He said more research was urgently needed to answer several questions, including why the level of contamination offshore near the plant was so high.
In recent years, a group of progressives won election to the city council and the mayor's seat, despite huge expenditures by Chevron, the corporation that also brought you gigantic oil spills onshore in Ecuador and offshore in Brazil, massive contamination from half a century of oil extraction in Nigeria, and Canadian tar-sands bitumen sent by rail to the Richmond refinery.
Developing a baseline estimate of diversity is absolutely imperative, particularly in light of the future potential anthropogenic impacts in the deep-sea Gulf of Maine region: offshore waste disposal, chemical contamination, expanding oil and gas exploration, alien species, increased ship traffic, fishing to progressively deeper waters, and climate change [2], [85].
And all of this takes place offshore, relieving concerns about water contamination and subsidence, he argues.
Locals have estimated that the only area still affected by contamination is just offshore from the Alcoa plant.
Phenols compounds have been identified in marine phanerogames [ 39- 41] and high concentrations of phenolic compounds in Posidonia leaves were found in a few cases a) under competition with Caulerpa taxifolia [ 42, 43], b) under mercury contamination [ 44], c) nearby offshore aquaculture cages [ 45].
Spat were deployed on oysters beds in April 2011 at three distinct sites, an oyster production area where mortalities on spat was observed in Spring (BL, Blainville sur mer, West Coast of Normandy) whereas to others sanctuary sites (CRIC, Cricqueville en Bessin, East coast of Normandy without oyster production and in an offshore 100m capacity storage structure deprived from contamination, CAB).
Petroleum contamination is linked to accidents during oil extraction and transportation, oil tankers, and offshore oil.
Communities along Spain's northern coast girded for widespread oil contamination in the coming days after a crippled tanker holding twice the load lost aboard the Exxon Valdez split in two today and sank more than 100 miles offshore.
