I asked before about a thermometer that I broke yesterday. To summarize, I broke a mercury thermometer in my bedroom, which is a place where is difficult to have sure that I get rid of all mercury, but I cleaned the large amount without touching it.
However, I have more specific questions now. I discovered that I, by my lack of attention, have spread mercury along the house. I found a very tiny drop (really difficult to see) on the floor near to my desktop, which is in the living room, not in my bedroom. I also found a few same little drops in the bedroom, but it was really tiny. So, since I can assume that I will not be able to get rid of all mercury now, I have the following question:
- How much time mercury takes to evaporate?
I think that wait the mercury to evaporate it is the only way that I can get rid of them now. Also, I have to say that I live in a country which doesn't have a service to check the amount of mercury in the air of the house neither get rid of the mercury.
I found what maybe is more mercury tiny drops under a table in living room, but this time I tried to estimate the size of the possible drops.
Three really tiny mercury beads (zoom in if you could not clearly see the white points)
I know is it difficult to see, but I placed a piece of adhesive tape on the floor, which has the same size as my thumb's nail (about 1.4cm).
I don't know if is a good way to measure something, but I cut one of the three beads in a imagem editor and placed copies of it from on side until another. It takes about 30-40 copies to made the path. So, 1.4cm/30 results in each bead being at least about 0.47mm.
So, with this information, how many of that beads are needed to make the air dangerous?
