Additional information

Male and female Poecilia reticulata were exposed to sodium bromide in a semi-static toxicity to reproduction test. Observations of mortality, abnormal behaviour and reproductive effects along with histopathological studies were used to determine the NOEC value. Histopathological changes were noted at concentrations of 78 mg Br-/L and above. The lowest NOEC for the sodium bromide for reproductive effects in fish is 10 mg/L from the study by Canton et al., 1983. An additional study (Wester P.W.et al., 1988;) also found the NOEC based on histopathological changes to be 10 mg/L but the study did not evaluate the reproductive effects of the test substance. Organs affected included the thyroid, gonads, skeletal muscle and mesenteric arteries.
