“…Similarly elevated concentrations have been discovered in blood cells of ascidians (vandocytes) with values up to 350 mM, approximately 10 7 -fold higher than the typical vanadium concentration in seawater (Kanda et al 1997). More typical values for vanadium in marine organisms range from less than 0.2 to approximately 8 µg/g, also in areas impacted by vanadiumcontaining oil spills (Sperling et al 2000;Al-Mohanna and Subrahmanyam 2001;Lavilla et al 2006;Fattorini et al 2008). Our results on the two Antarctic bivalves sampled in the same area of P. littoralis, and previous results on vanadium concentrations in organisms from Terra Nova Bay never reported values higher than 3 µg/g (Minganti et al 1998;Bargagli 2005;Grotti et al 2008).…”

The hyperaccumulation of toxic metals might represent a common antipredatory strategy for unpalatable branchial crowns of sabellid polychaetes, as recently hypothesized also for the high concentrations of arsenic in the Mediterranean Sabella spallanzanii. The evolution of such adaptation and the reasons behind the possibility for different species to accumulate different metals represent a stimulating field of investigation for future studies.

“…Digestion can also be carried out in an ultrasonic water bath using plastic screw-top bottles or polypropylene centrifuge tubes, which means that samples can be centrifuged instead of filtering [32,37]. Ultrasound-assisted digestion is safer than microwave digestion, because pressure and temperature are substantially lower in ultrasound technique [38].…”

A method of ultrasound-assisted digestion followed by inductively coupled plasma optical emission spectrometry (ICP-OES) used for the determination of toxic element concentrations (arsenic, barium, cobalt, copper, lead, nickel, strontium, vanadium and zinc) in ash samples was developed. All the measurements were performed in robust plasma conditions which were tested by measuring the Mg II 280.270 nm / Mg I 285.213 nm line intensity ratios. The highest line intensity ratios were observed when a nebulizer gas flow of 0.6 L min -1 , auxiliary gas flow of 0.2 L min -1 and plasma power of 1400 W were used for radially viewed plasma.The analysis of SRM 1633b showed that the ultrasound-assisted method developed is highly comparable with the microwave digestion method standardized by the United States Environmental Protection Agency (EPA-3052). The ultrasound-assisted digestion with a digestion solution of aqua regia and hydro fluoric acid (HF) resulted in recovery rates of over 81 %. One exception is arsenic which resulted in recoveries of about 60 % only; however, it could be digested with good recovery (> 90 %) using a digestion solution of 5 mL of water and 5 mL of aqua regia. The major advantage of the ultrasound-assisted digestion over microwave digestion is the high treatment rate (30 samples simultaneously with a sonication time of 18 min).

A method of ultrasound-assisted digestion followed by inductively coupled plasma optical emission spectrometry (ICP-OES) used for the determination of trace element (chromium, copper, lead, nickel, vanadium and zinc) concentrations in fly ash samples was developed.All the measurements were performed in robust plasma conditions. Ultrasound-assisted digestion procedures using digestion solutions of aqua regia and hydrofluoric acid (HF) resulted in recovery rates of over 80 % for all the analyte elements. Ultrasound-assisted twostep digestion with digestion solutions of 6 mL of HNO 3 (Step 1) and 3 mL of HNO 3 + 3 mL of HF (Step 2) resulted in recovery rates of over 92 % for all the analyte elements with one exception, chromium, which had a recovery of about 85 %. The analysis of SRM 1633bshowed that the two-step ultrasound-assisted digestion method developed resulted in chromium, copper, nickel and zinc concentrations higher than the microwave digestion method standardized by the United States Environmental Protection Agency (USEPA method 3052). This is the very first time when a digestion method using ultrasound resulted in higher efficiency than microwave (USEPA method 3052) for chromium and nickel in very hard to dissolve samples. The major advantages of the ultrasound-assisted digestion over microwave digestion is the high treatment rate (about 30 samples simultaneously with a sonication time of 18 min) and the possibility to use new sample vessels without a significant increase in costs.
