Effects of chain length and pH on the uptake and distribution of perfluoroalkyl substances in maize (Zea mays)
•Chain length-dependent uptake of PFASs by maize roots.•High uptake and translocation of short-chain PFASs by maize.•Short-chain PFASs are transferred predominantly to the shoot (shoot:root ratio>2).•Long-chain PFASs are transferred predominantly to the root (shoot:root ratio2.0, which indicates...

Maize is the most important grain crop grown for human nutrition, animal fodder and biogas production worldwide. Nonetheless, no systematic studies have been undertaken on these plants to examine the uptake mechanisms for perfluoroalkyl substances (PFASs) dependent upon chain length and pH value. The aim of the present study was therefore to determine the influence of chain length (C4 to C10) and pH value (pH 5, pH 6, pH 7) on the uptake and distribution of seven perfluoroalkyl carboxylic acids (PFCAs) and three perfluoroalkane sulfonic acids (PFSAs) by maize in nutrient solution experiments under controlled conditions in a climate chamber. A pH-dependent uptake was observed for perfluorodecanoic acid (PFDA) with an uptake rate of 2.51μgg−1 at pH 5 compared to 1.52μgg−1 root dry weight (DW) per day (d) at pH 7. Perfluorobutanoic acid (PFBA) had the highest uptake rate within the group of PFCAs with an average of 2.46μgg−1 root DWd−1 and perfluorooctane sulfonic acid (PFOS) had the highest uptake rate (3.63μgg−1 root DWd−1) within the group of PFSAs. The shoot:root ratio for shorter-chain PFCAs (⩽C7) and PFBS (C4) was >2.0, which indicates that shorter-chain PFASs are transferred predominantly and at higher concentrations to the shoot. In contrast, long-chain PFCAs such as perfluorooctanoic acid (PFOA), perfluorononanoic acid (PFNA) and perfluorodecanoic acid (PFDA) as well as the PFASs perfluorohexane sulfonic acid (PFHxS) and perfluorooctane sulfonic acid (PFOS) accumulated at higher concentrations in the roots of maize plants with a shoot:root ratio of <1.0.</description><identifier>ISSN: 0045-6535</identifier><identifier>EISSN: 1879-1298</identifier><identifier>DOI: 10.1016/j.chemosphere.2013.09.018</identifier><identifier>PMID: 24095614</identifier><identifier>CODEN: CMSHAF</identifier><language>eng</language><publisher>Kidlington: Elsevier Ltd</publisher><subject>Absorption.
