Abstract :

Most biomasses include a multitude of different microorganisms such as bacteria, fungi, viruses, and parasites. During the
biodegradation of organic matter, many microorganisms are capable of converting a wide range of carbon, nitrogen and
sulfur sources of biomass into chemical compounds such as gases via fermentation and anaerobic decomposition. These biological
and chemical agents may spread to the air during biomass processing in open sites. Our occupational measurements at different
biomass processing plants have revealed very high levels of worker exposure to dangerous substances; levels which are over the
health-based recommended limits. Multiple biological and chemical exposure may increase worker health effects such as acute
toxic effects, respiratory symptoms and diseases, infections, and allergies. In order to prevent health hazards among workers, all
valuable preventive working techniques and tools should be taken into use to keep occupational exposure as low as possible. These
factors should be taken into account before work is begun. Workers may be exposed to hazardous substances through inhalation,
direct contact with skin or eyes, or via the mouth. Some microorganisms can survive on surfaces for extended periods of time.
Therefore, regular cleaning is also important to inhibit the spreading of microorganisms. Surfaces must be designed to be easily
cleaned and workers must have opportunities to wash and take care of personal hygiene. Workers’ exposure should primarily be
diminished through technical solutions: protective clothing and respiratory equipment should be secondary alternatives.

Biography :

Sirpa Laitinen, has 20 years of experience in investigating exposure to biological and chemical agents that cause adverse health effects in different occupational and indoor
air environments. Exposure evaluations have been tailored to the company’s needs, and have given her a clear picture of the companies’ work environments, workplaces
and problems. She has been a senior researcher in many large studies and has published over 40 international peer-reviewed publications. The last biomass studies are
supported by the Finnish Work Environment Fund and the Finnish Funding Agency for Innovation in the Sustainable Bioenergy Solutions for Tomorrow research program.
