Raw safety data returned.","data":{"risk_level":"moderate","summary":"Fungal spore mix represents the complex aerosol of fungal spores, hyphal fragments, and associated metabolites (mycotoxins, glucans, allergens) found in indoor air. The dominant genera are Aspergillus, Penicillium, Cladosporium, and Alternaria, which together account for >90% of indoor fungal spores. Typical indoor concentrations: 200-2,000 CFU/m3, with water-damaged buildings reaching 10,000+ CFU/m3. WHO guidelines recommend indoor levels below outdoor levels as an indicator of acceptable air quality; various authorities suggest <500 CFU/m3 total indoor fungi. Health effects of chronic exposure are well-documented: allergic rhinitis (10-30% of general population sensitized to mold), asthma exacerbation (IOM 2004: sufficient evidence for association), hypersensitivity pneumonitis (rare but severe), and possible chronic fatigue/neurological symptoms (evidence limited). The 2004 IOM report and 2009 WHO guidelines conclude that damp indoor environments are associated with adverse respiratory health, but specific dose-response relationships remain poorly characterized due to the complexity of the exposure (mixture of species, metabolites, particles). NIOSH recommends source control (moisture management).","source_refs":["aletheia_fungi_batch_2026"]},"meta":{"synthesis_version":"n/a","timestamp":"2026-05-14T01:22:10.354Z"}}
