The source profile of volatile organic compounds (VOCs) is essential for establishing reactivity- and toxicity-based emission inventories developing effective air pollution control strategies. In this paper, the establishment VOC profiles characteristics are reviewed in petrochemical, solvent use, chemical industries, most up-to-date three industries China compiled via necessary adjustment reco...
With the revision of Air Pollution Control Act in Taiwan announced on 1 August 2018, several provisions or regulations have been added to strengthen control hazardous air pollutants (HAPs) from stationary sources. Therefore, this paper conducted a survey sixty toxic volatile organic compounds (VOCs) designated as HAPs and also performed comparison between some developed countries (i.e., USA, Ja...
Automotive manufacturing is one of the potential sources air pollution particularly involving volatile organic compounds (VOCs). This study intensively evaluated VOC emissions and their dispersion from industry. The measured VOCs were speciated for further evaluation odor threats according to characteristics each compound. Mathematical emission models applied assist in elaborating source–recept...
In Guadeloupe (French West Indies), the main municipal solid waste is surrounded by highly urbanized areas. An urban heat island (UHI) behavior has been identified in the landfill environment. It has been measured and its intensity (up to more than 4 C) has been shown to be negatively correlated with nebulosity and Tradewinds strength. Conditions for urban breeze detection have been examined. T...
It has long been recognised that pollutant gases cause significant impacts on crops and studies conducted revealed that ground-level ozone is responsible for most of the crop-yield losses from air pollutants whereby losses from other pollutants are minimal, relative to ozone (Fuhrer et al., 1997; Pleijel et al., 1998; Ishii et al, 2004). Ozone is a secondary pollutant resulting from photochemic...
Virtual Organization Clusters (VOCs) provide a novel architecture for overlaying dedicated cluster systems on existing grid infrastructures. VOCs provide customized, homogeneous execution environments on a per-Virtual Organization basis, without the cost of physical cluster construction or the overhead of per-job containers. Administrative access and overlay network capabilities are granted to ...
In plant-associated Pseudomonas species, the production of several secondary metabolites and exoenzymes is regulated by the GacS/GacA two-component regulatory system (the Gac-system). Here, we investigated if a mutation in the GacS sensor kinase affects the production of volatile organic compounds (VOCs) in P. fluorescens SBW25 (Pf.SBW25) and how this impacts on VOCs-mediated growth promotion a...
Background: Diagnoses of respiratory tract infections usually happen in the late phase of the disease and usually result in reduction of the pathogen load after broad-spectrum antibiotic therapy, but not in eradication of the pathogen. The development of a non-invasive, fast, and accurate method to detect pathogens has always been of interest to resea...
Beneficial soil microorganisms can affect plant growth and resistance by the production of volatile organic compounds (VOCs). Yet, little is known on how VOCs from soil-borne plant pathogens affect plant growth and resistance. Here we show that VOCs released from mycelium and sclerotia of the fungal root pathogen Rhizoctonia solani enhance growth and accelerate development of Arabidopsis thalia...
Monitoring exhaled breath is a very attractive, noninvasive screening technique for early diagnosis of diseases, especially lung cancer. However, the technique provides insufficient accuracy because the exhaled air has many crucial volatile organic compounds (VOCs) at very low concentrations (ppb level). We analyzed the breath exhaled by lung cancer patients and healthy subjects (controls) usin...
