What are long term effects of exp. to black mold, formeldehyde, automotive fumes? we live in a bldg. and rv exp. us to these constantly. i have been sick with upper resp. illness since. we are moving to a new home but are there long term effects?

Depends: There are hundreds of black molds but only one I know of with toxic effects. You can be allergic to any such exposure but that is a transient issue that ends when exposure ends. Formaldehyde/automotive fumes are also simple irritants. Your system may or may not be more sensitive than others. I would neither assume your sickness is related or exclude the possibility. Moving is a good idea
