“…However, injudicious application to soil may give rise to accumulation of heavy metals in the top soil (Eid, 1984;El-Nennuh et al, 1982;Williams et al, 1980;Andresson and Nilsson, 1973). High levels of heavy metals in soil may inhibit crop production, or increase metal uptake without reduction in yield ( Unger and Fuller, 1985;Vlamis et al, 1985;Smilde, 1981;Webber, 1972). One of the major concerns is heavy metals enrichment in edible parts of the crop, creating hazards to animal and human health.…”

Total content of Fe, Mn, Zn, Cu, Pb, Cd, Ni and Co in soils irrigated with sewage effluent increased with increasing years of using sewage effluent in irrigation. Iron and Co applied to the soil from sewage effluent were immobilized mainly in unavailable form; Pb, Cd, and Ni in moderately available form; and Mn, Zn, and Cu in highly available form. The concentrations of Fe, Mn, Zn and Cu in tops of alfalfa and leaves of corn grown on these soils increased substantially with increased levels of available metal content of the soil, while those of other metals were little affected. As for orange, continuous increase in leaves metal content with time was found for Fe, Mn, Zn, Co and Cd. The concentrations of Cd, Co, Ni and Pb in corn grains and orange fruits were several times higher than normal, and this reduces their suitability for human consumption.

“…The Ni concentration in Bouteloua spp. was greater than other gramineae species grown with biosolids (Evanylo et al 2005;Unger and Fuller 1985). However, these values are less than or equal to the maximum tolerable dietary level for cattle.…”

“…Hernandez et al (1991) demonstrated that metal and nutrient absorption by crops (barley and maize) in a calcareous soil amended with biosolids depends on the vegetal species. Moreover, Unger and Fuller (1985) noted that heavy-metal uptake from barley in arid soils amended with biosolids could be lower than in other climates because of neutral or slightly alkaline pH of these soils.…”

“…There have been few studies concerning metal uptake in native species of arid or semiarid soils amended with biosolids (Fresquez, Francis, and Dennis 1990;Fresquez et al 1991;Hernandez et al 1991;Unger and Fuller 1985). The levels of copper (Cu), manganese (Mn), iron (Fe), and zinc (Zn) extracted with diethylenetriaminepentaacetic acid (DTPA) increased linearly with increased sludge application rate during the first growing season, while the levels of cadmium (Cd) or lead (Pb) did not significantly increase after the first three growing seasons.…”

An experiment was conducted in three wild grass species of Bouteloua genus to compare the effect of application of biosolids on the accumulation of heavy metals, biomass production, and nutrient uptake. Biosolids were applied at rates of 0, 3.5, 7, and 10.5 Mg ha −1 to two different soil types collected from the southern Chihuahuan Desert. The shoot biomass of B. gracilis (BOGR) and B. scorpioides (BOSC) was two to three times greater than the control while in B. curtipendula (BOCU) in was 75% in both soils. In BOGR, nitrogen and phosphorus uptake were 4-4.5 times greater than the control in calcareous soil. With few exceptions, there was no significant difference of heavy-metal concentrations (copper, chromium, arsenic, nickel, and zinc) in the plant tissues compared to the control. The application of biosolids showed interspecies variability in growth response and nutrient uptake with a minimal risk of heavy-metal uptake for Bouteloua wild species.
