چکیده
Following the Deepwater Horizon blowout, oil, degraded oil mixed with dispersants, and management responses to spill affected a variety of Gulf Mexico organisms. This review provides examples various documented impacts, common patterns, trends across organisms and/or their environments, discusses future implications as well directions for research. Organism effects are generally characterized lethal sublethal. Sublethal can be short term, long or permanent multigenerational. We present individual on behavioral response, olfaction, vision, cardiac function, gene shift, based research done in laboratories, mesocosm settings, field. Future should emphasize collection analysis routine toxicological baselines examine how if molecular impacts cascade up populations. will require development rapid tools testing procedures determine exposure compared field-relevant levels able extrapolate laboratory results field, especially given mosaic differing contaminant concentrations (below, at, exceeding critical that result sublethal effects) occurring environment. Recent chemical studies have identified detectable suite polycyclic aromatic hydrocarbon metabolites which there no toxicity data; further is needed food webs.

Impacts of Petroleum-Derived Pollutants on Fish Development.
The teleost fish embryo is particularly sensitive to petroleum hydrocarbons (polycyclic aromatic hydrocarbons, PAHs) at two distinct stages of development. The first is early during cleavage stages when PAHs alter normal signaling associated with establishment of the dorsal-ventral axis. This disruption involves the Wnt/β-catenin pathway and results in hyperdorsalized embryos that do not surviv...
متن کاملEffects of Petroleum on Birds
Oil pollution is in the forefront ofpublic attention because of the recent series of oil spills from tankers such as the Argo Merchant. Oil spillage frequently destroys the marine flora and fauna; the most striking single effect is the oiling of large numbers of marine birds. For example, as many as 30,000 birds died after the grounding of the Torrey Canyon at Seven Stones Reef, Great Britain i...
