Análise química de sais de cobre fabricados entre 1877 e 1995

Samples of copper compounds covering all of the XXth century and the end of the XIXth century were submitted to classical and instrumental quantitative analysis. The amount of impurities greatly decreased with time, reaching a constant level since the 1960's. The gravimetric method was suitable for the determination of copper although other procedures also gave good or reasonable results. However, for metal contaminants, atomic absorption spectrometry was the best choice because of its lower detection limits, being able to determine several elements in the oldest samples. Ion chromatography detected several anions in copper salts manufactured before the 1950's. An increasing quality of raw materials and a better sensitivity of analytical methods led to quality improvement of copper compounds with time.

A new species of Neotropical freshwater stingray of the genus Potamotrygon Garman, 1877 from the Río Madrede Díos, Peru (Chondrichthyes: Potamotrygonidae)

Potamotrygon tatianae sp. nov., is described from Río Madre de Díos, Peru, upper Rio Madeira basin. The new species is distinguished from all congeners by a unique combination of characters, including its dorsal color pattern formed by a relatively slender, highly convoluted, beige to dark brown vermicular pattern, a single row of dorsal tail spines, and a relatively longer tail posterior to caudal stings. Potamotrygon tatianae sp. nov., occurs sympatrically with other species of Potamotrygon (P. falkneri, P. orbignyi and P. motoro). From the similar species P. falkneri, P. tatianae sp. nov., is further distinguished by the absence of circular, reniform, and oval spots, by its proportionally much longer tail, by having dorsal tail spines in one irregular row, and by features of the ventral lateral-line canal, dermal denticles and neurocranium. From P. orbignyi, the new species is distinct by lacking a reticulate pattern on dorsal disc and by the presence of two angular cartilages. From P. motoro, P. tatianae sp. nov., is further separated by the lack of ocelli formed by strong black concentric rings, by the more flattened aspect of its head and disc, and by having smaller and more numerous teeth. The discovery of a new species that so closely resembles a congeneric form in color pattern, a feature highly variable within the latter, highlights the importance of examining large series of individuals and of detailed morphological analyses in revealing the potentially highly cryptic nature of the diversity within the family.
