“…In this study, the concentrations of elements in the local soil were calculated based upon the average composition across the Guizhou Province. In enrichment factor analysis Fe, Ti, and Al are typically used as reference elements (Nováková et al 2016;. For this study Ti was chosen as the reference element for calculating enrichment due to its stability and its propensity to be less susceptible to deterioration, alteration, and weathering.…”

The increasing emission of primary and gaseous precursors of secondarily formed atmospheric particulate matter due to continuing industrial development and urbanization are leading to an increased public awareness of environmental issues and human health risks in China. As part of a pilot study, 12-hr integrated fine fraction particulate matter (PM 2.5 ) filter samples were collected to chemically characterize and investigate the sources of ambient particulate matter in Guiyang City, Guizhou Province, southwestern China. Results showed that the 12-hr integrated PM 2.5 concentrations exhibited a daytime average of 51 ± 22μg•m −3 (mean ± standard deviation) with a range of 17-128μg•m −3 and a nighttime average of 55 ± 32μg•m −33 with a range of 4-186 μg•m −3 . The 24-hr integrated PM 2.5 concentrations varied from 15 to 157 μg•m-3, with a mean value of 53 ± 25 μg•m −3 , which exceeded the 24-hr PM 2.5 standard of 35μg•m −3 set by USEPA, but was below the standard of 75μg•m −3 , set by China Ministry of Environmental Protection. Energy-dispersive X-ray fluorescence spectrometry (XRF) was applied to determine PM 2.5 chemical element concentrations. The order of concentrations of heavy metals in PM 2.5 were iron (Fe) > zinc (Zn) > manganese (Mn) > lead (Pb) > arsenic (As) > chromium (Cr). The total concentration of 18 chemical elements was 13 ± 2 μg•m −3 , accounting for 25% in PM 2.5 , which is comparable to other major cities in China, but much higher than cities outside of China.

“…Heavy metals in soils came from natural and man-made sources, the former mainly originate from natural geochemical processes, such as rock and mineral weathering, while the latter originate from industrial and agricultural production and domestic activities (Wei et al, 2016;Gao et al, 2016;Han et al, 2016). General metal mineral mining, smelting, waste incineration and landfill, fertilizer production and using pesticides could cause direct or indirect heavy metal contamination, leading to the eventual accumulation in the wider environment (Babek et al, 2015;Dung et al, 2013;Novakova et al, 2016). The I geo method reflects the nature of the heavy metal distribution characteristics and allows us to distinguish the environmental impact by human activities.…”

Soil heavy metal contents were measured in newly submerged areas of the Danjiangkou Reservoir, China. We aimed to determine the heavy metal distribution in this area and the associated ecological risk. Most of these heavy metal contents (except Pb and Mn) suggest enrichment compared with the background values of soils from Henan Province, especially As and Cd with mean geo-accumulation index (I) values of 0.84 and 0.54. The spatial analysis results indicated that the highest heavy metal contents were distributed in the arable soils above 160m elevation, whereas low heavy metal contents were observed under other land-use types above 160m elevation. According to I and EF values, Cd was the major heavy metal contaminant in the newly submerged area, Cr, Pb and Mn mainly originated from natural geochemical sources. In contrast, Ni, Cd, As, Cu, and Zn mainly originated from anthropogenic sources. Evaluation using the potential ecological risk (PER) method indicated that PER of individual elements were low in the studied soils, and the comprehensive PER index was at a moderate level, indicating heavy metals in the soils of newly submerged areas may not threaten the water quality of Danjiangkou Reservoir, especially in winter.

Humans have considerably influenced accumulation rates and sediment composition in lake deposits. Due to near‐continuous accumulation, lakes and reservoirs are an excellent archive of these anthropogenic influences. The Urft Reservoir in the Eifel Mountains, western Germany, provides a unique record of the human influence on the landscape for the past 115 years. In 2020 and 2021, 24 cores and 23 surface samples were obtained from the bottom of the, by that time drained, reservoir. Grain size, heavy metals, weathering signatures and microplastic were analysed. For the chronology, caesium‐137 and microplastic were used. Using the first occurrence of microplastic as well as different plastic types for dating was not successful. However, a distinct layer with a high number of microplastic particles could be traced back to a fire in 1991 and was used as an additional stratigraphic marker in the age‐depth model. A period of relatively high accumulation rates in the reservoir occurred in the mid‐1950s and was related to enhanced construction works in the local valleys. Analysis of heavy metal content in the reservoir sediments shows a strong connection to historical changes in ore industry in the valley of the Urft. Stricter environmental protection laws and the decline of the metal processing industry resulted in a reduced input of lead, copper and zinc in the reservoir until the mid‐1980s. Since then, heavy metal content has remained relatively constant. A major flooding event in July 2021 did not lead to the remobilisation of older contaminated deposits as indicated by low heavy metal content in flood deposits. Accordingly, also the microplastic content is not increasing following the extreme event. Due to the degree of weathering of the flood deposits, it is argued that mainly hillslope material was transported into the Urft and subsequently into the Urft Reservoir during this event.
