The fireplace combustion of wood is a significant and largely unregulated source of emission pollution. Therefore article deals about experimental measurements of emission parameters from combustion of biomass in small heat sources. The objectives of the present work are to analyse basic pollutants arising from the combustion process and to define measurement technique applied to characterise particle emissions from biomass combustion. Gravimetric methods are among the most accurate and precise methods of quantitative analysis and therefore was selected for measurement of solid emissions. Conclusion of work focus on evaluation of the tests results, especially concentration of particulate matter (PM) from the combustion of briquettes made from different kinds of biomass. During the combustion of certain briquettes was recorded a high amount of particulate matter and analyser switched to “stand by” mode in several cases. The results indicate that higher concentration of PM was determined in the case of briquettes made from phytomass in comparison to briquettes made of woody biomass.

Solid particle emissions from burning wood in three internal combustion biomass cooking stoves commonly used in southern Chile were compared. Each stove was used to show differences in sealing systems, combustion chamber shape, and heating surfaces in order to optimize biomass combustion and the energy produced at a low manufacturing cost. The influence of cooking stove design along with particle and gas emissions that resulted from the biomass combustion within the cooking stove was investigated in this study. Levels of diverse atmospheric contaminants, such as particulate matter, emission factor, NOx, CO2, and CO, and the temperature of the flue gases were determined with the Ch-28 method and UNE-EN 12815. The average emission of particulate matter was significantly reduced by modifying the geometry of the combustion chamber and heating surface of each stove, resulting in 5 g/h particle emissions in conventional equipment and 2 g/h in the improved equipment. In relation to gas emissions, there was a 25% maximum decrease in NOx gases and 35% in CO after modifying the heating surface of each stove. This background supports the evidence of technological improvement with high environmental impact and low economic cost for local manufacturers.

SummaryIn this review the interaction between invasive human pathogens expressing plasmin(ogen) receptors and/or producing plasminogen activators with the human plasmin(ogen) system is described. Evidence is presented for multiple mechanisms by which human pathogens can acquire a surface bound form of plasmin that cannot be regulated by host serpins. The potential importance of these pathways in providing the organisms with the ability to cross tissue barriers is discussed.
