Author:Oberholster, Paul J; Hill, Liesl; Jappie, S; Truter, JC; Botha, ADate:Sep 2015Although bioassay approaches are useful for identifying chemicals of potential concern, they provide little understanding of the mechanisms of chemical toxicity. Without this understanding, it is difficult to address some of the key challenges ...Read more
Author:Oberholster, Paul J; Mthethwa, BLS; Botha, AMDate:Sep 2009Due to the lack of toxin standards and resource limitations for wide scale use of analytical methods for e.g. high-performance liquid chromatography (HPLC) and enzyme-linked immunosorbent assay (ELISA) in cyanobacterial toxin monitoring, it ...Read more
Author:Omotola, EO; Genthe, B; Ndlela, Luyanda L; Olatunji, OSDate:Nov 2023Environmental effects of active pharmaceutical compounds (APCs) in the environment are not well characterized, hence the need for comprehensive evaluation. This study employed three bioassays using three organisms, namely, Allium cepa, Daphnia ...Read more
Author:Omotola, EO; Genthe, Bettina; Ndlela, Luyanda L; Olatunji, SODate:Jun 2023Residues of pharmaceutical compounds (PCs) are among the groups of contaminants of emerging concerns that have been reportedly detected in the aquatic environment. These compounds are widely distributed in diverse water bodies, thus, necessitating ...Read more
Author:Dellamatrice, PM; Monteiro, RTR; Blaise, C; Slabbert, JL; Gagne, JL; Alleau, SDate:Aug 2006We (the authors) examined the possibility of adapting the LuminoTox, a recently-commercialised bioanalytical testing procedure initially developed for aqueous samples, to assess the toxic potential of sediments. A significant correlation was ...Read more
