Influencing factors and health risk assessment of microcystins in the Yongjiang river (China) by Monte Carlo simulation [PDF]

PeerJ, 2018
The Yongjiang river is a large, shallow, hyper-trophic, freshwater river in Guangxi, China. To investigate the presence of microcystin-RR, microcystin-LR, and microcystin-YR (MC-RR, MC-LR, and MC-YR) in the Yongjiang river and describe their correlation ...

Occurrence and Diversity of Cyanotoxins and Retinoid Compounds in Antarctic Microbial Mats: Evidence From James Ross Island

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
Occurrence and distribution of cyanotoxins and retinoids across different Antarctic ecosystems at James Ross Island. These ecosystems harbour diverse microbial communities dominated by autotrophic cyanobacteria and algae, which can produce hazardous compounds for animals.

First Detection of Microcystin-LR in the Amazon River at the Drinking Water Treatment Plant of the Municipality of Macapá, Brazil

Toxins, 2019
Human poisoning by microcystin has been recorded in many countries, including Brazil, where fatal cases have already occurred. The Amazon River is the main source of drinking water in municipalities such as Macapá, where there is no monitoring of ...

Drinking Water Quality Regulations: A Contrast Between Germany and Latin America

Environmental Quality Management, Volume 35, Issue 3, Spring 2026.
ABSTRACT This article investigates the differences among drinking water quality standards adopted in Latin American countries, Mexico, Cuba, and the European Union, considering the growing challenge of ensuring safe drinking water in a context marked by environmental pressures, climate change, and the occurrence of emerging contaminants. The study aims

Impacts of microcystin, a cyanobacterial toxin, on laboratory rodents in vivo

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2008
Cyanobacterial water blooms became a global problem/issue because beside a dramatic deterioration of water quality parameters they also produce cyanobacterial toxins being harmful for animals and humans.

Mitochondria a key role in microcystin‐LR kidney intoxication [PDF]

Journal of Applied Toxicology, 2007
AbstractMicrocystins (MCs) are a group of closely related cyclic heptapeptides produced by a variety of common cyanobacteria. These toxins have been implicated in both human and livestock mortality. Microcystin‐LR could affect renal physiology by altering vascular, glomerular and urinary parameters, indicating that MC‐LR could act directly on the ...

Estimating Operational Costs of Activated Carbon for Water Treatment Plants by Predicting the Rise of Harmful Algal Blooms Under Climate Change in Korea Using Machine Learning

Water Environment Research, Volume 98, Issue 3, March 2026.
This study investigated future operational costs in water treatment (WT) plants. Random forest modeling projected 3–5 times more abundant cyanobacteria by 2100 due to climate change. Increased microcystins demanded substantially more activated carbon and, as a result, WT costs could rise to $6–22/household/month.

Реконструкція просторової структури комплексів рослинних протеїнфосфатаз типу 1, 2а, 4 з мікроцистином-LR

Фактори експериментальної еволюції організмів, 2017
Aim. The major toxicity of Microcystin-LR (MCLR) has been ascribed to its potent ability to inhibit serine/threonine-specific protein phosphatase 1 (PP1) and protein phosphatase 2A (PP2A).

Teleosts as Models for Epigenetic Inheritance

Molecular Ecology, Volume 35, Issue 5, March 2026.
ABSTRACT Teleost fish exhibit a striking divergence from mammals in how they regulate their epigenome. Unlike mammals, they do not undergo the extensive DNA methylation erasure and resetting events that occur during early embryogenesis, germline specification, and spermatogenesis.

Probiotic Protects Kidneys Exposed to Microcystin-LR

Translation
Cyanobacterial Harmful Algal Blooms (CyanoHABs) occur when colonies of photosynthetic bacteria called cyanobacteria grow out of control, usually in warm, nutrient-rich, slow-moving waters.
