Greenland Ice Cores Show Industrial Record Of Acid Rain, Success Of U.S. Clean Air Act
The rise and fall of acid precipitation may be a world experiment whose results are preserved within the geological record.
By analyzing samples from the Greenland ice sheet, University of Washington atmospherical scientists found clear proof of the U.S. Clean Air Act. They additionally discovered a link between air acidity and the way gas is preserved in layers of snow, per a paper published on within the Proceedings of the National Academy of Sciences. 
Development of Fiber Optic Chemical Sensor for Monitoring Acid Rain Level
Acid rain event is incredibly dangerous for human action particularly in 5 cities of the Dutch East Indies. Here, air pollution has systematically attacked over 5 cities in Dutch East Indies cherish national capital, Manado, Pontianak, Bogor, and Surabaya with average pH scale level four.22 to 6.34 in July 2010. Thus, during this study aim to develop Fiber Optic Chemical detector (FOCS) for observance air pollution level over 5 cities in Dutch East Indies. the event of FOCS is employed impermanent wave sort and photodiode FDS10X10 to observe air pollution quality. during this study, the Optical meter (OPM) is employed as a validator instrumentation to capture FOCS capability. 
Exogenous Melatonin Improves Fruit Quality Features, Health Promoting Antioxidant Compounds and Yield Traits in Tomato Fruits under Acid Rain Stress.
Acid rain could be a serious worldwide environmental drawback that reduces the expansion and yield of crops. Melatonin, as a pleiotropic molecule has been glorious to enhance stress tolerance by limiting the aerophilous harm of plants exposed to adverse environments. However, the role of exogenous internal secretion significantly on the yield and inhibitor compounds in tomato fruits beneath abiotic stress condition remains ineffable. This observation aims to spot the influence of internal secretion treatment beneath simulated air pollution (SAR) condition on fruit qualities, phenolics, flavonoids, and carotenoids concentration in fruits, and yield of tomatoes. Our study results showed that the fruits of SAR-stressed plants had higher quality traits and inhibitor bioactive compounds by increasing inhibitor activities against SAR-induced aerophilous stress compared with fruits of management plants. 
Swift Acid Rain-Sensing by Synergistic Rhizospheric Bioelectrochemical Responses
Acid rain poses important threats to crops and causes a decline in food production, however current watching and response to acid precipitation injury is either slow or costly. The direct injury observation on plants will take many hours to days once the injury is irreversible. This study presents a true time bioelectrochemical watching approach that may notice acid precipitation injury among minutes. The rhizospheric bioelectrochemical device (RBS) takes advantage of the quick chain responses from leaves to roots, so to the microbic chemistry reactions within the rhizosphere. Immediate and repeatable current fluctuations were discovered among a pair of min when acid precipitation and such changes were found to correspond well to the changes in rhizospheric organic concentration and chemistry responses. Such correlation not solely may be discovered throughout acid precipitation events that may be remedied via emotion, however, it absolutely was conjointly valid once such injury is irreversible, resulted in zero current, photosynthetic potency, and chemistry signals. The amino acid, aspartate, and salt metabolism and saccharose metabolism in leaves and roots were restrained by the acid precipitation, that resulted within the decrease of rhizodeposits akin to acid, d-galactose, and d-glucose. 
Effect of Simulated Nitric and Sulphuric Acid Rains on the Nutrient Content of Amaranthus hybridus L.
Aims: to judge the potential effects of a simulated chemical element and sulfuric acid rain on the proximate, minerals, vitamins and antinutrients contents of genus Amaranthus hybridus plant scientist (A. hybridus).
Study Design: The study was administrated during a complete randomized block style.
Place and Duration: Department of biological science, University of Calabar, Calabar, African nation between March and Gregorian calendar month, 2016.
Methodology: Plants were harvested at 2 months post simulated chemical element and sulfuric acid rain treatments. The leaf, stem, and root were separated, dried, processed into powder and used for proximate, minerals, vitamins and antinutrients analysis per customary ways. Simulated air pollution pH a pair of.0, pH 3.0, pH 4.0 and management pH six.0 were used.
