Table 2. Frequently encountered problems in environmental medicine practice (17): constellations of symptoms.
Problem | Relevant substance | Routes/sources of uptake | Environmental medicine anamnesis, physical findings | Indication for laboratory tests | Laboratory test/evaluation criteria | Environmental medicine relevance/evaluation |
Indoor mucosal irritation | Formaldehyde | Ambient air, indoor air (e.g., tobacco smoke), consumer products: furnishings, foam rubber, materials, disinfectants, etc. | Irritation of mucosa and airways | Symptoms and current exposure | Indoor air/BfR safe level 0.124 mg/m3 HBM: not indicated owing to endogenous production paints, cleaning |
|
Indoor mucosal irritation, central nervous disorders | Volatile organic compounds | Ambient air, solvents (e.g., from paints), new buildings, renovation | Irritation of mucosa and airways | Symptoms and current exposure | Indoor air/UBA reference and threshold values (16) |
|
Allergy, infection, and/or intoxication from indoor mold | Mold spores and components | Airways, skin | Irritation of mucosa and airways, immune status: aspergillosis or asthma, dyspnea and/or pulmonary infiltrates | Symptoms and current visible exposure in inhabited rooms | Possibly indoor air and material samples, UBA (25) |
|
Sick building syndrome (SBS) | No specific substance | Indoor air/mucosae | Irritation of ocular mucosae and upper and lower airways, non-specific symptoms | Symptoms and current exposure, other people also affected | Site inspection and standardized interview regarding interior perceptions and health problems | Symptoms are as a rule primarily related to factors from the following areas:
|
Electrosensitivity | High-frequency electromagnetic fields, e.g., from cell phone masts | Field exposure, transdermal | No acute symptoms, no warming-up effect expected at exposure below threshold values | Interior space/Ordinance on Electromagnetic Fields*1 |
|
|
Multiple chemical sensitivity | – | – | No typical constellation of symptoms known, neurovegetative symptoms frequent | Typical symptoms and history of specific exposure |
