کانی شناسی سطحی خاکهای سولفاته اسیدی ساحلی، در ناحیه شهری پینجارا، جنوب غربی استرالیا
Acid sulfate soils in Western Australia commonly occur in coastal regions. One of the greatest threats to coastal environment is the disturbance of acid sulfate soils due to urban development which can lead to widespread acidification of lands and streams and subsequent economic losses onsite or in adjacent areas. Surface sampling from different landforms of the study area and analytical result...
متن کاملAcid Sulfate Wetlands in the Nsw Coast, Australia: Chemical Characteristics and Their Implications for Environmental Remediation
Abstract. Acid sulfate wetlands are widespread in the New South Wales (NSW) coast, Australia. Acid sulfate soils have caused severe environmental problems in the area with land scalding, accompanied by the discharge of highly acidic drain water into estuarine waterways being the worst-case scenario in these landscapes. The investigated acid sulfate scalds are characterized by an extremely acidi...
متن کاملLiberation of sulfate from sulfate esters by soils.
When incubated with acid, alkaline, and neutral soils, a variety of synthetic sulfate esters representing the various classes of these compounds was hydrolyzed by enzymes, probably of microbial origin. The appearance of sulfate in the soil water occurred immediately after introduction into the soils with some esters, whereas with others it occurred only after lag periods. Heat treatment destroy...
متن کاملPyrite in acid sulfate soils: transformation and inhibition of its oxidation by application of natural materials
Worldwide estimate of acid sulfate soils is 12–14 million ha. In Malaysia, they occur mainly along the coastal plains of Peninsular Malaysia and Sarawak. The soils are characterized by very low pH and high amounts of exchangeable Al, resulting from oxidation of pyrite when the soils are drained. This paper explains the transformation of pyrite when the soils undergo weathering due to drainage. ...
متن کاملInhibition of Urease Activity in Soils
Studies to evaluate more than 100 compounds as inhibitors of urease activity in soils showed that dihydric phenols and quinones were the most effective organic compounds tested and that silver and mercury salts were the most effective inorganic compounds. When the most potent inhibitors were compared using 50 1'8 of inhibitor per g of soil, their effectiveness decreased in the order: catechol >...
