Acute and chronic bioassays were used to evaluate the lethal and sublethal effects of copper chloride and tributyltin chloride on mahi mahi (Coryphaena hippurus) embryos, a pelagic life stage often found in the surface microlayer where anthropogenic contaminants can accumulate. Acute bioassay testing determined the median lethal concentration (LC50) for the test organism after 48 h of exposure. Chronic toxicity tests were used to determine the measurement of sublethal parameters, such as developmental abnormalities after 72-h exposures to the toxicants. Embryos were collected 4 h postfertilization and subsequently exposed to 1, 5, 25, 50, and 100 microg/L of copper chloride and 3, 10, 20, 30, and 50 microg/L of tributyltin chloride. Analysis of hatch rate percentage determined that the mean 48-h LC50 of copper chloride and tributyltin chloride was 32.8 and 16.7 microg/L, respectively, based on the pooled data of four experiments with four replicates for each metal. Consistent abnormalities, such as yolk sac swelling, spinal deformities, and decreased hatch rates, were observed for each metal. Teratogenic responses to copper chloride and tributyltin chloride demonstrate the need to investigate further the impacts of pollution in the open oceans to a species indigenous to, and commercially important to, the Florida (USA) coasts. This information could then lead to the future development of a surface microlayer bioassay using mahi mahi embryos.

“…As both autotrophic and heterotrophic organisms, corals may accumulate insecticides directly across membranes, as well as through feeding upon contaminated zooplankton, suspended particulate matter and sediment particles. The sea-surface microlayer (upper 50 µm) is also a concentration point for a range of anthropogenic contaminants, including pesticides, which can be found at concentrations 100s of times higher than in the water column (Hardy et al 1987). Coral eggs are highly buoyant, and therefore fertilisation may suffer from unrecognised pesticide accumulation on the ocean surface.…”

“…SML enrichment may be explained by considering the hydrophobic character of POPs and their great affinity with surfactants collected at the air-water interface (García-Flor et al, 2005) and it may be well represented by the enrichment factor EF, calculated as the ratio between SML and SSW concentrations (Hardy et al, 1987). For P PCBs in the ÔdissolvedÕ phase it varies from 0.7 to 1.5 at station 1 and from 0.8 to 2.0 at station 2, while in the ÔparticulateÕ phase the enrichment is plainly evident and EF ranges from 2.0 to 10.1 at station 1 and from 0.7 to Fig.…”

Polychlorinated biphenyls (PCBs) and polycyclic aromatic hydrocarbons (PAHs) are two classes of micropollutants intensively monitored and regulated due to their toxicity, persistency and wide diffusion. Their concentrations have been investigated in sea-microlayer (SML) and sub-surface water (SSW) samples collected at two sites of the Venice Lagoon, a fragile ecosystem highly influenced by industrial and anthropogenic emissions. The total P PCB concentration varies from 0.45 ng/l to 2
