Picoplankton structure in clear and turbid eutrophic shallow lakes: A seasonal study
(Elsevier Gmbh, 2011-09)
The relative abundance of the different picoplankton components (eukaryotic picophytoplankton (Peuk), picocyanobacteria (Pcy) and bacterioplankton), and their relationships with the lake conditions were studied in three ...
Água de abastecimento com elevada turbidez: eletrocoagulação/flotação como pré-tratamento em estações de tratamento de água
(Universidade Federal de Santa MariaBrasilEngenharia CivilUFSMPrograma de Pós-Graduação em Engenharia CivilCentro de Tecnologia, 2018-08-17)
Freshwater sources, surface (rivers, lakes) or groundwater, are generally used as resources for water supply. In order to the water to be distributed, treatments that aim at its ―safety‖ regarding aesthetic qualities, ...
Water turbidity-induced alterations in coloration and courtship behavior of male guppies (Poecilia reticulata)
(Springer, 2021-04-21)
Water turbidity deteriorates visibility and thereby may change the physiology and behavior of aquatic animals that rely on vision. In the guppy fish (Poecilia reticulata), a key element in the mating behavior and reproductive ...
A single algorithm to retrieve turbidity from remotely-sensed data in all coastal and estuarine waters
(Elsevier Science Inc, 2015-01)
Ocean color remote sensing has been shown to be a useful tool to map turbidity (T) and suspended particulate matter (SPM) concentration in turbid coastal waters. Different algorithms to retrieve T and/or SPM from water ...
Relationships between fish species abundances and water transparency in hypertrophic turbid waters of temperate shallow lakes
(Wiley Vch Verlag, 2010-05)
We explored the relationships between Secchi disc depth and the abundance of fish species in very shallow, hypertrophic, turbid waters of Pampa Plain lakes, Argentine. We tested whether the abundance of any of the species ...
Glyphosate input modifies microbial community structure in clear and turbid freshwater systems
(Springer Heidelberg, 2016-03)
Since it was commercially introduced in 1974, glyphosate has been one of the most commonly used herbicides in agriculture worldwide, and there is growing concern about its adverse effects on the environment. Assuming that ...
COVID-19 and surface water quality: Improved lake water quality during the lockdown
Human life comes to a standstill as many countries shut themselves off from the work due to the novel coronavirus disease pandemic (COVID-19) that hit the world severely in the first quarter of 2020. All types of ...
Moringa oleifera seed as a natural coagulant to treat low-turbidity water by in-line filtrationSemente de moringa oleifera como coagulante natural para tratar águas de baixa turbidez via filtração direta em linha
(2019-01-01)
This study evaluated the use of Moringa oleifera (MO) seed as a natural coagulant for the removal of turbidity and apparent color in the water treatment with low initial turbidity through the in-line filtration technique. ...
Qualidade da água de abastecimento público do município de Jaboticabal, SP
(2016-07-01)
The public‑supply water can be a vehicle of disease and harm to human health, therefore, efficient treatment and constant evaluation of its quality is required. The present study aimed to evaluate the population dynamics ...
Monitoring Turbid Plume Behavior from Landsat Imagery
(Springer, 2014-08)
A simple model based on available Landsat imagery data was used in order to characterize the dynamics of a rainstorm-induced turbid plume into a semi-arid, medium-sized reservoir. Additionally, a set of empirical expressions ...
