Special Note: Ohio Toxic Plume Represents a Significant Toxicological Threat for Long-Term Adverse Health Effects. The scope, magnitude and duration of the toxic plume produced by ill-advised incineration of chemicals contained in the derailed tank cars is akin to that of a small volcano. The resulting deposition of combustion artifacts released in this plume includes polyarmomatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs), dioxins and other Class 1 carcinogens (cancer-causing agents). These substances can induce both acute and chronic (long-term) adverse health effects in both residents and wildlife. Additionally, the deposition of these substances upon agricultural regions, waterways and public areas may require substantial, costly remediation over wide areas.

Dr. Sawyer Cited in UK Newspaper Regarding Hydrocarbon Contamination of Marine Life

UK Independent News: Hundreds of beached dolphin carcasses, shrimp with no eyes, contaminated fish, ancient corals caked in oil and some seriously unwell people are among the legacies that scientists are still uncovering in the wake of BP's Deepwater Horizon spill. Scientists believe the addition of dispersants to the oil made it more easily absorbed through the gills of fish and into the bloodstream. Dr William Sawyer, a toxicologist, has studied concentrations of petroleum hydrocarbons (PHC) in edible fish and shellfish in the Gulf region. Samples before the spill had no measurable PHC in the tissue, whereas fish tested in recent months show tissue concentrations as high as 10,000 parts per million, or 1 percent of all tissue. Dr. Sawyer stated that: "The study shows that the absorption [of the oil] was enhanced by the Corexit." BP says the dispersants it used are "government approved and safe when used appropriately" and that extensive testing has shown seafood in the Gulf is safe to eat.

Dr. Sawyer Interviewed in "Dead Files" Television Episode

Former NYPD homicide detective Steve DiSchiavi, co-star of "The Dead Files" television series, interviews Dr. Sawyer to gather toxicological information in the hope of finding clues relating to a series of century-old arsenic suicide and murder attempts in Erieville, New York. The case involves a mother who poisoned her husband and three children with a traditional arsenic pesticide compound known as "Paris Green."

Dr. Sawyer Interviewed by Lisa Myers on NBC Nightly News

NBC: Dispersants Increase Impact of Oil on Marine Life: News correspondent Lisa Myers interviews toxicologist Dr. William R. Sawyer in an NBC Nightly News Special Report concerning BP's use of dispersants in the Gulf of Mexico. Evidence suggests that dispersants injected into oil below the surface liberate toxic hydrocarbons which remain suspended and persist in the water, adversely impacting marine life.

Dr. Sawyer Interviewed Concerning Government Interference in Oil Spill Investigation

Scientists Unsettled by Calls From Federal Commission: Some independent scientists who have been looking into oil spill contamination in the Gulf of Mexico said they have received some unsettling phone calls from the federal government. The calls came from attorneys on behalf of the National Oil Spill Commission. The scientists said the questions seemed designed to cast doubts on their findings. Although government officials subsequently claimed that they were merely "reaching out" with the intent of inviting Dr. Sawyer to serve on the Presidential Commission, this was not communicated to Dr Sawyer or to other scientists who received similar calls from attorneys.
