Activity of Earthworm in Latosol Under Simulated Acid Rain Stress

Bulletin of Environmental Contamination and Toxicology, 2014
Acid 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 ...

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.

Corrosion of Permeable Concrete under Simulated Acid Rain

Key Engineering Materials, 2012
A long time immersion test of concrete specimens in dilute sulfuric acid is carried out to study the permeable concrete material aging rule under the action of the sulfuric acid. The experiment is designed by uniform design containing 4 factors and 10 levels and the soaking solution pH value is 4.00. To measure acid consumption, titration sulfuric acid

Effects of simulated acid rain on fertility of litchi.

Journal of environmental sciences (China), 2006
The regulatory role of calcium in fertility of pollen and pistil under simulated acid rain was investigated. The germination percentage of pollen treated with acid rain of pH 4.5 was 9.42% lower than that of control, and that of pH 3.5, pH 2.5 and pH 1.5 were 22.47%, 45.49% and 71.62%, respectively.

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 ...

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 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.

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
