Average concentrations of phosphate (a) and nitrate (b) measured in each sampled sub-basins (Level 10 HydroBasins on y axis) in Buenos Aires, Curitiba, Mexico City, Rio de Janeiro, São Paulo and Vancouver.

<p>Bars indicate 2 standard errors (SE).</p

(a) Microscale pollution sources identified by citizen scientists reported as the average sum of each pollution source category per sub-basin averaged by city and (b) percentage of land cover/use recorded by citizen scientists per sub-basin averaged by city.

Receiver Operating Characteristic curve for the phosphate concentration eutrophication threshold of 0.1 mg L^-1 for sub-basins against microscale observations of the sum of pollution sources and macroscale data related to phosphorus loading.
