Effect of simulated acid rain on the stability of calcium carbonate immobilized by microbial carbonate precipitation.

Journal of Environmental Management, 2020
The stability of carbonate products resulting from microbially induced carbonate precipitation (MICP) under acid rain is under question. The present study investigated the stability of CaCO3 precipitated by MICP in soil under simulated acid rain (SAR ...

Responses of three wheat cultivars to simulated acid rain

Environmental and Experimental Botany, 1985
Abstract Seedlings of three wheat (Tritium aestivum L.) cultivars (Arthur 71, Abc and Oasis) were exposed to simulated rain acidified to pH 5.6, 4.3, 4.0, 3.3, 3.0, or 2.3 with sulfuric and nitric acids. The parameters measured included foliage weight, tiller number, and the number of leaves with more than 10% necrosis per pot.

Influence of Simulated Acidic Rain on Bacterial Speck of Tomato

Journal of Environmental Quality, 1984
AbstractAmbient rain in southern Ontario has a volume‐weighted average pH of approximately 4.2. Tomato (Lycopersicon esculentum Mill var. ‘Chico III’) seedlings were exposed to simulated acidic rain in specially designed chambers. The inoculum of Pseudomonas tomato (Okabe) Alstatt, causal agent of bacterial speck, was sprayed on plants before or after ...

Leaching characteristics of heavy metals in tailings and their simultaneous immobilization with triethylenetetramine functioned montmorillonite (TETA-Mt) against simulated acid rain.

Environmental Pollution, 2020
For further understanding leaching characteristics of heavy metals in tailings and better immobilization on heavy metals against acid rain, batch experiments were conducted.

Sensitivity of Twenty Soybean Cultivars to Simulated Acid Rain

Journal of Environmental Quality, 1990
AbstractEfforts to assess the effect of acid rain on soybean [Glycine max (L.) Merr.] have shown variable results. Simulated acid rain has been reported to cause increases, decreases, and no significant effect on yield. Although few parameters were identical among the diverse studies reported in the literature, one common difference was the choice of ...

Responses of loblolly pine to ozone and simulated acidic rain

Canadian Journal of Forest Research, 1996
Acidic rain and ozone (O3) may have serious consequences on the growth and development of loblolly pine (Pinustaeda L.), a tree species of major economic importance in the southeastern United States. In two independent studies, seedlings of open-pollinated families of loblolly pine were exposed to five concentrations of O3 (0, 80, 160, 240, or 320 nL ...

Effect of simulated acid rain on soil CO2, CH4 and N2O emissions and microbial communities in an agricultural soil

, 2020
Since the advent of industrialization and urbanization, acid rain has emerged as one of the quintessential global environmental issues. However, the effects of acid rain on carbon (C) and nitrogen (N) cycles of terrestrial ecosystems are still far from ...

Influence of ozone and simulated acidic rain on microorganisms in the rhizosphere of Sorghum

Environmental Pollution, 1988
Seedlings of a sorghum x sudangrass hybrid in pots of non-sterile soil-sand mix were exposed to ozone (O(3)) at 0, 0.15, or 0.30 microl litre(-1) (7 h day(-1), 3 days week(-1)) and simulated rain (SR) adjusted with H(2)SO(4) + HNO(3) to pH 5.5, 4.0, or 2.5 (2 cm in 1.5 h per event; 2 events week(-1)) over 3 weeks in a greenhouse. Ozone suppressed shoot

Effect of Simulated Acid Rain on Sulfate Movement in Acid Forest Soils

Soil Science Society of America Journal, 1980
Abstract The effect of simulated acid rain on sulfate mobility in ironpodzol and semipodzol (Typic Udipsamments) forest soils of southern Norway was studied. The study was carried out with lysimeters with undisturbed soil. The lysimeters were watered with ‘rain” having pH 5.6 and 4.3.

Simulated acid rain (H2SO4) and microbial activity in soil

Soil Biology and Biochemistry, 1983
Abstract Soil mixtures containing 9% kaolinite, 9% montmorillonite, or no clay supplements were amended with 1% glucose and treated with H2SO4 to lower their bulk pH to levels ranging from 5.4 to 0.8. Acidification had little effect on soil respiration (CO2 evolution) until the pH was lowered below 3.
