Lead poisoning in the context of "Gunshot wound"

Gasoline (North American English) or petrol (Commonwealth English) is a petrochemical product characterized as a transparent, yellowish and flammable liquid normally used as a fuel for spark-ignited internal combustion engines. When formulated as a fuel for engines, gasoline is chemically composed of organic compounds derived from the fractional distillation of petroleum and later chemically enhanced with gasoline additives. It is a high-volume profitable product produced in crude oil refineries.

The ability of a particular gasoline blend to resist premature ignition (which causes knocking and reduces efficiency in reciprocating engines) is measured by its octane rating. Tetraethyl lead was once widely used to increase the octane rating but is not used in modern automotive gasoline due to the health hazard. Aviation, off-road motor vehicles, and racing car engines still use leaded gasolines. Other substances are frequently added to gasoline to improve chemical stability and performance characteristics, control corrosion, and provide fuel system cleaning. Gasoline may contain oxygen-containing chemicals such as ethanol, MTBE, or ETBE to improve combustion.

Pewter (/ˈpjuːtər/) is a malleable metal alloy consisting of tin (85–99%), antimony (approximately 5–10%), copper (2%), bismuth, and sometimes silver. In the past, it was an alloy of tin and as much as 40% lead, but most modern pewter, in order to prevent lead poisoning, is not made with lead. Pewter has a low melting point, around 170–230 °C (338–446 °F), depending on the exact mixture of metals. The word pewter is possibly a variation of "spelter", a term for zinc alloys (originally a colloquial name for zinc).

White lead is the basic lead carbonate 2PbCO₃·Pb(OH)₂. It is a complex salt, containing both carbonate and hydroxide ions. White lead occurs naturally as a mineral, in which context it is known as hydrocerussite, a hydrate of cerussite. It was formerly used as an ingredient for lead paint and a cosmetic called Venetian ceruse, because of its opacity and the satiny smooth mixture it made with dryable oils. However, it tended to cause lead poisoning, and its use has been banned in most countries.

Basic lead carbonate is produced by treating lead acetate with carbon dioxide and air. In the laboratory procedure treats lead acetate with urea. It occurs naturally as the mineral cerussite. The compound has been characterized by X-ray crystallography, which confirms the formula. The structure is complicated, features two kinds of Pb(II) sites, those bonded to hydroxide and those bonded to carbonate and hydroxide.

Kohl is a cosmetic product traditionally made by crushing stibnite (antimony sulfide). Modern kohl formulations often contain galena (lead sulfide), and in some cases charcoal or other pigments. Kohl is similar to eyeliner, which was traditionally made from charcoal. Kohl is widely used in many cultures to contour or darken the eyelids and heighten beauty marks. Several studies have questioned the safety of kohl out of fear of lead poisoning. Importing galena kohl into the United States is banned.

Dystonia is a neurological hyperkinetic movement disorder in which sustained or repetitive muscle contractions occur involuntarily, resulting in twisting and repetitive movements or abnormal fixed postures. The movements may resemble a tremor. Dystonia is often intensified or exacerbated by physical activity, and symptoms may progress into adjacent muscles.

The disorder may be hereditary or caused by other factors such as birth-related or other physical trauma, infection, poisoning (e.g., lead poisoning) or reaction to pharmaceutical drugs, particularly neuroleptics, or stress. Treatment must be highly customized to the needs of the individual and may include oral medications, chemodenervation botulinum neurotoxin injections, physical therapy, or other supportive therapies, and surgical procedures such as deep brain stimulation.
