Sediment quality in a metal-contaminated tropical bay assessed with a multiple lines of evidence approach
(Elsevier B.V., 2017-09-01)
A sediment quality assessment was performed near to the main industrial source of metal contamination in Sepetiba Bay, Brazil, which represents one of the worst cases of trace metal contamination reported for coastal areas. ...
Bioremediation potential of new cadmium, chromium, and nickel-resistant bacteria isolated from tropical agricultural soil
(2020-11-01)
Soil management using fertilizers can modify soil chemical, biochemical and biological properties, including the concentration of trace-elements as cadmium (Cd), chromium (Cd) and nickel (Ni). Bacterial isolates from Cd, ...
Metals in superficial sediments of a cascade multisystem reservoir: contamination and potential ecological risk
(2017-11-01)
Cascade multisystem reservoirs are extremely complex ecosystems that require studies to improve understanding of their dynamics and functioning, including the effects of contamination with metals. In this work, superficial ...
Plant growth-promoting rhizobacteria effect on maize growth and microbial biomass in a chromium-contaminated soil
(Inst Agronomico, 2021-01-01)
Chromium contamination in soils affects plant growth and this metal can accumulate in plants tissues. In addition, Cr can affect soil microbial biomass and activity. On the other hand, plant growth-promoting rhizobacteria ...
Effects of metal contamination in situ on osmoregulation and oxygen consumption in the mudflat fiddler crab Uca rapax (Ocypodidae, Brachyura)
(Elsevier B.V., 2016-07-01)
The contamination of estuaries by metals can impose additional stresses on estuarine species, which may exhibit a limited capability to adjust their regulatory processes and maintain physiological homeostasis. The mudflat ...
Effects of metals on activity and community of sulfate-reducing bacterial enrichments and the discovery of a new heavy metal-resistant SRB from Santos Port sediment (São Paulo, Brazil)
(2022-01-01)
Sulfate-reducing bacteria (SRB) can be used to remove metals from wastewater, sewage, and contaminated areas. However, metals can be toxic to this group of bacteria. Sediments from port areas present abundance of SRB and ...
