“…This figure was calculated for the entire method including acid digestion. Although no studies have calculated measurement uncertainty specifically for tyre analysis, the value of 12.6% is comparable to other expanded uncertainty estimates made for ICP-MS methods (7.7% to 13.6% for metals in drinking water, (Tanase et al, 2015)), and allows for individual results to be reported with the expanded uncertainty of the method.…”

The purpose of this study was to identify a characteristic elemental tyre fingerprint that can be utilised in atmospheric source apportionment calculations. Currently zinc is widely used as a single element tracer to quantify tyre wear, however several authors have highlighted issues with this approach. To overcome this, tyre rubber tread was digested and has been analysed for 25 elements by ICP-MS to generate a multielement profile. Additionally, to estimate the percentage of the tyre made up of inert fillers, thermogravimetric analysis was performed on a subset. Comparisons were made between passenger car and heavy goods vehicle tyre composition, and a subset of tyres had both tread and sidewall sampled for further comparison. Finds showed 19 of the 25 elements were detected in the analysis. The mean mass fraction of zinc detected was 11.17 g/kg, consistent with previous estimates of 1% of the tyre mass. Aluminium, iron, and magnesium were found to be the next most abundant elements, and barium, magnesium and tin were all detected at higher concentrations than have been reported previously. The analysis found significant differences in elemental composition of goods vehicle and passenger car tyres, which could potentially allow for separate source profiles for each type. Only one source profile for tyre wear exists in both the US and EU air pollution species profile databases, highlighting the need for more recent data with better coverage of tyre makes and models. This study provides data on new tyres which are currently operating on-road in Europe and is therefore relevant for ongoing atmospheric studies assessing the levels of tyre wear particles in urban areas.

“…In comparison with these sophisticated MS techniques, quadrupole based ICP-MS (ICP-QMS) has the advantages of low analysis cost, simple operation, instrument robustness, and simple sample preparation, but has poorer precision (0.2-1.0%). 19,[37][38][39][40][41] Bandura et al reported that collisional damping by a non-reactive gas (Ar or Ne) in a dynamic reaction cell (DRC) resulted in improved precision of Pb and Ag isotope ratios determinations (0.03-0.1%). 42 They also demonstrated that collisions with non-reactive gas molecules increased the average residence time of analyte ions in the cell and that ions sampled at slightly different moments in time were actually mixed.…”

In this contribution, we outline the estimation of measurement uncertainty of analytical assays in a practical way, according to the so-called reconciliation paradigm, by considering the heritance of uncertainties according to the ISO Guide to the expression of uncertainty in measurement (ISO/GUM) approach and the accuracy (bias and precision) study coming from the in-house method validation. A cause and effect analysis is performed by using the Ishikawa diagram or fishbone plot, consisting of a hierarchical structure reaching a final outcome that is the analytical result. The procedure is illustrated with a case study. This procedure may be very suitable for processing data in accreditation of routine assays.
