Methods for evaluating total oil and grease in water

This paper explores the correlation between the volume of scholarly publications on methodological approaches to total oil and grease (TOG) in wastewater and the implementation of public policies from 1970 to 2023, catalysed by resolutions adopted under the auspices of the United Nations. This period coincides with the emergence of global concerns about climate change and environmental protection. The analysis highlights a steady increase in publications, with research trends closely mirroring policy shifts. Initial studies in the 1970s laid the groundwork for subsequent research, as major global conferences and regulatory changes consistently spurred new publications. Notably, 68.75 % of the reviewed literature was published in the last decade, with nearly 40 % published in the past 2.5 years—reflecting the topic's sustained and increasing relevance.
