“…Lead in water may be originated from soils, rocks, fallout, dust or vehicular exhausts (Quarteman 1986). It is a heavy metal widely used in some fertilizers for sugar cane cultivation, being added in NPK fertilizers (Angelotti-Netto et al 2004).…”

“…Although not analyzed in the sediments, the detection of lead in Odonata larvae is an indicative of the sediment contamination, because these aquatic organisms live and feed in this aquatic compartment. High concentrations of Pb can cause severe damages to aquatic and terrestrial animals due to bioaccumulation processes (Quarteman 1986). Its concentration values found in the present work can be considered high, especially in the case of the São Vicente stream (S6) where concentration are higher than the permitted values for soils in Brazil.…”

The use of fertilizers, containing different metals ions such as lead(II), chromium(III), cadmium (II), copper(II) and zinc(II), in the soil, for sugar cane cultivation, may cause impacts on the hydric resources of the adjacent areas. The scope of this study was to evaluate the impacts of sugar cane cultivation based on metal concentrations in sediments and dragonflies (Odonata). The bioavailability of such metals was determined in ten Neotropical streams. Six streams were located on areas with sugar cane cultivation, without riparian vegetation (classified as impacted area) and four streams were located on forested areas (reference sites). The results showed that there are high concentrations of metals in the sediments and dragonflies in streams located on impacted areas. The contamination by metals of aquatic insects of terrestrial adult life cycle, as Odonata organisms, represents a dangerous link for the transference of metals to upper trophic levels, as fishes, reptiles, birds and mammals.

“…Thus, in the present study also the Se level in adult females tend¬ ed (P=0.04) to be lower than in the calves. Only small amounts of As, Cd, Pb and inorganic Hg are secreted in milk (Anke, 1986;Kostial, 1986;Quarterman, 1986;Clarkson, 1987). The results presented in Table 1 are also in accord with these findings, since As, Cd, Pb, and Hg were not found in higher levels in calves than in adults.…”

Reindeer (Rangifer tarandus tarandus) grazing the Rybatsjij Ostrov peninsula, north western Russia, northeast of the industrial towns of Nikel and Zapoljarnij, were analysed for hepatic concentrations of trace elements [arsenic (As), cadmium (Cd), chromium (Cr), cobalt (Co), copper (Cu), lead (Pb), mercury (Hg), nickel (Ni), selenium (Se), and zinc (Zn)] by atomic absorption spectroscopy. The median (range) concentrations (jig/g wet weight) deter¬mined in liver samples from 40 reindeer with even sex ratio and representation from different age classes were As 0.035 (0.017-0.048), Cd 0.34 (0.15-1.2), Cr 0.008 (<0.002-0.022), Co 0.09 (0.06-0.12), Cu 98 (29-220), Pb 0.56 (0.23-1.0), Hg 0.16 (0.08-0.31), Ni 0.027 (<0.020-0.13), Se 0.88 (0.56-1.3) and Zn 37 (24-105). The concentrations of Cd increased and Ni decreased with age. The measured liver concentrations were below levels of toxicological sig¬nificance to the animals. It can be inferred that there is no risk with the measured trace elements to human health associated with the consumption of meat from these reindeer

“…The value for ingested soil appears realistic under Irish conditions (McGrath et al, 1982) but that for maximum tolerable level of Pb in herbage may appear slightly conservative. Severe instances of poisoning in cattle do not normally occur below 300 mg/kg Pb in diet (Quarterman, 1986). This is equivalent to about 6000 mg/kg Pb in soil where soil constitutes 5% of ingested food.…”
