Comparison of ice abundances (relative to H₂O) toward low- and highmass protostars. The abundances toward the IRAS 18089 mm analyzed in this work is shown in blue. The results for the low-mass protostars B1-c (red) and IRAS 2A (orange) were taken from Chen et al. (2024). The high-mass protostar IRAS 23385 (green) and MIR peak of IRAS 18089 (pink) were analyzed in Rocha et al. (2024) and van Dishoeck et al. (2025), respectively. The ST6 source located in the LMC was studied by Sewiło et al. (2025) and is shown in purple. Upper limits are indicated by gray bars and triangle data points.
