    Effects of heavy metals on development of the killifish, Fundulus heteroclitus (1977)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 11 (1977), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: When F. heteroclitus embryos were exposed to inorganic mercury at concentrations of 0.03 or 0.1 mg/1 at the early blastula stage, the percentage of successful axis formation was reduced and a significant proportion of embryos developed cyclopia or intermediate conditions leading to cyclopia. Treatment at the late blastula stage reduced the severity of the defects. Embryos which developed in lead at concentrations of 1 and 10 mg/1 were normal in appearance until hatching, at which time they exhibited lordosis or were unable to uncurl from the position they had while still inside the chorion. No significant effects of cadmium at concentrations up to 10 mg/1 were noted.

    Effects of mercury on larval and adult grass shrimp (Palaemonetes pugio) (1988)
    Springer
    Archives of environmental contamination and toxicology 17 (1988), S. 355-363

    Notes: Abstract Tolerance to mercury in two populations of the grass shrimpPalaemonetes pugio was examined at different stages of this animal's life cycle. One population came from a mercury-contaminated creek, Piles Creek (PC), near industrialized Linden, New Jersey. The other population came from a relatively clean area, Big Sheepshead Creek (BSC), near non-industrialized Tuckerton, New Jersey. Larval grass shrimp showed no significant difference between populations in terms of mortality in 0.01 mg/L HgCl2, although treated BSC larvae metamorphosed significantly (P 〈 0.05) more slowly than their respective control group. While no BSC larvae survived the 0.0125 mg/L methylmercuric chloride (meHg) treatment, PC larvae exposed to 0.0125 mg/L meHg survived as well as their controls, indicating enhanced tolerance to meHg in this population. Adult shrimp were exposed for 14 days to control, 0.025 mg/L meHg, 0.025 mg/L HgCl2, 0.05 mg/L meHg, or 0.05 mg/L HgCl2 PC shrimp were significantly (P 〈 0.05) more tolerant to both 0.025 mg/L meHg, and 0.025 mg/L HgCl2 than were the BSC adults. Polyacrylamide gel electrophoresis suggests that both populations of shrimp are capable of producing a metallothionein like protein (MT) in response to treatment with HgCl2; MT is found in higher levels in field-caught PC shrimp than in field-caught BSC shrimp. MT was not present in field-collected, viable eggs from either population.

    Toxicity to estuarine organisms of leachates from chromated copper arsenate treated wood (1991)
    Springer
    Archives of environmental contamination and toxicology 20 (1991), S. 118-124 
    Details
    ISSN: 1432-0703

    Notes: Abstract The effects of chromated copper arsenate (CCA), used for treating wood in docks, pilings, and bulkheads, were studied in several estuarine organisms. Leaching of metals from treated wood into sea water was assayed by atomic absorption spectrophotometry. Fiddler crabs (Uca pugilator) were subjected to limb removal and were placed in containers with treated wood of various sizes or control wood. Limb regeneration rate was retarded in a dose-dependent fashion and mortality occurred with the treated wood, reaching 100% in the tank with the largest piece of wood. Embryos of the mummichog (Fundulus heteroclitus) were allowed to develop in culture dishes in which CCA-treated or untreated wood was soaking. Mortality was noted in the dishes with treated wood and to a smaller extent in those with untreated wood. Containers containing CCA-treated wood, control wood, or no wood were stocked first with the algaUlva lactuca, then snails (Nassarius obsoletus). Chlorophyll content of the algae was reduced with the treated wood within a few days, and snails with the treated wood became moribund and died within a few days. In the controls containing untreated wood or no wood, no such effects were seen. Studies with individual or combinations of two or three of the metals with snails and algae indicated that the copper was primarily responsible for the snail mortality and algal bleaching seen in the treated wood experiments. In all experiments, the toxicity of the wood decreased over time; when the experiments were repeated with the same pieces of wood, effects were diminished.

    Toxicity of construction materials in the marine environment: A comparison of chromated-copper-arsenate-treated wood and recycled plastic (1992)

    Notes: Abstract Previous studies have demonstrated leaching from chromated-copper-arsenate (CCA)-treated wood, which is used in pilings and bulkheads, and resulting toxicity to various estuarine organisms. The current study compared effects of leachates from CCA-treated wood with those of recycled plastic “lumber,” a possible alternative construction material. Limb regeneration in fiddler crabs, while depressed in leachates from CCA wood, was accelerated in three formulations of recycled plastics. The acceleration was reduced in subsequent trials with the same pieces of plastic. Using a sea urchin fertilization test, no effects were seen in 1- and 3-day leachates from the plastics. However, CCA wood reduced fertilization by 90%, and totally inhibited larval development of those that did fertilize. A smaller piece of wood, one-tenth the size (0.4 cm2), did not have a significant effect on fertilization or development. With 1–3 weeks of leaching, significant reductions in fertilization were seen in sea urchin gametes exposed to one plastic formulation and no fertilization was seen in leachates from the small piece of CCA wood. Two formulations enriched to 30% polystyrene (PS) had no significant effect on fertilization, but did reduce larval growth. When the same pieces of plastic and wood were used for a second set of experiments, all three formulations of plastic, as well as the small piece of wood, inhibited fertilization significantly, and one of the 30% PS formulations and the wood caused reduced larval growth. In another assay, snails and an alga were exposed to plastics for two months with no observed effect; the CCA leachates caused 100% snail mortality within one week and chlorosis of the alga. Chemical analysis by GC/MS revealed a large number of chemicals leached in various quantities from the plastic.
