“…This technique allows to both analyze a very large number of elements (theoretically almost 70 natural elements of the Periodic Table; more realistically about 40 elements) with very good limits of detection (LODs), sensitivity and accuracy [16][17][18][19][20][21][22][23][24][25][26][27][28][29]. About the precision and accuracy of measurements performed on the standard involved in this study, all the found data for the standards are in agreement with the certified values.…”

Background: The commercial obsidian trade played an important role during Neolithic period. Its characteristics favoured the exchange network. In this way the Mediterranean area was fundamental. The availability of significant numbers of obsidian samples has allowed to improve the knowledge about the trade and commercial routes. Obsidian samples from the Mediterranean (Aegean, Flegrean, North Latium, Sicily, Sardinia) and Near East (Anatolia) areas were directly collected on the sites and considered as reference. Almost 30 elements were analyzed by Instrumental Neutron Activation Analysis (INAA).

“…This is not entirely unexpected because, although microalgae may contain certain elements of interest for nutrition, the inorganic elemental composition (ash) of microalgae (excluding diatoms) is generally much lower (4-20 %) than macroalgae (22-64 %) (McDermid and Stuercke 2003;Volkman and Brown 2006). We could only find two reports that provide data on the elemental content in algal biomass (Campanella et al 1998;Volkman and Brown 2006). Although useful for comparison, the data did not include certain elements and was limited to species which were not part of this study.…”

Microalgae contained low to moderate ash (5-17 %), moderate to high carbohydrate (18-46 %), crude protein (18-46 %), high crude lipid (12-48 %), and energy (19-27 MJ kg −1 ). Characteristic of microalgae, non-essential amino acids (AAs), aspartic and glutamic acids, were predominant (20-30 % of protein; 8-12 % of dry weight). Microalgae had favorable essential AA profiles with high essential amino acid (EAA) indices (0.9-1.2). Expressed as gE A A1 0 0gp r o t e i n −1 , Porphyridium aerugineum was rich in leucine (11.9), lysine (8.0), arginine (8.6), and tryptophan (3.3); Nannochloropsis granulata (A) in leucine (11.0), lysine (8.5), and tryptophan (2.8); Tetraselmis chuii and Botryococcus braunii in arginine (9.4 and 20.5, respectively); and Phaeodactylum tricornutum in lysine (6.4) and tryptophan (2.6). Mineral compositions (%) were calcium (0.1-3.0), magnesium (0.3-0.7), phosphorous (0.7-1.5), potassium (0.7-2.4), sodium (0.8-2.7), and sulfur (0.4-1.4), and trace element compositions (mg kg −1 )we reco pp er(1 8 -102), iron (1,395-11,101), manganese (45-454), selenium (0-0.5), and zinc (28-64). Microalgae contained low TPC (6-13 mg gallic acid equivalents (GAE) g −1 DW), except T. chuii (20 mg GAE g −1 DW). IVPD was high (>90 %) for B. braunii (A), P. aerugineum, and lipid-extracted N. granulata (B); mid-range (80-89 %) for P. tricornutum, N. granulata (A), B. braunii (B), Neochloris oleoabundans, T. chuii, and whole N. granulata (B); and lower (<80 %) for Acutodesmus dimorphus.M i c r o a l g a ls p e c i e sP. tricornutum, B. braunii, N. granulata,a n dT. chuii had high protein (40-52 %), IVPD (82-97 %), and digestible protein (35-50 %), comparable to plant proteins used in animal feeds and aquaculture.

Metal binding by algae has enormous potential for environmental bioremediation targeting towards detoxification of water bodies. The present work reports the use of live and dead Spirulina sp. for sorption of metals like Cr(3+), Ni(2+), Cu(2+), and Cr(6+) in form of Cr(2)O(7)(2-). Preliminary investigation shows that this biomass takes up substantial amount of metal ions indicated above. IR spectroscopic study, kinetics models, Langmuir and Freundlich adsorption isotherms, SEM analysis, and fluorescence microscopic study of Spirulina sp. and the Spirulina sp. treated with different metal ions have been employed to understand the sorption mechanism. It is hoped that live Spirulina sp. will be a strong candidate for management of industrial wastewater.
