Environmental exposures are major modifiable determinants of human aging, yet the evidence remains fragmented across organ-agnostic summaries and rarely confronts population inequity. Here we present an exposomic atlas of pan-organ aging in ~300,000 UK Biobank adults, mapping 164 environmental and behavioural exposures onto biological aging of the whole body and nine organ subsystems. Comprising 1,476 systematically tested exposure-subsystem associations, the atlas reveals that environmental effects on human aging are pervasively organ-specific, with 65.9% of exposures acting divergently across organ subsystems. This landscape resolves into nine navigable modules that preserve organ selectivity, predict 23 major age-related diseases, and expose distinct dimensions of health inequity. In-silico analyses further show that priorities for ameliorating aging are target-dependent rather than universal, diverge markedly from the whole-body ranking (Kendall's {tau} = 0.52 to 0.39), reorder substantially across population strata, with findings externally validated in an ethnically distinct cohort. The atlas establishes an organ-resolved and target-aware foundation for precision environmental health.
