The inhibition of seedling growth and nitrate reductase activity in 5 d old Vigna radiata (L.) Wilczek cv. Pusa Baisakhi in the presence of 1.0 mM lead acetate increased drastically, if NaCl (6 and 12 EC) was also present in the nutrient media along with the metal salt. Correspondingly higher endogenous Na+ levels were accumulated in the roots and leaves of seedlings in presence of the two stresses. On the other hand, the levels of endogenous lead get reduced in presence of NaCl in both the roots and leaves. Roots accumulated more Pb2+ and Na+ than the leaves. The two stresses affect more drastically in the additive or even synergistic manner during the early growth phase of the seedlings. 相似文献

The impact of graded concentrations (5, 10, 15 and 20 mg dm(-3) of acid mordant Metomega Chrome Orange GL, a common dye used in woollen, carpet and textile industries, was studied on protein and pigment content and photosynthetic oxygen evolution in a diazotrophic cyanobacterium Nostoc muscorum. The lower concentration of 5 mg dm(-3) showed a negligible effect on protein and pigment content and photosynthetic oxygen evolution, whereas at higher concentrations a drastic decrease in the above parameters was observed. The highest concentration of 20 mg dm(-3) resulted in a decrease of protein, chlorophyll a, phycocyanin and carotenoid content by 72, 76, 54 and 17% of the control, respectively. Photosynthetic oxygen evolution also decreased by 92% of the control at this concentration of the dye. 相似文献

This paper provides baseline information about the total annual dust fall, and its constituents and seasonal variation, from a sub-tropical opencast coalmine area in Bina, India. Dust samples were collected monthly for 2 years (June 2002-May 2004) from five sampling sites in the region and analyzed in the laboratory for water-soluble and -insoluble matter. Water-insoluble components constituted the major fraction of the total annual dust fall. Two-way ANOVA indicated significant variations in dust fall at different sites, over the months and in their interactions. The dust deposition rate was highest during summer (March-June), followed by winter (November-February) and lowest in the rainy season (July-October). Maximum dust fall was observed near the coal handling plant (at site 2) followed by the receiving pit of the coal handling plant (site 3), near the main sub-station (site 4), Jawahar colony (site 1) and Gharasari village (site 5). An inverse and significant relation was observed between dust fall and precipitation. Our studies have shown that the main residential areas are experiencing higher levels of dust fall which makes them unsuitable for living. We suggest that residential areas should be moved farther away from the mining area in the opposite direction of prevalent winds. 相似文献

The present investigation reports the assessment of hydrochemical/geochemical processes controlling the concentration of fluoride
in groundwater of a village in India (Boden block, Orissa). Boden block is one of the severely affected fluoride-contaminated
areas in the state of Orissa (India). The sampling and subsequent analysis of water samples of the study area was carried
out following standard prescribed methods. The results of the analysis indicate that 36.60% groundwater F− concentration exceeds the limit prescribed by the World Health Organization for drinking water. The rock interaction with
groundwater containing high concentration of HCO3− and Na+ at a higher pH value of the medium could be one of the important reasons for the release of F− from the aquatic matrix into groundwater. Geochemical classification of groundwater based on Chadha rectangular diagram shows
that most of the groundwater samples having fluoride concentration more than 1.5 mg L−1 belongs to the Na-K-HCO3 type. The saturation index values evaluated for the groundwater of the study area indicated that it is oversaturated with
respect to calcite, whereas the same is undersaturated with respect to fluorite content. The deficiency of calcium ion concentration
in the groundwater from calcite precipitation favors fluorite dissolution leading to excess of fluoride concentration. The
risk index was calculated as a function of fluoride level in drinking water and morbidity of fluorosis categorizes high risk
for villages of Amera and Karlakote panchayat of Boden block. 相似文献

A large amount of leather waste is generated from tanning industries and most of which are disposed of landfill or discharged into the natural water bodies without any treatment, causing environmental problems. The aim of this study is to develop eco-biocomposites using waste leather buff (WLB) as filler in Polylactic acid (PLA) matrix to reduce the environmental issues and provide sustainable solution. WLB/PLA composites were prepared by twins-screw micro extruder varying the WLB content from 2% to 30 wt%. These composite were extensively characterise by several techniques. Tensile properties of the composites showed addition of WLB resulted in improvement of tensile property of composite and reduction in percentage crystallinity of PLA matrix observed with increase in WLB content. The effect of WLB on properties of interfacial adhesion and dispersion in WLB/PLA composites were studied by SEM. Wettability of composites was tested by contact angle and water absorption studies. WLB/PLA composite showed increase in water absorption with WLB loading. These WLB/PLA composite could be used to develop low cost eco-friendly product material. 相似文献
