  • Fungal Biodegradation

    Introduction The utilization of fungal biodegradation involves the controlled usage of these specially cultivated fungi to treat contaminants. White Rot Fungus White rot fungus has been reported to degrade a wide variety of organopollutants because of its lignin-degrading or wood-rotting enzymes. Two different treatment configurations have been tested for white rot fungus, in situ and ...

  • Anti-fungal compounds: emerging environmental contaminants

    Azole fungicides are active ingredients in a range of pharmaceutical and personal care products, and are also used in agriculture. This study reviewed the sources, presence and risks of these compounds in the environment, finding evidence of toxic effects on aquatic organisms. The researchers provide directions for future research and warn caution should be exercised until more toxicity data ...

  • Process-generated contaminants

    Overview: There is not currently a formal and universally recognised definition of a process-generated substance. Process-generated contaminants can be generated as emissions from combustion processes, abrasion and/or other processes that physically or chemically degrade or otherwise modify the starting material(s), e.g. degradation/composting of organic materials. Such ...

  • Effect of gaseous chlorine dioxide on indoor microbial contaminants

    Traditional and modern techniques for bioaerosol enumeration were used to evaluate the relative efficiency of gaseous chlorine dioxide (ClO2) in reducing the indoor microbial contamination under field and laboratory conditions. The field study was performed in a highly microbially contaminated house, which had had an undetected roof leak for an extended period of time and exhibited large areas of ...

  • Just How Often are Drugs that are Supposed to be Sterile, Actually Contaminated?

    A few weeks ago, NBC News published the report, “Sterile drugs often contaminated, pharmacists admit.”  The article was written shortly after the peak of the fungal meningitis outbreak caused by contaminated injections that resulted in dozens of deaths and hundreds of infections. The article references a poll conducted by the Institute for Safe Medication ...

  • Effective DNA extraction method for molecular diagnostics on wood-decay fungi

    1. INTRODUCTION Strategically eliminating damage caused by fungus requires precise identification of the fungal species present (using either conventional or molecular diagnostic techniques). The first step in performing molecular diagnostics on wood-decay fungi is to obtain analyzable fungal DNA. Five commercially available kits and one CTAB method were tested and analyzed ...

  • United States Virgin Islands

    Our firm was privileged to perform an indoor air quality related abatement that also had a historical context. This involved an adverse exposure to the Governor of the USVI at the Governor's residence in Catharineberg, St. Thomas. We determined that Stachybotrys and other toxigenic fungi were present in the residence as a result of water leaks from the roof and indirect effects from air ...

  • The toxic legacy of Thailand’s ‘Great Flood’ will remain long after the waters have receded

    This year’s unusually long rainy season has left many part of Thailand, Lao and Cambodia inundated and resulted in the worst flooding crisis in Thailand for at least 50 years. The provinces of the central plains and many districts in the north, east and west of metropolitan Bangkok are now effectively under water. The huge volume of floodwater is such that flood levels are 3 metres deep in ...

  • Sick-building syndrome and building-related illness

    Significant health problems linked to very poor indoor air qualityIndoor Air Quality (IAQ) deals with the content of interior air that could affect health and comfort of building occupants. The IAQ may be compromised by microbial contaminants (mold, bacteria), chemicals (such as carbon monoxide, radon), allergens, or any mass or energy stressor are more prevalent than anyone could have predicted. ...

  • UV Light Treatment for HVAC Systems

    Ultraviolet (UV) light can be applied to support numerous applications in a broad range of industries. In commercial paint spray booths and label manufacturing plants, UV lamps are used to streamline paint jobs and the printing of logos. Outside of such practices, the light source may also be utilized to eradicate harmful, disease-causing bacteria. Systems that rely on the light’s ability ...

  • Putting infection control into practice in the workplace

    Healthcare workers are, like patients, subject to illness from a variety of airborne pathogens common to hospital settings. This risk increases during construction and renovation, as these endeavors release dust as well as disease-inducing microbes into the surrounding environment. Since more than one in five workplace illnesses in private industry occur in a hospital setting , hospitals ...

  • Awareness of Fungi on Wood is Critical to Professionals

    Untitled Document Those who deal with indoor fungal contamination could benefit by understanding more about the biology of common types of fungi on wood and wood products. It may assist in identifying potential ...

  • Minimising Risks to Air Quality and Regulatory Compliance With Total Filter Management

    It has been shown in recent studies that as much as 25% of the total site operating budget (excluding raw material costs) for a typical medium-large dosage-form manufacturing facility will be spent on compliance measures for internal quality systems and external regulatory activities. (1) Market realities indicate that the pharmaceutical companies will need to address the overall cost of ...

  • Nature’s Own - Biofiltration process offers promise of (near) energy-free pollution abatement

    A filter could be described as any substance through which liquid is passed to remove suspended impurities. Although a “biofilter” is actually not a filter, “biofiltration” is on the threshold of finding a market as a compliance solution for air pollution regulations after a number of false starts. Biofilters have long been used as a means for reducing objectionable odors in Germany, the ...
