TL;DR: Analytical electron microscopy revealed that TiO(2) particles are detached from new and aged facade paints by natural weather conditions and are then transported by facade runoff and are discharged into natural, receiving waters.

TL;DR: Results from batch experiments suggested that Ag-NP transformation to Ag(2)S occured in the nonaerated tank within less than 2 h, which must be considered in future risk assessments.

TL;DR: Microscopic results indicate that the Ag-NP are likely transformed to considerably less toxic forms such as Ag2S.

TL;DR: Ag-NP discharged to the wastewater stream will become sulfidized to various degrees in the sewer system and are efficiently transported to the WWTP, but primarily depending on the size the Ag-NP, may not be complete.

TL;DR: Investigation of silver nanoparticles in a sludge-amended soil cultivated with monocot and dicot crop species shows that Ag was preferentially associated with S-rich particles, including organic fragments, of the sludge and amended soils, and Nano-XRF evidenced the presence of mixed metallic sulfides.
