Evaluation of the occurrence and fate of pesticides in a typical Mediterranean delta ecosystem (EBRO RIVER delta) and risk assessment for aquatic organisms
(Elsevier, 2020-10-14)
Delta ecosystems are areas of high ecologic and economic values, where wildlife commonly shares the territory with intensive agricultural activities, particularly, rice cultivation and seafood production. ...
Addressing the analytical challenges for the detection of ciguatoxins using an electrochemical biosensor
(American Chemical Society, 2020-03-05)
The importance of ciguatoxins (CTXs) in seafood safety and their emerging occurrence in locations far away from tropical areas highlight the need for simple and low-cost methods for the sensitive and ...
A fast magnetic bead-based colorimetric immunoassay for the detection of tetrodotoxins in shellfish
(Elsevier, 2020-04-05)
Tetrodotoxin (TTX) is a potent neurotoxin responsible for many food poisoning incidents and some fatalities. Although mainly associated with the consumption of pufferfish, in recent years, TTX has been ...
A polyphasic approach to the study of the genus Nitzschia (Bacillariophyta): three new planktonic species from the Adriatic Sea
(Wiley, 2020-10-21)
The paraphyletic diatom genus Nitzschia comprises over 1000 morphologically distinct pennate taxa, known from the benthos and plankton of freshwater, brackish and marine environments. The principal ...
Prey size and species preferences in the invasive blue crab, Callinectes sapidus: Potential effects in marine and freshwater ecosystems
(Elsevier, 2020-08-29)
The blue crab, Callinectes sapidus is an invasive species in the Mediterranean region. In Ebro Delta bays, it poses an important risk for the cultivation of Mediterranean mussel (Mytillus galloprovincialis) ...
Rapid detection of ciguatoxins in Gambierdiscus and Fukuyoa with immunosensing tools
(Elsevier, 2020-08-05)
Consumption of seafood contaminated with ciguatoxins (CTXs) leads to a foodborne disease known as ciguatera. Primary producers of CTXs are epibenthic dinoflagellates of the genera Gambierdiscus and ...
The role of rice fields and constructed wetlands as a source and a sink of pesticides and contaminants of emerging concern: Full-scale evaluation
(Elsevier, 2020-07-17)
Urban, industrial, and agricultural development in river basins has resulted in the pollution of estuarine and coastal ecosystems with a great amount of organic microcontaminants (OMCs) such as pesticides ...
Presence of CTXs in moray eels and dusky groupers in the marine environment of the Canary Islandsds
(Elsevier, 2020-01-31)
Local population frequently consumes moray eels and dusky groupers from the Canary Islands. These species are top predators and the interactions between them include predation but also, in some cases, ...
Combining an effect-based methodology with chemical analysis for antibiotics determination in wastewater and receiving freshwater and marine environment
(Elsevier, 2020-12-15)
Two different methodologies were combined to evaluate the risks that antibiotics can pose in the environment; i) an effect-based methodology based on microbial growth inhibition and ii) an analytical ...
Evaluation and sensitivity analysis of diatom DNA metabarcoding for WFD bioassessment of Mediterranean rivers
(Elsevier, 2020-04-04)
Our study of 164 diatom samples from Catalonia (NE Spain) is the first to evaluate the applicability of DNA metabarcoding, based on high throughput sequencing (HTS) using a 312-bp rbcL marker, for ...
