A Simulation of the Interaction of Acid Rain with Soil Minerals
Journal of Chemical Education, 2004The environmental issue of acid rain is incorporated into a five-part laboratory project that employs quantitative analytical laboratory techniques, such as acid–base titrations and gravimetric analysis of aqueous cations. The student observes the effectiveness of soil at consuming excess acidity in rainwater and observes the mobilization of Al3+ and ...

Response of Quercus acutissima foliage to different types of simulated acid rain
, 2021The harm of acid rain (AR) to plants foliage is mainly manifested by changing their physiological and biochemical processes, such as chlorosis, nutrient loss, enzyme activity changes, etc., which in turn impacts plant growth.

Hexavalent chromium, Cr(VI), is a ubiquitous toxic metal that can be reduced to Cr(III) by nano-zero-valent iron (nZVI). Finding out effects of continuous rainfall leaching on the Cr(VI) release and availability remains a problem, needing to be addressed.

Simulated acid rain effects on acidification of a Lexington silt loam
Water, Air, & Soil Pollution, 1986Intact soil cores were collected to a depth of 15 cm from a Lexington silt loam. Simulated precipitation with adjusted pH values of 3.7, 4.7 and 5.7 (control), was applied to the cores in increments of 500 mL day until totals which approximated 10, 20, 40, and 80 yr of effective rainfall in Louisiana were reached.

Simulated acid rain affects birch leaf endophyte populations
Microbial Ecology, 1993Endophytes were frequently isolated from mountain birch (Betula pubescens var. tortuosa (Ledeb.) Nyman) leaves at a subarctic site where natural air pollution is low. We tested whether simulated acid rain had any influence on the occurrence of endophytes.

Activity of Earthworm in Latosol Under Simulated Acid Rain Stress
Bulletin of Environmental Contamination and Toxicology, 2014Acid rain is still an issue of environmental concerns. This study investigated the impacts of simulated acid rain (SAR) upon earthworm activity from the Latosol (acidic red soil). Laboratory experiment was performed by leaching the soil columns grown with earthworms (Eisenia fetida) at the SAR pH levels ranged from 2.0 to 6.5 over a 34-day period ...

Impacts of simulated acid rain on recalcitrance of two different soils
Environmental Science and Pollution Research, 2012Laboratory experiments were conducted to estimate the impacts of simulated acid rain (SAR) on recalcitrance in a Plinthudult and a Paleudalfs soil in south China, which were a variable and a permanent charge soil, respectively. Simulated acid rains were prepared at pH 2.0, 3.5, 5.0, and 6.0, by additions of different volumes of H2SO4 plus HNO3 at a ...

Effects of simulated acid rain on the photosynthetic physiology of Acer ginnala seedlings
, 2021Extensive areas in China have been receiving high levels of acid rain. Acid rain affects plant growth by reducing the chlorophyll content, destroying leaf structure, and hindering photosynthesis.
