request for information on dermal or oral toxicity

[Shelley Cole]

I have the need to evaluate the following compounds for their dermal and 
oral toxicity:

1. Co2(PO4)3 - cobalt phoshate - Co(III) This is unhydrated and a red to 
purple colored crystalline powder

2. CoO - cobalt monoxide - Co(II) black/grey powder

3. Co2O3 - cobalt trioxide - Co(III) also I believe a black/grey powder

These substances are formed as the result of the burning of jet fuel and 
deposited within the jet engine.
