Comprehensive Screening of Pollutants in Household Dust Using High-Resolution Mass Spectrometry with Enhanced Chromatographic Resolution

Individuals spend a good portion of their lives indoors and are regularly exposed to a variety of harmful substances. Hazardous chemicals are ubiquitous, and chronic exposure via inhalation, dermal uptake, or ingestion can be detrimental to human health.The sources of pollutants in homes and places of employment include, but are not limited to, textiles, electronic devices, and building materials.
