“…The local sources of Pb can be attributed to the tire wear, burning of electronic and plastic waste [43,44]. The leaded petrol which was banned from usage before a decade, however, can exist along with the road dust for a long time [45], the road dust particles get re-suspended due to frequent movement of vehicles. Moreover, in an earlier study, elevated concentration of Pb was reported near a cement plant in the state of Chhattisgarh, India [46].…”

To study the physical and chemical properties of atmospheric particulate matter over Dehradun city located along the foothills of the Himalayas, both in situ and satellite-based observations were utilized in the present research. Ambient respirable suspended particles denoted by PM 10 (atmospheric particulate matter having an aerodynamic diameter of ≤ 10 µm) was measured during 2016-2017. The morphology and elemental characteristics of PM 10 was studied through scanning electron microscopy (SEM) and SEM-energy-dispersive X-ray spectroscopy, respectively. The 24-h mean ± standard deviation of PM 10 was observed to be 158.6 ± 33.4 µg/m 3 , which is more than 2 times the permissible limit of World Health Organization (50 µg/m 3). Microscopic analysis revealed particles with irregular, porous, rounded, flaky, chain and branched structures indicating various types such as tar balls, soot, crystalline and biogenic particles. The frequently found particle types were investigated for the atomic percentage contribution, which revealed vehicular exhaust, industrial emission, biomass burning, and crustal/dust re-suspension as the chief source of PM 10. To delineate the source and transport pathway of air masses converging over the city, 24-h air mass back trajectories were associated with MODerate resolution Imaging Spectroradiometer derived fire spots, geographical location of cement manufacturing and thermal power plants in the vicinity of monitoring site. Excess cancer risk due to inhalation of Lead particles (mean = 0.159 µg/m 3) associated with PM 10 was 0.16 × 10 −6 , which is well below the safe limit (1 × 10 −6) framed by the United States Environment Protection Agency.

“…Isotopic data on aerosol TEs may also be useful in distinguishing sources, such as between biomass burning or mineral dust for Fe [ 11 ], between anthropogenic emissions or mineral dust for Zn [ 98 ] or between combustion aerosols from different regions with Pb isotopes (e.g. [ 99 ]).…”

The importance of the atmospheric deposition of biologically essential trace elements, especially iron, is widely recognized, as are the difficulties of accurately quantifying the rates of trace element wet and dry deposition and their fractional solubility. This paper summarizes some of the recent progress in this field, particularly that driven by the GEOTRACES, and other, international research programmes. The utility and limitations of models used to estimate atmospheric deposition flux, for example, from the surface ocean distribution of tracers such as dissolved aluminium, are discussed and a relatively new technique for quantifying atmospheric deposition using the short-lived radionuclide beryllium-7 is highlighted. It is proposed that this field will advance more rapidly by using a multi-tracer approach, and that aerosol deposition models should be ground-truthed against observed aerosol concentration data. It is also important to improve our understanding of the mechanisms and rates that control the fractional solubility of these tracers. Aerosol provenance and chemistry (humidity, acidity and organic ligand characteristics) play important roles in governing tracer solubility. Many of these factors are likely to be influenced by changes in atmospheric composition in the future. Intercalibration exercises for aerosol chemistry and fractional solubility are an essential component of the GEOTRACES programme.This article is part of the themed issue ‘Biological and climatic impacts of ocean trace element chemistry’.

Abstract. The western Himalaya glaciers seasonally melt, in part, controlled by the presence of ice surface impurities in the form of dust, organic, and inorganic particles. The hitherto knowledge that dark-colored impurities on the ice surface are a mechanistic driver of heat absorption and thus enhancing ice mass wasting makes understanding the concentrations, origin, and pathways of emission residues on the glacier surface a global concern to conserve the Himalayan ice mass that provides water to more than one billion people. Yet, the source, origin, and pathways of metal impurities on the ice surface of Himalayan glaciers remain poorly constrained. Here, we present major and trace element geochemistry, rhenium-osmium (Re-Os) isotopes composition of cryoconite – a dark-colored aggregate of mineral and organic materials – on the ablation zone of the Chhota Shigri Glacier (CSG) considered as a benchmark glacier for process understanding in the western Himalaya. We find that the cryoconite possesses elemental ratios and crustal enrichment factor that reveal a predominant crustal source. Further, the 187Os/188Os composition in cryoconite varies from non-radiogenic (0.36) to radiogenic (1.31) compositions. Using a three-component isotope mixing model we show that the Os in cryoconite is dominantly derived from local rocks with negligible input from anthropogenic Os sources. Given that the CSG has limited debris cover (~ 3.4 %) and the near absence of anthropogenically derived particles; our results suggests that dark-colored surficial deposits of anthropogenic dust particles are not one of the significant drivers of glacier melting in the western Himalaya, as observed elsewhere.
