Solid waste management practices in the Eastern Province of Saudi Arabia are reviewed. The officials of various municipalities and agencies responsible for collecting and disposing of municipal waste were interviewed. The refuse generation rate found is in the range of 1.61–2.72 kg per capita per day. The refuse composition data indicate a high percentage of glass, metals, and wood. For storage purposes, 0.2-m3 barrels are used in residential areas and 0.75 to 1.50 m3-capacity containers are used in commerical areas. The present solid-waste collection system is labor-intensive, and a significant part of the budget is spent on collection and haul operations. The unit collection and haul cost is much higher than the unit disposal cost of refuse. The direct haul of refuse is the common practice, and the use of transfer stations has not yet been considered. It is also observed that the disposal methods used at these sites are not in line with modern techniques for refuse disposal. Landfilling and combined burning and landfilling are the common disposal methods at all the sites. 相似文献

Determination of solid-bound element concentrations is an important initial step in environmental studies especially for assessment of contamination level, and of origin, relative mobility, and fate of contaminants. This study revealed that a relatively new collision/reaction cell inductively coupled plasma-mass spectrometry is a potent tool for determining total and partially extractable solid-bound element (V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, and Pb) concentrations in a complex matrix solution containing HF and/or HCl. Six different extraction methods commonly used for environmental monitoring studies were tested for their bias and variability using estuarine and marine standard reference materials. Microwave-assisted methods based on concentrated [HNO3] or [HNO3?+?HF (4:1)] and [HNO3?+?HF?+?HCl (10:3:2)] were applied for determining pseudo-total and total element concentrations, respectively. Dilute-acids (1 M HNO3, 1 M HCl, and 0.5 M HCl) were utilized in single-step partial extraction protocols. Except the 0.5 M HCl cold-extraction method which was performed at room temperature, other partial extraction protocols used microwave-digestion. This study demonstrated that the use of microwave-assisted methods in studies aimed at determining the non-residual, non-specific extractable fractions of elements in solid environmental samples may result in overestimation, and thus needs to be re-examined. We believe that the cold extraction method will play a significant role in future environmental monitoring studies. Nevertheless, results of the cold extraction method not accompanied with total element concentrations have limited value, as the amount of extraction may vary significantly with the nature (origin) of the elements, and with the types of the samples. Therefore, we suggest combining microwave-assisted total digestion and 0.5 M HCl cold-extraction methods as a relatively cost- and time-effective, environmentally sound screening procedure for routine environmental monitoring programs involving a large number of samples from diverse geological and anthropogenic settings. 相似文献

Activities of 210Po and 210Pb in various tissues of four species of decapod crabs and two species of cephalopod mollusks (cuttlefishes) of Kudankulam coast were studied. A non-uniform distribution of these radionuclides was observed between the organs. Of all the tissues, 210Po and 210Pb were found accumulated more in the hepatopancreas and intestine of crabs and in the digestive gland, shell gland, and intestine of cephalopods. Among crabs, Charybdis lucifera registered a little higher 210Po and 210Pb activities. The cephalopod species Loligo duvauceli displayed higher 210Po and 210Pb in some organs when compared to Sepia pharaonis. The muscle of all the species registered lower activity. In cephalopods, the activity ratio of 210Po/210Pb fell within the range of 1?C2 for most of the organs, and in crab tissues, it varied from 1.7 to 31.4. The biological concentration factor for organs of cephalopods ranged from 1.2 ×103 to 4.3 ×105 for 210Po and 4.8 ×102 to 8.4 ×104 for 210Pb and for organs of crabs it varied between 2.0 ×104 and 1.9 ×106 for 210Po and 9.2 ×102 and 2.4 ×104 for 210Pb. The study revealed that the organs associated with digestion and metabolism displayed a higher activity concentration than the other tissues. A significant variation in the accumulation of 210Po and 210Pb was noted between species (P?<?0.05). The activity levels recorded are in agreement with values recorded in related organisms in other parts of the world. The data generated will act as a reference database for these organisms of this coast in which a nuclear power station is under construction. 相似文献
