Assessing the feasibility of land application of fly ash, sewage sludge and their mixtures

Land disposal of fly ash (FA) and sewage sludge (SS) is a major problem due largely to their potentially harmful constituents. Combined use of FA and SS however may help reduce the associated pollution potential. In this paper we summarize the results of several case studies designed to assess the feasibility of land application of FA with and without SS. A wide range of application rates was tested under laboratory, greenhouse and field conditions. The leaching of metals from soil columns amended with moderate rates of FA applications (8-16 Mg ha⁻¹) generally had no significant impact on the metal content of leachate or their downward migration in the soil. The application of FA or SS at a much high rate (74.1 Mg ha⁻¹) significantly increased both leaching and downward migration of metals. The use of 1:1 FA+SS mixture at 148.2 Mg ha⁻¹ reduced metal leaching compared to the combined metal quantities leached when FA or SS applied at 74.1 Mg ha⁻¹. The results indicate that combined use of FA and SS at a rational rate of application should not cause any significant effect on drainage water quality. Plant studies conducted using FA and SS mixtures indicated that these materials could be beneficial for biomass production, without contributing significant metal uptake or leaching. The application of FA as high as 560 Mg ha⁻¹ in a long-term field trial had no detectable deterioration in soil or groundwater quality and no substantial increases in plant uptake of metals and other trace elements were observed. Low to moderate rates of FA and SS therefore could be successfully used as soil amendments, particularly so when used as a mixture.

广东近海水域重金属含量及其分布规律的研究

广东近海水域重金属含量由陆向海方向,随海水盐度、pH值升高及化学耗氧量降低而降低。重金属与环境要素相关的密切程度不仅取决于它们在水体中的迁移形态和化学性质,而且还受到环境理化要素变化的制约。各种重金属元素与水体中有机物的相关程度顺序为:Cu>Zn>Pb>Cr>Hg>As。对影响海水重金属含量及其变化规律的几个主要外界影响因素进行了讨论。

Modern sea level changes of the Eastern China Seas and their influences on coastal areas

The statistics of tidal gauging records showed that the mean sea level of the China Seas has risen for 14 cm in past 100 years. The annual mean sea levels of the Eastern China Seas have been rising at a speed of about 0.21 -0.23 cm/a since 1960. The annual mean sea levels of the Eastern China Seas in 1989 were 1.45 cm higher than that in 1988 on average.The sea level rise may cause the damage of the dynamical balance of the natural environments in the coastal area? and form or strengthen many coastal disasters, such as storm-tide catastrophic events, sea water invasion landward, soil salinization in coastal lowland and plains, and beach erosion retreat.
