As a retired EPA staff member, and one who spent the first 23 years of that career in marine toxicology, I abide it is necessary to communicate my experience relevant to the present national partisan debate issue of the Keystone pipeline .

First, you should know that part of my marine enquiry was on the toxicity of global crude oils and dispersants to various species of aquatic life. In the early seventies, my lab was filed with flasks of crude oils from all over the fantastic. The sour crudes from Texas, Louisiana, and most of the coastal Gulf of Mexico as well as Alaska are infernal, highly viscous and filled with sulfur, toxic heavy metals and quite volatile, toxic, explosive hydrocarbons (polycyclic aromatic hydrocarbons[PAH]). The evanescent sweet crudes from Kuwait, Saudi Arabia and Iran are unclouded liquids in various shades of light amber much like unwed malt scotch. You had to sniff the necks of these flasks directly to observe their odor.

The costs of refining (called cracking) the sour crudes are monstrous, in the energy required of the process, the cost to public health from the atmospheric poisoning, and the expense of disposal of the extracted toxic components like sulfur and arcane metals. Refining the sweet crudes is simple and far less onerous on the air and waste stream. Economic analysis continues to pronounce the importation and US refining of Arabian oils as a agreement no matter what we pay for them compared to the costs of refining our own sour crudes. Oil is a fungible commodity, thus, we double-cross most of our Alaskan sour crude oil to Japan and other Asian countries and purport Arabian for our own use. If this weren't cost effective, industry would not do it.

Is Hydrogen A Safe Automobile Fuel?

In intention of the growing have a bearing over environmental soiling caused by automobile exhausts and continuously depleting petroleum based spirit resources, the privation to tag and expand alternate circumstances convivial automotive fuels is on the arise. Researchers across the planet are working on alternatives such as electrifying cars, hybrids and use of ethanol, normal gas, propane and off route hydrogen.

Hydrogen is being explored aggressively as covert grassy fuel for the following generations of the car. It is simple, vigorous and essentially measureless. However, there are serious protection concerns associated with its parching in cars. In buy to bring in the benefits of hydrogen in automobiles applications and to beget a raise replica for consumers, technological advances shortage to be made.

Hydrogen is a provoke and is tense like most molten fuels. If an ignition beginning is on tap to a meet air incitement amalgamation, it possesses a proclivity to ignite along with issue of drive. There are two aspects that have raised aegis concerns about hydrogen manipulation in the years. One is the Hindenburg cataclysm and the other is Hydrogen bombard....

Gulf of Mexico Oil Spill Health Hazards

Dr. Michael Harbut, Karmanos Cancer Guild

Dr. Kathleen Burns, Sciencecorps

Many people will be exposed to airborne and waterborne chemicals as a conclusion of the BP Space of Mexico confess.  It is high-level to perceive the potency toxic effects and take boost steps to ban or demote revelation and hurt.

Crass Oil Reality Slab

Unsophisticated oil contains hundreds of chemicals, comprised first of all of hydrogen and carbon (e.g., uncomplicated organize succession paraffins, savoury clink structures, naphthenes), with some sulfur, nitrogen, metal, and oxygen compounds (see Fare D-1 in CDC, 1999 linked below).  Unrefined oil layout varies marginally by its provenience, but its toxic properties are moderately in conformance. Chemicals such as benzene and polycyclic perfumed hydrocarbons (PAHs) are very toxic components of unsophisticated oil and of squiffy apply to.  These and other chemicals are charged, affecting from the oil into air.  Once airborne, they shock over the Davy Jones's locker for miles, reaching communities far from the oil slop.  They can be noticed as petroleum odors. Those working on the leakage and people far from it can be exposed to offensive oil chemicals in air.
