 10-20% of the total. Other isomers of DDT and dieldrin account for the remaining fraction. Concentrations of chlorinated hydrocarbons are closely related to the organic contents and to particles of 8 gm or less in size. Total organic carbons of sediments as well as fulvic and humic acid fractions bear a linear relationship with respect to concentrations of chlorinated hydrocarbons in sediments. Total chlorinated hydrocarbon contents of sediments studied range from 0.3 to 3.5 ppm, whereas total organic carbon contents range from 0.45 to 1.70% on a dry weight basis.

Associations of chlorinated hydrocarbons with fine particles and humic substances in nearshore surficial sediments

In the present study, an improved curcumin method has been developed using a 20 percent v/v 2-ethyl-l, 3-hexanediol, a boron complexing agent, in methyl isobutyl ketone as an extracting solvent. A 5-cm cylindrical quartz cell is
