Toxicants PELs, table

Exposure to metal carbonyls can present a serious health threat. Nickel carbonyl is considered to be one of the most poisonous inorganic compounds. However, the toxicological information available on metal carbonyls is restricted to the mote common, commercially important compounds such as Ni(CO)4 and Ee(CO). Other metal carbonyls are considered potentially dangerous, especially ia the gaseous state, by analogy to nickel and iron carbonyls. Data concerning toxicological studies on a few common metal carbonyls are Hsted ia Table 6 (185). Additional toxicity data are OSHA personal exposure limits (PEL) for Ee(CO) this is 8 h at 0.1 ppm, whereas for the much more toxic Ni(CO)4 it is 8 h at 0.001 ppm, with a toxic concentration TCLq low (of 7 mg/m ) for human inhalation. 

TLV and PEL values for a variety of toxicants are provided in Table 2-8. Table 2-8 TLVs and PELs for a Variety of Chemical Substances ... 

The PELs and RfDs in this table may not be based on the same toxicity endpoints. 

Evaluating the toxicity of solvents provides one metric for comparing potential candidates. This evaluation (usually the LD50 or PEL (permissable exposure level)) allows one to screen out solvents that are environmentally undesirable. In actual practice, the preliminary ranking should incorporate the criteria given in Table V. In general, despite the data available in all the areas listed in Table V, chemists have not... 

The Occupational Safety and Health Administration (OSHA) Toxic and Hazardous Substances (Tables Z.l, Z.2, and Z.3) of air contaminants, found in 29 CFR 1910.1000. These tables record permissible exposure limits (PELs), time-weighted averages (TWAs), and ceiling concentrations for the materials listed. Any material found in these tables is considered to be hazardous. The tables can be viewed on OSHA s Web site ... 

The OSHA tables of permissible exposure limits (PELs) for air contaminants, found in Subpart Z, Toxic and Hazardous Substances, 1910.1000. Contains Tables Z-1, Z-2, and Z-3. 

In the United States, the Occupational Safety and Health Administration (OSHA) has established legal standards for some toxic substances. Title 29, Code of Federal Regulations, Part 1910.1000 contains tables of Permissible Exposure Limits (PELs). The PEL...
