Can an oxigen sensor be mde into a long time gold locator??

[mextallion]

At work we have a oxigen sensor that measures air quality. It measures harmful air contents. To my knowledge (very limited) when you discover gold buried over 10 yrs it somehow has toxic contect which maybe could be measured by one of this sensors as you go over it.

Can anyone tell me if it is possible? Or maybe workable?
