Poison bulb

Free-radical copolymerizations have been performed ia bulb (comonomers without solvent), solution (comonomers with solvent), suspension (comonomer droplets suspended ia water), and emulsion (comonomer emulsified ia water). On the other hand, most ionic and coordination copolymerizations have been carried out either ia bulb or solution, because water acts as a poison for many ionic and coordination catalysts. Similarly, few condensation copolymerizations iavolve emulsion or suspension processes. The foUowiag reactions exemplify the various copolymerization mechanisms. 

Fluorides are used in many materials processes, and can poison the environment when they are discarded. Examples are ciyolite (sodium aluminofluo-ride, Na,AlF ) used to dissolve aluminum oxides for electrolysis, and hydrofluoric acid (HE) used in etching lamp bulbs and semi-conducting circuits. Today lamp bulbs are etched much less than they used to be to reduce fluoride disposal not much has been done to reduce the amount of cryolite for aluminum production. 

Never use your mouth instead of a suction bulb to draw a liquid into a pipette. The liquid could be corrosive or poisonous. As well, you would contaminate the glass stem. 

History. For centuries man has recognized that rodent pests destroy his habitat, consume his food, and cause the spread of virulent diseases. Throughout the same centuries man has sought to eliminate these pests with a variety of poisons such as strychnine, arsenious oxide, and red squill - a steroidal glycoside extracted from the bulb of a lily-like plant, Urginea maritima. 

In recent years, there has been considerable stress on the potential health hazards of oral mercury thermometers used for medical purposes. In fact, the risk of mercury poisoning from a broken mercury thermometer in a physical chemistry experiment is extremely low. The key safety rule if such a thermometer were to break is the prompt and efficient cleanup of any spilled mercury see Appendix C for further details. Note that essentially no mercury will be spilled if the stem rather than the bulb is broken. In conclusion, mercury thermometers should be handled with reasonable care, but they are useful and precise scientific instruments of considerable value for research applications. 

In a Turkish case, the ingestion of two bulbs or Urginea maritima as a folk remedy for arthritic pains was sufficient to result in fatal poisoning (27). 

Bulb decoctions of Boophone disticha are used by the Zulu to treat headaches, chest and bladder pains and hysteria. The Sotho and Xhosa use bulbs as a dressing for circumcision and narcotics while the leaves are used for the treatment of skin diseases. Khai and San people use bulbs as arrow poison (43, 44, 45). In Zimbabwe, the bulb is used for constipation, bums, oedema, wounds, rash, dizziness and lucky charms (46). 

In east Africa, C. kirkii is used in Kenya for the treatment of sores. In Tanzania, the frait and iimer parts of the bulb are used as a pmgative and the outer scales are used as a rat poison (50). In Madagascar, the bulb of C. firmifolium is used for the treatment of various parasitic skin diseases (5S). 

Bulbs are cut from the root system with a knife, then dug up. In dry conditions, bulbs can be left in the field to cure. Curing allows the natural dormancy of the poison to develop and also dries out the bulb to protect against disease. A bulb that has been cured correctly will have a dry, shrunken neck and dry outer scales.

Boophane disticha-. The bulb of this amaryllidaceous arrow-poison plant is used as an inebriant in initiatory ceremonies by the Basuto people of South Africa. These bulbs contain 0.31% of a mix of eleven alkaloids of unknown activity, mainly buph-anidrine, undulatine, buphanisine, buphanamine and nerbowdine (De Smet 1996). 

Narciclasine, an alkaloid isolated from the bulbs of narcissus, possesses antimitotic activity against S-180 in ascites form suggesting thereby that it acts essentially as a metaphasic or preprophasic poison. 

The carbon and the sulfur atoms are satished. The compound formed is carbon disulhde, which is a poison by absorption it is a highly flammable, dangerons fire and explosion risk, has a wide flammable range from 1 to 50%, and can be ignited by friction. Carbon disulfide also has a low ignition temperature and can be ignited by a steam pipe or a light bulb. 

In cases in which a relatively large weight of catalyst, compared with that of the poison, is present, e.g., for the adsorption of a gaseous poison, or for an impure gaseous system containing a poison, in an adsorption bulb filled with platinum black, the values for the partition factor Ki may be far greater than those given in the table, which were measured...
