title: Alkylsulfonic acid phenylesters (ASEs, Mesamoll®) in dust samples of German residences and daycare centers (LUPE 3).
abstract: For decades, plasticizers have been produced in high quantities to improve the flexibility and durability of products. One possible replacement product is alkylsulfonic acid phenylesters (ASEs), marketed as Mesamoll®. This study aimed to quantify the ASE dust contamination of residences and daycare centers to obtain insight into the recent exposure situation. ASEs were quantified in dust samples collected from 25 residences and 25 daycare centers using GC/MS measurements. Median (95th percentile) values of the sum of tetra- to heptadecylphenylesters are higher in daycare centers, with a value of 19.6mg/kg (216mg/kg), compared to residences, with a value of 7.6mg/kg (171mg/kg). A daily non-dietary intake of 0.08 and 0.86μg/kg b.w., respectively, was observed using the median and 95th percentile values obtained from dust samples. These levels are 1250 and 115 times below a previously set temporary tolerable daily intake value. Nevertheless, the fact that basic data on toxicity and exposure via other pathways are limited or unavailable at present has to be considered.
