That is difficult to answer, as it always depends on the concentrations. Since both methane and carbon monoxide are gases it is unlikely that the will linger for long on the land fill site.
Here some guidelines towards measured concentration and their acceptability:
CO
Occupational exposure limits
TLV: 25 ppm as TWA BEI issued (ACGIH 2006).
MAK: 30 ppm 35 mg/m³ Peak limitation category: II(1); Pregnancy risk group: B; (DFG 2006).
CH4
TLV: (aliphatic hydrocarbons gases, Alkane C1-C4) 1000 ppm (as TWA) (ACGIH 2005).
MAK not established.
The more dangerous of the two is clearly CO (carbon monoxide). CH4 is lighter than air and will proceed straight up to the sky.
It should be at LEAST 2,000 feet away from a structure, or you could catch your house on fire. By the way, if you haven't signed your land over to a gas driller yet, don't do it! It's dangerous, and you can catch cancer from it! Spread the word that gas drilling is bad, and if you support it, you are supporting the world coming to an end.
methane, nitrogen ,and carbon monoxide
Yes, the products of CH4 + O2 (Methane + Insufficient Oxygen) are water and carbon monoxide.
No. While frozen methane, carbon dioxide, and nitrogen do exist on Pluto, they are not metals.
Incomplete combustion means burning in a lack of air (not enough oxygen). If there is not enough oxygen available for all the carbon to turn into carbon dioxide (complete combustion), then some or all of the carbon turns to carbon monoxide. This happens with any hydrocarbon - we shall take methane as an example. During incomplete combustion methane gas burns with a yellow flame (unlike the clear blue flame seen in complete combustion). Carbon particles (sooty marks) may also be seen. methane + oxygen carbon monoxide + water. 2CH4(g) + 3O2(g) 2CO(g) + 4H2O(l)
no it means it was an incomplete combustion causing pure Carbon (carbon monoxide or sut).
methane, nitrogen ,and carbon monoxide
No. Natural gas is mainly methane (CH4). Carbon monoxide is CO.
Yes, the products of CH4 + O2 (Methane + Insufficient Oxygen) are water and carbon monoxide.
If it a complete combustion, there would be only carbon dioxide and water vapor present. Otherwise, carbon monoxide may present too.
Carbon dioxide, carbon monoxide, methane, and ammonia.
