“…Finally, an intermediate behavior between industrial and rural is found for the urban site, where the influence of some industrial point sources has been previously reported by Arruti et al [11]. Therefore, in terms of water soluble fraction fluxes the difference between the three sites is not so evident.…”

Cantabria is a small region located in Northern Spain that combines different land uses; thus, urban, industrial and rural areas are present in a relatively small area (5300 km 2 ); however, the anthropogenic influence is evident by studying the deposition of metals towards these areas. Three sampling sites (industrial, urban and rural) were selected to assess the variability in metal deposition. Sampling was carried out monthly (from January 2012 to July 2012) using a bulk (funnelbottle) sampler. As, Cd, Cr, Cu, Mn, Mo, Ni, Pb, Ti, Zn and V were determined in the water-soluble and in the insoluble fractions of deposition samples. The impact of the human activities in the industrial area can be seen on several metals such as Pb, Zn, Cu and Mn. The most obvious influence was found for Mn, high fluxes were measured in the industrial site with a mean value of 2260 µg/m 2 ·day; in contrast to urban (99.6 µg/m 2 ·day) and rural (15.3 µg/m 2 ·day) areas. The lowest flux values were found in the rural area for all the elements. Enrichment Factor (EF) analysis were also studied for the three sites. The high EFs values found for Pb, Mn, Cu, and Zn (>100) in the industrial site point to significant anthropogenic sources, mainly originated from industrial activities (steel and ferro-manganese alloy manufacturing plants) and road traffic.

“…As expected, Mn concentrations measured in ALM and GUAR are higher than the levels found in other Spanish areas affected by steel manufacturing [29], which could be explained by the influence of the nearby ferro-manganese and silico-manganese factory [25,30,31]. The rest of the selected metals are in the range of other Spanish urban sites [29].…”

“…The remaining NH 3 would then react with HNO 3 and HCl to form the nitrate and chloride compounds (Behera et al, 2013 and references therein). The sulfate and nitrate particles could also present in the forms of calcium and magnesium salts (Arruti et al, 2011). Sea salt particles would mainly present in the coarse fraction (Hewitt and Jackson, 2005) hence NaNO 3 , an aging product of sea salt, would mainly be found in the coarse fraction.…”

This study characterized the particulate matter (PM) pollution at a forest site in the Khao Yai (KY) National Park of Thailand, 700 m above sea level and 120 km upwind to Bangkok during the dry season. Two dichotomous samplers simultaneously operated on each monitoring day to collect 2 samples (on 2 filter types: quartz and mix cellulose) of 24 h PM 2.5 and 2 samples of 24 h PM 10-2.5 . More focus was on the dry and more polluted season with a longer sampling period (43 days: Jan-Feb 2005) and less on wet season (10 days, Jun 2005). Samples were analyzed for mass, water soluble ions, elements, EC and OC (Sunset analyzer). PM 2.5 levels obtained at KY in the dry period (47 µg m -3 ) were comparable to those in several urban areas in Southeast Asia, but the wet season levels (7 µg m -3 ) were significantly lower. In the dry season, levels of EC associated with PM 2.5 at KY were remarkably lower than but OC were comparable to those found in urban areas which resulted in considerably low EC/TC ratios (0.08). The major mass groups of PM 2.5 in the dry season were organic matter of biomass smoke origin (OM-smoke), secondary inorganic aerosol, organic matter of other origins than smoke (OM-others) and crustal. Similar contributors to PM 2.5 were also found in the wet season but with only a small contribution from biomass burning smoke. Significant contributions from distant sources to PM 2.5 levels measured at KY were also confirmed by the HYSPLIT backward trajectory analysis. The coarse fraction (PM 10-2.5 ) had major mass groups of OM-others, inorganic particles and crustal that were most likely related to local sources, and some amount of aged sea salt indicating a distant source origin.
