“…2b). The presence of pyrrhotite in coke dust was already confi rmed by Magiera et al [1] also by means of Mössbauer spectrometry. Flanders [26] provided the data that pyrite heated to about 1070°C in the absence of air dissociates to form pyrrhotite (FeS) and sulphur gas.…”

“…In both possible cases, G05 component describes the mineral of strongly defected structure, because of the very broad distribution of IS values (the variance value bigger than 0.4 mm/s). G06 component with considerably lower values of IS and QS comes presumably from paramagnetic Fe 3+ ions in amorphous (glassy) aluminosilicates (mullite-porcellanite, Al 6 Si 2 O 13 ), the presence of which in both fl y ashes and industrial dusts is widely reported in the literature [1,12,30]. The highest contribution of G05 component is stated for the sample COK1-P2 (coke dust collected in electrostatic precipitator), whereas G06 one dominates in the samples COK2-P3 and COK3-P7 (coke dusts collected by manual sweeping).…”

“…A special emphasis is placed not only on the extent and amount of pollutants but also on their geochemical, mineralogical, and phase composition. In spite of the emission rate reduction, industrial dusts produced by different kinds of industry still have hazardous impact on the environment [1,2]. Integrated magnetic, geochemical, and mineralogical methods have been applied in research that aimed at characterization of these different dusts, which contain technogenic magnetic particles (TMPs) arisen during high-temperature technological processes [3,4].…”

Iron-containing phases in metallurgical and coke dusts as well as in bog iron ore

Abstract. Several samples of dusts from steel and coke plants (collected mostly with electro fi lters) were subjected to the investigation of content of mineral phases in their particles. Additionally, sample of bog iron ore and metallurgical slurry was studied. Next, the magnetic susceptibility of all the samples was determined, and investigations of iron-containing phases were performed using transmission Mössbauer spectrometry. The values of mass-specifi c magnetic susceptibility  varied in a wide range: from 59 to above 7000 × 10 −8 m 3 kg −1 . The low values are determined for bog iron ore, metallurgical slurry, and coke dusts. The extremely high  was obtained for metallurgical dusts. The Mössbauer spectra and X-ray diffraction patterns point to the presence of the following phases containing iron: hematite and oxidized magnetite (in coke and metallurgical dusts as well as metallurgical slurry), traces of magnetite fi ne grains fraction (in metallurgical dusts), amorphous glassy silicates with paramagnetic Fe 3+ and Fe 2+ ions, traces of pyrrhotite (in coke dusts), -Fe and nonstoichiometric wüstite (in metallurgical slurry), as well as ferrihydrite nanoparticles (in bog iron ore). For individual samples of metallurgical dusts, the relative contributions of Fe 2+/3+ ions in octahedral B sites and Fe 2+ ions in tetrahedral A sites in magnetite spinel structure differs considerably.

PrefaceDear Colleagues, This year we have the pleasure to attend already the 16th "Castle Meeting" on Paleo, Rock and Environmental Magnetsim. Although 16 is not the right reason to celebrate, these meetings started exactly 30 years ago as meeting on Paleomagnetism, Rock Magnetism and Database Usage.The very first one was held in Liblice (Czechoslovakia) in 1988, being motivated by discussions held during the International Association for Geomagnetism and Aeronomy (IAGA) Assembly in 1985 in Prague. Actually, since the beginning in 1988, the meetings have been recognized by and sponsored by IAGA. I remember the first one in 1988 pretty well -I gave my very first oral presentation on paleomagnetism of rocks from Cap de Chevre (France). My shirt got completely wet and I had barely idea what I was tolking about. However, I met several great personalities in our field of research, such as legendary Vit Jelinek (who otherwise practically did not attend any meetings). One year later, in 1989, the political situation in our country changed dramatically. This change resulted in exit of several of my co-workers, including my supervisor, to private business and I was left almost alone with the decision of the first meeting to continue the organization of these events on regular bi-annual basis. Thus, I had to organize the second one in 1990 in Bechyne. At that meeting we agreed with colleagues from Bratislava (Slovakia) to hold the meetings alternately in both new countriesCzech and Slovak Republics (see the list of meetings held until now at the end of this text). As a result, it has been my privilege and great pleasure to organize, or be at hand to organizers, of these great meetings for 3 decades.These meetings got a worldwide reputation in particular for the atmosphere, which has always combined scientific work with excellent social programme, consisting of local tours, cultural performances, food and drinks tasting, etc. I especially appreciate very much that the attendees varied from regular, well recognized experts to young Ph.D. (or even master) students; many of the latter ones developed later on to well established and known scientists. All the participants easily got the idea that the meetings represent ideal training for young colleagues -acting as chairs of sessions, being evaluated for their performance and nominated for the IAGA award, etc. And one could not count how many working cooperations, projects and good personal friendships were established at these meetings. To conclude, we successfully "survived" three decades of these bright events. Four years ago we moved for the first time outside former Czechoslovakia and no doubts local organizers (Pedro Silva in Portugal in 2014 as well as Simo Spassov in Belgium in 2016) proved that they got these meetings deeply uder their skin. I only wish this trends remains also for the future, having meetings of PREFACE 2 this size, with relaxed atmosphere and participants from about 25 countries worldwide, combining various ages and cultures. It will be always my grea...

Road sediment, an underutilized material in environmental science research: A review of perspectives on United States studies with international context

Road sediment is a pervasive environmental medium that acts as both source and sink for a variety of natural and anthropogenic particles and often is enriched in heavy metals. Road sediment is generally understudied in the United States (U.S.) relative to other environmental media and compared to countries such as China and the United Kingdom (U.K.). However, the U.S. is an ideal target for these studies due to the diverse climates and wealth of geo-chemical, socioeconomic, demographic, and health data. This review outlines the existing U.S. road sediment literature while also providing key international perspectives and context. Furthermore, the most comprehensive table of U.S. road sediment studies to date is presented, which includes elemental concentrations , sample size, size fraction, collection and analytical methods, as well as digestion procedure. Overall, there were observed differences in studies by sampling time period for elemental concentrations, but not necessarily by climate in the U.S. Other key concepts addressed in this road sediment review include the processes controlling its distribution, the variety of nomenclature used, an-thropogenic enrichment of heavy metals, electron microscopy, health risk assessments , remediation, and future directions of road sediment investigations. Going forward, it is recommended that studies with a higher geographic diversity are performed that consider smaller cities and rural areas. Furthermore, environmental justice must be a focus as community science studies of road sediment can elucidate pollution issues impacting areas of high need. Finally, this review calls for consistency in sampling, data reporting, and nomenclature to effectively expand work on understudied elements, particles, and background sediments.
