  abstract = {{O}puntia ficus-indica ({O}fi) is a long-domesticated cactus that is widespread throughout arid and semiarid regions. {O}fi is grown for both its fruits and edible cladodes, which are flattened photosynthetic stems. {Y}oung cladodes develop from mother cladodes, thus forming series of cladodes of different ages. {T}herefore, successive cladodes may hold some potential for biomonitoring over several years the local atmospheric pollution. {I}n this study, cladodes, roots, dust deposited onto the cladodes, and soil samples were collected in the vicinity of three heavily polluted sites, i.e., a fertilizer industry, the road side of a highway, and mine tailings. {T}he lead content was analyzed using atomic absorption spectroscopy ({AAS}) and inductively coupled plasma-mass spectrometry ({ICP}-{MS}). {S}canning electron microscopy coupled with energy dispersive {X}-ray spectroscopy ({SEM}-{EDX}) was used to characterize the cladode surfaces and the nature of dust deposit, and the lead isotopes were analyzed to identify the origin of {P}b. {T}he results show that (i) {O}fi readily bioaccumulates {P}b, (ii) the lead isotopic composition of cladodes evidences a foliar pathway of lead into {O}fi and identifies the relative contributions of local {P}b sources, and (iii) an evolution of air quality is recorded with successive cladodes, which makes {O}fi a potential biomonitor to be used in environmental and health studies.},
