personally, i try to avoid inhalation when disposing of a crt

fyi, crt phosphors are :
color compounds type designation
red = yttrium oxide-sulfate activated with europium P22R
green = zinc sulfide and copper P22G
blue = zinc sulfide silver P22B
in b/w crts the phosphor is a mix of zinc cadmium sulfide and zinc sulfide silver P4
