Abstract The toxicity and bioaccumulation of hexachlorocyclopentadiene, hexachloronorbornadiene and heptachloronorbornene to fathead minnow larvae and early juveniles was conducted for 30 days under flow through conditions. The 96-hr LC50 and 30-day LC50 values for these compounds, respectively were: 7.0 and 6.7 microgram/l, 188 and 123 microgram/l, and 85.6 and 60.1 microgram/l. Residues of hexachlorocyclopentadiene in 30-day-old larvae were less than 0.1 microgram/l resulting in a BCF of <11. The concentration of hexachloronorbornadiene and heptachloronorbornene accumulated by fathead minnows was directly proportional to the mean exposure concentration up to an effect concentration of approximately 40 microgram/l and resulted in BCFs of 6,400 and 11,200 for each compound, respectively.
