---

lead1 acetate

sugar of lead, formed on lead paint surfaces after much weathering; it is palatable and attracts animals to lick the surface, causing lead poisoning.

lead1 acetate paper strips

detect hydrogen sulfide gas formation and used as a test for Brucella spp.

lead1 arsenate

used as an insecticidal and fungistatic spray in orchards; capable of causing arsenic poisoning.

lead1 carbonate

white lead used in paints.

lead1 chromate

used in paints as a hardener and coloring agent.

lead1 equivalent

measurement of the protective efficiency of clothing and other materials against x-rays, in terms based on comparison with lead sheeting of specific thickness.

lead1 letters

used as markers on x-ray films.

lead1 poisoning

a form of poisoning caused by the presence of lead or lead salts in the body. Lead poisoning affects the brain, nervous system, blood and digestive system. It can be either chronic or acute. This is a common finding in cattle and in urban dogs because of the frequent presence of lead in the environment in lead paints, and the sweet taste of the paint when it is weathered.

Adult animals show a subacute syndrome of severe depression, aimless walking, blindness, complete ruminal stasis and a black diarrhea in small amounts. Calves show violent convulsions and death within a few hours.

Poisoning can result from swallowing paint flakes or chewing surfaces covered with lead-based paints, golf balls, newsprint, linoleum, fishing sinkers, or numerous other household objects containing lead. Clinical signs usually include abdominal pain, vomiting, diarrhea and seizures. Basophilic stippling of red blood cells, nucleated red blood cells, and a moderate anemia are characteristic.

lead1 protective clothing

aprons and gloves containing lead and worn as protection against scattered x-irradiation.

red lead1

tri-plumbic tetroxide.

lead1 shot

see lead poisoning (above).

lead1 sulfide

form of lead found in the ore galena.

lead1 weights

made of metallic lead, used in window sashes, can cause poisoning.
