Now, "I" am posting this because it may have something to do with geological changes. A couple of the incidents in the video are probably just the run of the mill leaks like the refrigerant one. But the most interesting one is the one with the low concentrations of Hydrogen Sulfide. Because from http://en.wikipedia.org/wiki/Hydrogen_sulfide:

Hydrogen sulfide (British English: hydrogen sulphide) is the chemical compound with the formula H2S. It is a colorless, very poisonous, flammable gas with the characteristic foul odor of expired eggs perceptible at concentrations as low as 0.00047 parts per million. It often results from the bacterial breakdown of organic matter in the absence of oxygen, such as in swamps and sewers; this process is commonly known as anaerobic digestion. It also occurs in volcanic gases, natural gas, and some well waters. The human body produces small amounts of H2S and uses it as a signaling molecule.

Now, the most likely explanation is that the H2S is escaping from the sewer system, but what would cause structural failure in the sewer system that would allow the gas to escape? Normal wear and tear? maybe, make that probably. Its just something to keep an eye on, maybe something, maybe nothing.

Chemical and radiation experts were called in after the unexplained death of a man found inside a tent. A passer-by discovered the body while walking in the Port Meadow area of Wolvercote, Oxford, at about 12:25 GMT. A strong chemical odour prompted the area to be cordoned off and specially-trained officers to be brought in.

Thames Valley Police said it was likely the chemical was hydrogen sulphide, which can be fatal within minutes if breathed in. Members of the public were warned to avoid the cordoned-off area. A number of local footpaths have also been closed. Police said although the man's death was being treated as unexplained, there appeared to be no suspicious circumstances. Supt Steve Hockin said: "Early indications are that the chemical involved in the death of the man is hydrogen sulphide, but emergency services are working together to examine the scene and recover the body as safely as possible."
