Influence of sampling strategies on the monitoring of cyanobacteria in shallow lakes: Lessons from a case study in France

Sampling cyanobacteria in freshwater ecosystems is a crucial aspect ofmonitoring programs in both basic and applied research. Despite this, few papers have dealt with this aspect, and a high proportion of cyanobacteria monitoring programs are still based on monthly or twicemonthly water sampling, usually performed at a single location. In this study, we conducted high frequency spatial and temporal water sampling in a small eutrophic shallow lake that experiences cyanobacterial blooms every year. We demonstrate that the spatial and temporal aspects of the sampling strategy had a considerable impact on the findings of cyanobacteria monitoring in this lake.For more information about this study please send an e-mail to: info@microlan.nl

	Pilot Project Romania
For the production of drinking water various raw water sources are used: ground water or surface water. Ground water is usually “safe”, but insufficiently available. Drinking water companies use for this reason surface water from lakes or rivers. This is the case for the drinking water company Apavital in Iaşi, which uses not only ground water but also surface water from the rivers Prut and Moldova. A quick and reliable identification of high-impact contamination in river water is the ultimate goal of this project. The monitoring system, being a part of a sophisticated intake management framework, should ensure a reliable and safe drinking water supply in the agglomeration of Iaşi. The system must detect a contamination event in a time frame that allows the implementation of an effective response to reduce or avoid the adverse impacts that may result from the event.
For more information about this project take a look at our website www.toxcontrol.com or contact us at info@microlan.nl

SPE of heavy metals in water samples for sensitive continuous toxicity monitoring
Because the “Vibrio Fischeri” bacteria are not sensitive enough to measure low concentrations of heavy metals, we have investigated a possibility to concentrate heavy metals and use the endproduct in the iTOXcontrol biomonitor for an increased sensitivity towards the “Vibrio Fischeri” bacteria.
More information and the results of this study can be found at www.toxcontrol.com

EVALUATION OF AN AUTOMATED LUMINESCENT BACTERIA ASSAY FOR IN SITU AQUATIC TOXICITY DETERMINATION
Legislation related to the preservation of quality of water bodies is becoming more stringent both at national and international level. In the European context, the Water Framework Directive (WFD 2000/60/EU) is an example of the new attitude adopted (risk-based) in terms of environmental impacts. The WFD requires both a good chemical and biological status of water bodies; therefore new monitoring assays to detect changes in water quality on short notice are required. CETaqua and CRIT-UPC have investigated a new technology to perform bioluminescence inhibition assays, the TOXcontrol® Toxicity Monitoring System (microLAN BV), has been used to determine global toxicity (EC50, that is, Effective Concentration causing 50% inhibition) of selected compounds including pesticides, pharmaceuticals and surfactants commonly detected in European surface waters. This new technology is based on the measurement of Vibrio fischeri bioluminescence inhibition (ISO 11348). The main advantage of this equipment, compared to other laboratory assays based on luminescent bacteria, is its fully automation. The instrument can be operated online in a simple, rapid and reproducible way.
For more information about this study or a copy of the poster, please send an e-mail to : info@microlan.nl

Coming soon… Assessment of Equitox software for TOXmini
The TOXmini measures the response of the luminescent bacteria “Vibrio Fisheri” exposed to sample water. To calculate the amount of Equitox the EC50 has to be determined. We are developing a software tool for the automatic calculation and presentation of the amount of Equitox per waste water volume using the TOXmini (“Vibrio Fischeri”).
The software will be released the coming months, so keep an eye on our newsletter. Interested in the TOXmini and the Equitox software ? Ask for a demo !

	Test locations
microLAN is looking for test locations for the TOXmini and/or the iTOXcontrol.
In the past year microLAN has done a lot of development and improvement on our (online-) biomonitoring systems. At this moment we are looking for demo locations to place our systems to prove to you the enhanced features and extended usefulness that will help you controlling your process. The online iTOXcontrol helps to control your process by measuring the toxicity of the influent and/or the effluent at your biological treatment plant. The TOXmini on the other hand is a portable system for lab and field toxicity measurements in a wide variety of samples and applications.

RIVM report : “Toxic pressure in the Dutch delta measured with bioassays”

Measuring exclusively the effects of toxic substances in surface water can be used in addition to, or as an alternative for, traditional chemical techniques. Chemical monitoring has several shortcomings. It can never cover the large number of chemicals potentially present in surface waters, and combined effects of substances (synergistic, additive or antagonistic) are not included. The biomonitoring procedure consists of a method to extract and isolate the toxic fraction from surface water. Subsequently, the (acute) effect of toxic substances is determined by means of a battery of organisms from different trophic levels. Such an approach makes it feasible to interpret the data using a species sensitivity distribution to indicate the potentially negative influence of toxic substances on the ecological status. In the Netherlands, the experimental procedure for monitoring by means of bioassays has not been changed during the past decade and has been applied within the framework of a monitoring program carried out for the last ten years. The results offer an excellent opportunity to evaluate the trend in toxic pressure in Dutch freshwater water bodies.
