Air chemical analysis "homemade"?

AI Thread Summary
Air analysis around steelworks can be conducted to assess pollution levels, but reliable results typically require expensive equipment and expertise. For those seeking affordable options, purchasing a basic air quality meter online can provide some insights, particularly for specific pollutants like CO or NOx. It's also advisable to compare readings from different locations, such as urban centers, where pollution may be higher. In addition, contacting the steelworks for emission data or checking with local government agencies that monitor air quality can yield valuable information. However, concerns remain about the accuracy of sporadic measurements, as pollution levels may vary significantly over time and distance from the source, potentially leading to an incomplete understanding of local air quality.

I have a steelworks nearby my home. Is it possible to perform an air analysis in order to know how much the air is polluted? Which instrument do I need ? Are there cheap possibilities? Thanks a lot in advance for your help!

Sorry, no way of making it cheaply, reliably, without expensive hardware and years of training.

Thanks for your reply. Do you know however, how it should be performed?
 
What are you afraid of? If you are worried about something specific, like CO or NOX, go to ebay and by a cheap meter. Also do some measurements in the city center, it will probably be worse there.

You can also call the steelworks and ask if they can provide information on the emission levels. Probably there is also an external (government) agency that will measure emissions every once in a while. This might be information that must be made available to the public if they ask for it (in the US it is the freedom of information act I think).
 
I'm just worried about the steelwork near my home. Even if somebody measure emissions every once in a while, two problems can arise:
1) In some particular time frame (for example night) the steelwork could also emits more than usual pollution; it means that emissions control which are eventually done every once in a while could not really fully correspond to the reality.
2) The level of pollution, I think, is not the same in all the area. If I live near the steelwork maybe there is more pollution with respect to someone living far away. So a given measure is however not reflecting the effective pollution in every housing units.
However , thanks for your interest.
 
I want to test a humidity sensor with one or more saturated salt solutions. The table salt that I have on hand contains one of two anticaking agents, calcium silicate or sodium aluminosilicate. Will the presence of either of these additives (or iodine for that matter) significantly affect the equilibrium humidity? I searched and all the how-to-do-it guides did not address this question. One research paper I found reported that at 1.5% w/w calcium silicate increased the deliquescent point by...
