Key value for chemical safety assessment

Additional information

SFL is primarily composed of inorganic substances (the major constituent is calcium carbonate, along with silicon dioxide and a small amount of other inorganic salts) and the remainder is composed of organic plant material. SFL is not classified as harmful or toxic to the environment. The inorganic portion of SFL and the organic plant material are composed of substances which are naturally occurring in the environment. Hence, aquatic organisms including fish are constantly exposed to the components of SFL without suffering from any adverse or detrimental effects.

An acute toxicity study to Oncorhynchus mykiss (rainbow trout) was performed according to OECD 203 with a saturated solution (100% v/v) of calcium carbonate (nano) [Priestly (2010a)]. No mortalities or sub-lethal effects were observed in any of the fish exposed. As a result, calcium carbonate is considered not acutely toxic to fish. This result is considered to be relevant to SFL based on the fact that SFL is primarily composed of calcium carbonate and other calcium salts and hence the properties of SFL are governed by those of calcium carbonate. It can therefore be assumed that SFL is not acutely toxic to fish and hence long term testing is considered to be unnecessary.
