The use of biomimetic tools for water quality monitoring: passive samplers versus sentinel organisms
(Springer, 2021-03)
To evaluate the performance of artificial and biological integrative sampling strategies, dissolved concentrations of polychlorinated biphenyl (PCBs) and metals (Cu and Mn) were measured with passive sampler devices (PSD) ...
Surveillance for zoonotic vector-borne infections using sick dogs from southeastern Brazil
(Mary Ann Liebert, Inc., 2007-12-01)
For many vector-borne organisms, dogs can be used as sentinels to estimate the risk of human infection. The objective of this study was to use dogs as sentinels for multiple vector-borne organisms in order to evaluate the ...

Multitemporal spectral analysis for algae detection in an eutrophic lake using Sentinel 2 images
(Copernicus Publications, 2020-11)
Eutrophication is characterized by excessive plant and algal growth due to the increased of organic matter, carbon dioxide and nutrients in water body. Although eutrophication naturally occurs over centuries as lakes age, ...
Crassostrea gigas oysters as a shrimp farm bioindicator of white spot syndrome virus
(Diseases of aquatic organisms, 2012-04-26)
ABSTRACT: This study explored whether Crassostrea gigas oysters can be used as a bioindicator of white spot syndrome virus (WSSV) in shrimp farm water canals. Bioassays showed that C. gigas can accumulate WSSV in their ...
Coupling a bio-accumulator organism and MALDI-TOF MS: an early warning detection system for microcystins in water bodies
(2017)
Microcystins produced by freshwater cyanobacteria pose serious threats to human health and are a growing problem in drinking water supplies worldwide. Toxin detection and identification in water reservoirs when cyanobacterial ...
Multitemporal satellite imagery analysis for soil organic carbon assessment in an agricultural farm in southeastern Brazil
(2021-08-25)
Soil organic carbon (SOC) plays a crucial role for soil health. However, large datasets needed to accurately assess SOC at high resolution across scales are labor-intensive, time-consuming, and expensive. Ancillary geodata, ...
