Exploring Metabolic Characteristics in Different Geographical Locations and Yields of L. Using Gas Chromatography-Mass Spectrometry Pseudotargeted Metabolomics Combined with Chemometrics.

The quality of crops is closely associated with their geographical location and yield, which is reflected in the composition of their metabolites. Hence, we employed GC-MS pseudotargeted metabolomics to investigate the metabolic characteristics of high-, medium-, and low-yield (tobacco) leaves from the Bozhou (sweet honey flavour) and Shuicheng (light flavour) regions of Guizhou Province. A total of 124 metabolites were identified and classified into 22 chemical categories.

Impact of green credit policy on sustainability performance of high-pollution enterprises.

Green credit is a financial service that potentially mitigates the impact of environment problems such as climate change, one of the greatest challenges of our time. The effectiveness of a policy that promotes green credit, however, remains controversial. We use China's "Green Credit Guidelines" in 2012 as a quasi-natural experiment to identify the causal impact of green credit policy (GCP) on enterprise sustainability performance (ESP), which integrates the financial and environmental social responsibility performance of heavily polluting firms.
