Call for STSMs

Dear WaterTOP members,

We would like to invite you to submit proposals for 2021 Short Time Scientific Missions (STSMs) between September and October 2021 in the framework of the WaterTOP COST Action.

For those of you who are not familiar what an STSM is, here are some brief information:

  • Short Term Scientific Missions (STSM) are exchange visits aimed at supporting individual mobility, strengthening existing networks and fostering collaboration between Researchers. A STSM should specifically contribute to the scientific of the COST Action, whilst at the same time allowing those partaking in the missions to learn new techniques, gain access to specific data, instruments and / or methods not available in their own institutions / organisations. 
  • STSM applicants must be engaged in an official research programme as a PhD Student or postdoctoral fellow or can be employed by, or affiliated to, an Institution or legal entity which has within its remit a clear association with performing research. The institutions / organisations where applicants pursue their main strand of research are considered as Home institutions. The Host institution is the institution / organisation that will host the successful applicant.

You may find more information regarding the selection and reimbursement criteria in pages 32 and 33 of the “COST Vademecum” found at: https://www.cost.eu/uploads/2021/04/Vademecum-28-April-2021.pdf

The deadline for this call is the 30th of September 2021 and the accepted STSMs should be completed the latest by 30th of October 2021. All proposals will be reviewed by our STSM committee and the applicants will be notified as soon as there is a decision.

For those of you who wish to apply for an STSM please click on the link https://e-services.cost.eu/ and fill-in the online application under the ‘STSM’ tab of the WaterTOP COST Action.

The next STSM period is expected to start with an open call for STSM applications during October 2021, and will last until 31st December 2021.

Kind regards,

Dr. Popi Karaolia (STSMs Coordinator)

Dr. Latife Koker (STSM Committee)

WRF Webcast: Managing Intracellular Cyanotoxin Release During Oxidation Processes in Drinking Water Treatment Plants

Thu, Mar 21, 2019 3:00 PM EDT (9:00 PM EET), 1 hour 30 min

Utilities have been seeking guidance to effectively control cyanobacteria cells and eliminate cyanotoxins using holistic management and treatment strategies. Current guidance suggests that switching water sources or removing intact cells can minimize the risk of releasing intracellular (or cell-bound) cyanotoxins. Our presenters will discuss options to use when this operational flexibility is unavailable, including the deliberate release and treatment of intracellular cyanotoxins using oxidation processes. In addition, the incorporation of intracellular cyanotoxin release into the upcoming CyanoTOX Tool (Version 3) will be presented. The webcast will include information from the WRF Tailored Collaboration project, Release of Intracellular Cyanotoxins During Oxidation of Naturally Occurring and Lab Cultured Cyanobacteria (#4692), which highlights ways to improve available guidance to utilities regarding the release of intracellular cyanotoxins during oxidation of naturally occurring and lab-cultured cyanobacteria.

Presenters:
Eric Wert, PhD, PE, Project Manager, Water Quality Research and Development, Southern Nevada Water Authority
Craig Adams, PhD, PE, Oliver Parks Professor of Engineering, Department of Civil Engineering, Saint Louis University
Katie Greenstein, PhD, PE, Chemist, Des Moines Water Works
Eric Rosenfeldt, PhD, PE, Senior Principal Engineer, Hazen and Sawyer
Arash Zamyadi, PhD, Assistant Professor, Polytechnique Montreal, University of Montreal, Canada

The Oxford Word of the Year 2018 is… “toxic”.

The Oxford Word of the Year 2018 is… “toxic”.

From the article published by Oxford Dictionaries:

“Data show that, along with a 45% rise in the number of times it has been looked up on oxforddictionaries.com, over the last year the word toxic has been used in an array of contexts, both in its literal and more metaphorical senses.”

“One of the many environmental issues discussed this year has been the toxic algae disaster in Florida, US. Thanks to a central role in the state’s Senate mid-terms race, toxic algae garnered so much commentary that ‘algae’ featured as the ninth-most frequently seen toxic collocate for 2018.

Occurrence and diversity of cyanotoxins in Greek lakes

From the abstract of a recent paper published by Christophoridis et al. in Scientific Reports:

“Toxic cyanobacteria occur in Greek surface water bodies. However, studies on the occurrence of cyanotoxins (CTs) are often limited to mainly microcystins (MCs), with use of screening methods, such as ELISA, that are not conclusive of the chemical structure of the CT variants and can be subject to false positive results. A multi-lake survey in Greece (14 lakes) was conducted in water and biomass, targeted to a wide range of multi-class CTs including MCs, nodularin-R (NOD), cylindrospermopsin (CYN), anatoxin-a (ANA-a) and saxitoxins (STXs), using multi-class/variant LC-MS/MS analytical workflows, achieving sensitive detection, definitive identification and accurate quantitation. A wide variety of CTs (CYN, ANA-a, STX, neoSTX, dmMC-RR, MC-RR, MC-YR, MC-HtyR, dm3MC-LR, MC-LR, MC-HilR, MC-WR, MC-LA, MC-LY, MC-LW and MC-LF), were detected, with MCs being the most commonly occurring. In biomass, MC-RR was the most abundant toxin, reaching 754 ng mg−1 dw, followed by MC-LR (458 ng mg−1 dw). CYN and ANA-a were detected for the first time in the biomass of Greek lakes at low concentrations and STXs in lakes Trichonis, Vistonis and Petron. The abundance and diversity of CTs were also evaluated in relation to recreational health risks, in a case study with a proven history of MCs (Lake Kastoria).”

The study was funded by the project ARISTEIA: “CYANOWATER” coordinated by A. Hiskia (NCSR Demokritos) and it also acknowledges CYANOCOST.

Algal bloom kills 250,000 salmon in Canada

News reproduced from www.griegseafood.no.

“Grieg Seafood has experienced acute mortality at two of its BC locations in the Jervis Inlet following harmful algal blooms (HAB) in the area. Total mortality is estimated to 250,000 fish or approximately 1,000 tons. This represents some 50 percent of the total biomass from the two locations.

Grieg Seafood continuously works to improve biosecurity and all of Grieg Seafood’s sites perform algal monitoring by taking daily samples which are analyzed using advanced image analysis techniques. This allows for the identification of the species, prevalence and depth distribution of any algae present.

The HAB in Jervis consisted of Heterosigma, a species of microscopic algae that cause acute mortality in fish. Due to extraordinarily high concentration and spread throughout the entire water column, use of Aeration treatments or other protective measures could not prevent the incident.

Grieg Seafood has insurances covering such incidents, and estimated costs including individual share of insurance are limited to NOK 25 million. The costs will be charged the Q2 2018 results”.

New research links neonatal exposure to BMAA in a rat model with neurodegenerative diseases

A new paper published by Laura Louise Scott and Timothy Grant Downing of the Nelson Mandela University in South Africa, presents results about the selective toxicity of BMAA during neurogenesis in the rodent brain.  The authors have observed neuropathological symptoms typically associated with Alzheimer’s Disease, Parkinson’s Disease  and Amyotrophic Lateral Sclerosis following a single BMAA neonatal exposure. It is suggested that BMAA elicits its effect by altering dopamine and/or serotonin signaling in rats.
