“…Hourly emissions from forest fires are taken from the MACC global fire assimilation system (Kaiser et al, 2012). Emissions of NO from soils are included using the parameterization depending on soil type and soil temperature from Novak and Pierce (1993). For the emissions of isoprene and terpene the MEGAN routine is available (Guenther et al, 2006), but for Europe a slightly different approach is taken using a tree species database, as described in Beltman et al (2013).…”

Airborne Emissions from Mn Ferroalloy Production

Airborne emissions from metal production represent a health, safety, and environmental challenge to which more and more attention is being directed. Industries worldwide, as well as authorities and others, are resolute in their aim of limiting, reducing, and ultimately eliminating these emissions. Many lessons can be learned by sharing information between industrial branches, as many industries face similar challenges. Certain challenges are, however, highly branch specific. For the Mn ferroalloy industry, such examples include the types of dust generated in the primary processes and the management of polycyclic aromatic hydrocarbons (PAHs) and mercury with respect to furnace design and operation. This article covers airborne emissions from manganese ferroalloy production, including greenhouse gases, nitrogen oxides (NO x), sulfurous gases, PAH, airborne particulate matter, and trace elements, including mercury and other heavy metals. The aim is to summarize current knowledge in a state-of-the-art overview intended to introduce fresh industry engineers and academic researchers to the technological aspects relevant to reduction of airborne emissions.

“…According to their morphology and physiology, they reflect changes in environmental conditions quickly. Therefore, they are generally accepted as good indicators for environmental monitoring (for example, Zechmeister et al 2003;Tuba et al 2011;Ares et al 2012;Nickel et al 2017).…”

Thirty-eight samples recovered from a latrine in the rural market town of Hadersdorf am Kamp (Lower Austria) and filled during the early 17th century were analysed and compared to the current bryophyte vegetation there and in its surroundings. Twenty-eight moss species from the latrine could be identified, and four taxa could be determined only to genus level because of missing sporophytes. The resulting data set is a valuable contribution to the state of knowledge of the bryophyte flora of that historic period, as none of the traditional methods such as herbaria date back to this early era. The most frequent species in the pit, Leucodon sciuroides, Antitrichia curtipendula and Neckera complanata, could hardly be found or not at all in the current bryophyte flora of the investigated area. A comparison of Ellenberg's indicator values of the historic and current moss taxa revealed significant differences for temperature, humidity and continentality. Temperature values were much lower for the taxa found in the latrine. Furthermore, the historic mosses reflect a more humid and less continental climate than the ones growing nowadays. Many of the mosses found in the latrine are epiphytic or epilithic and could not be found in the investigated area today. These results indicate a different climate during the time of the Little Ice Age in the investigated area. According to the low total biomass of mosses in the pit (1-2 g per 10 l) we suggest that those found in the latrine arrived there mainly by chance, as in sweepings.
