Three POP species were measured in indoor dust from the homes of asthmatic and non-asthmatic children.
The concentrations of BDE-47/-99/-209, PCB-8/-49 and p,p’-DDE were significantly higher in the case group.
p,p′-DDE showed positive association with childhood asthma occurrence.
Hal-POP exposure via ingestion of indoor dust was not associated with non-carcinogenic health risks.
