With iron oxide nanoparticles The millions of arsenic victims living in Bangladesh and India have another option for obtaining clean drinking water. Finely divided iron oxide nanoparticles (ionps) can remove arsenic from contaminated water. Iron-containing compounds have been used in purifying groundwater. By the property of adsorption, arsenic can bind to the solid surface of iron.
Untreated sewage water for irrigation affects soil untreated sewage water-fed farming is considered cost-effective. But this solution comes at a cost. Such sewage water contains heavy metals that harm the soil fertility. A study showed that the heavy metals affect soil in two ways. One, they hinder the activities of micro-organisms that help recycle nutrients and aid in plant
Here is some good news for the flood victims. They need not consume polluted water as they used to for days together when their drinking water sources remained submerged in floods.
a research team has stumbled upon a bug that feasts on arsenic. Present in the root nodules of black gram, the bacteria increases soil fertility and fixes nitrogen. It could be an effective way of bioremediation of arsenic from contaminated soil, says a team of researchers from iit Kharagpur and Vidyasagar University, Midnapore, West Bengal. They isolated a tolearant strain of rhizobium
Long-term impacts of drinking chlorinated water on the incidence of cancers and miscarriages were assessed in a population-based cross sectional study conducted in the two campus communities of IIT Kanpur (IITK) and IIT Kharagpur (IITKgp). IITK has been using untreated groundwater since the community was established in 1963, while IITKgp has been using chlorinated water for more than 30 years.
sericin, a by-product of silk, may now find use in skin care products that protect from ultraviolet (uv) rays. A study revealed the protein protects the outermost layer of skin from uv rays.
Weekly variations in free and total chlorine residuals and their impact on microbial concentrations were monitored for the IIT Kharagpur water supply to determine possible correlations between heterotrophic bacterial density, total and faecal coliform density, and total and free chlorine residuals.
BHUBANESWAR: Orissa already among top investment destinations, the State Pollution Control Board (SPCB) has chalked out plans which will give industries a regulatory frame-work that is responsive, efficient, equipped with a sound enforcement mechanism and scientific at the same time.
The pollution watchdog of the State has already stitched up plans for the future by readying its Vision-2030 wh
