“…The changes above are similar to many other Pb isotope studies in China, those suggest that the changes were mainly related to anthropogenic Pb inputs (Liu et al, 2013;Yu et al, 2016;Zhang, et al, 2016). In combination with the synchronous increases in EFs and anthropogenic fluxes, it is reasonable to infer that the above Pb isotope changes were caused by increased inputs of anthropogenic Pb in recent decades.…”

According to sedimentary records from China covering the last millennia, it was suggested that anthropogenic Pb pollution occurred hundreds or even thousands years ago related to mining and metallurgy, such as in Lake Liangzhi since ~3000±328 BC in central China (Lee et al, 2008) and in Lake Erhai from 1100 to 1300 AD in southwest China (Hillman et al, 2015).…”

Sedimentary records from remote regions contain pollutants derived dominantly from atmospheric input, and thus have the potential to trace past atmospheric pollution history. Based on seventeen sediment records from relatively remote areas of China, atmospheric Pb pollution history during the last century was studied. These records suggest some slight pollution before ~1950 and display synchronous Pb enrichment processes since the 1950s, implying the start of widespread atmospheric Pb pollution in China. This corresponded well with the beginning of socio-economic development after the establishment of the People's Republic of China. However, owing to the Chinese Cultural Revolution, a roughly unchanged atmospheric Pb status was found in the 1960-70s except on the Qinghai-Tibetan Plateau, where atmospheric Pb still increased gradually caused by long-range atmospheric transport of pollutants from southwest Asia. In ~1980-2000, atmospheric Pb experienced the greatest increase, resulting from rapid development of extensive economy after the Reform and Openingup in 1978. After ~2000, atmospheric Pb generally stopped increasing due to the phasing out of leaded gasoline, but it remained high, with the highest in Southwest China, medium in Northeast China, central North China and the Qinghai-Tibetan Plateau, and the lowest in the southeast Mongolia Plateau and West China. This study reveals spatio-temporal variations of atmospheric Pb in inland China under the influence of recent human activities, providing an important supplement for understanding global Pb pollution in the Anthropocene.

“…A mixed linear model is established from the Pb isotope ratio in order to trace the sources of Pb pollution and determine their relative contributions [18,45]. According to the results of the principal component analysis (see below), Pb in farmland topsoils can be assessed as having three components, which can be further explored by using the ternary linear model of the Pb isotope.…”

Cd and Pb in farmland topsoil are controlled by many factors. To identify the source of potential toxic metals in the farmland topsoil around Mianyuan River, the chemical analysis and multivariate statistical analysis are performed in this study. The results indicate the following: (1) The concentration of Cd and Pb in soil exceed the background value of Chinese soil elements. (2) Cd is significantly enriched in the whole region and Pb is locally enriched, both of them are more or less influenced by human activities. (3) The contents of Cd and Pb increase significantly following the flow direction of river. (4) Pb isotope analysis indicates that the main source of Pb in the soil include the air dust, coal and phosphate plant, and the contribution of them decreases successively. (5) Linear correlation analysis and principal component analysis show that the main sources of Cd in the soil are mining phosphate rock, air dust, phosphate plant and coal mining.
