Aquatic Humic Substances: Relationship Between Origin and Complexing Capacity
(Springer, 2018-05-01)
Aiming to determine the relationship between source and complexing capacity, humic substances obtained from three sites (Sorocaba and Itapanhau Brasilian rivers, and Xochimilco Lake in Mexico) were studied. Copper, manganese, ...
Toxicity assessment of arsenic and cobalt in the presence of aquatic humic substances of different molecular sizes
(2017-05-01)
The release of contaminants in aquatic ecosystems can be influenced by humic acids. In this study, toxicity tests using environmentally relevant concentrations of arsenic and cobalt were conducted both in the presence and ...
Toxicity assessment of arsenic and cobalt in the presence of aquatic humic substances of different molecular sizes
(Elsevier B.V., 2017-05-01)

Atrazine interaction with tropical humic substances by Enzyme Linked Immunosorbent Assay
(E D P Sciences, 1998-04-01)
Enzyme-Linked Immunosorbent Assay (ELISA) has been evaluated by analyzing rich-humic water samples from tropical rivers. The samples were spiked with atrazine at ppb level Different pHs (4 to 9) and humic concentrations ...

(2012-08-01)
The northwest region of São Paulo State is a typical agricultural region with crops of sugarcane and oranges predominating, being chromium ions of environmental interest. Studies of the role of aquatic humic substances ...
Influence of Seasonality on the Interaction of Mercury with Aquatic Humic Substances Extracted from the Middle Negro River Basin (Amazon)
(Soc Brasileira Quimica, 2012-09-01)
High mercury concentrations in different environmental matrices in the Amazon have been attributed to mining activities. However, high concentrations of mercury are also present in the soil and water in places like in the ...
