I'm new on this website can any of you be my friends

Put in your search, Tests for Nitrogen Dioxide. I found one for Silage Gasses -moistened potassium iodide papers. I didn't look too much further but I think there was a lot of info including information about how it affects us. I read Nitrogen Dioxide maybe the cause of SIDS!! Sudden Infant Death Syndrome! ND is in the air, too much of it can kill! Pollution is the main problem , and there are a number of man -made things that cause it, like combustion engines(I'm assuming that means cars)that we can eliminate to improve our air! ) Hope this helps! Fascinating subject! And science is not my specialty!! I;m adding you as a friend! Thanks for asking!! Great that you are doing so well in school! Keep it up! Maybe you can help us clean up our dirty air!!
