Herbicides are the main type of pesticides causing water contamination. The chloroacetanilide herbicide Smetolachlor is frequently detected in ground and surface waters, and represents a potential source of water pollution. The addition of organic residues to soils to reduce losses of organic pollutants constitutes sometimes an efficient method to control contamination. One of the recent techno...

Understanding longitudinal trends in the processing of carbon in rivers represents a much conceptualised, but infrequently tested, issue in aquatic ecology. In this study, we conducted concurrent longitudinal examinations of three very different rivers in eastern Australia to determine whether general principles in river functioning exist across broad geographic and hydrologic scales. Specifica...

this research with the aims of microbial flora determination in pasteurized milk and it’s shelf life study based on microbial and physicochemical parameters were performed within 10 days. in this study, 60 pasteurized milk samples randomly were selected and then total count of bacteria and total psychrophilic bacteria count were performed. to investigate microbial flora of pasteurized milk, col...

Public health is at risk from physical and chemical contaminants in the drinking water which may have immediate health consequences. The data from the current study was evaluated for groundwater quality in the rural villages of Neyshabur County in Iran. For determination of the essential physicochemical parameters, water samples were collected from 30 randomly-selected water wells during 2013 a...

Persea macrantha (Nees) Kosterm (Lauraceae) is an important traditional medicinal plant being used for treatment of asthma and rheumatism. Systematic pharmacognostical evaluation of bark of the plant has been carried out with respect to macroscopy, microscopy, physicochemical parameters and estimation of different standards. TLC profiles were developed for petroleum ether and chloroform extract...
