Open Document Abstract: The purpose of this lab is to figure out the percentage of sodium chloride in each barrel of solution such that disposal cannot surpass five percent per liter, but also identify the volatile organic compounds found in these barrels. The first experiment will test that the...
Volatile organic compoundsHybrid processes have received more attention in pollutant removal due to the combination of advantages of each process. A membrane combined with absorption was developed and studied for the removal of volatile organic compounds (VOCs) from lab to industrial scale. The ionic ...
1. PROTOCOL FOR VOLATILE ORGANIC COMPOUNDS AND PERCHLORATE (VOC/PERCHLORATE) STUDY 1.1 Overview The purpose of the VOC/Perchlorate study is to determine the prevalence of exposures to chemicals called Volatile Organic Compounds (VOCs) and Perchlorates. Volatile organic compounds are ...
Plants synthesize and release a diverse array of volatile organic compounds (VOCs) both constitutively and in response to biotic and abiotic stresses. These volatiles can function as chemical cues or signaling molecules mediating intra- and interspecific plant interactions [1,2,3,4]. For example, s...

It has also been reported that benzaldehyde, 2-butanone and acetophenone are three of the compounds identified as potential breath markers for lung cancer, in a test which has 80% sensitivity and 100% specificity for the diagnosis of lung cancer [36]. Based on the results obtained from this...

To understand the effects of volatile compounds on the evaluation of soy sauces so their quality could be classified, samples collected over 3 consecutive years from 2015 to 2017 were evaluated then ranked. The volatile compounds of these evaluated samples were directly extracted by headspace analysis...
34. Compounds were filtered by requiring either a two-tail Student’s T-test or Wilcoxon’s Rank sum test p-value < 0.1. While not all of these compounds have an alpha <0.05, they may still have utility at constructing a multiparametric test. In addition, p-values obtained from ...
