Rapid chemiluminescence biosensing of microcystin-LR

Analytica Chimica Acta, 2009
A rapid immunoassay for sensitive detection of microcystin-LR using a portable chemiluminescence multichannel immunosensor (CL-MADAG) was developed. The sensor device is based on a capillary ELISA technique in combination with a miniaturized fluidics system and uses chemiluminescence as the detection principle.

Degradation of microcystin-LR by aquatic bacteria. [PDF]

, 2007
Microcystins are cyclic heptapeptide toxins produced by cyanobacteria. They are potentially a threat to human and domestic animals so are of worldwide interest. Microcystin-LR is stable in various environmental conditions. It is important to know the factors affecting microcystin degradation which can be utilised in water treatment methods.

Effects of microcystin-LR on mammalian ovaries

Reproductive Toxicology, 2023
The ovaries play critical roles in regulating oocyte maturation and sex steroid hormone production and thus are critical for female reproduction. Ovarian function relies on hormone receptors and signaling pathways, making the ovaries potential targets for environmental factors, such as microcystins (MCs).

Recent Advancement of Biosensor Technology for the Detection of Microcystin-LR

Bulletin of the Chemical Society of Japan, 2020
Microcystins are a class of toxins that are mainly produced by cyanobacteria and among them, microcystin-leucine arginine (microcystin-LR) is one of the most toxic and harmful of the fresh water toxins causing many accidents and threats to human health ...

Microcystin-LR and chemically degraded microcystin-LR electrochemical oxidation

The Analyst, 2012
Microcystins (MCs) are cyclic hepatotoxic heptapeptides produced by certain strains of freshwater cyanobacteria toxic for humans and animals. The electrochemical behaviour of microcystin-LR (MC-LR) at a glassy carbon electrode (GCE) was investigated using cyclic voltammetry (CV), square wave voltammetry (SWV) and differential pulse voltammetry (DPV ...

Electrochemical Degradation of Microcystin-LR

Journal of Environmental Science and Health, Part A, 2005
Microcystin-LR present in drinking water sources poses a considerable threat to human health. Conventional oxidation treatment systems, such as photocatalysis and ferrate oxidation, demonstrated the formation of by-products detectable in the treated microcystin-LR solution.

Microcystin-LR Adsorption by Activated Carbon

Journal of Colloid and Interface Science, 2001
We use a selection of wood-based and coconut-based activated carbons to investigate the factors controlling the removal of the hepatotoxin microcystin-LR (m-LR) from aqueous solutions. The wood carbons contain both micropores and mesopores. The coconut carbons contain micropores only.

The latest advances in the reproductive toxicity of microcystin-LR

Environmental Research, 2021
Microcystin-LR (MC-LR) is an emerging environmental pollutant produced by cyanobacteria that poses a threat to wild life and human health. In recent years, the reproductive toxicity of MC-LR has gained widespread attention, a large number of toxicological studies have filled the gaps in past research and more molecular mechanisms have been elucidated ...

Effects of microcystin-LR on mouse lungs

Toxicon, 2007
Toxic cyanobacteria blooms in drinking water supplies have been an increasing public health concern all over the world. Human populations can be exposed to microcystins, an important family of cyanotoxins, mainly by oral ingestion. However, inhalation from recreational water and hemodialysis can represent other routes.

Investigations into the biodegradation of microcystin-LR in wastewaters

Journal of Hazardous Materials, 2010
Microcystins are potent hepatotoxins that can be produced by cyanobacteria. These organisms can proliferate in wastewaters due to a number of factors including high concentrations of nutrients for growth. As treated wastewaters are now being considered as supplementary drinking water sources, in addition to their frequent use for irrigated agriculture,
