Chemical Element Concentrations in Liepāja Lake (Latvia) Water Samples, August 2024

The dataset represents part of a temporal monitoring program focused on assessing the spatial variability and geochemical characteristics of the lake during the summer stratification period. Water samples were collected from multiple monitoring stations distributed across the lake area, including northern, central, and southern sections.

Sampling depth were 0-20cm and coordinates were recorded for each location. Samples were filtered in the field (0.45 µm) and preserved with ultrapure nitric acid (HNO₃) to pH < 2 for trace element analysis. Concentrations of major and trace elements (Li, B, Na, Mg, Al, P, K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Rb, Sr, Mo) are reported in micrograms per liter (µg/L), accompanied by analytical standard deviations (SD).
