“…14.7 ± 7 mg.Kg -1 DW for cladodes 2 planted vertically) were observed in the case of root exposure to Pb-FAP. Even if the modalities of cladode and root exposure to Pb-fluorapatite differs, our results are in line with previous studies indicating that atmospheric deposits on the aerial parts of plants may represent a major contamination pathway for metals (Dalenberg and van Driel, 1990;Feng et al, 2011;Uzu et al, 2010;Xiong et al, 2014). Interestingly, a translocation process in the whole cactus (including the nopalitos that developed during the experiment) took place only for cladodes that were grown on the contaminated soil.…”

The contamination of edible leafy vegetables by atmospheric heavy metal-bearing particles is a major issue in environmental toxicology. In this study, the uptake of lead by cladodes of Opuntia ficus-indica (Ofi), traditionally used in Mexican cuisine and in livestock fodder, is investigated after a 4-months exposure of either cladodes or roots to synthetic Pb-fluorapatite particles. Atomic Absorption Spectroscopy (AAS) for the quantitative analysis of Pb levels, Scanning Electron Microscopy coupled with Energy Dispersive X-Ray Spectroscopy (SEM-EDX) for the examination of the cladode surface and fate of particles, and Micro-X-ray fluorescence (μXRF) measurements for elemental mapping of Pb in cladodes, were used. The results evidence that foliar contamination may be a major pathway for the transfer of Pb within Ofi cladodes. The stomata, areoles, and cuticle of cladode surface, play an obvious role in the retention and the incorporation of lead-bearing apatite, thus revealing the hazard of eating contaminated cladodes. The possibility of using series of successive cladodes for biomonitoring the atmospheric pollution in arid and semi-arid regions is also rapidly discussed.

“…Lead can remain in the soil over several years and can be taken up by plants via the roots. However, Dalenberg and van Driel (1990) have calculated that 73 to 95% of the total 210 Pb content of field crops are derived from aerial deposition on leaf surfaces.…”

Radiocarbon, Trace Elements and Pb Isotope Composition of Pine Needles From a Highly Industrialized Region in Southern Poland

We determined the chemical composition of pine needles to monitor environmental contamination in an urban forest environment in the most industrialized part of southern Poland. The concentrations of radiocarbon (14C), trace elements (Cr, Co, Ni, Cu, Zn, Rb, Sr, Ba, Ce, Pb) and the Pb isotope composition were measured in needles from Pinus sylvestris L. growing in nine urban forests near five factories. The investigated young pine needles were collected in January 2013 and September 2013, respectively. 14C concentration was determined by liquid scintillation counter, trace elemental concentration and Pb isotope ratio were determined by ICP-MS and MC-ICP-MS, respectively. Analysis of trace metal pollution is based on the assumption that element concentrations in tree foliage represent element availability in the environment. Different space-time patterns of element accumulation in pine needles were observed. The variation in isotopic composition reflects a mix between different anthropogenic sources.

“…Yang et al [ 44 ] studied on the main sources of lead on grain crop (wheat) samples with isotopes and found that atmospheric fallout is a more significant source of Pb concentration in wheat grains than in soil. Dalenberg and Driel [ 45 ] have estimated that dustfall contributes > 90% of Pb contamination to wheat grains. Shang [ 23 ] studied Pb isotopic compositions of above-ground (stem and leaf) and below-ground (root) parts of vegetables including radish, lettuce, ginger and chives in the Chengdu area, with results indicating that 206 Pb/ 207 Pb ratios of vegetable leaves were very similar to those of dustfall, with the Pb isotopic composition of rhizosphere soil also being similar to that of vegetable roots.…”

This study detailed a complete research from Lead (Pb) content level to ecological and health risk to direct- and primary-sources apportionment arising from wheat and rice grains, in the Lihe River Watershed of the Taihu region, East China. Ecological and health risk assessment were based on the pollution index and US Environmental Protection Agency (EPA) health risk assessment model. A three-stage quantitative analysis program based on Pb isotope analysis to determine the relative contributions of primary sources involving (1) direct-source apportionment in grains with a two-end-member model, (2) apportionment of soil and dustfall sources using the IsoSource model, and (3) the integration of results of (1) and (2) was notedly first proposed. The results indicated that mean contents of Pb in wheat and rice grains were 0.54 and 0.45 mg/kg and both the bio-concentration factors (BCF) were <<1; the ecological risk pollution indices were 1.35 for wheat grains and 1.11 for rice grains; hazard quotient (HQ) values for adult and child indicating health risks through ingestion of grains were all <1; Coal-fired industrial sources account for up to 60% of Pb in the grains. This study provides insights into the management of grain Pb pollution and a new method for its source apportionment.
