“…On the contrary, the values obtained for lead are considerably lower than the obtained ones in India (Singh et al 1997;Swarup et al 2005), Argentina (Rubio et al 1998), Spain (Rodríguez Rodríguez et al 1999, Turkey (Simsek et al 2000;Ayar et al 2009), Romania (Serdaru et al 2001), Croatia (Pavlovic et al 2004), Chile (Muñoz et al 2005) or in Mexico (Rodríguez Fuentes et al 2008). The difference is a great deal more pronounced by the worrying results registered by Lopez Mahia et al (1991) in Spain, for Santos et al (2004) in Brazil, Baranowska et al (2005) in Poland and Swarup et al (2005) in India.…”

“…It has been proved that cadmium accumulates in plants of contaminated industrial areas, and in this way, it enters the animals to accumulate in tissues, and it is secreted in the milk (Rubio et al 1998;Parkpian et al 2003). However, sometimes milk coming from much polluted areas showed cadmium values lower than those found in areas with low environmental pollution (Caggiano et al 2005).…”

The levels of cadmium and lead in 36 raw bovine milk samples were analysed. These samples come from seven farms with a semi-extensive grazing system and were collected between the autumn of 2007 and the winter of 2008. All the farms were located in Asturias (Spain), a zone of great industrial and mining activity in the proximities of the Caudal River. The samples were collected in sterile precleaned polypropylene tubes and frozen until the analysis. After a lyophilization process, the samples were treated with nitric acid and microwave treatment. Cadmium and lead determinations were carried out using inductively coupled plasma mass spectrometry with sensibility under 0.2 ppb for liquid matrix. The lead content was found to vary from 0.71 to 16.06 μg/kg wet weight (w.w.), and the cadmium was lower than 2 μg/kg w.w. The levels of lead in milk are higher in those farms near zones of storage of mining waste depots, thermal power and areas with high levels of traffic. All the values found are in concordance with research carried out at non-polluted areas, and those for the lead are well below the European Union limitations.

“…Generally, the low levels of Pb in the offals and muscles of the mentioned food animals could be due to the fact that, Pb accumulates in bone and the metal concentration increases with age (Caggiano et al, 2005;Rubio et al, 1998).…”

“…Cmax was maximum at 20 HALO (1.57± 0.21 μg/mL) and minimum at 8 HALO (0.84±0.06 μg/ mL). Such as it happened during the winter trial (Valtorta et al 2003), the values were much higher than the average 24 ng/mL lead found in milk by Rubio et al (1998) in a survey performed in the same area. Cows in that report had not received any exogenous lead.…”

The objective of this study was to investigate circadian variations of blood and milk lead toxicokinetics in dairy cows in summer. Twenty lactating Holstein animals were randomly assigned to four treatments corresponding to different hours after onset of light (HALO): 2, 8, 14, and 20. Cows received a single intravenous administration of 2.5 mg/kg lead as lead acetate. Blood and milk samples were taken and analyzed by atomic absorption spectrophotometry. For each toxicokinetic parameter, a one-way analysis of variance (ANOVA) was performed to outline the existence of daily variations. Significant blood differences as a function of HALO were found for the hybrid constant of distribution (alpha), hybrid constant of elimination (beta), elimination half-life (t(1/2)beta), area under the curve (AUC), volume of distribution at steady state (V(ss)) and clearance (Cl(B)) (p<0.05). Half-life of elimination presented two peaks at 2 and 14 HALO. Milk data showed significant differences for maximum concentration and AUC (p<0.05). The ratio AUC(milk)/AUC(blood) was utilized to estimate penetration of lead in milk. It differed significantly throughout the day (p<0.05). Milk data for the significant parameters could be fitted to circadian rhythms. No circadian rhythms were detected in blood parameters or in the ratio AUC(milk)/AUC(blood).
