Retrospective non-target analysis to support regulatory water monitoring: from masses of interest to recommendations via in silico workflows ArchiMer
Lai, Adelene; Singh, Randolph; Kovalova, Lubomira; Jaeggi, Oliver; Kondić, Todor; Schymanski, Emma L..
Background Applying non-target analysis (NTA) in regulatory environmental monitoring remains challenging—instead of having exploratory questions, regulators usually already have specific questions related to environmental protection aims. Additionally, data analysis can seem overwhelming because of the large data volumes and many steps required. This work aimed to establish an open in silico workflow to identify environmental chemical unknowns via retrospective NTA within the scope of a pre-existing Swiss environmental monitoring campaign focusing on industrial chemicals. The research question addressed immediate regulatory priorities: identify pollutants with industrial point sources occurring at the highest intensities over two time points. Samples from...

The theory of diversification, dating back to the 1930s and the Great Depression, suggests that increasing the variety of industries in a region spreads the risk and reduces the likelihood that all industries will suffer a downturn at the same time. This serves to mitigate the boom and bust pattern often experienced by a heavy reliance on a limited number of industries, which in three of the four western provinces, means natural resource-based industries. This study examines diversification progress in the four western provinces over the last 30 years. The time span covers the greatest progress in trade liberalization policy in the nation’s history, and the evidence...
