Question

calculations Pollutants (20s) --solve the following 4 problems (5% each): co --A cigarette smoker has a 500 ppm CO in his lung for 30 minutes Assuming the HbC0 content reaches 40% of its equilibrium saturation value, estimate the percentage of HbC0 in his blood and possible impact of his health? NO_x: convert the mass concentration of NO_2 of 5,000 ug/m^3 to ppm at room condition (1 atm, 25 degree C). Biofuel-Base on the energy content of fuels in Ch. 7 what would be the break-even price of Ethanol if sells for $3.20/gallon? PMs --If coal with an ash content of 14% and a heating value of 10,000 is burned in a 40%-efficient 500 MW_e utility power plant, estimate the emission rate of flyash in ton/day if flyash ash ratio 10:1 and the PM removal system (electrostatic precipitator) can reach 99% removal efficiency.

Explanation / Answer

Enhanced sensitivity to digitalis induced ventricular tachycardia at 20% carboxyhemoglobin. Permissible limit is only 30 ppm for 8 hours and above 200 ppm leads to acute exposure. After reaching equilibrium saturation level, 35% of HbCO is present in the blood. It causes nausea, severe headache, dizziness, increasing pulse and respiration.
