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
Incendiary balloon strung below. The prevailing wind blowing in from the Mediterranean Sea, propels the balloons inland from Gaza into Israel. As of 10 July 2018, incendiary kites and balloons started 678 fires in Israel, burning of woodland, of agricultural crops, as well as open fields.
