The Utes or Utahs are a North American tribe of Indians, a chief branch of the Shoshone division. They were traditionally hunters, skilled with the horse. They were once scattered over Colorado, New Mexico, California, Nevada and Utah by 1900 they had dwindled to 2500 distributed in Nevada, Colorado and Utah.
They were generally friendly to the whites, but following the invasion of their lands in Utah, Utah bands carried on hostilities with the Mormon invaders. Subsequently disturbances occurred between them and invading miners at Pike's Peak and they defeated Major Ormsby on the Truckee River. In 1865 large tracts of land were ceded to the United States. Later trouble arose with Black Hawk, a chief of the Pah Utes, and for several years bloody warfare followed. Research Utes
Benzo[a]pyrene (B[a]P) is one of the polycyclic aromatic hydrocarbon (PAH) compounds. Because it is formed when petrol, rubbish, or any animal or plant material is burned, it is usually found in smoke and soot. Benzo[ a]pyrene is also found in the coaltar pitch that is used to join electrical parts together and in creosote. Research Benzo[a]pyrene
Polycyclic aromatic hydrocarbons (PAHs) are a group of chemicals that are formed during the incomplete burning of coal, oil and gas, garbage, or other organic substances. PAHs can be man-made or occur naturally. There is no known use for most of these chemicals except for research purposes. A few of the PAHs are used in medicines and to make dyes, plastics, and pesticides. They are found throughout the environment in the air, water, and soil. There are more than 100 different PAH compounds. Although the health effects of the individual PAHs are not exactly alike, the following 15 PAHs are considered as a group: acenaphthene, acenaphthylene, anthracene, benz(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(ghi)perylene, benzo(k)fluoranthene, chrysene, dibenz(a,h)anthracene, fluoranthene, fluorene, indeno(1,2, 3-cd)pyrene, phenanthrene, pyrene. As pure chemicals, PAHs generally exist as colourless, white, or pale yellow-green solids.
Most PAHs do not occur alone in the environment (including those found at hazardous waste sites), rather they are found as mixtures of two or more PAHs. They can occur in the air either attached to dust particles, or in soil or sediment as solids. They can also be found in substances such as crude oil, coal, coaltar pitch, creosote, and road and roofing tar. Most PAHs do not dissolve easily in water, but some PAHs readily evaporate into the air. PAHs generally do not burn easily and they will last in the environment for months to years.

The Messerschmitt-Bolkow-Blohm PAH-1 (BO 105P) is the German army two-seater anti-tank helicopter variant of the BO 105 series. It is armed with the provision for one Rheinmetall HBS 202 fixed under-fuselage 20 mm cannon system, or for one side-mounted Emerson Flexible Turret System with a 7.62 mm General Electric GAU-2/A Minigun and up to 1000 kg of disposable stores carried on two hard points, one on each side of the fuselage on outriggers, typically comprising six Euromissile HOT anti-tank missiles or eight Hughes BGM-71 TOW ant-tank missiles.
