The use of untreated urban wastes and domestic sewage contaminated water for the irrigation of agricultural soils is on the rise particularly in the developing countries and is a public health concern with regards to the consumption of vegetables and fruits produced in them which may indirectly accumulate heavy metals in their edible portions. Using the atomic absorption spectrophotometry (AAS), concentrations of Ca, Mg, Na, K (essential bulk elements), Pb, Cd, Cr, Ni, Cu, Zn, Co and Fe (trace elements) were determined in 3 designated areas within the catchment area of River Jakara in Kano Nigeria. Samples were collected from two depths 0-15cm and 15-30cm to cover both dry and wet seasons. The mean concentrations of elements obtained ranged from 0.026 mg/g Cd to 46.83 mg/g Fe and occurred in the magnitude of Fe > Ca > K > Na > Pb >Zn > Co > Cu >Cr > Ni > Cd. The concentrations of the trace elements in the soils in the two depths exceeded the international recommended permissible limits establishing the pollution of the irrigation soils with the trace elements investigated. Based on the findings, it is recommended among others that the relevant organ of government should find an alternative farmland for the farmers within the catchment area of River Jakara where unpolluted waste sources can be utilized for the irrigation of vegetables.

Poplar and willow demonstrate great potential for the phytoextraction of trace elements (TEs) from soils. In most cases, these species are managed as short-rotation coppice, producing high woody biomass yields, which could provide a valuable contribution toward reducing greenhouse gas emissions in the atmosphere. In the current study, we compared the TE extraction and CO2 sequestration rates in a four-year field trial in Southern Italy of two arboreal species (willow and poplar). The results show that, once established in the study area, willow extracted more Cd and Cu and less Pb than poplar. The two species demonstrated the same average Ni and Zn extraction rates. Greater biomass yields in poplar suggest that this species was able to fix greater amounts of CO2 (28.7 Mg ha−1 yr−1) than willow (24.9 Mg ha−1 yr−1). We argue that the choice of the species to be used in phytoextraction should first be made considering the TE-specific affinity and phytoextraction rates. For TEs whose extraction rates were the same (i.e., Ni and Zn), poplar is to be preferred because of its ability to fix greater amounts of CO2 than willow.

Abstract. The atmospheric concentrations of 17 trace elements (Al, Ca, Cd, Cr, Cu, Fe, K, Li, Mg, Mn, Na, Ni, P, Pb, S, Ti and Zn) were measured by means of the "lichen-bag" technique in the Agri Valley (southern Italy). The lichen samples were collected from an unpolluted site located in Rifreddo forest (southern Italy). The bags were exposed to ambient air for 6 and 12 months. The exposed-to-control (EC) ratio values highlighted that the used lichen species were suitable for biomonitoring investigations. The results showed that the concentrations of almost all the examined trace elements increased with respect to the control after 6–12 month exposures. Furthermore, Ca, Al, Fe, K, Mg and S were the most abundant trace elements both in the 6 and 12 month-exposed samples. Moreover, principal component analysis (PCA) results highlighted that the major sources of the measured atmospheric trace elements were related both to anthropogenic contributions due to traffic, combustion processes, agricultural practices, construction and quarrying activities, and to natural contributions mainly represented by the re-suspension of local soil and road dusts. In addition, the contribution both of secondary atmospheric reactions involving Centro Olio Val d'Agri (COVA) plant emissions and the African dust long-range transport were also identified.
