Description of key information
Adverse effects on the root length and the number of lateral roots of Pinus banksiana was observed after 42 days of exposure to 1.4 g/L solution of sodium sulfate.
Key value for chemical safety assessment
Additional information
Croser et al. (2001) studied the toxicity of sodium sulfate to three coniferous species (Picea glauca, Pinus banksiana and Picea mariana) following the application of increased sodium sulfate concentrations, 0, 10, 20, 50, 100 and 250 mM to surface of trays containing seeds . The method was not standardized, however it was described and the parameters (seed germination, survival, biomass, injuries on shoots and roots) are the same as those in the OECD 208 Guideline “Seedling Emergence and Seedling Growth Test”. This publication was considered as Klimisch 2, valid with restrictions. Amongst the three species tested, Pinus banksiana appeared to be the most sensitive to sodium sulfate with adverse effect on the root length and the number of lateral roots affected at 10 mM (1.4 g/l) of the applied solution. For the other species, adverse effects were observed at the higher concentration of 20 mM (2.8 g/L). Since the quantity of sand was not reported, it is not possible to calculate the sand concentrations of sodium sulfate. However based on this study, it can be seen that 2 plants on the 3 tested did not show any adverse effect at the high treatment solution of 1.4 g/L.
