Cooking-Derived Organic Compounds Shape Bacterial Communities on Household Surfaces.

ABSTRACT: Understanding the factors influencing chemical and biological constituent accumulation on indoor surfaces is crucial, especially as individuals spend approximately 90% of their time indoors and frequently interact with these surfaces. However, the temporal relationships between these constituents remain unclear, as most field studies have relied on single-time snapshots and seldom examined the interplay between chemical and biological dynamics. We conducted a month-long spatiotemporal field study across 20 households in Hong Kong to investigate the factors influencing chemical and biological constituents on common indoor surfaces. Among the 16 household- and occupant-related factors analyzed, routine oil-based cooking was the primary driver of microbial diversity and composition on indoor
