Elemental composition of deposited sediments at the tram-route junction

This data set contains the elemental composition results of deposited sediments collected at the tram-route junction in Gdańsk. Sample collection began in July 2022, when the tram lines were completed and before the rails were scrubbed (27/07/2022). The second sample round was carried out following rail scrubbing in October 2022 (7/10/2022). Since February 2023, the tram line was operational. Subsequent sample campaigns were conducted after one month, three, five, seven, and nine months of operation.
Elements such as Mg, Al, Si, P, S, K, Ca, Cr, Mn, Fe, Co, Ni, Cu, Zn, Cd, and Pb were detected in the collected samples. The multi-elemental composition was determined using non-destructive analytical method: X-ray fluorescence (XRF, Titan S1, Bruker, USA). The certified materials WEPAL ISE 936 and ISE 936 were utilized for method calibration.
