Like salad dressing: toxic effects to fishery and wildlife, surface coating gill fouling, hypothermia, negative buoyancy. If fish gills are taken up by oil, they can"t breath, asphyxiate i: this doesn"t affect fish as much because they can swim away, and have good sense of smell ii. Carcinogenic/mutagenic: relative sensitivities of petroleum, pelagic community i. fish, subtidal benthic community c. Oil impacts are greatest in tidal region because they cannot leave, and are stuck: )ildlife community. A response has benefits, but it also has a cost (cid:840)1696(cid:841) Doing nothing has benefits, but it also has a cost iii. Not a quick solution; good to use to get rid of oil over months i. Becomes dissolved: )e do this all the time with dish soap, laundry, shampoo i. Became unstable and collapsed and sank into the ocean; oil spewing out of the broken casing.
