摘要: Abstract The paper presents the metal pollution assessment of Jacarepagua basin rivers and lagoons based on statistical analysis concentration in bottom sediments. It is demonstrated that Pavuna Fundo Creeks are main sources anthropogenically introduced metals to lagoons. Due weak process water circulation contamination restricted discharge areas both rivers. Metal river sediments appears be highly dependent rainfall events thus a seasonal (wet dry seasons) variation their can proposed. examination lognormal distribution plots indicates values, related curve inflexion(s), operationally used as thresholds between polluted unpolluted areas. These values were; 0.92 μg g‐1 for Cd, 165 (μg Zn, 15 Cr 26 Ni. Factor was examine aquatic environment. suggested t...
