“…For a general algicidal function, a 5 or even 10 times higher concentration is needed than for a cyanocidal application, and use of such a higher concentration also requires special permission for lawful application, see Burson et al (2014) describing a successful termination of a harmful dinoflagellate bloom. This application, however, differs from the mild cyanocidal approach in damaging a wider range of life in the treated water body.…”

To help ban the use of general toxic algicides, research efforts are now directed towards the discovery of compounds that are specifically acting as cyanocides. Here, we review the past and look forward into the future, where the less desirable general algicides like copper sulphate, diuron or endothall may become replaced by compounds that show better specificity for cyanobacteria and are biodegradable or transform into non-toxic products after application. For a range of products, we review the activity, the mode of action, effectiveness, durability, toxicity towards non-target species, plus costs involved, and discuss the experience with and prospects for small water volume interventions up to the mitigation of entire lakes; we arrive at recommendations for a series of natural products and extracted organic compounds or derived synthetic homologues with promising cyanocidal properties, and briefly mention emerging nanoparticle applications. Finally, we detail on the recently introduced application of hydrogen peroxide for the selective killing of cyanobacteria in freshwater lakes.

“…A. ostenfeldii is historically seen as background bloomer (Cembella et al, 2000;John et al, 2003), however, dense A. ostenfeldii blooms have been reported recently in the Narragansett Bay and the New River Estuary in the U.S. east coast (Borkman et al, 2012;Tomas et al, 2012), the Baltic Sea coast of Finland (Hakanen et al, 2012), along the Adriatic coast of Italy (Ciminiello et al, 2006), and recently in a creek of the Oosterschelde estuary in the Southwest of The Netherlands (Burson et al, 2014). This Oosterschelde estuary is a shallow, macrotidal and mesotrophic estuary with large stocks of mussels, oysters, and cockles ( Fig.…”

“…Because of potential contamination of these shellfish with phytoplankton toxins, The Netherlands has a regular monitoring program for toxic compounds in shellfish, as well as for the occurrence of harmful algal species in the Oosterschelde estuary (van der Fels-Klerx et al, 2011). A recent dense A. ostenfeldii bloom in a creek discharging water into the Oosterschelde threatened the shellfish stocks, and was terminated by the addition of hydrogen peroxide (Burson et al, 2014). The bloom, however, recurred in 2013 and reached population densities of up to 4500 cells mL À1 (Fig.…”

Ecotoxicological assessment of flocculant modified soil for lake restoration using an integrated biotic toxicity index

a b s t r a c tFlocculant modified soils/clays are being increasingly studied as geo-engineering materials for lake restoration and harmful algal bloom control. However, the potential impacts of adding these materials in aquatic ecological systems remain unclear. This study investigated the potential effects of chitosan, cationic starch, chitosan modified soils (MS-C) and cationic starch modified soils (MS-S) on the aquatic organisms by using a bioassay battery. The toxicity potential of these four flocculants was quantitatively assessed using an integrated biotic toxicity index (BTI). The test system includes four aquatic species, namely Chlorella vulgaris, Daphnia magna, Cyprinus carpio and Limnodrilus hoffmeisteri, which represent four trophic levels in the freshwater ecosystem. Results showed that median effect concentrations (EC 50 ) of the MS-C and MS-S were 31e124 times higher than chitosan and cationic starch, respectively. D. magna was the most sensitive species to the four flocculants. Histological examination of C. carpio showed that significant pathological changes were found in gills. Different from chitosan and cationic starch, MS-C and MS-S significantly alleviated the acute toxicities of chitosan and cationic starch. The toxicity order of the four flocculants based on BTI were cationic starch > chitosan > MS-S > MS-C. The results suggested that BTI can be used as a quantitative and comparable indicator to assess biotic toxicity for aquatic geo-engineering materials. Chitosan or cationic starch modified soil/clay materials can be used at their optimal dosage without causing substantial adverse effects to the bioassay battery in aquatic ecosystem.
