Some insects of economic importance from Lucknow (India) have been investigated for their pesticide burden. Chlorinated pesticide residues of DDT, BHC and aldrin along with their metabolites and isomers have been detected in crop pollinating insects, honeybees (Apis indica) and butterflies (Danais chrysippus and Eurema sp.) and predators, dragonfly (Platythemis sp.) and wasps (Polistes herebreus). DDT and their metabolites were present in concentrations which varied from 231–796 ng g–1, followed by BHC (10–60 ng g–1), and aldrin (0.26–6.68 ng g–1). This finding is likely to stimulate newer interest in the area of pesticide research and start meaningful investigation to find if bioaccumulated pesticides would have adverse impact on otherwise beneficial potentials of such insects in our ecosystems. 相似文献

The present work was conducted to define the magnitude of the problem of heat exposure in Jeddah and the role of both the climatic and the industrial factors on the total heat load. Indoor heat exposure was studied in an industrial complex of 5 plants for cables' manufacturing. Outdoor heat exposure was studied in shaded and unshaded operations in Jeddah Islamic Port (JIP). The heat exposure parameters, including air temperature (Ta), wet bulb temperature (Tw), and globe temperature (Tg), as well as the wet bulb globe temperature (WBGT) heat stress index, the relative humidity and the air velocity, were assessed at representative locations. Results of the study indicated that:
An outline of a control strategy has been suggested, emphasizing evaporative engineering heat control, work and hygienic practices and auxiliary cooling clothing. 相似文献
(a) | the levels of heat exposure exceeded the TLV in mostly all the work areas where no air-conditioning is provided. |
(b) | the ambient heat is the factor contributing most to the heat load both in summer and in winter. |
(c) | the radiant heat from furnaces and hot metal rolling and milling adds more heat load to the work environment in specific operations. |

Role of plant growth promoting rhizobacteria in the remediation of metal contaminated soils 总被引:2,自引:0,他引:2

Pollution of the biosphere by the toxic metals is a global threat that has accelerated dramatically since the beginning of
industrial revolution. The primary source of this pollution includes the industrial operations such as mining, smelting, metal
forging, combustion of fossil fuels and sewage sludge application in agronomic practices. The metals released from these sources
accumulate in soil and in turn, adversely affect the microbial population density and physico-chemical properties of soils,
leading to the loss of soil fertility and yield of crops. The heavy metals in general cannot be biologically degraded to more
or less toxic products and hence, persist in the environment. Conventional methods used for metal detoxification produce large
quantities of toxic products and are cost-effective. The advent of bioremediation technology has provided an alternative to
conventional methods for remediating the metal-poisoned soils. In metal-contaminated soils, the natural role of metal-tolerant
plant growth promoting rhizobacteria in maintaining soil fertility is more important than in conventional agriculture, where
greater use of agrochemicals minimize their significance. Besides their role in metal detoxification/removal, rhizobacteria
also promote the growth of plants by other mechanisms such as production of growth promoting substances and siderophores.
Phytoremediation is another emerging low-cost in situ technology employed to remove pollutants from the contaminated soils.
The efficiency of phytoremediation can be enhanced by the judicious and careful application of appropriate heavy-metal tolerant,
plant growth promoting rhizobacteria including symbiotic nitrogen-fixing organisms. This review presents the results of studies
on the recent developments in the utilization of plant growth promoting rhizobacteria for direct application in soils contaminated
with heavy metals under a wide range of agro-ecological conditions with a view to restore contaminated soils and consequently,
promote crop productivity in metal-polluted soils across the globe and their significance in phytoremediation. 相似文献

This study investigates the production of organic fertilizer using Anaerobic Digestate (as a nutrient source) and limestone powder as the raw materials. A two-level factorial experimental design was used to determine the influence of process variables on the nutrient homogeneity within the granules. Increasing the liquid-to-solid ratio during granulation resulted in increased granule nutrient homogeneity. Increasing the processing time and the impeller speed were also found to increase the nutrient homogeneity. In terms of nutrients release into deionized water, the granules effectively released both potassium and phosphate into solution. 相似文献

The porous composites of clay and fly ash have the potential to be used in many fields, such as catalyst support and gas adsorbents. In this study, various ratios of fly ash (1–2) with different percentage of suspension (50–70 wt%) were applied to produce porous clay-fly ash composites via polymeric replica technique. Fabrication process starts by mixing clay and fly ash in distilled water to form slurry. The process is followed by fully immersing polymer sponge in slurry. The excess slurry is then removed through squeezing. Finally, the sponge coated with slurry is sintered at 500 and 1250 °C for 1 h. It is found that the compressive strength of porous composites improves significantly (0.178–1.28 MPa) when the amount of clay-fly ash suspension mixture (50–70 wt%) increases. The compressive strength of porous composites is mainly attributed to the mullite, quartz and amorphous phase formations. These results are supported by X-ray diffraction analysis. On the other hand, increase in the amount of suspension reduces the apparent density (from 2.44 to 2.32 g/cm3) and porosity (from 97 to 85 %). The reduction in apparent density is believed to be caused by the presence of high fly ash content in porous composites. The melted fly ash cenospheres have closed the internal pores and increased density of samples. Higher suspension level not only reduces porosity, but also increases close pores of the porous composites. The results are justified through the observation from the structures of porous clay-fly ash composites. 相似文献
