Toxicity of creosote to larval and adult lobsters and Crangon and its accumulation in lobster hepatopancreas

Fluorescence spectroscopy was used to show that larval lobsters are more sensitive to creosote than adults, the 96-hour thresholds differing by about two orders of magnitude. The larvae and Crangon septemspinosa have similar sensitivity except at the lowest concentrations tested (0.3 mg per litre),...

Description
Summary:Fluorescence spectroscopy was used to show that larval lobsters are more sensitive to creosote than adults, the 96-hour thresholds differing by about two orders of magnitude. The larvae and Crangon septemspinosa have similar sensitivity except at the lowest concentrations tested (0.3 mg per litre), so that the 96-hour threshold is lower for lobster larvae than that for Crangon. The data for 0.3 mg per litre exposure suggest that the concentration of creosote in the hepatopancreas of adult lobsters continues to rise with time, up to 120 hours at least, at a rate of about 85 ug per g lipid. hour. Lobsters that died had concentrations of 47,500 and 23,700 ug per g lipid in the hepatopancreas; those with 10,850 ug per g lipid or less were apparently healthy when sampled.
