Male Chinese hamsters were exposed to diesel exhaust and clean air for six months at the Center Hill Facility of the U.S. Environmental Protection Agency in Cincinnati, Ohio. The animals were kept in specially constructed inhalation chambers and exposed to clean air or diesel exhaust for eight hours daily. The animals were sacrificed and slides prepared to study the mutagenic effects of diesel exhaust by four in vivo short term mammalian bioassays. Sperm morphology bioassay revealed a 2.67-fold increase in sperm abnormalities in the animals exposed to diesel exhaust as compared to those exposed to fresh air. Micronucleus bioassay revealed a 50% increase in the number of micronuclei in polychromatic erythrocytes obtained from animals exposed to diesel exhuast. However, no increase in sister chromatid exchange or chromosomal abnormalities was observed in bone marrow cells of animals treated with diesel exhaust. During these studies a decrease in mitotic index was observed in animals treated with diesel exhaust. 相似文献

Oxidative stress inducing potential of fly ash leachate (FAL) was studied in a freshwater fish, Channa punctata (Bloch). Fish were exposed to fly ash leachate for 24 h and lipid peroxidation (LPO) was studied as a marker of oxidative stress. Catalase (CAT), glutathione S-transferase (GST) activities and levels of reduced glutathione (GSH) were also estimated in the exposed fish. FAL (1 ml/l) induced LPO in all the organs and most prominent response was in the gill. It also caused induction of enzymes and glutathione. Liver showed highest level of induction of enzyme activities. The results of this study demonstrate that fly ash constituents have potential to induce oxidative stress in fish and gills are the most vulnerable organs. It is also suggested that in case of exposure to FAL, along with LPO antioxidant defense is also activated to counteract the reactive oxygen species (ROS) at least partly in the initial stages of exposure. 相似文献

The present investigation was an attempt to compare the within-watershed prioritization capabilities of a physical model based SDSS with the SYI and RPI model based subjective-SDSS, conventionally devised for between-watershed prioritizations, by All India Soil Survey and Land Use Planning Division of Ministry of Agriculture, Government of India. Application of these two approaches on a test watershed situated in Damodar-Barakar catchment in India, the second most seriously eroded area in the world, demonstrated that the proposed physical model based SDSS was capable of realistically and logically mimicking the sub-watershed-scaled water and soil losses thereby suggesting its immense application potential for priority area identification within the test watershed. In contrast to the proposed physical method, the subjective approaches, which assigned totally reverse priorities to about 67–93% of the test-sub-watersheds, were observed to be incapable of realistically assessing the impact of topography and varied land use and soil types in the test watershed on their sub-watershed scaled run-off and soil loss generating potential. Besides, the physical approach could be used for assessing the annual dynamics of the total water and sediment yields, under prevailing resource management systems in the test watershed with good to moderately good correlation coefficients of 0.83 and 0.65; model efficiency coefficients of 0.54 and 0.70; mean relative errors of –4.28% and –17.97% and root mean square prediction errors of 71.8 mm and 9.63 t/ha, respectively. 相似文献

The impact of 2,4-D ethyl ester and pencycuron in inducing DNA damage in three species of cyanobacteria-Anabaena fertilissima, Aulosira fertilissima, and Westiellopsis prolifica as evidenced by PCR-based assays: RAPD and 16S rRNA amplification was examined. Exposure of genomic DNA (in vitro) to pencycuron for 4 days did not produce severe damage in DNA fragments of all three cyanobacterial species whereas exposure to 2,4-D ethyl ester markedly inhibited the template activity of genomic DNA compared to untreated cultures of A. fertilissima. In A. fertilissima a single band of approximately 1000?bp was observed even after 16 days of exposure to 60?ppm pencycuron which suggests that certain segments of DNA are resistant to pencycuron DNA damaging effects. However, a significant effect was observed in the case of W. prolifica for 2,4-D ethyl ester and pencycuron where complete disappearance of fragments was not recorded even after 16 days of incubation and interestingly some new DNA bands were induced. Similar to the effects with RAPD profile, amplification of rRNA was significantly inhibited following exposure of genomic DNA to 2,4-D ethyl ester and pencycuron. Our findings clearly demonstrate that pesticide concentrations affected cyanobacterial DNA and lethality of these microbes might be due to irreversible DNA damage. Thus, it is postulated that PCR assays may be conveniently used for screening DNA damage produced by 2,4-D ethyl ester and pencycuron in all three cyanobacteria examined in this study. 相似文献

Radon concentration was measured in water samples of 41 different locations from Udhampur district of Jammu & Kashmir, India, by using RAD7 and Smart RnDuo monitor. The variation of radon concentration in water ranged from 1.44 ± 0.31 to 63.64 ± 2.88 Bq L?1, with a mean value of 28.73 Bq L?1 using RAD7 and 0.64 ± 0.28 to 52.65 ± 2.50 Bq L?1, with a mean value of 20.30 Bq L?1 using Smart RnDuo monitor, respectively. About 17.07% of the studied water samples recorded to display elevated radon concentration above the reference range suggested by United Nation Scientific Committee on the Effects of Atomic Radiations (UNSCEAR). The mean annual effective dose of these samples was determined, and 78.95% samples were found to be within the safe limits set by World Health Organisation (WHO) and European Council (EU). The study revealed good agreement between the values obtained with two methods. Heavy metals (Zn, Cd, Fe, Cu, Ni, As, Hg, Co, Pb and Cr) were determined in water samples by microwave plasma atomic emission spectrometer, and their correlation with radon content was also analysed. 相似文献
