“…In the catchment, the river water area only accounts for 0.72% of the basin area [36] and the direct Mo input to the river water through rainwater and atmospheric dust is far less than the Mo input to the soil. Moreover, the Mo content of the rainwater and atmospheric dust of karst region [37][38][39][40] are also relatively lower than that of economy developed region, such as the acid precipitation zone of southern China [41], Yangtze River Delta [42], Beijing [43], Chang-Zhu-Tan production region [44] and the Asian dust [45]. Consequently, we conclude that the effect of atmospheric input on Mo concentration in river water is limited and the influence on δ 98/95 Mo is negligible.…”

The dissolved molybdenum (Mo) contents and Mo isotope in water samples from the upper Xijiang River (XJR), draining the carbonate terrain, southwest China, are reported to investigate the seasonal and spatial variations, sources, ion budget, and isotopic fractionation of dissolved Mo. The results show that the Mo concentrations (5.3–18.9 nmol/L) exhibit an extensive variation along the mainstream without significant spatial pattern, but the Mo concentrations are slightly higher in the dry season than in the wet season caused by the dilution effect. There is a slight spatial tendency for δ98/95Mo to become higher along the mainstream (0.51–1.78%), while the seasonal variations in δ98/95Mo values of NPR (Nanpanjiang River) reach and BPR (Beipanjiang River) reach can be identified higher in the dry season but lower in the wet season. Based on the hydro-geochemical analysis, the sources of dissolved Mo are identified as the carbonates and sulfide/sulfate minerals weathering with a seasonal contribution. Moreover, our results suggest there is no significant Mo isotopic fractionation during weathering and riverine transportation. The calculation of Mo budget demonstrates that the dissolved δ98/95Mo of river draining the carbonate terrain is underestimated, which could significantly influence the redox history of oceans by Mo isotope model.

“…We adopted a newly revised tracking method to estimate the contribution of deposition from related external sources in the Gannan County area to the overall deposition. Previous studies have determined that the ideal tracer between in-situ and external sources should be stable in the inner and outer regions of the study area [30][31][32][33][34][35]64,81]. Moreover, the fingerprint spectrum should be relatively stable and discriminating during the migration process [82,83].…”

“…Geochemical and Lagrangian back-trajectory analyses were used to evaluate the characteristics of trace elements in atmospheric dry deposition in the Gannan County area of Northeast China. According to the dry deposition flux, the degree of atmospheric pollution of Cd, Hg, Cr, Ni, Pb, As, Cu, Mn, and Zn was lower in the study area than in Beijing, Hebei, and the Chengdu Economic Zone [34,63,64]. However, the levels of Ni, Pb, Zn, and other elements were higher than in Northern France, Lake Erie, and other regions [73][74][75][76][77][78][79][80].…”

“…East Asian deserts are the second largest source of dust [19,28]. The Taklimakan desert and the deserts of Inner Mongolia (such as Badain Jaran and Tengger) are the dominant dust sources for both the subarctic Northwestern Pacific, Greenland and even North America [25,29] Although system model research studies of dry deposition have been conducted [1,2,11,25,[30][31][32][33][34], most of the investigations have been limited by the multiple solutions of the algorithms, which analyze the source information based on the pollution transmission of meteorological conditions or lack information on the geological compositions of particles, which could provide accurate source information [35][36][37][38]. In addition, research on the isotopes of dry deposition particles has revealed significant new information.…”

A New Geochemical Method for Determining the Sources of Atmospheric Particles: A Case Study from Gannan, Northeast China

The geochemical characteristics of atmospheric deposition can help trace the origin and assess the impacts of pollutants. Northeast China has always been a region seriously affected by sandstorms. This study aims to explain the potential source of sandstorms in Gannan County, Heilongjiang Provence, by collecting dust and analyzing geochemistry in one year where there is no significant industrial or anthropogenic pollution. Input fluxes of deposition show that Zn and Mn were more prevalent (36.7 g·hm−2·a−1 and 77.93 g·hm−2·a−1, respectively) than other elements. The geochemical composition of atmospheric deposition samples from 17 collection points in Gannan County were determined with regard to 20 elements including nine heavy metals, two metalloids, three nonmetallic elements, a transition metal, and five other major elements. The discriminate function (DF) and chemical index of alteration (CIA) indices indicate that Gannan County (agricultural production area) and Harbin (densely inhabited district) have similar geochemical characteristics of dry deposition. The integration of Na/Al and Ca/Mg ratios with an air mass back-trajectories model shows effects from Russian dust sources (36.6%) and from the northwest desert of China (13.3%). The results will assist in developing strategies for reducing dry deposition pollution inputs to agricultural soils in the area and will effectively target policies to protect soils from long-term contaminant accumulation.
