Diatom teratologies as biomarkers of contamination: are all deformities ecologically meaningful?
(Elsevier, 2017)Contaminant-related stress on aquatic biota is difficult to assess when lethal impacts are not observed. Diatoms, by displaying deformities (teratologies) in their valves, have the potential to reflect sub-lethal responses ... -
Ecotoxicological assessment of chemical fumigants utilising an earthworm (Eisenia andrei) bioassay and soil microbial communities
(Springer, 2017)Fumigation is an important crop protection practice employed to control soil pathogens and diseases. Metham sodium and cadusafos are two commonly used soil fumigants for this purpose. However, little information is available ... -
Is the role of circulating DNA as a biomarker of cancer being prematurely overrated?
(Elsevier, 2010)Background Circulating DNA is utilized widely as a genetic biomarker in a variety of pathological conditions, mainly in cancerous conditions. Quantification of circulating DNA and identifying the frequencies of a variety ... -
Parasite responses to pollution: what we know and where we go in ‘ Environmental Parasitology ’
(BioMed Central, 2017)Environmental parasitology deals with the interactions between parasites and pollutants in the environment. Their sensitivity to pollutants and environmental disturbances makes many parasite taxa useful indicators of ... -
The role of fish helminth parasites in monitoring metal pollution in aquatic ecosystems: a case study in the world's most productive platinum mining region
(Springer, 2020)Due to the increasing consumption of platinum (Pt), especially in automobile exhaust catalysts, environmental concentrations of Pt are of emerging concern worldwide. Limited information exists on environmental concentrations, ... -
Sequence analysis of cell-free DNA derived from cultured human bone osteosarcoma (143B) cells
(Sage, 2018)The true importance of cell-free DNA in human biology, together with the potential scale of its clinical utility, is tarnished by a lack of understanding of its composition and origin. In investigating the cell-free DNA ... -
Utilizing an earthworm bioassay (Eisenia andrei) to assess a South African soil screening value with regards to effects from a copper manufacturing industry
(Springer, 2014)Metal contamination of soil due to industrialization has become an increasingly important problem in South Africa. This study aimed to investigate the potential impact of a copper (CuSO4·5H2O) production company on the ...
