I came across a paper on the exposure of zebrafish to BPA at realistic environmental concentrations and I found no mention of any solvent used to dissolve the BPA. Instead, the exposure was carried out directly in water. Considering my experience with BPA, it’s commonly dissolved in DMSO or ethanol and isn’t easily soluble in water except at very low concentrations. Is there any literature demonstrating BPA exposure without the use of solvents?
