After a decade of deliberations and review of more than 1,700 new studies, the U.S. Environmental Protection Agency (EPA) announced the new primary standard for ground-level ozone in March 2008. The new standard, 75 ppb, is being assailed from all sides

The effects of an insecticide monocrotophos on some biochemical parameters of the fish, Tilapia mossambica at 24, 48, 72 and 96 hrs of exposures were studied. Median lethal concentration of monocrotophos to the fish for 24 hour exposure was determined during bioassay study. The protein contents were found to be declined in all the samples analyzed during all the exposure periods.

This paper presents, result of laboratory experiments for the recovery of alum from sludge obtained from tertiary treatment of effluent collected from waste stabilization pond after grab sampling. The study was conducted on wastewater from a stabilization pond having capacity of 54 mld, which was treating municipal wastewater from Ujjain city.

Robust growth rate in the automobile components sector and pressure on component suppliers to demonstrate environmental performance along with quality, cost and delivery make small and medium scale automobile ancillary component suppliers in the need of addressing their environmental issues and and waste minimisation options in their industry.

The sloth bear is a Schedule 1 species in the Indian Wildlife Protection Act, 1972, and has been listed as "threatened" by IUCN. No systematic information is available on sloth bear distribution and population either in or outside the protected areas in India.

In 2005, months of unprecedented higher-than-normal water temperatures started a cascade of bleaching, disease, and death among corals in the Eastern Caribbean. Such events are increasing in frequency around the world and threaten these fragile ecosystems, which shelter a wealth of biodiversity and provide sources of food and pharmaceuticals. Researchers must determine how rising temperatures produce coral bleaching, the pathogens that cause disease in corals, and the environmental factors that foster disease outbreaks.

Biomass fuel is the primary source of domestic fuel in much of rural China. Previous studies have not characterized particle exposure through time

Bambusa tulda (Deobans), a symbodial bamboo species, grows well in humid tropical and sub-tropical regions of the Indian sub continent. In India it is distributed naturally in the North and North-eastern parts of the country. It produces culms up to 10-15 m height and 4-8 cm dia. Flowering is reported generally after 25-30 years.

The removal of chromium (VI) from synthetic wastewater by adsorption on activated carbon prepared from Royal Poinciana shell was tried to determine the effects of different dosages and different pH.

In the present paper an attempt has been made to study the waste management strategies of textile industries in general and bleaching and dying industry in particular and suggest techno-economical line of treatment of the same. The TDS, chlorides and sulphates are the matter of concern in the treated effluent.
