Résumé
Pipe scales that form in drinking water distribution systems (DWDS) can accumulate pollutants that may be re-released into bulk water, posing a significant threat to water safety. This study aims to evaluate the pollutant enrichment capacity of the pipe scale and identify speciation changes in heavy metals under variations in water quality. When the water quality conditions changed, the forms of inorganic metal elements in drinking water pipe scales also changed and the proportion of unstable forms increased, thereby increasing the risk of secondary pollution. Morphological analysis showed that the pipe scale samples had porous structures and large specific surface areas (the maximum was 52.94 m
