“…For instance, the instrumental LOD values reported here in this work are between 10 and 45% below the ones previously reported elsewhere for the determination of Cd (0.3-1.0 µg L −1 ), Pb (1.0-3.0 µg L −1 ) and Se (2.0-7.0 µg L −1 ) in meat by inductively coupled plasma-optical emission spectrometry (ICP-OES) [24][25][26].…”

An analytical method for sample preparation and subsequent determination of Cd, Pb and Se in beef using aerosol dilution by inductively coupled plasma-mass spectrometry was developed. The use of high matrix introduction technology allowed the introduction of a complex sample into the plasma with higher content of total dissolved solids a residual acidity of 4% and better tolerance to matrix effects. Trueness was verified by the analysis of two reference materials. At the 95% significance level, results were statistically equivalent to the certified or informed values. Analytical precision expressed as relative standard deviation was less than 9% in all cases. After validation, a total of 12 beef samples from Uruguay were analyzed. Obtained levels for Cd and Pb were far below the maximum limits established by international regulations in all samples. Also, results showed that beef from this region is a good source of Se in the range 0.120-0.870 mg kg −1 with an interesting contribution to the daily intake of this essential element.

“…Liver damage, coming from an accelerated senescence, is described in mice chronically exposed to Al [ 9 ]. Furthermore, the liver appears to be an important storage organ for Al in steers [ 29 ]. The involvement of Al in the negative energy balance and subclinical ketosis in this case report is questionable.…”

Herd Health Troubles Potentially Related to Aluminium Grass Silage Content in Dairy Cows

In ruminants, the main documented clinical manifestation of aluminium (Al) intoxication is similar to grass tetany. In a 50 dairy cow Belgian herd, the farmer reported excessive uterine bleeding at calving and decreased milk production. Dairy cows received a mixed ration (MR) with high Al concentration (453 ppm/kg of dry matter (DM)). Various analyses were sampled from 10 sick cows and compared with 10 healthy cows (from another herd). Sick cows presented anaemia and marginal hypozincaemia and 6/10 showed subclinical ketosis. Their urine analysis revealed hypomagnesaemia and a high Al/creatinine ratio. It was advised to determine soil pH, add salts to the ration to chelate the Al and support cows with mineral supplements and propylene glycol. A visit was carried out 2 years later and highlighted an improvement in the situation, but all examined animals presented subclinical ketosis. Grass silage Al content remained high (700 ppm/kg DM), as did butyric acid concentration (11.22 g/kg DM). Al could be incriminated at different stages: micronutrient deficiencies, anaemia and negative energy balance. However, Al was probably not the only culprit. This case report is a concern for future years in these areas due to droughts, scarcity of forage and an increase in contaminated soil ingestion.

“…The dehydrated samples were then subjected to incineration in a muffle furnace (Nabertherm, Germany) with a temperature–time program of 450 °C–24 h, with a progressive rise in temperature of 50 °C per hour, until white ash was obtained [ 49 , 60 ]. At the end of the program, the samples were cooled inside the furnace to avoid contamination [ 26 ].…”

“…Specifically, because the liver is a fairly fatty tissue, in order to achieve its total digestion, prior to the incineration stage and after being weighed, a few drops (3–5 mL) of HNO 3 (65%) were added to the sample and were evaporated on a heating plate (Nabertherm, Germany) at 60 °C [ 60 ].…”

“…The quantification of trace elements and toxic metals was performed using atomic emission spectroscopy, because it is a reference technique for the determination of metals due to its high sensitivity and reproducibility in the results. The type of spectroscopy technique used was inductively coupled plasma optical emission spectrometry (ICP-OES) [ 60 ]. The ICP-OES equipment was the ICAP 6300 Duo Thermo Scientific (Waltham, MA, USA) model, with an automatic sampler (model CETAX ASX-520), and the instrumental conditions of the spectrometer were the following: approximate RF power (radio frequency) 1150 W, gas flow (nebulizer gas flow, make-up gas flow) 0.5 L/min, sample injection into the 50 rpm flow pump, 0 s stabilization time.…”

Assessment of Toxic Metals (Al, Cd, Pb) and Trace Elements (B, Ba, Co, Cr, Cu, Fe, Mn, Mo, Li, Zn, Ni, Sr, V) in the Common Kestrel (Falco tinnunculus) from the Canary Islands (Spain)

The monitoring of trace elements and toxic metals in apical predators of the trophic chain provides data on the degree of contamination in ecosystems. The common kestrel is one of the most interesting raptors in this respect in the Canary Islands; therefore, the study of the levels of trace elements and toxic metals in this species is of much scientific value. The content of trace elements and toxic metals (B, Ba, Co, Cr, Cu, Fe, Mn, Mo, Li, Zn, Ni, Sr, V, Al, Cd, Pb) was determined in the liver, muscle, and feathers of 200 specimens of common kestrel carcasses (Falco tinnunculus canariensis) from Tenerife. Cr (0.82 ± 2.62 mg/kg), Cu (11.82 ± 7.77 mg/kg), and Zn (198.47 ± 520.80 mg/kg) are the trace elements that stand out in the feather samples; this may be due to their affinity for the pigments that give them their coloring. Li was noteworthy in the liver samples (8.470 ± 5.702 mg/kg). Pb stood out in the feathers (4.353 ± 20.645 mg/kg) > muscle (0.148 ± 0.095 mg/kg) > liver (0.187 ± 0.133 mg/kg). The presence of metals in feathers correlates with recent exposure and reflects environmental contamination. When using raptor feathers as indicators of metal contamination, it is important to know what the levels of each metal signify. The analysis of the different tissues and organs of raptors, such as the common kestrel, provides valuable information on the degree of environmental contamination of the ecosystem in which it lives. Gender was not an influencing factor in this study.
