“…Our results show that the main elements were calcium, phosphorous and magnesium in the bones, similar to the study of Oudadesse et al (2004). The concentration of sodium and barium were also present in the large bones similarly to other findings (Klepinger 1984).…”

Amphibians, particularly frogs, are increasingly used as bioindicators of contaminant accumulation in pollution studies. Their use for field scientific purposes is limited because most frog species are endangered and protected in most countries; killing of specimens are not allowed. The aim of our study was to work out and assess a method by which the elemental contents of frog bones could be estimated effectively based on the toe bones. For this purpose, Rana esculenta L. individuals were collected from an urban pond in Debrecen city (Hungary). The following large bones were also analysed: skull, spinal, femur, tibia-fibula, tarsal bones, metatarsus, humerus and digits from front and hind limbs. In the bones, P, Ca, Mg, Mn, Na, S and Zn elements were measured.

“…Similar to an earlier study (Oudadesse et al 2004), our results showed Ca, P and Mg to be the main elements in the bones. Ca and P, the main components in hydroxyapatite, are known to be of at most importance (Janus et al 2008).…”

Amphibians, particularly frogs and toads, are increasingly used as bioindicators of contaminant accumulation in pollution studies. We developed an analytical technique to analyse their elemental contents based on a small amount of toe bone samples. This method is environment-friendly as, unlike traditional methods, it is not necessary to kill animals during sampling. Using this technique, we explored the effects of urbanization on the elemental contents of toe bones. Bufo bufo specimens were collected from an urban and two rural ponds. The ratios of Ca and P at the ponds were: 20.5% Ca and 14.6% P at the urban pond and 30.4% and 29.6% Ca, 22.4% and 21.7% P at the rural ponds, respectively. For the other elements, the following percentage ratios were found: 0.7% B, 0.3% Mg and 0.06% Zn at the urban pond and 1.1% and 0.4% B, 0.4% Mg and 0.05% Zn at the rural ponds, respectively. Canonical discriminant analysis indicated the separation of the urban and the rural ponds based on the elemental concentrations of toe bones. Significant differences were found between the concentrations of Ca, P, Mg, B and Zn at the urban and the rural ponds (p<0.05). Anthropogenic activity was found to have effects on the elemental contents of toe bones in the urbanized area. Our study also demonstrated that the developed method was appropriate for the elemental analysis of small samples to assess the effects of urbanization.

“…More pragmatic concerns include controlling carbonate precipitation during desalinization (Elliot 1969;Morse et al 1979;Omar et al 2009), geothermal energy production (Arnorsson 1979;Amjad 1987), and waste treatment (Reddy 1978). More recently, aragonite precipitation kinetics have been studied to estimate and manipulate the growth rate of biogenic skeletal tissues (e.g., otoliths: Romanek and Gauldie 1996; restorative and osseous surgeries: Oudadesse et al 2004) and to effectively control the growth forms of aragonite for coatings and fillers in various industrial applications Deng 2003, 2004).…”

Aragonite was synthesized inorganically using a seeded-growth technique to characterize precipitation kinetics for the heterogeneous growth of solid from dilute solutions (ionic strength: 0.05-0.07 mol l -1 ). The concentration of all aqueous constituents, including Ca (*5-15 mmol l -1 ), Na (*10-35 mmol l -1 ), Cl (*30-35 mmol l -1 ), and carbon (as total alkalinity: *10 to 17 meq l -1 ), was held constant by the addition of titrants that contained excess solute concentrations to balance the growth of solid phase during the precipitation reaction, and a CO 2 /N 2 gas mixture (0.009-0.178) was bubbled through each solution to facilitate mass exchange between gaseous and aqueous carbon species. Forty-three experiments were conducted at 10°(n = 13), 25°(n = 21), and 40°C (n = 9), over a range of average saturation states with respect to aragonite from 8.3 to 28.5, 2.9 to 19.6 and 2.0 to 12.2, and average precipitation rates from 10 2.8 to 10 3.8 , 10 2.3 to 10 4.0 , and 10 2.5 to 10 4.1 micromol m -2 h -1 , respectively. Reaction orders averaged 1.7 ± 0.10 at 10°, 1.7 ± 0.07 at 25°and 1.5 ± 0.06 at 40°, and they were independent of temperature while rate constants averaged 10 1.3 ± 0.12, 10 1.9 ± 0.06, and 10 2.6 ± 0.04 micromol m -2 h -1 , respectively, increasing one-half order of magnitude for each 15°C rise in temperature. From these data, an Arrhenius activation energy of 71.2 kJ mol -1 is calculated for the heterogeneous precipitation of aragonite. This value is comparable to a sole independent measurement of 80.7 kJ mol -1 reported for the solid-solution recrystallization of monohydrocalcite to aragonite (Munemoto and Fukushi in J Mineral Petrol Sci 103: 345-349, 2008).
