Heavy-petroleum fuels raising vanadium emission

Heavy-petroleum fuels raising vanadium emissions
Human emissions of potentially harmful vanadium particles into Earth's atmosphere now exceed those from all natural sources combined.

Summary: Human emissions of the potentially harmful trace metal vanadium into Earth's atmosphere have spiked sharply since the start of the 21st century due in large part to industry's growing use of heavy oils, tar sands, bitumen and petroleum coke for energy, a new Duke study finds. These emissions now exceed those from all natural sources combined. Growing evidence suggests exposure to vanadium-rich aerosols can impair respiratory functions and exacerbate conditions such as asthma or COPD.

Human emissions of the potentially harmful trace metal vanadium into Earth's atmosphere have spiked sharply since the start of the 21st century due in large part to industry's growing use of heavy oils, tar sands, bitumen and petroleum coke for energy, a new Duke University study finds.

"Human emissions of vanadium to the atmosphere now exceed those from all natural sources combined -- by a factor of 1.7," said William H. Schlesinger, James B. Duke Professor Emeritus of Biogeochemistry at Duke's Nicholas School of the Environment, who led the study.

"Less than two decades ago, the ratio of human to natural emissions was 0.59 to 1, or less than half the current level," Schlesinger said. "Our analysis suggests that much of this rapid rise can be traced to the increased use of unconventional heavy-petroleum fuels."

Vanadium is a trace metal found in many earth materials, including petroleum and coal. It is emitted as particulate matter when these materials are burned, and can also be released as accidental, or "fugitive," emissions during mining, extraction and processing.

Natural sources of vanadium emissions include volcanic eruptions and the weathering of rocks.

The health risks of exposure to airborne vanadium particles are not as well documented as those for other metallic airborne contaminants such as mercury or lead, but growing evidence suggests breathing vanadium-rich aerosols can impair respiratory functions and exacerbate conditions such as asthma and chronic obstructive pulmonary disease (COPD).

I say we declare war against Vanada immediately, invade their backass country, and put and end to ...wait, what?

You need boats to get there, and they have 547 police, some of whom may be armed. This is not a cakewalk.
