Could black mold be causing my husband's illness in Dubai?« Back to Previous Page

It is very possible the mold is contributing to his persistent respiratory symptoms. The black, powdery substance you describe, especially on a cool exterior wall where condensation can form, is a classic indicator of a mold colony. Dubai's high humidity and constant AC use create ideal conditions for this, as the temperature difference between the cold interior and hot exterior walls causes moisture to accumulate.

His stuffy nose and dry cough that won't resolve are common reactions to mold spore exposure, particularly in a bedroom where exposure is prolonged for hours each night. You should treat this situation seriously and not attempt to clean it yourselves, as disturbing it will release a large cloud of spores.

For a case like this, you need a professional inspection from a company that can properly identify the mold type and its moisture source. In Dubai, look for a provider with a certified indoor environmental professional (CIEC) on staff and their own microbiology lab. This is critical because they should take air and surface samples to be analyzed in a lab, not just make a visual assessment. The lab report will confirm the species (e.g., Cladosporium, Aspergillus, or the more notorious Stachybotrys) and the spore count in your air, which determines the remediation protocol.

The remediation process itself must follow standards like the IICRC S520, involving containment of the area, HEPA filtration, and safe removal of contaminated materials. Once the source of the moisture is fixed and the mold is removed, his symptoms should gradually improve. Contact companies that offer both the diagnostic testing and the remediation work, and ask to see examples of their lab reports before you proceed.
