China has made great efforts to fight environmental contamination along with rapid development and industrialization over the past few decades. However, the effects of these nationwide measures, such as energy restructuring, on pollutant residuals in soil have not been well quantified. Polycyclic aromatic hydrocarbon (PAH) pollution is a major concern around the world, and PAH emissions are associated with the energy structure. Therefore, we speculated that the adjustment of the energy structure in China may reduce the content of PAHs in soil. To test this hypothesis, we measured the concentrations of sixteen US Environmental Protection Agency (US EPA) priority PAH compounds (Σ16PAHs) at 54 soil sampling sites in Beijing in 2008 and 2019 and compiled nationwide data for 1704 soil sampling sites in the past two decades. The results showed that the Σ16PAH concentrations descended along the urban–suburban–rural–background gradient, and they first increased with increasing gross regional production (GRP) and plateaued when the GRP reached a certain level. The average Σ16PAH concentrations showed a decreasing trend across China over the past 20 years, and they decreased significantly from 22.7 μg·g−1 total organic carbon (TOC) in 2008 to 10.0 μg·g−1 TOC in 2019 in Beijing. The source identification analyses inferred that the decreasing trend of soil PAHs was due to the declines in the consumption of coal, coke, and some oils and the rising consumption of clean energy, such as electricity and natural gas, in China. This study demonstrates the important role of adjusting the energy structure in decreasing soil PAH concentrations and improving soil environmental quality.

Crossing “Environmental Mountain”——On the Increase and Decrease of Environment Impact in the Process

The curve of environmental impact in the process of economic growth in developed countries was likened to “environmental mountain”. For developing countries, particularly China, the right way of economic development is going through the “environmental mountain” on the halfway up the mountain - a new way for industrialization. The formulas of the relationship between environmental impact and GDP were derived, in which there are 2 key variables: g—growth rate of GDP; t—decreasing rate of environmental impact per unit GDP. Taking several countries and provinces in China as examples, the relationships between economic growth and energy consumption were studied. The environmental impacts of China in the years 2005, 2010 and 2020 were anticipated under different assumptions, and further discussion was given in terms of energy consumption.
