BACKGROUND The relationship between occupational exposures to volatile organic compounds (VOCs) and cardiovascular effects among hairdressing assistants has not been well characterized. AIMS To investigate whether or not exposure to VOCs was associated with autonomic dysfunction, inflammation and oxidative stress in hairdressing assistants. METHODS We recruited 62 young healthy assistants w...

BACKGROUND Comprehensive two-dimensional gas chromatography coupled with time-of-flight mass spectrometry (GCxGC-TOF MS) has been proposed as a powerful new tool for multidimensional analysis of complex chemical mixtures. We investigated GCxGC-TOF MS as a new method for identifying volatile organic compounds (VOCs) in normal human breath. METHODS Samples of alveolar breath VOCs and ambient ro...

Banana (Musa sp.) ranks fourth in term of worldwide fruit production, and has economical and nutritional key values. The Cavendish cultivars correspond to more than 90% of the production of dessert banana while cooking cultivars are widely consumed locally around the banana belt production area. Many plants, if not all, produce Volatile Organic Compounds (VOCs) as a means of communication with ...

The biological treatment processes found wide applications in wastewater, air & solid waste pollution control. The need for alternate cost effective treatment technologies led to similar biological treatment processes for waste gas streams. One such treatment technology is biofiltration. Biofiltration technology utilizes the microorganisms to biologically degrade Volatile Organic Compounds (VOC...

Ventilation aims at providing a sufficient air renewal for ensuring a good indoor air quality (IAQ), yet building energy policies are leading to adapting various ventilation strategies minimising energy losses through air renewal. A recent IAQ evaluation campaign in French dwellings shows important pollution of living spaces by VOCs such as formaldehyde, acetaldehyde or hexanal, particularly in...

The composition of volatile organic compounds (VOCs) in large-scale livestock farms is complex, which seriously affects the health and difficult to evaluate. In order quickly analyze pollution degree VOCs farms, electronic nose technology was used this study detect gases pig chicken houses, respectively. Firstly, gas chromatography–mass spectrometry (GC–MS) were houses at different time locatio...

Studies on the health effects of long-term average exposure to outdoor air pollution have played an important role in recent health impact assessments. Exposure assessment for epidemiological studies of long-term exposure to ambient air pollution remains a difficult challenge because of substantial small-scale spatial variation. Current approaches for assessing intra-urban air pollution contras...

Over the past seven years, the U.S. Environmental Protection Agency has consistently ranked indoor air pollution among the top five risks to public health. One of the most dangerous indoor air pollutants is carbon monoxide (CO). CO can be lethal, but perhaps more important, many people suffer ill health from chronic, often undetected exposure to low levels of this gas, resulting in fatigue, hea...

Biofiltration is one of the air pollution control technologies that utilizes the microorganisms to biologically degrade Volatile Organic Compounds (VOCs) and odor contained in waste air streams. The microorganism exists on the surface and in a thin water film surrounding the surface of biofilter material and degrades the pollutants present in the fluid. This method is distinguished from other b...

This document was developed in cooperation with the Minnesota Department of Health and staff at the Minnesota Pollution Control Agency (MPCA) Closed Landfill Programs to provide guidelines for the monitoring of methane associated with landfill gas (LFG) generated from abandoned unpermitted dumps that may pose risk to existing or proposed occupied structures. Non-methane organic compounds such a...
