Since the 1970s, acid rain has remained in the public spotlight in both Europe and the United States and recently has emerged as an important problem in other regions such as Southeast Asia. To reveal responses of Masson Pine to acid rain during a long time series in central China, we used the interpolation dataset of acid rain and the Global Inventory Modeling and Mapping Studies (GIMMS) norma...
A laboratory experiment was performed to examine the impact of simulated acid rain (SAR) on nutrient leaching, microbial biomass, and microbial activities in a lateritic red soil in South China. The soil column leaching experiment was conducted over a 60-day period with the following six SAR pH treatments (levels): 2.5, 3.0, 3.5, 4.0, 4.5, and 5.0 and one control treatment (pH = 7). Compared wi...
The objective of this paper is to identify strategies for the U S electric utility industry for reduction of both acid rain producing and global warming gasses The research used the EPRI Electric Generation Expansion Analysis System (EGEAS) utility optimization / simulation modeling structure and the EPRI developed regional utilities It focuses on the North East and East Central region of the U...
Anthropogenic pollution causes oxidative stress in plants and reactive oxygen species (ROS) are diminished by antioxidative enzymes and small molecular antioxidants. Pollution may also affect the performance of plant-eating animals by increasing or decreasing their performance. The effects of pollution cannot be fully understood without knowledge of how pollution affects the interactions with t...
Leaching of metals from cement under various environmental conditions was measured to evaluate their environmental safety. A cement product containing clinker, which was produced from cement kiln co-processing of hazardous wastes, was solidified and leaching of metals was characterized using the 8-period test. Concentrations and speciation of metals in cements were determined. Effects of ambien...
Acid rain (AR) is a serious global environmental issue causing physio-morphological changes in plants. Melatonin, as an indoleamine molecule, has been known to mediate many physiological processes in plants under different kinds of environmental stress. However, the role of melatonin in acid rain stress tolerance remains inexpressible. This study investigated the possible role of melatonin on d...
The effects of artificially applied acid rain on functional activity of PS2 and oxygen evolution of bean plants (Phaseolus vulgaris L.) were investigated. The plants were subjected to single treatment with acid rain of different pH – pH 5.6 (control) and 2.4, 2.2, 2.0 and 1.8. Measurements were carried out in dynamics – at time intervals of 3–168 hours. The results showed that the treatment of ...
