Naphthenic acid agents, thickening agent of napalm and oil drying agents used in painting and wood surface treatment. Industrially useful naphthenates include those of aluminium, magnesium, calcium, barium, cobalt, copper, lead, manganese, nickel, vanadium, and zinc. One oft-cited study stated that "naphthenic acids are the most significant environmental contaminants resulting from petroleum extraction from oil sands deposits." However "under worst-case exposure conditions, acute toxicity is unlikely in wild mammals exposed to naphthenic acids in AOS tailings pond water, but repeated exposure may have adverse health effects." Naphthenic acids are present in Athabasca oil sands (AOL) tailings pond water (TPW) at an estimated
Ucuhuba seed oil Ucuhuba seed oil Ucuhuba seed oil is the oil extracted from the seed of "Virola surinamensis" (ucuhuba). The ucuhuba tree is found in Brazil, Costa Rica, Ecuador, French Guiana, Guyana, Panama, Peru, Suriname, and Venezuela. Its seeds provide oil rich in myristic acid. The ucuhuba oil contains 13% lauric acid, 69% myristic acid, 7% palmitic acid and traces of oleic acid and linoleic acid. Myristic and lauric acids comprised 91.3 mole % of the total fatty acids. Although additional saturated fatty acids were found (decanoic acid, palmitic acid, and stearic acid), they occurred only as minor components. Small amounts of
