Poeira de Aspirador de Pó: Riscos à Saúde e Estratégias de Mitigação

Vacuum dust concentrates indoor pollutants; handling poses exposure risks.

Hazard Categories

• Allergens: Dust mite feces (Der p 1), pet dander, pollen, mold spores → IgE-mediated allergy/asthma.
• Irritants: Fine particulates (PM₂.₅), cleaning residues, fiberglass → cough, eye/nose/throat irritation.
• Pathogens: Bacteria (E. coli, Staph), fungi (Aspergillus) — viable in dust reservoir.
• Toxicants: Lead (pre-1978 paint), asbestos (vermiculite, old insulation), flame retardants (PBDEs), phthalates, pesticides.
• Endotoxins: Gram-negative bacterial LPS → airway inflammation.

Exposure Moments

• Emptying bag/canister (aerosolization).
• Filter cleaning/replacement.
• Exhaust leakage (non-HEPA).

Mitigation

• True HEPA filtration (H13/H14) on exhaust.
• Bagged > bagless (less cloud on emptying).
• Empty outdoors or into sealed bag; wear N95 if sensitive.
• Wet-wipe canister; wash filters per manual.
• Ventilate during/after vacuuming.
• Upgrade to sealed-system HEPA vacuum (Miele, Sebo, high-end Dyson/Shark).

Noise and Ergonomics

70–80 dB → hearing risk with prolonged use; repetitive strain — use self-propelled, adjustable handle.

Vacuuming improves indoor air quality *if* emissions are controlled.
