The prognosis for potential resources of abiotic natural gas and petroleum depends critically upon the nature and circumstances of Earth formation. Until recently, that prognosis has been considered solely within the framework of the so-called "standard model of solar system formation", which is incorrect and leads ...

There are a variety of mechanisms that destroy chlorinated solvents in ground water, including reductive dechlorination (biotic or abiotic), dehydrochloroelimination (abiotic), and hydrolysis (biotic or abiotic). Most proposals for Monitored Natural Attenuation (MNA) of chlorina...

to better understand the abiotic factors underlying a natural plant productivity gradient. We related soil suggest that although richness is influenced directly by the filtering effects of the abiotic environment. However, such predictions are complicated by the fact that diversity, productivity, and the abiotic

acid, Georgetown NOM, hematite, and CN32. Abiotic experiments were conducted to quantify nitrobenzene,andhumicsubstancestobetter quantify biotic and abiotic contaminant transformations. Experimental Section Microorganism and Culture reactors were prepared with every experiment: abiotic controls that were not inoculated with CN32

Both abiotic and biotic transformations of pesticides occur simultaneously in the environment. lthough the dominance of abiotic transformations was demonstrated in some cases, it often was assumed that biotic transformations control the degradation of pesticides in natural system...

Over the past decade, there has been a growing awareness of the contribution of abiotic processes to the natural degradation of chlorinated organic contaminants in aquifer material. These abiotic processes contribute to risk management of the contaminants through monitored natur...
