[17]. Only fiberswere encountered and fragmentswere not detected. Throughout
the year of monitoring (site 1), the atmospheric fallout ranged from 2 to
355 fibers m 2 day 1 (110 96 fibers m 2 day 1, mean SD), indicating a
high annual variability. On site 2, the atmospheric fallout was estimated around
53 38 fibers m 2 day 1. When the levels on both sites are compared, the
suburban site systematically showed fewer fibers than the urban one.We hypo-
thesize that this difference can be explained by the density of the surrounding
population,which isconsideredasaproxyof localactivity.However, thishas tobe
confirmed through investigations at other sites.
A suburban catchmentwith a separate sewer (wastewater and runoffwater are
collected separately)was considered for the urban runoff (unpublished data). The
Sucy-en-Brie (R1, Fig. 1) catchment area reaches 261 ha, and its impervious
