Sodium formate

Bioaccumulation: aquatic / sediment

Link to relevant study record(s)

Reference

Reference 1

Endpoint:

bioaccumulation in aquatic species, other

Type of information:

(Q)SAR

Remarks:

Estimated by calculation

Adequacy of study:

other information

Reliability:

4 (not assignable)

Rationale for reliability incl. deficiencies:

other: Generally scientifically accepted method, but EPI Suite not validated for inorganic salts

Principles of method if other than guideline:

Calculated Bcfwin (v2.15)

Type:

BCF

Value:

3.16 L/kg

Remarks on result:

other: Bcfwin (v2.15) QSAR calculation based on formic acid log Kow of -0.54.

BCF estimation:

Metals (Na) are removed for BCF estimation.

- log Kow used: -0.54 (from formic acid)
- equation used: log BCF = 0.5 (ionic; log Kow dependent)

Validity criteria fulfilled:

not applicable

Conclusions:

A BCF value of 3.16 L/Kg was estimated for sodium formate by the Bcfwin (v2.15) QSAR in the EPISuite (v3.12) software using a Log Kow value of -0.54 (from formic acid).

Executive summary:

A BCF value of 3.16 L/Kg was estimated for sodium formate by the Bcfwin (v2.15) QSAR in the EPISuite (v3.12) software using a Log Kow value of -0.54 (from formic acid). However, this BCF value is not assignable since EPISuite is not validated for inorganic salts.

Endpoint:

bioaccumulation in aquatic species: fish

Data waiving:

study scientifically not necessary / other information available

Justification for data waiving:

the study does not need to be conducted because the substance has a low potential for bioaccumulation based on log Kow <=3

Justification for type of information:

In accordance with column 2 of REACH Annex IX, the study does not need to be conducted if the octanol/water partition coefficient is <3. Due to the low log Pow of <-1.8 (Perstorp, 2009), accumulation in organisms is not expected. Thus, and for reasons of animal welfare, no study on bioaccumulation in fish is performed.

Reason / purpose for cross-reference:

data waiving: supporting information

Description of key information

Significant bioaccumulation in organisms is not expected.

In accordance with column 2 of Annex IX, a bioaccumulation study does not need to be conducted if the octanol/water partition coefficient of the substance is <3. Due to the low log Pow of <-1.8 (Perstorp, 2009), accumulation of sodium formate in organisms is not expected. Thus, and for reasons of animal welfare, no study on bioaccumulation in fish is performed.
