The Keelung port, which is located on the northern tip of Taiwan, right next to the Taipei metropolitan area, is an important
international harbor. However, any air pollutants generated from the Keelung port region, immediately travel to the neighboring
Keelung city, and greatly impact the residents' daily life and the quality of their environment. This study has investigated
and quantified pollution emissions, from the Keelung port region, between 1997 and 2002. Emissions from major air pollution
sources were estimated. The estimated results indicated that total TSP (total suspended particles) emissions had significantly
increased, from 5221 ton/yr in 1997 to 262 687 ton/yr in 2002, due to the greatly increased volume of sand imported into Keelung
Harbor. Quantities of other emissions, such as SO2, NO2, CO and HC remained stable and were 440, 207, 78 and 25 ton/yr, respectively, on average, with variations within 7% over
the previous six-year period. By examining the emissions from pollution sources, it was found that TSP emissions mainly originated
from re-suspension of dust, due to both vehicle movement and the sand unloading process; this accounted for over 99% of the
total TSP emissions produced in the port region. About 80% of the total SO2 emissions originated from the main ships' engines within the Keelung port region, due to the use of fuel with a high sulfur
content. In addition, loading/unloading machines within the port region were the major sources of NO2, CO and HC pollution emissions, which comprised 54, 58 and 66% of the total emissions of these pollutants, respectively.
TSP emissions from Keelung port were much higher than from the neighboring Keelung city; hence, alleviating TSP emissions
should be the first priority for air pollution reduction within both the port of Keelung and Keelung city. 相似文献

为模拟井下应力条件,设计固定轴压卸围压试验,得到煤样破裂过程的声发射结果,并计算不同初始围压及不同卸载速率条件下声发射时间序列的长程相关性特征,以期对煤岩体的破裂做出预警。研究结果表明:不同初始围压及不同卸载速率下声发射实验结果类似,根据声发射累计计数可将声发射变化过程分为线性增长期、平静期以及指数增长期,可以很好地反应煤样的破裂过程;随初始围压和卸载速率的增大,声发射时间序列的Hurst指数随之增大,正相关性增强;Hurst指数与分形维数的动态变化与煤样的失稳破裂过程良好对应,且不同初始围压及卸载速率下,Hurst指数与分形维数的动态变化规律类似,说明其声发射时间序列的宏观产生机制具有内在统一性,可将接近破裂荷载时Hurst指数的增大与分形维数的减小作为煤样失稳破裂的前兆信息。 相似文献
