本世纪初我国大陆7级大震危险性研究

地震大形势研究结果表明，我国大陆地区（含边境）１９９９年已进入为期１２年的相对平静幕，幕内可能发生３次７级地震，最大震级不超过７．２级。首发７级地震为２０００年６月８日缅甸７级（位于中缅边境）。预计第二个７级地震危险时间在２００５±０．５年。第三个在２００８年前后。分析了我国主要地震区强震概率增益，给出了３个危险地点。未来３年即２００１～２００３年是相对安全时段，我国大陆不会发生７级以上破坏性地震。２０１１～２０２０年可能进入新世纪第一个７级大地震相对活跃幕，预计该幕持续１０年， 可发生１０次７～７.６级大震。     

Distribution of heavy metals in marine bivalves, fish and coastal sediments in the Gulf and Gulf of Oman

An assessment of marine contamination due to heavy metals was made in the Gulf and Gulf of Oman based on marine biota (fish and various bivalves) and coastal sediment collected in Bahrain, Oman, Qatar, and the United Arab Emirates (UAE) during 2000-2001. Sediment metal loadings were generally not remarkable, although hot spots were noted in Bahrain (Cu, Hg, Pb, Zn) and on the east coast of the UAE (As, Co, Cr, Ni). Concentrations of As and Hg were typically low in sediments and the total Hg levels in top predator fish commonly consumed in the region were < 0.5 microg g(-1) and posed no threat to public health. Very high Cd concentrations (up to 195 microg g(-1)) in the liver of some fish from southern Oman may result from food-chain bioaccumulation of elevated Cd levels brought into the productive surface waters by upwelling in the region. Very high As concentrations (up to 156 microg g(-1)) were measured in certain bivalve species from the region. Although not certain, the As is probably derived from natural origins rather than anthropogenic contamination.     

Whole-bird models for the magnetic cleansing of oiled feathers

Iron powder, a promising dry-cleansing agent for oiled feathers where both the contaminant and the cleansing agent may be harvested magnetically, has been tested on the plumage of whole-bird models. The breast and back plumage of Mallard Duck (Anas platyrhynchos) and Little Penguin (Eudyptula minor) carcasses were patch-contaminated with commercial-grade engine oil, three different crude oils, and an oil/seawater emulsion. The plumage was then subjected to a magnetic cleansing protocol. The contaminant removal was assessed gravimetrically and was found to reflect the outcomes for a previously reported in vitro study using feather clusters. Between 92-98% of the contaminants, and effectively all of the cleansing agent, were removed from the feathers.     

预警等级预报--一种新的地震预报发布形式和对策的思考

本文回顾了我国地震预报发布形式的演变过程，分析了目前发布地震预报面临困境的主要原因。在分析了其他一些灾害的预警等级预报发布形式后，对地震预警等级预报发布的可行性和应当采取的对策进行了讨论，认为地震预警等级预报的发布，是实现真正意义上地震减灾的一种可行方法。最后提出了一些实施地震预警等级预报前仍需认真研究的问题。
