Cover Story: The global rise in pesticide usage poses significant risks to non-target aquatic organisms, as surface water contamination becomes a pressing environmental concern. Monitoring emerging pesticides in surface waters is critical due to their toxicity and the absence of consistent surveillance. This research addresses the need for advanced analytical methods to detect newly registered fungicides in surface waters. A robust and efficient method employing QuEChERS-based UHPLC-MS-MS has been developed and validated, capable of detecting several emerging fungicides at trace levels. Applied in the Greater Melbourne Area, this method has, for the first time in Australia, identified and quantified these compounds emphasizing their persistence in aquatic environments.
