Can I sue landlord for property damages and health issue.

You have the right to recover your damages and expenses from your landlord.

I'm handling a case very similar to this right now.  It sounds like you have a very good case for constructive eviction.  You can move, and get paid for your possessions, and you have a personal injury action too, provided you can document the mold condition, the damage to your property, and your physical symptoms. Take photos of all your belongings and the mold condition everywhere in your apartment, and take pictures in the basement, too. If you haven't already, go to the doctor. Demand that the landlord get a mold remediation company into your apartment IMMEDIATELY. In the case I am handling now, when the mold was tested the levels in the apartment were so high that the landlord insisted the tenant move out that same day, and the tenants were not allowed back into the apartment, because the environment was toxic.  Hire your own company to test, as well.  You can wait for your landlord to sue you for non-payment of rent and then counterclaim for all of the above, or you can start your own action. But act immediately. You could be living in a dangerous enviroment.
