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: Sources and pathways of additives used in construction materials, i.e., biocides in facades' render as well as root protection products in bitumen membranes for rooftops are investigated, showing the impact of construction materials containing hazardous additives on water quality is related clearly to the age of the buildings and the separated sewer network.

TL;DR: The following field study correlates wind driven rain to runoff and measured the release of several commonly used organic biocides in organic façade coatings from four coating systems.
