  abstract = {{M}ost available studies on lead smelter emissions deal with the environmental impact of outdoor particles, but only a few focus on air quality at workplaces. {T}he objective of this study is to physically and chemically characterize the {P}b-rich particles emitted at different workplaces in a lead recycling plant. {A} multi-scale characterization was conducted from bulk analysis to the level of individual particles, to assess the particles properties in relation with {P}b speciation and availability. {P}rocess {PM} from various origins were sampled and then compared; namely {F}urnace and {R}efining {PM} respectively present in the smelter and at refinery workplaces. {E}missions {PM} present in channeled emissions. {T}hese particles first differed by their morphology and size distribution, with finer particles found in emissions. {D}ifferences observed in chemical composition could be explained by the industrial processes. {A}ll {PM} contained the same major phases ({P}b, {P}b{S}, {P}b{O}, {P}b{SO}4 and {P}b{O} center dot {P}b{SO}4) but differed on the nature and amount of minor phases. {D}ue to high content in {PM}, {P}b concentrations in the {C}a{C}l2 extractant reached relatively high values (40 mg {L}-1). {H}owever, the ratios (soluble/total) of {C}a{C}l2 exchangeable {P}b were relatively low (< 0.02%) in comparison with {C}d (up to 18%). {T}hese results highlight the interest to assess the soluble fractions of all metals (minor and major) and discuss both total metal concentrations and ratios for risk evaluations. {I}n most cases metal extractability increased with decreasing size of particles, in particular, lead exchangeability was highest for channeled emissions. {S}uch type of study could help in the choice of targeted sanitary protection procedures and for further toxicological investigations. {I}n the present context, particular attention is given to {E}missions and {F}urnace {PM}. {M}oreover, exposure to other metals than {P}b should be considered.},
