The Safe Drinking Water Quality Standard for nitrate nitrogen (NO3--N) is 10.0 mg/L. Convert this into nitrate (NO3-) in ppm, mmol/L, and normality (N). (Given: N=14, O=16) The highest maximum one-hour ozone (O3; molecular weight = 48) concentration in Houston during 1999-2001 was 175 ppb. Convert this into mg/m3 at STP. The National Ambient Air Quality Standards for 1-hr O3 is 155 mg/m3. (Given: mg/m3 = ppm*MW/22.4).

The national ambient air quality standard in the US for PM10 is 150 μg/m3, on an annual basis. Every time that you breathe you take in approximately 5 L of air. Assuming that air contains 185 μg/m3 of PM10, how many grams of PM10 would the person inhale per day, assuming that the person takes 12 breaths per minute, and that all particles enter and are retained somewhere in the respiratory system. Express your answer to three decimal places.

Suppose the average concentration of NO2 is measured to be 85 micrograms/m^3 at 25 degree Celsius and 1 atm. MW of N02 is 46 grams. 1. Express that in standard ppmv at 1 atm of pressure and 25 degree Celsius. 2. Does this exceed the air quality standard of 53 ppbv at 25 degree Celsius and 1 atm? 3. At the elevation of Denver, the pressure is about .82 atm. Express the NO2 standard of 53 ppb in micrograms/m^3 at...

Nitrogen dioxide (NO2) is toxic by inhalation. A scientist claims that the population mean nitrogen dioxide level in West London is higher than 30 parts per billion and collects the NO2 levels for 36 randomly selected days. The results show an average of 32.86 and the standard deviation of 12.72 parts per billion. Historical data show that the nitrogen dioxide levels follow a normal distribution with a standard deviation of 12 parts per billion. (a) (3 pts) Construct a 95%...

S-4. In the indoor air of the room described in S-3 above, nitrogen dioxide (NO2) is continuously released from a combustion source and destroyed by photochemical reactions, at a constant rate of 40 μg/min. The steady state concentration of NO2 in this room is measured to be 20 μg/m3. Calculate its residence time.
