Health Effects and Exposure Assessment to Bioaerosols in Indoor and Outdoor Environments


Book Description

Air pollution, due to natural and anthropogenic sources, incurs enormous environmental costs. The issue of healthy living spaces and good air quality is a global concern, because each individual inhales 15,000 L of air every 24 h. Thus, contemporary monitoring and reducing exposure to air pollutants presents a particular challenge. One of the crucial indicators of indoor and outdoor air quality is bioaerosols. They play an instrumental role as risk factors when it comes to adverse health outcome. These indicators, also known as primary biological airborne particles (PBAPs), have been linked to various health effects such as infectious diseases, toxic effects, allergies, and even cancer. PBAPs include all particles with a biological source in suspension in the air (bacteria, fungi, viruses, and pollen), as well as biomolecules (toxins, and debris from membranes). To foster our current scientific knowledge on bioaerosols, research related to the characteristics of biological aerosols in indoor and outdoor environments, the methods used to improve air quality, as well as the health effects of and exposure assessments to bioaerosols, have been collected in this book.

Atmospheric Microbial Aerosols


Book Description

A bioaerosol is a colloidal suspension of liquid droplets or solid particles in air whose components contain or have attached to them one or more microorganisms. Bioaerosols are an exciting and vital object of study because the attached microbes play a critical role in human, animal and environmental health. In an era of genetically engineered microorganisms and the application of biopesticides, bioaerosols are increasingly an environmental problem, both indoors and outdoors, and can affect entire ecosystems. Atmospheric Microbial Aerosols examines naturally occuring bioaerosols, as well as bioaerosols generated by human activity. Included in this volume is a complete array of topics concerned with outdoor microbial bioaerosols ranging from the physical and chemical to the meteorological and microbial. It will be of great interest as a starting point for researchers interested in outdoor microbial bioaerosols as well as for those interested in atmospheric dispersion models, new equipment, and government regulations.

The text also offers critiques concerning handling the samples to provide representative and meaningful assays for their viability, infectivity, and allergenicity. A wide range of microbes-viz., viruses, bacteria, fungi and pollens, and their fragments-are considered from such perspectives. Bioaerosols Handbook is divided into four parts, providing a wide-ranging reference work, as well as a practical guide on how best to sample and assay bioaerosols using current technology.




Aerosol Science


Book Description

AEROSOL SCIENCE TECHNOLOGY AND APPLICATIONS Aerosols influence many areas of our daily life. They are at the core of environmental problems such as global warming, photochemical smog and poor air quality. They can also have diverse effects on human health, where exposure occurs in both outdoor and indoor environments. However, aerosols can have beneficial effects too; the delivery of drugs to the lungs, the delivery of fuels for combustion and the production of nanomaterials all rely on aerosols. Advances in particle measurement technologies have made it possible to take advantage of rapid changes in both particle size and concentration. Likewise, aerosols can now be produced in a controlled fashion. Reviewing many technological applications together with the current scientific status of aerosol modelling and measurements, this book includes: Satellite aerosol remote sensing The effects of aerosols on climate change Air pollution and health Pharmaceutical aerosols and pulmonary drug delivery Bioaerosols and hospital infections Particle emissions from vehicles The safety of emerging nanomaterials Radioactive aerosols: tracers of atmospheric processes With the importance of this topic brought to the public's attention after the eruption of the Icelandic volcano Eyjafjallajökull, this book provides a timely, concise and accessible overview of the many facets of aerosol science.
