Additional information

Toxicity to soil macroorganisms except arthropods:

Since

a) Calcium iodate is readily biodegradable

b) It is not applied directly to soil and

c) the substance is not expected to be transferred indirectly to soil in significant quantity via disposal of STP sludges or aerial deposition

d) Also the exposure of soil macroorganisms to calcium iodate is unlikely to occur.

Consequently tests of the toxicity of calcium iodate to soil macroorganisms are considered to be unnecessary.

Toxicity to terrestrial arthropods:

In accordance with column 2 of Annex IX, toxicity on terrestrial arthropods need not be conducted if direct or indirect exposure of the soil compartment is unlikely. None of the uses of calcium iodate involve application to soil and hence this testing was considered to be waived.

Toxicity to terrestrial plants:

Since

a) Calcium iodate is readily biodegradable

b) It is not applied directly to soil and

c) the substance is not expected to be transferred indirectly to soil in significant quantity via disposal of STP sludges or aerial deposition

d) Also the exposure of terrestrial plants to calcium iodate is unlikely to occur.

Consequently tests of the toxicity of calcium iodate to terrestrial plants are considered to be unnecessary.

Toxicity to soil microorganisms:

Since

a) Calcium iodate is readily biodegradable

b) It is not applied directly to soil and

c) the substance is not expected to be transferred indirectly to soil in significant quantity via disposal of STP sludges or aerial deposition

d) Also the exposure of soil microorganisms to calcium iodate is unlikely to occur.

Consequently tests of the toxicity of calcium iodate to soil microorganisms are considered to be unnecessary.
