A Comprehensive Screen for Volatile Organic Compounds in Biological Fluids

Mathematical Modeling for Volatile Organic Compounds Removal in a Biofilter: Model Validation and Sensitivity Analysis

Nonvolatile, semivolatile, or volatile: redefining volatile for volatile organic compounds.

UNLABELLED Although widely used in air quality regulatory frameworks, the term "volatile organic compound" (VOC) is poorly defined. Numerous standardized tests are currently used in regulations to determine VOC content (and thus volatility), but in many cases the tests do not agree with each other, nor do they always accurately represent actual evaporation rates under ambient conditions. The pa...

Volatile Organic Compounds in Uremia

BACKGROUND Although "uremic fetor" has long been felt to be diagnostic of renal failure, the compounds exhaled in uremia remain largely unknown so far. The present work investigates whether breath analysis by ion mobility spectrometry can be used for the identification of volatile organic compounds retained in uremia. METHODS Breath analysis was performed in 28 adults with an eGFR ≥ 60 ml/min...

Recent Advances in Microextraction Methods for Sampling and Analysis of Volatile Organic Compounds in Air: A Review

Human exposures to volatile organic compounds (VOCs) are associated with a wide range of health problems. Due to these adverse effects of VOCs on the human health, determination of trace levels of VOCs is very important for accurate assessment of indoor and outdoor exposure. Solid phase microextraction (SPME), needle trap device (NTD) and hollow fiber- liquid phase microextraction (HF-LPME) are...

Measurement of Volatile Organic Compounds

To answer critical questions regarding the interactions between green plants and air quality, two three-year projects are underway to investigate emission of volatile organic compounds (VOC) from selected plant species. These biogenic VOC (BVOC) and oxides of nitrogen (NOx) can react in the lower atmosphere in the presence of sunlight to form ozone and secondary particulate matter, the principa...
