If you can get red lava rock you can be sure it's safe, a bunch of hobbyists in my country uses it for bio (myself included) . It has great charactheristics, it's very porous, light in weight, doesn't clog quickly, has some iron, and one very important thing... it's really really cheap. When I need some biomedia, I just by a big piece (for 3 dollars or so) and break it in pieces with a hammer, it's a lot softer than black lava rock. Or you can buy it ready to use.In my country is called tezontle, looks like this :

LUXURY LANDSCAPE - MULCH STONE GRAVEL COMPOST

Santa Fe Red Lava Rock

I only boil it to be sure it's clean.
