The maximum length of time you can claim unemployment benefits is 26 weeks. If the unemployment rate is 5% or lower, you can claim benefits for up to 12 weeks. For every .5% increase in the unemployment rate above 5%, a week is added to the duration of benefits.
1 Non-smokers living away from urban areas have normal carbon monoxide levels in the blood stream of 0.4% to 1.0%.  Carbon monoxide levels of 1% to 5% may be considered normal if a person lives in a busy urban or industrial setting.
An ambient carbon monoxide level of 100 parts per million (ppm) produces 16% HbCO at equilibrium, which is sufficient to produce clinical symptoms. It also binds to intracellular carriers of oxygen, causing tissue asphyxiation. Carbon monoxide binds even more avidly to cardiac myoglobin than to haemoglobin.
