Submicron soot particles (with an aerodynamic diameter of less than 1.0 μm) are found to be one the major factors resulting in global warming and health burdens. However, research on biomonitoring submicron their associated sources using tree leaves has not been comprehensively conducted. This study investigated seasonal trends seven types collected from four individual seasons across two years Nanjing, Yangtze River Delta region China, performed source apportionment stable carbon isotope analysis. Significant variations were observed types, with average levels 0.3 0.5 mg m−2 during summer 1.3 winter. The varied significantly various types. In contrast, δ13C change different ranged −26.3‰ −20.9‰ winter −24.0‰ −18.1‰ summer, fossil fuels accounting for 56% 78% average, respectively. These results demonstrate that can serve as a low-cost effective tool assessing status soot.
