Concentration of lithium after acute exposure. A Plasma, B CSF and C CSF/plasma ratios (%) of animals following a single i.p. dose of lithium (3.2 mg/kg body weight). Means ± SD when n > 2. Blue points are samples measured using ICP-MS and black points are samples measured using LA-ICP-MS, each point is an individual animal. #Significantly different from all other groups. Ages in brackets refer to age when fetuses/pups were sampled
