TL;DR: In this article, the authors studied the distribution and accumulation of heavy metals in Guanabara Bay, Brazil, and made an attempt to balance removal to the sediments and outputs from the bay.

TL;DR: The concentration of iodate and iodide were independently determined in seawater samples from Guanabara Bay (Rio de Janeiro, Brazil) taken at depths from 0.15 to 5 m (which was almost the bottom), at various times of day and in three different seasons as discussed by the authors.

TL;DR: In this article, an evaluation of the effectiveness of the ocean's biological pump in driving the deep-sea excess CO2 from the atmosphere is made based on sediment-trap data available in the literature and on estimates of present and future inputs of anthropogenic nitrogen and phosphorous.

TL;DR: In this article, the horizontal distribution of zinc in surface waters from Guanabara Bay has been studied by use of optimized voltammetric techniques and ultraclean working procedures, and the nonlinearity observed between the peak current for zinc and the electrolysis time, as well as the appearance of a peak at -1.16 V, are discussed.

TL;DR: A statistical analysis of these plots shows that the variation of ring widths in time is best represented by an exponential function of the formΔrn(t) =Δ rn0 +taebt (n = 40; 80), which turns out to be identical with the 2,700 years average of European oak trees, as found by Hollstein (1979) in his dendrochronological work.
