  abstract = {{R}efined exposure assessments were realized for children, 7-9 yrs, in the mining/smelting city of {O}ruro, {B}olivia. {A}erosols ({PM}>2.5, {PM}1-2.5, {PM}0.4-1 and {PM}0.5) and dust (separated in different particle size fractions: 2000-200 mu m, 200-50 mu m, 50-20 mu m, 20-2 mu m and <2 mu m) were sampled on football fields highly frequented by children in both the mining and smelting areas. {T}race element concentrations ({A}g, {A}s, {C}d, {C}u, {P}b, {S}b, {S}n and {Z}n) in each size fraction of dust and aerosols, lung bioaccessibility of metals in aerosols, and gastric bioaccessibility of metals in dust were measured. {E}xposure was assessed considering actual external exposure (i.e. exposure pathways: metals inhaled and ingested) and simulated internal exposure (i.e., complex estimation using gastric and lung bioaccessibility, deposition and clearance of particles in lungs). {S}ignificant differences between external and simulated internal exposure were attributed to dissemblances in gastric and lung bioaccessibilities, as well as metal distribution within particle size range, revealing the importance of both parameters in exposure assessment.},
