Document Summary

Threshold limit value (tlv) twa = time-weighted average. Irptc stands for: international register of potentially toxic chemicals. Haart = highly active antiretroviral therapy = three-drug cocktail treatment for aids. 1% = 104 ppm = 107 ppb conversion. N2 (g) + 3 h2 (g) 2 nh3 (g) molar mass of ethanol (c2h5oh) = 46. 06 g/mol d= st m/s km/hr. Micro =1 g = 1 x 10 -6 g. Nano =1 n g = 1 x 10. The largest vol of these is 1. 0 l 1000 ml 1. 0 106 l >>1. 0 104 cm3. Chemicals causing changes in dna are known as: mutagens. A concentration of 21. 0 ppm for a gas in air is equal: 2. 10 10. A concentration of 51. 0 ppb for a gas in air is equal: 5. 10 10-2 ppm. Based upon tlv-twa which poses the most risk: ( answer is the least) Sulfur dioxide (2 ppm) carbon monoxide (2. 5 104 ppb) >>ozone (100 ppb) nitrogen dioxide (3. 0 10-4 %)
