Micro-distribution of arsenic and polycyclic aromatic hydrocarbons and their interaction in Pteris vittata L.

Atomic Spectrometry Update: review of advances in elemental speciation

“…Two groups have reported work on the hyperaccumulator fern Pteris vittate . The interactive effects of iAs species and PAHs on their uptake, accumulation and translocation have been studied hydroponically by Liao et al 49 The presence of PAHs hindered As uptake and acropetal translocation by P. vittata , decreasing As concentrations by 29.8 to 54.5% in pinnae, regardless of the initial As speciation. The inhibitive effect of PAHs was 1.6 to 8.7 times greater for As III than for As V .…”
