Description
M Ferrari and co-authors present a 2026 journal article tracing river chemistry along the Greve River in Tuscany, Italy, during the extreme 2022 European drought and the heavy rain that followed. The river runs from countryside into urban Florence's orbit, gathering pollution downstream. Six sampling campaigns between May and October 2022 combined chemical and isotope tracers.
Downstream water grew richer in human tracers such as nitrate, up to nine milligrams per liter, and potassium. In the driest months, isotope patterns showed strong evaporation stress. The first intense rain then flushed accumulated material downstream in a rapid, uneven pulse, with ammonium peaking in urban sectors. The authors frame tracer monitoring as a transferable way to judge river vulnerability under climate extremes.
