  • Interhemispheric transport of viable fungi and bacteria from Africa to the Caribbean with soil dust

    Daily aerosol samples collected in trade winds at Barbados, West Indies, throughout 1996–1997 yielded significant concentrations of viable (culture-forming) bacteria and fungi only when African dust was present. Air masses from the North Atlantic, North America, and Europe yielded no cultivable organisms. The strong association of cultivable organisms with African dust suggests various factors ...

  • Isolation and identification of airborne fungi that can cause asthma: a case study from Eastern Puerto Rico

    Asthma is a growing worldwide chronic disease increasing in both prevalence and exacerbations throughout the late 20th century. The US. Centre for Disease Control reports showed that Puerto Rico had a higher overall prevalence of lifetime (19.6%) and current (11.6%) asthma. The central eastern region of the island has the highest prevalence in the age range of 0-17. The goal of this study was to ...

  • Presence and survival of fungi and clostridium Tyrobutyricum during anaerobic treatment of organic household waste

    Today the anaerobic microbial process of biogas formation is more into focus than ever. This interest is due to the fact that is offers the community means of fulfilling several obligations: treatment of organic wastes, recirculation of nutrients between urban and rural areas and production of renewable energy. Presently, several Swedish cities have built centralised biogas plants, treating ...

  • Indoor Air Quality Myths Debunked

    Today’s buildings, whether it is a home, office, manufacturing plant, hospital, etc., are more energy efficient; however, they also foster a potentially harmful environment. Indoor Air Quality (IAQ) has become a rising concern in the HVAC industry. Poor IAQ can cause a number of health issues such as, allergies, dryness and irritation to the eyes, nose, throat, and skin. It can also cause ...

  • Study of the indoor air quality in hospitals in South Chennai, India — microbial profile

    A 3-month pilot study (February—April 2006) was conducted to determine the quality of indoor air in hospitals in the Tamil Nadu region of India and to characterize the predominant aerobic bacteria and fungi present. The main objectives were (1) to sample the indoor air of three different hospitals in Chennai for bioaerosols to generate baseline data using the Petri plate gravitational settling ...

  • Assessment of ambient air quality in Bishnumati corridor, Kathmandu metropolis

    The Kathmandu valley urban area is growing as a metropolis. Bishnumati corridor in Kathmandu valley is is a target of increased pollution. The unabated solid waste land-filling on either side of the river-bank and animal slaughter houses and biological waste arising from these activities, busy commercial and high residential density characterize the corridor. Six areas, namely Teku Dovan, ...

  • Response of arbuscular mycorrhizal mungbean plants to ambient air pollution

    Abstract:The experiments were conducted in open top chamber system installed at the University of the Punjab, Quaid-e-Azam Campus, Lahore, Pakistan. The mungbean (Vigna radiata (L.) Wilczek var.M28) seeds were sown in earthen pots and were kept in filtered air, unfiltered air and ambient air. The ozone concentration was monitored daily during 1000hrs till 1600 h. The data for light intensity ...

  • The MoldRange Report

    What is MoldRANGE?MoldRANGE is a compilation of data from thousands of outside air samples analyzed by EMLab P&K. It enables a person to get a sense of the fungi that are typically present in the outside air both by time of year and region of the country. All data has been compiled from analysts who have college degrees in biology or a related field, have gone through intensive training, have ...

  • Suffer from Allergies or Asthma?

    The “ULTRA” washable air filters have an antimicrobial protection that will not allow bacteria, fungi or mold to grow on the filter surface. The antimicrobial protection is not a coating and is not sprayed on. It is a safe and effective antimicrobial agent processed directly into the electrostatic fiber media, rendering it as permanent as the filter itself. The University of ...

  • Occupational hygiene at a drum composting plant in Hyvinkää, Finland

    Refuse disposal and treatment must be safe for employees. Organic dust of waste origin, perhaps containing microbes, may be harmful to health. Microbes, especially fungi but also thermophilic Actinomycetes bacteria, may cause allergy and asthma (Terho et al. 1993; Madigan et al. 1997). Usually fungi cause hypersensitivity (Madigan et al. 1997) and the most common syndrome is allergic rhinitis ...

  • 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 ...

  • Exposure to dust, endotoxin and airborne microorganisms in wastewater sludge thermal drying units

    The objective of this study was to assess workers' exposure to bioaerosols in sludge drying units. Simultaneous collection of inhalable dust and airborne biological agents was carried out using rotating cup samplers (CIP 10, Arelco). Sixteen stationary and 30 personal measurements were performed in three drying plants, during summer and winter. Microbial content of air was characterized by high ...

  • 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 ...


  • The MoldScore Report

    When evaluating indoor levels of most pollutants, one can collect air samples, compare the sampling results to established exposure standards, and make relatively unambiguous decisions regarding the need for remediation. Bioaerosols as a group are not amenable to this general methodology, due to the difficulties in the development of such exposure standards for reasons that have been discussed ...
