Pune: In one of the biggest independent studies of its kind, city-based Indian Institute of Tropical Meteorology (IITM) and researchers from the UK concluded that there had been little growth in India's methane emission rate over the last few years. The study, which was recently published in Nature Communications, found …
Agro wastes such as carrot peel, onion peel, potato peel and sugar beet peel are products subjected to saccharification process by Penicillium sp. for the hydrolysis, this process was followed by the fermentation using yeast Saccharomyces cerevisiae for the production of alcohol which was fermented at 14, 21, 28 days …
Hydrocarbons are key precursors to two priority air pollutants, ozone and particulate matter. Those with two to seven carbons have historically been straightforward to observe and have been successfully reduced in many developed cities through air quality policy interventions. Longer chain hydrocarbons released from diesel vehicles are not considered explicitly …
Keoladeo National Park (KNP) is an important wintering ground for thousands of birds that undertake a perilous journey over the Himalaya to make a seasonal home in a wetland ecosystem. However, this wetland is now getting polluted by various types of contaminants such as pesticides because of the agricultural practices …
This document contains the presentation by D. V. Borole, NIO Goa, on dynamics of trace gases at low level planetary boundary layer observed at Cabo de Rama, west coast of India, presented at National climate research conference, IIT Delhi, March 5-6, 2010. Atmospheric gases are considered to modulate the global …
Due to reported detrimental health effects of diets high in trans fatty acids (TFA) in particular on blood lipids, convenience products, trade margarines, fats for cooking and frying and fast food products available on the Austrian market were comprehensively investigated on TFA, using gas chromatography.
Polycyclic Aromatic Hydrocarbons (PAHs) are a class of organic pollutants that are commonly found in the environment, largely due to combustion or processing of hydrocarbon fuels. With increasing awareness that PAHs are known and suspected carcinogens, this study was undertaken to monitor PAH compounds in Total Suspended Particulate Matter (TSPM) …
A solid phase extraction and gas chromatography with negative chemical ionization mass spectrometry in scan mode (GC-NCI-MS) method was developed to identify and quantify for the first time low levels of organochlorine pesticides (OCs) in plasma samples of less than 100 ?l from wild birds. The method detection limits ranged …
In Poland honey has never been included in regular pesticide residues controls. Because no maximum residues levels (MRLs) have been established for pesticides in honey it is very hard to evaluate the contamination of honey with pesticides and the possible damage to human health. This study was carried out in …
Baby bottles are often made of polycarbonate plastic. Impurities remaining in the bottle from the monomer bisphenol A can migrate from the plastic bottles into baby food, thereby causing a health concern. Previous migration testing of new baby bottles showed only trace migration levels of the substance. In the present …
This study was undertaken to access the residue of commonly used pesticides viz Cypermethrin, Methamedophos, Monocrotophos, Cyfluthrin, Dialdrin and Methyl Parathian respectively in three varieties of mano being collected from the grower fields in Multan division. The samples were treated with organic advent Cyclohexane and ethylacetate (1:1), cleaned on Gel …
In this study, a new clean up method was developed for the routine multiresidue determination of organochlorine pesticide residues in honey. The analytical procedure requires sample extraction with methanol, followed by a clean up step through a C18 Sep-Pak cartridge. Finally, pesticides are eluted with hexane. The determination of organochlorine …
