  • 5 Habits that are bad for your indoor air quality

    School is starting, but warm weather means we are still spending more time outside and keeping windows open as much as possible. However, it doesn’t mean we are safe from poor indoor air quality at home. In fact, indoor air may be more polluted in the summer months than in the wintertime. The reasons include high humidity, pollutant buildup, pesticides and VOCs. There are certain habits in ...

  • Contamination levels and potential sources of organic pollution in an Asian river

    The Houjing River has long been an environmental victim of economic development. Industries that have settled along the bank of this river may have largely contributed to severe organic wastes pollution. This study collected water and sediment samples at various points along the river and measured concentrations of 61 volatile organic compounds (VOCs) and 128 semi-volatile organic compounds ...

  • Odorous volatile organic compound (VOC) emissions from ageing anaerobically stabilised biosolids

    Opportunities for the beneficial re-use of biosolids are limited by nuisance odour emissions. Volatile organic compounds (VOCs) from anaerobically stabilised biosolids were measured to identify compounds that could contribute to the overall odour character of nuisance emissions. Flux hood sampling and chemical analysis were used to identify VOCs emitted from biosolids as they were stored in ...

  • What is a Volatile Organic Compound (VOC)?

    What is a Volatile Organic Compound (VOC)? Our products are known for monitoring many different gases, but if you look closely at the description of some of them, you will see that it mentions the acronym VOC. For those that don’t know what VOC means, it stands for volatile organic compound, and there are thousands of different ones produced and used in our daily lives. ...
