- Transport of perfluoroalkyl acids in a water-saturated sediment column investigated under near-natural conditions.
- Vierke L1, Möller A2, Klitzke S3.Author information 1Federal Environment Agency, Wörlitzer Platz 1, 06844 Dessau-Roßlau, Germany; Leuphana University of Lüneburg, Scharnhorststr. 1, 21335 Lüneburg, Germany. Electronic address: Lena.Vierke@uba.de.2Helmholtz-Zentrum Geesthacht, Max-Planck Str. 1, 21502 Geesthacht, Germany. Electronic address: a.moeller@gba-laborgruppe.de.3Federal Environment Agency, Schichauweg 58, 12307 Berlin, Germany. Electronic address: Sondra.Klitzke@uba.de.AbstractThe aim of this study was to gain an understanding of the transport of C4-10 perfluoroalkyl carboxylic acids (PFCAs) and C4,6,8 perfluoroalkyl sulfonic acids (PFSAs) in a water-saturated sediment column representing a riverbank filtration scenario under near-natural conditions. Short-chain PFCAs and PFSAs with up to six C-atoms showed complete tracer-like breakthrough. Longer chain ones were retarded due to sorption to the sediment or due to other processes in the aqueous phase. The study reports the first column derived sediment-water partition coefficients ranging from 0.01 cm(3) g(-1) to 0.41 cm(3) g(-1) for C4,6 PFSAs and from 0.0 cm(3) g(-1) to 6.5 cm(3) g(-1) for C4,5,6,8,9 PFCAs. The results clearly indicate that short-chain PFCAs and PFSAs may pose a problem if contaminated surface waters are used for drinking water production via riverbank filtration.

- Impact of albuminuria on early neurological deterioration and lesion volume expansion in lenticulostriate small infarcts.
- Umemura T, Senda J, Fukami Y, Mashita S, Kawamura T, Sakakibara T, Sobue G.Author information From the Departments of Neurology (T.U., Y.F., T.S.), Radiology (S.M.), Diabetes and Endocrine Internal Medicine (T.K.), Chubu Rosai Hospital, Nagoya, Japan; and Department of Neurology, Nagoya University Graduate School of Medicine, Nagoya, Japan (J.S., G.S.).AbstractBACKGROUND AND PURPOSE: Albuminuria, a marker of chronic kidney disease, is associated with an increased risk of incident stroke and unfavorable long-term outcomes. However, the association of albuminuria with short-term outcomes and change in infarct volume in patients with acute small subcortical infarction remains unknown.
