Hi there i've just discovered that i have green mould on my mattress. Is this as toxic and scary as the black mould? We also have a leak in our roof, we are renting. Is there any way we can test to see if there is mould ourselves or would we need to get someone in? I have mcs so im pretty vulnerable and dont want to get worse. The mcs i believe was brought on my a chemical exposure over a few months at work, but you never can be sure. Our compost container does grow black mould on occasion, so perhaps thats indicative of black mould spores in the air. Sigh, one thing after another lately!
