Article Synopsis
- The paper examines the transition from pandemic to endemic spread of influenza by analyzing data from the 1918/19 flu pandemic in Bern, Switzerland, focusing on both spatial and temporal patterns of infection.
- It utilizes extensive reports to calculate incidence rates across municipalities and employs mapping techniques to illustrate the fluctuations in case numbers over multiple waves from summer 1918 to 1924.
- Findings indicate that the spread varied significantly by locality, with industrial areas experiencing higher incidences during the first wave, highlighting the importance of environmental factors in disease transmission.
In order to distinguish between aerobic biodegradation of synthetic polymers in fresh and seawater, polyethylene glycols (PEGs) were systematically and comparatively investigated in inocula from municipal wastewater and seawater aquarium filters for the first time. The molecular weight (MW) of the PEGs, (HO(CH(2)CH(2)O)(n)H, n=3-1350) as representatives of water-soluble polymers, ranged from 250 to 57,800Da. The biodegradation was observed by removal of dissolved organic carbon and carbon dioxide production by applying standardized ISO and OECD test methods.

The investigated P(3) are relevant representatives or metabolites from the compound classes: pesticides, pharmaceuticals, insect repellents, flame retardants and anionic surfactants. Analyses of all these P(3) at low ng L(-1) levels with sufficient standard deviations was performed in WW influents and effluents.
