  abstract = {{C}oral reef fishes represent an invaluable source of macro- and micro-nutrients for tropical coastal populations. {H}owever, several potentially toxic compounds may jeopardize their contribution to food security. {C}oncentrations of metallic compounds and trace elements ({MTE}s), and persistent organic pollutants ({POP}s, including pesticides and polychlorobiphenyls {PCB}s), totalizing 36 contaminants, were measured in coral reef fish from several {P}acific islands. {T}he objective of this study was to describe the spatial distribution of these compounds and contaminants in order to identify potential variables explaining their distribution at a {P}acific-wide scale. {T}o achieve this, we applied {B}oosted {R}egression {T}rees to model species-specific and community-level contaminant and inorganic compound concentrations at the scale of the tropical {P}acific {O}cean. {O}verall, using 15 easily accessible explanatory variables, we successfully explained between 60 and 87 % of the global variation, with fish body size being the most important correlate of {MTE}s and {POP}s concentrations in reef fish. {O}ur modeling approach allowed us to estimate and map the distribution of the community-level concentration of 19 contaminants and inorganic compounds at the scale of the equatorial and south {P}acific {O}cean. {S}patial patterns varied significantly depending on the compound, with modeled quantities per 100 g of fish flesh generally being higher in the central and southwest {P}acific than in the eastern part of the basin. {T}hese patterns were influenced by a combination of biological, environmental, anthropogenic and biogeographical variables. {O}verall, this approach represents an important step toward the estimation of concentrations of the main compounds on the basis of species identity and fishing location. {O}ur results enhance our understanding of the extent of contamination in the {P}acific while underscoring the urgent need for long-term and large-scale spatial monitoring of diverse compounds in this region.},
