“…The minimum value was revealed by a sample taken on May 8 th 2011. Compared with the previous report on δ 34 S values of SO 4 2− in the precipitation from other cities, the average δ 34 S value of Beijing precipitation was higher than that of precipitation from Guiyang (−2.8‰; Xiao et al 2011a), Zigui (+2.1‰; Wu and Han 2015), Nanchang (+2.1‰; Xiao et al 2011b), and Seoul (+3.7‰; Lim et al 2014). The δ 34 S value of sulfate in precipitation in Xi'an was reported in the range of +8.71 to +19.05‰ with a mean value of +13.41±2.35‰ (Bai and Wang 2014), which was significantly higher than the sulfur isotope value in this study.…”

China is experiencing serious acid rain contamination, with Beijing among the worst-hit areas. To understand the chemical feature and the origin of inorganic ions in precipitation of Beijing, 128 precipitation samples were collected and analyzed for major water-soluble ions and δ 34 S. The pH values ranged from 3.68 to 7.81 and showed a volume weighted average value (VWA) of 5.02, with a frequency of acid rain of 26.8 %. The VWA value of electrical conductivity (EC) was 68.6 μS/cm, which was nearly 4 times higher than the background value of northern China. Ca 2+ represented the main cation; SO 4 2− and NO 3 − were the dominant anion in precipitation. Our study showed that SO 4 2− and NO 3 − originated from coal and fossil fuel combustion; Ca 2+ , Mg 2+ , and K + were from the continental sources. The δ 34 S value of SO 4 2− in precipitation ranged from +2.1 to +12.8‰ with an average value of +4.7‰. The δ 34 S value showed a winter maximum and a summer minimum tendency, which was mainly associated with temperature-dependent isotope equilibrium fractionation as well as combustion of coal with relatively positive δ 34 S values in winter. Moreover, the δ 34 S values revealed that atmospheric sulfur in Beijing are mainly correlated to coal burning and traffic emission; coal combustion constituted a significant fraction of the SO 4 2− in winter precipitation.

“…Isotope approaches as complementary tools to chemical composition of precipitation have already proven their added value to identify the origin of pollutants (e.g. Caron and Tessier 1986;Lee et al 2012;Xiao et al 2012;Lim et al 2014). Similar approaches have already been used for characterising precipitation in Wroclaw (SW Poland) (Górka et al 2008;Szynkiewicz et al 2008;Górka et al 2011).…”

“…Sulphur isotope ratios can be used to track fossil fuel burning and to trace the sources of pollution because, as with lead isotopes, natural and anthropogenic sources often have different isotope ratios (e.g. Krouse et al, 1984;Lim et al, 2014). Sulphur released into the atmosphere has the potential to cause acid rain.…”

We consider whether the Anthropocene is recorded in the isotope geochemistry of the atmosphere, sediments, plants and ice cores, and the time frame during which any changes are recorded, presenting examples from the literature. Carbon and nitrogen isotope ratios have become more depleted since the 19th century, with the rate of change accelerating after ~ad 1950, linked to increased emissions from fossil fuel consumption and increased production of fertiliser. Lead isotope ratios demonstrate human pollution histories several millennia into the past, while sulphur isotopes can be used to trace the sources of acid rain. Radioisotopes have been detectable across the planet since the 1950s because of atmospheric nuclear bomb tests and can be used as a stratigraphic marker. We find there is isotopic evidence of widespread human impact on the global environment, but different isotopes have registered changes at different times and at different rates.
