  abstract = {{S}evere polymetallic contamination is frequently observed in the mining communities of {B}olivian {A}ltiplano. {W}e evaluated hair trace elements concentrations at the population level to characterise exposure profile in different contexts of contact with mining and metallurgical pollution. {W}e sampled 242 children aged 7 to 12 years in schools from five {O}ruro districts located in different contexts of potential contamination. {H}air trace elements concentrations were measured using {ICP}-{MS} ({P}b, {A}s, {H}g, {C}d, {S}b, {S}n, {B}i, {A}g, {N}i, {S}e, {C}u, {C}r, {M}n, {C}o and {Z}n). {W}e compared concentration according to school areas and gender. {C}oncentrations were markedly different depending on school areas. {C}hildren from schools near industrial areas were far more exposed to non essential elements than children from downtown and suburban schools, as well as the rural school. {T}he most concentrated non-essential element was {P}b (geometric means ({SD}): 1.6 (1.3) mu g/g in rural school; 2.0 (2.3) mu g/g in suburban school; 2.3 (3.0) mu g/g in downtown school; 14.1 (2.7) mu g/g in the mine school and 21.2 (3.3) mu g/g in the smelter school). {B}oys showed higher levels for all non-essential elements while girls had higher levels of {Z}n. {H}air trace elements concentrations highlighted the heterogeneity of exposure profiles, identifying the most contaminated districts.},
