Newly hatched individuals of four estuarine species were exposed to pentachlorophenol (PCP), sodium pentachlorophenate (Na-PCP), or Dowicide G (79%Na-PCP), in static toxicity tests. The 96-hour LC50 values for sheepshead minnow (Cyprinodon variegatus) fry exposed to PCP at ages 1-day, 2-week, 4-week, and 6-week were 329, 392, 240, and 223 micrograms/l, respectively. The 96-hour LC50 value for 2-week-old fry exposed to Dowicide G was 516 micrograms/l. The larvae (48-hour post hatch) of pinfish, Lagodon rhomboides, were particularly sensitive to Na-PCP (96-hour LC50:38 micrograms/l) and Dowicide G(96-hour LC50:66 micrograms/l). For 24-hour-old grass shrimp (Palaemonetes pugio) larvae exposed to NA-PCP the 96-hour LC50 was 649 micrograms/l. NaPCP caused abnormal development of eastern oyster (Crassostrea virginica) embryos, the 48-hour EC50 being 40 micrograms/l.
