Eutrophic gradient in the Dal lake, Kashmir

On the basis of hydrochemical and biological studies, a trophic gradient has been established between the inshore and the offshore areas of the Dal lake. The inshore areas receive large quantities of raw sewage and agricultural runoff as a result of which high nutrient concentration of water and the presence of dense phytoplankton populations have been registered at these sites.

The four recent major earthquakes of the Himalayan Convergence Zone, viz., the Kangra earthquake of 1905, the Bihar-Nepal earthquake of 1934, and the two Assam earthquakes of 1897 and 1950 were assigned magnitudes greater than 8 by Richter. Although estimates of areas vary, it is agreed that an extended rupture with its long dimension parallel to the local strike of the Himalaya was involved in each case.

Quantitative assessment of worldwide contamination of air, water and soils by trace metals

Submitted by susan on Mon, 2012-09-24 10:26

Calculated loading rates of trace metals into the three environmental compartments demonstrate that human activities now have major impacts on the global and regional cycles of most of the trace elements. There is significant contamination of freshwater resources and an accelerating accumulation of toxic metals in the human food chain.

A hydro-wood net-energy approach to hydro project design

An integrated approach to energy planning, when applied to large hydroelectric projects, requires that the energy-opportunity cost of the land submerged under the reservoir be incorporated into the planning methodology.

Determination of arsenic in whole blood by graphite platform-in-furnace atomic absorption spectrometry with nitric acid de-proteinisation and nickel fortification

Submitted by susan on Tue, 2012-07-24 12:15

The effect on the charring temperature of arsenic in blood with wall and platform atomisations of a number of matrix modifiers, such as cobalt, copper, nickel and palladium, has been studied. Based on this study, a nitric acid de-proteinisation-nickel matrix modification-graphite platform-in-furnace atomic absorption spectrometric method was developed for the determination of nanogram per millilitre levels of arsenic in whole blood samples after a systematic evaluation of the temperature programme of the atomiser. The method of standard additions is mandatory.
