Fig. 1: Spatiotemporal load patterns of pharmaceuticals and viral gene copies in wastewater.

From: Insights into respiratory illness at the population level through parallel analysis of pharmaceutical and viral markers in wastewater

Fig. 1

Wastewater loads from every 13th day between January 2021 and June 2024 are displayed. Data are shown for individual treatment plants according to the abbreviations on the y axis. ZH, Zurich; BL, Basel; BE, Bern; SO, Solothurn; CH, Chur; SZ, Schwyz; GE, Geneva; LA, Lausanne; NE, Neuchâtel; LU, Lugano. These are arranged first by language in the region then by catchment population size. The colouring represents the load values for pharmaceuticals (mg d−1 per 1,000 people) and viruses (gc d−1 per 1,000 people) with linear colour scaling. For pharmaceuticals, each space refers to an individual sample of a particular day, and for the viral loads, each space reflects values from the centred 7-day median. White spaces indicate data exclusions owing to rain-related increases in wastewater volumes exceeding maximum threshold values or owing to the absence of sampling. The black-outlined spaces represent pharmaceutical loads from samples with concentrations below the limit of quantification (LOQ), which are estimated on the basis of half the LOQ value.
