Independent Toxicologists Issue Warning: We Object to the Claim That Chemical Dispersants Have A Low Potential For Accumulating in Marine Life and Do Not Pose an Environmental Health Concern

/PRNewswire/ -- Attorney Stuart H. Smith, representing the United Commercial Fishermen's Association, the Louisiana Environmental Action Network, public and private entities, and citizens harmed by the BP oil catastrophe, today issued this statement:

"Independent analysis by toxicologists dispute FDA claims made in the last few days that chemical dispersants used by BP during the oil catastrophe may not accumulate in marine animals.

"In fact, in a full report by Dr. Bill Sawyer released today, there is a grave problem caused by dispersants, due to the fact that these were used in deep waters and on such a vast scale.

"Studies of other spills show that the toxic components of crude oil 'bio-accumulate' into the food chain and become highly toxic to marine reproduction, even when dispersants are applied at the surface and the chemical toxins may be sufficiently diluted over time to pose only minimal risks.

"However, BP's use of dispersants deep underwater in the Gulf, and on such a vast scale, represents the first time dispersants have been used in this manner. The greatly-reduced biodegradation in the DEEPWATER HORIZON case, resulting from lack of sunlight, extreme cold temperatures at 5,000 feet, and other environmental factors significantly reduce the rate at which the dispersed crude components are degraded.

"Eight months would be required to remove 96 percent of the petroleum under ideal conditions, thus we can only assume what remains in the Gulf waters will be a 'toxic soup' of chemicals for the foreseeable future, due to the worst-case scenario which has unfolded.

"The most potentially dangerous of the components in the Gulf's toxic soup are 'polynuclear aromatic hydrocarbons' (PAHs), dangerous cancer-causing chemicals which slowly break down after being ingested by marine life, persist in marine organisms and can be passed to both humans and other wildlife through consumption.

"PAHs are not contained within the dispersants used, but rather, have been extracted from the BP crude and suspended in the water column via dispersant use.

"It must also be noted that the deep water National Oceanic and Atmospheric Administration Weatherbird analyses and our own near shore water, tunicate and beach samples have revealed a consistent pattern of dispersant-induced C19-C36 hydrocarbons and PAHs. Unfortunately, these specific PAHs are of the most toxic variety."

Healthy Oceans Can Help Save Us From Climate Change

/PRNewswire/ -- A large international coalition today urged the United States to support marine conservation options that will help mitigate climate change.

The 'Blue Climate Coalition,' comprised of sixty-six conservation groups and interests and over 150 marine scientists and professionals, from 33 countries, issued communications today addressed to President Obama and the United States Senate.

Together, the coalition letters request the option for marine conservation solutions to climate change to be considered in national climate change legislation and international climate change treaties, and support for marine science research that further explores this concept.

Eminent oceanographer and conservationist, Dr. Sylvia Earle, endorsed the letters as the first scientist to sign-on. In her latest book, 'The World Is Blue,' Earle reveals how dangerous oceanic change threatens the very existence of life on Earth and argues for renewable strategies that safeguard the natural systems that sustain us.

News of the coalition's effort made its way to Hollywood, and to the notice of Gilles Marini, most recently of 'Sex and the City' and 'Dancing With the Stars.' Gilles signed the letters as a supporter of healthy oceans.

Philippe, Jr., and Alexandra Cousteau, grandchildren of Jacques-Yves Cousteau, signed-on, representing their respective conservation organizations EchoEarth International and Blue Legacy International.

A wide range of interests were represented in the coalition letters: environmental conservation, climate change education and advocacy, ecosystem restoration, the dive industry, ecotourism and sustainable travel, carbon offsetting, fishing, and scientific research.

Scientific Backing

The coalition's message is supported by reports released recently by the United Nations Environment Programme (UNEP) and the International Union for Conservation of Nature (IUCN). UNEP's 'Blue Carbon' report highlights the carbon storage potential of coastal and marine ecosystems, such as mangrove forests, seagrass meadows, and saltwater marsh lands.

The UNEP report found that the restoration of coastal and marine ecosystems and a reduction in the clearcutting of tropical forests could mitigate anthropogenic carbon emissions by up to 25%.

The IUCN report, titled 'The Ocean and Climate Change,' finds that failure to recognize the ocean in climate change discussions will have profound consequences for humanity. The report also recommends for additional research to quantify the carbon value of ocean ecosystems. This recommendation is echoed in the coalition letters, to ensure full scientific backing any future natural ocean carbon policies.

"Utilizing the natural carbon functions of both the green and blue biospheres of our planet is an option that we simply cannot afford to ignore if we are serious about tackling climate change and making the transition to a sustainable low-carbon economy," said Mark J. Spalding, President of The Ocean Foundation and signatory to the coalition letters.

The Urgency of Action

"The United States will play a crucial role in next month's climate change discussions in Copenhagen," said Steven J. Lutz, Executive Director of Blue Climate Solutions, the group that organized the letters. "We are asking the United States to show global leadership by advancing solutions for climate change that involve coastal and marine conservation. Many U.S. federal and state agencies are already pursuing actions that could be considered climate mitigation, such as the restoration of coastal and estuarine habitats. These actions need to be continued and encouraged."

Recognizing the carbon value of healthy coastal and marine ecosystems may be significant for achieving consensus at the Copenhagen negotiations. The health of coastal ocean ecosystems is a critical issue for many developing countries, especially small island developing states. The need to restore the ocean's natural carbon function could help direct billions of dollars towards conservation efforts, while simultaneously supporting local economies and countering the threat of climate change throughout the globe.

Economic stimulus associated with restoring the ocean's natural carbon function include funding and investment for activities such as improving water quality, ecosystem restoration, coastal surveying, and the innovation of new environmental monitoring and restoration technologies.

"Restoring the ocean's natural ocean carbon function is proposed as an alternative to potentially harmful ocean geo-engineering schemes recently discussed in Congress," said Lutz. "Restoration activities that naturally fix carbon in to forms other than dissolved carbon will also not increase ocean acidification."

Environmental co-benefits associated with natural ocean carbon solutions include renewed and sustainable fisheries, the conservation of endangered marine species and birds, and the restoration of certain coastal ecosystems. Mangrove forests are considered essential habitat for many fish species, and healthy seagrass meadows are indispensable for endangered sea turtles and manatees.

"Sea turtle hatchlings need healthy coastal and marine ecosystems in order to survive," said Lutz. "It just so happens that we also need the same healthy ocean ecosystems to survive on this blue planet."
