A previous pioneering study of freshwater bodies in Sri Lanka revealed the presence of toxic cyanobacteria in three out of four water bodies tested. It was therefore important to perform a more detailed investigation into the presence of cyanobacteri... Read More about Occurrence of toxigenic cyanobacterial blooms in freshwaters of Sri Lanka..

Geosmin (GSM) and 2-methylisoborneol (MIB) are semi-volatile compounds produced by cyanobacteria in surface waters. These compounds present problems to the drinking water industry and in aquaculture because they can taint water and fish producing an...

Processes influencing surface interaction and photocatalytic destruction of microcystins on titanium dioxide photocatalysts. (2002)
Journal Article

Journal of catalysis [online], 213(1), pages 109-113. Available from: https://doi.org/10.1016/S0021-9517(02)00049-0

Microcystins are a family of hepatotoxic peptides produced by freshwater cyanobacteria. Their occurrence in drinking water is of concern since chronic exposure to these toxins causes tumor promotion. It is therefore essential to establish a reliable... Read More about Processes influencing surface interaction and photocatalytic destruction of microcystins on titanium dioxide photocatalysts..

Mechanistic and toxicity studies of the photocatalytic oxidation of microcystin-LR. (2002)
Journal Article
LIU, I., LAWTON, L.A., CORNISH, B. and ROBERTSON, P., 2002. Mechanistic and toxicity studies of the photocatalytic oxidation of microcystin-LR. Journal of photochemistry and photobiology A: chemistry [online], 148(1-3), pages 349-354. Available from: https://doi.org/10.1016/S1010-6030(02)00062-X

Cyanobacterial toxins present in drinking water sources pose a considerable threat to human health. Conventional water treatment systems have proven unreliable for the removal of these toxins and hence new techniques have been investigated. Previous...

The destruction of the cyanobacterial toxin microcystin-LR by semiconductor photocatalysis. (2000)
Thesis
CORNISH, B.J.P.A. 2000. The destruction of the cyanobacterial toxin microcystin-LR by semiconductor photocatalysis. Robert Gordon University, PhD thesis.

In fresh waters where cyanobacteria (blue-green algae) flourish, dense growths known as blooms occur. Such blooms present a threat to human and animal health as many of these cyanobacteria produce toxins. One such group of toxins are the microcystins...

Physico-chemical treatment methods for the removal of microcystins (cyanobacterial hepatotoxins) from potable waters. (1999)
Journal Article
LAWTON, L.A. and ROBERTSON, P.K.J. 1999. Physico-chemical treatment methods for the removal of microcystins (cyanobacterial hepatotoxins) from potable waters. Chemical society reviews [online], 28(4), pages 217-224. Available from: https://doi.org/10.1039/A805416I

The incidence of cyanobacterial blooms in freshwaters, including drinking water reservoirs, has increased over the past few decades due to rising nutrient levels. Microcystins are hepatotoxins released from cyanobacteria and have been responsible for...

Purification, detection and biological effects of cyanobacterial toxins. (1999)
Thesis
MCELHINEY, J. 1999. Purification, detection and biological effects of cyanobacterial toxins. Robert Gordon University, PhD thesis.

Dense growths of cyanobacteria (blue-green algae), known as blooms, commonly occur in fresh and brackish waters throughout the world. Cyanobacterial blooms present a considerable threat to water quality as many species produce toxins. These toxins ha...
