- ... The UV-filter substance Sulisobenzone (BP-4) is widely employed in sunscreens and other personal care products. In the current study, its behavior during biological wastewater treatment was investigated. In contact with activated sludge BP-4 was degraded in aerobic batch experiments forming at least nine transformation products (TPs). The mass balance in the batch experiments was closed, as measur ...

- ... The transformation of the iodinated X-ray contrast media (ICM) iopamidol, iopromide, iohexol, iomeprol, and diatrizoate was examined in purified water over the pH range from 6.5 to 8.5 in the presence of sodium hypochlorite, monochloramine, and chlorine dioxide. In the presence of aqueous chlorine, only iopamidol was transformed. All other ICM did not show significant reactivity, regardless of the ...
