The inipol that was the French Inipol was 'revamped' by Exxon... adding 22 additional chemicals... the 4 above should be the dangerous ones, but who knows?

Inipol originated in about 1985 per EPA info.  Exxon took an old formula & revamped it, creating in about 7/28/89 Inipol EAP22 It was experimental * pg bottom . . . not sure who was checking as the "experiment" proceeded.  Each govt entity says it was someone else.  Exxon did have a rep with each little team of workers... they did take urinalysis daily of workers & drew blood of some workers, as well.   *  Results were not given to State Health Dept nor to the workers themselves.  NIOSH knows nothing about it; EPA says others were taking care of it... Labor Dept says they didn't.  Maybe no one did.  At least Exxon knows what this chemical did to humans... at that time.  Since long term health monitoring is required by law when working with a toxic 6.1 chemical such as 2-butoxyethanol, Exxon should also still know what the long term health consequences are on humans. (Had they done the health monitoring they should have, they would know.) These hundreds of men  NEED to know, or the experiment continues ... sadly, doctors will try this & that & not know what they are really dealing with.


Other comments"Soil Microbes and Bioremediation"

"Inipol (an “oleophilic” fertilizer) is a stable water-in-oil formulation that yields an N-P-K ratio of 7.3:0.8:0. The nitrogen source is urea and the phosphorus source is trilaureth (4)-phosphate."

"At room temperature, Inipol has the consistency and appearance of honey, and it must be heated to 90oC (194oF) before it can be sprayed on the soil.  * Inipol was applied as a thin coat to the shore at a rate of 306 ml m-2 (0.27 quart per square yard). As the microemulsion mixed with the weathered crude oil, the crude oil destabilized Inipol to release its urea-N. "

"In addition, a surface-active organic material (oleic acid) in Inipol served as a readily degradable carbon and energy source to increase the activity and number of indigenous hydrocarbon-degrading bacteria. When the oleic acid was depleted, the increased biomass of hydrocarbon-degrading bacteria supported enhanced biodegradation of the petroleum."

". . . passive bioremediation also undoubtedly occurred in the absence of the fertilizer nitrogen and phosphorus . . ."
