Does all-purpose sand contain fungicide/antimicrobials?

I bought a bag of all-purpose sand to inoculate with microbe/mycorrhizal tea and fill my guerrilla gardening seed pills with.
Does anyone know if all-purpose sand usually contains fungicides or microbe killers? I reckon it's "sanitized" somehow but I wonder to what extent that effect lingers or if it's enough to overpower the microbes in my wonderful microbe tea.

Thanks in advance!
