Tin in Organisms and Water in the Gulf of Naples

Abstract

THERE are few reported measurements of the concentration of tin in seawater or the tissues of marine organisms. Noddack and Noddack¹ gave a value of 3 µg of Sn/l. for water from the Gullmarfjord, Sweden, and Shimizu and Ogata² reported a concentration of 1.8 µg/l, for water from the Japan coast. Hamaguchi et al.³, using neutron activation analysis, found between 0.30 and 1.22 µg/l. (mean 0.81 µg/l.) in samples from the north-west Pacific. The most reliable information about the occurrence of tin in organisms was provided by Black and Mitchell⁴ for marine algae which contained 0.03–3.8 µg of Sn/g dry weight, and by Hamaguchi et al.³, who found 0.7–2.9 µg/g dry weight in three animal species from Tokyo Bay.
