The Cananéia-Iguape estuarine–lagoon complex (São Paulo state, Brazil) is a natural laboratory to study metal binding by humic substances (HS) in subtropical settings. This transitional environment evolving into freshwater due water input from the Ribeira River, funneled through Valo Grande Canal (Iguape). Past mining activities River basin and maritime traffic are suspected be potential sources of trace metals system. In this study, contents Free Humic Acids (FHA), Bound (BHA), Fulvic (FA)...
Sewage introduction into rivers has altered the physical and chemical properties of waters also microbial metabolism. This study aimed to evaluate Escherichia coli nutrient concentrations in Maratuã Crumaú (Santos Estuary, Brazil) during two periods with distinct magnitudes freshwater runoff, verifying possible relation abiotic changes Water sampling was performed October/2012 (dry season) January/2013 (rainy at points river (upstream downstream zone) one (downstream zone). The water...
THE ESTUARINE ENVIRONMENT AND pH VARIATION: NATURAL LIMTS EXPERIMENTAL OBSERVATION OF ACIDIFICATION EFFECT ON PHOSPHORUS BIOAVAILABILITY. This study shows the variation of in Cananéia-Iguape Estuarine-Lagoon Complex (CIELC). Data from 3 years (2019, 2021, 2022) were obtained 17 points presenting following ranges: temperature (14.88-27.05 ºC), (7.16-8.40) and DIP (0.20-11.28 µmol L-1) along a saline gradient (0.05-32.09) under different hydrodynamics, biogeochemical processes anthropogenic...
Over the last decades, regional climate changes, erosion, and heightened agricultural runoffs have increased nutrient particle input in rivers, unbalancing biogeochemical cycle of this suspended material along estuaries. In context, fluxes euphotic zone, a very productive layer important to maintain food chain estuarine preservation, require better understanding. This study aims evaluate sedimentation photic zone Cananéia-Iguape Estuarine-Lagoon Complex (CIELC), considering sectors under...
Estuaries are important features for global biogeochemical understanding, due to their highly coupled interaction between sediment and water. In those places, the land-sea transect sometimes has a gradient of physical chemical characteristics, influencing availability nutrients consequently primary production. This study aimed observe benthic aerobic respiration sediment-water nutrient fluxes in freshwater marine Cananéia-Iguape Estuarine-Lagoon Complex (CIELC) on southeastern Brazilian...
Este estudo visou avaliar sazonalmente e espacialmente as principais formas de nitrogênio inorgânico dissolvido (NID) matéria orgânica (MO) nas águas superficiais dos dois maiores rios da Ilha Santo Amaro, o Maratuã Crumaú. Estes apresentam características físicas similares, porém com diferentes níveis interferências antropogênicas. Foi definida uma estação oceanográfica na jusante cada rio, terceira a montante do Neste local, os baixos valores oxigênio (OD) pH em meio elevadas concentrações...
