Vertical distribution of inorganic nanoparticles in a Norwegian fjord
Abstract
<p>Due to the analyticalchallenges of detecting and quantifying nanoparticles in seawater, thedata on distributions of NPs in the marine environment is limited toqualitative studies or by ensemble measurements subject to variousanalytical artifacts. Single particle inductively coupled plasma massspectrometry (SP-ICP-MS) allows determination of individual inorganicNPs at environmentally relevant concentrations, yet only few studieshave been conducted on selected elements in surface sea water. Here, asequential multi-element screening method was developed and implementedto provide a first survey of the horizontal and vertical distributionsof inorganic nanoparticles and trace elements in a pristine Norwegianfjord prospect for submarine tailings deposition. Statistical control offalse-positive detections while minimizing the size detection limit wasensured using a novel raw signal processing. Scanning electronmicroscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) gaveconfirmative and qualitative information regarding particle morphologyand composition. Following SP-ICP-MS screening for particles of 16elements, particulate Al, Fe, Mn, Pb, Si and Ti were found anddetermined to mass concentrations in ng/L of 1–399, 1–412, below limitof detection (<LOD) - 269, <LOD - 1, <LOD - 1981 and <LOD -127 ng/L with particle number concentrations up to 10<sup>8</sup>particles per liter. Total metals concentrations were at least an orderof magnitude higher, at concentrations in μg/L of 1–12 for Al, 2–13 forFe, 0.3–11 Mn, 0.02–0.5 for Pb, 46 to 318 Si and 0.04–0.4 for Ti. Astrong depth dependence was observed for both trace elements andparticles with concentrations increasing with depth. Our results providea baseline for the fjord and new data on environmental levels of bothtotal metals and metal containing nanoparticles including the verticaland horizontal distribution of natural nanoparticles.</p>
