    Sulfuric acid (H2S04) is a corrosive substance, destructive to the skin, eyes, teeth, and lungs. Severe exposure can result in death. Workers may be harmed from exposure to sulfuric acid. The level of exposure depends on dose, duration, and type of work being done. Field experiments were conducted for 3 yrs. to determine the effects of simulated acid rain on seed yield of two soybean (Glycine max (L.) Merr.) cultivars, 'Amsoy 71' and 'Williams 82'. Plants were treated biweekly with simulated rain of pH , , , , , and

    Sulphur dioxide and nitrogen dioxide undergo oxidation and then they react with water resulting in the formation of sulphuric acid and nitric acid respectively. The following reaction will clarify the acid formation reaction: 2SO 2 (g) + O 2 (g) + 2H 2 O (l) → 2H 2 SO 4 (aq) 4NO 2 (g) + O 2 (g) + 2H 2 O (l) → 4HNO 3 (aq). Effects of Acid Rain. Acid rain is very harmful to agriculture. Simulated sulfuric acid rain (pH , , or ) or control rain (pH ) was applied to decomposing leaf packs of 10 hardwood species. Changes in weight and chemical element concentrations were followed for days. Leaf-pack weight decreased most rapidly under the intermediate acid treatments, especially at pH

    For each crop, treatments consisted of eight acidity levels in simulated rain — pH , , , , , , , and Crops varied in response to increased rain acidity. Overall, exposure of cultivars to a range of acidities in simulated rain had very little effect on the dry biomass accumulation of shoot and root components.   The relative composition of acid rain is changing gradually from sulfuric acid rain (SAR) to nitric acid rain (NAR) with the rapidly growing amount of nitrogen deposition. In this study, we investigated the impact of simulated SAR and NAR on litter decomposition and the soil microbial community over four seasons since March

EFFECTS OF SIMULATED SULFURIC ACID RAIN ON CROP PLANTS C.J. Cohen, L.C. Grothaus, and S.C. Perrigan INTRODUCTION Acid precipitation has been identified as a major environmental concern.

The simulated acid rain has also caused reduction in plant growth and yield of field corn, green pepper, tomato etc [11,12, 13, 7,4]. The adverse effects of acid rain include chlorosis, necrosis.

Aims: Our objective was to investigate the effect of sulfur acid rain (SAR), nitric acid rain (NAR) and their mixture (MAR) on the physiology, growth and yield of the crop rape (Brassica napus). Methods: Fifteen 4 m × 5 m plots were distributed stochastically for exploring SAR, NAR and MAR stress, with a roughly m spacing between plots to avoid : Mai BoRu, Zheng YouFei, Wu RongJun, Liang Jun, Liu Xia.

Most results with simulated acid-rain exposure experiments have suggested that rain acidity below pH could induce direct or indirect deleterious effects on crops and other herbaceous plants.

Effect of simulated acid rain on root fresh weight at peak growth and maturity stages in sunflower (H. annuus L.) (CD value at Peak growth and at maturity stage ). Soybean seedlings (Glycine max) grown in a glasshouse were exposed to simulated acid rain using a solution of deionized water containing sulfate, nitrate and chloride in concentrations and proportions equivalent to those in ambient rain water.

Plants were subjected to acid rain treatment twice a week during the growing season, for a 1 hr period at a rate of 5 mm hr−1. We synthesized data from published literature on experiments of simulated acid rain, by directly exposing plants to acid solutions with varying pH levels, to assess the direct effect of acid rain.

Potted plants were grown in field chambers and exposed to simulated sulfuric acid rain (pHor ) or to a control rain (pH ). At harvest, the weights of the marketable portion, total aboveground portion and roots were determined for 28 crops.

Combining the acidification effects of sulfate ion and nitrate ion, the benefits of SO 2 reduction would almost be negated by increased N emissions.

Injury to foliage and effects on yield were common responses to acid rain. However, foliar injury was not a good indicator of effects. The major objectives of this research effort were: (1) to determine the levels of acidity in rain that alter crop productivity, (2) to evaluate varietal differences in crop response, and (3) to determine the response of crop plants to the combined stress of acid rain and gaseous pollutants [primarily ozone (O 3)].
