Relative abundances of clones affiliated to fungal classes in the studied dust and building material samples. Sample name abbreviations: In: index building Re: reference building, 1: Location-1, 2: Location-2, a: pre-remediation sample, b: post-remediation sample; Dust comb: combined data from settled dust samples; BM-1: building material pool from Index-1 building. Construction of clone library from the Index-2 building material pool failed.
