The objective of the study examines the impact of industrialization and financial development on water resources, in the specific context of Pakistan. Data set from 19752009 are taken for time series analysis. The result reveals that economic growth positively linked with the water resource, as water plays a pivotal role in the economic development of a country. Thus limiting this resource woul...

BACKGROUND The deposition of cannabinoids on/into hair from environmental smoke can be considered as a potential source of drug findings in hair. We studied external uptake of cannabinoids from marijuana smoke, investigating possible influencing factors on drug uptake and the efficiency of decontamination procedures. METHODS Strands of a natural hair sample were moistened with water, greased ...

PCR is the best method for the detection of enteric viruses present at low concentrations in environmental samples. However, some organic and inorganic compounds present in these samples can interfere in the reaction. Many of these substances are cytotoxic, too. The ZP60S filter membranes used in addition to fluorpentane treatment are quite efficient for virus concentration and simultaneous eli...

Water resource crises are an increasing threat to human survival and development. To reveal the nature of water resource issues under changing situations, the water resources system needs to be studied from a macro and systematic perspective. This report develops a water resources system into a water resources compound system that is constantly evolving under the combined action of the developm...

The present research is aimed at establishing how farmers can be encouraged to adopt irrigation water saving measures. By developing and implementing an extended version of the well-known Theory of Planned Behavior, we considered farmers’ propensity to adopt innovations and their water footprints. In a sample of 150 Italian farmers, we found that favorable attitudes towards water saving measure...

lead, copper, cobalt, nickel, iron and zinc ions form monocitrate complexes (negative charge) in citrate solution which is absorbed on the citrate form of anion-exchange resins (citrate as counter ion) y exchange of citrate ion with citrate complexes. these are subsequently recovered from the resin by 0.5m ammonium citrate eluent at ph 2.0. under optimized conditions, quantitative recovery was ...

the dispersive liquid–liquid microextraction (dllme) method for determination of pb +2 and cd +2 ions in the environmental water samples was combined with inductively coupled plasma-atomic emission spectrometry (icp-aes). ammonium pyrrolidine dithiocarbamate (apdc), chloroform and ethanol were used as chelating agent, extraction solvent and disperser solvent, respectively. some effective parame...

A simple in situ visual and tristimulus colorimetric method for the determination of trace arsenic in environmental water after collecting arsenic on a test paper impregnated with mercury(II) bromide and rosaniline chloride by its reduction aeration has been developed. The color development on the test paper is based on the formations of AsH(HgBr)2 (yellow) and/or As(HgBr)3 (brownish yellow) by...

in the present work a modified in-tube solid phase microextraction technique followed by gas chromatography-mass spectrometry (gc-ms) has been applied for determination of water odorants. geosmin, 2-methyl isoborneol, 2-isopropyl-3-methoxy pyrazine, 2-isobutyl-3-methoxy pyrazine and 2,4,6-trichloroanisol are of the most important odorants which have been studied. in the described method, analyt...
