“…Poor air quality can affect our health because fine particles are carried deep into the lungs during the breathing process. Certain pollutants contribute to acid rain by affecting soils and vegetation [1,2]. Many studies show that air pollutants, in particular particulate matter (PM), contribute to the occurrence or exacerbation of symptoms of many diseases, including upper respiratory tract disease, asthma, chronic obstructive pulmonary disease (COPD), pneumonia, and cardiovascular disease.…”

The coronavirus disease (COVID-19) has caused huge changes in people’s daily habits and had a significant impact on the economy. The lockdowns significantly reduced road traffic and meant that many people worked remotely. Therefore, the question arose as to how the reduced road traffic and stays of residents at home affected the degree of pollution and the structure of major air pollutants. To answer this question, the article presents an analysis of changes in typical air pollutants (PM10, PM2.5, NO2) in the five largest Polish cities and one of the voivodships. The data from the Polish State Environmental Monitoring were used for the analysis. The analysis showed that the period of the first lockdown in Poland (April 2020), despite the reduced road traffic, resulted in a significant increase in PM10 emissions (9–91% during working days and an average of 30% on Saturdays and Sundays), a slight increase in PM2.5 emissions (on average from 2% to 11% for all analyzed locations), and a reduction in NO2 emissions (on average from 6% to 11% for all analyzed locations) compared to the period before the lockdown. However, the changes were not homogeneous—in Łódź and Warsaw, in most cases, an increase in all analyzed pollutants was observed, and the greatest decrease in pollution took place in Małopolska voivodship (including Kraków). Comparing the data from April 2020 to the data from April 2019, the overall difference in the PMs concentrations was small, although there are places where there has been a significant decrease (Wrocław, Poznań), and there were also places where the concentration increased (Warsaw, Łódź, Małopolska). In the case of nitrogen dioxide, pollution concentration decreased in most locations. The only exception was the background stations in Warsaw, where the increase was 27%.

“…Sulfur retention in soil is of crucial importance for preventing cation loss and aluminum mobilization and thus the acidification of soil and surface water (Likens et al., 1996; Mulder et al., 1989; Neary & Dillon, 1988; Stoddard et al., 1999). Although China received chronically elevated atmospheric S deposition with the increase in SO 2 from 6.8 in the 1980s to 34 Tg yr −1 in 2006 (Duan et al., 2016; Yu & Duan, 2020), the substantial S retention in subtropical China (∼80% of total S deposition) has partly alleviated the acidification in recent decades. Compared to the temperate forests in Europe and North America, light surface water acidification in China was observed as a result, even under heavy deposition (Yu et al., 2017a).…”

“…Numerous studies have documented that desorption of adsorbed S would occur in light of a continuous decline in atmospheric S deposition, which has been reported to delay the recovery of soil and water acidification in America and Europe (Likens et al., 1996; Rice et al., 2014; Stoddard et al., 1999; Wright et al., 1988). The results derived from monitoring and modeling showed a sharp decline in S deposition in China recently, with the decline in national SO 2 emissions (Duan et al., 2016; Yu & Duan, 2020). Consequently, a delayed decline in sulfate export from the watersheds could be expected considering the large adsorbed

The sulfur biogeochemical cycle controls the sulfur dynamics in the soil. In contrast to almost all deposited sulfur leaching out in temperate catchments, approximately 80% of the deposited S is retained in the catchments in subtropical regions. However, the mechanisms for sulfur retention were unclear, hindering the understanding of potential threats of legacy sulfur with environmental changes. Here, we demonstrated that sulfate reduction (as sulfide fixed in soil) was a prominent yet overlooked mechanism for sulfur retention in addition to the widely recognized sulfate adsorption in soil, based on a study on soil sulfur storage and stable isotope signatures within entire soil profiles in a typical subtropical catchment in China. Using a dual‐isotopic model, the sulfate reduction flux was further determined to be 30% of the S deposition. Due to a lot of deposited sulfur fixed via sulfate reduction, the release of soil legacy sulfur would be less in response to decreasing sulfur deposition compared to the projections only considering adsorption. However, the remobilization of large amounts of reduced S should be regarded as a threat to the environment under climate change in the future.

Sulfur budgets in catchments indicated that about 80% of the deposited sulfur was retained in the subtropical soil, it alleviates the historical acidification caused by elevated deposition. The strong sulfur retention was attributed to the reversible sulfate adsorption in previous studies. Here we report that sulfate reduction is a prominent yet thus far overlooked mechanism for sulfur retention, based upon the comprehensive evidence of soil sulfur storage and multi-isotope within entire soil profile along a hydrological continuum in a typical subtropical catchment of China. Using a dual isotopic mass balance model, we determined that annual flux of reduction accounted for approximately 38% of sulfur retention, which was close to the proportion of reduced species in soil. Consequently, the release of sulfur legacy would be less serious with the decreasing sulfur deposition in China, compared to the projections only considering adsorption.
