  1. 1. Zooplankton response to cyanotoxins

    Författare :Susanne Gustafsson; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Naturvetenskap; Natural science; cyanotoxins; maternal effects; algal toxins; zooplankton; tolerance; cyanobacteria;

    Sammanfattning : Mass development of cyanobacteria (blue-green algae) is common in many lakes and coastal waters worldwide as a result of an increased nutrient loading. These blooms of cyanobacteria are undesirable for several reasons; thick mats of algae and unpleasant odour reduces the recreational values, bad taste reduces the quality of drinking water and the potent toxins produced by some species of cyanobacteria endanger human health.

  2. 2. Managing Eutrophic Waters in Artificial Recharge Plants : Cyanotoxin risk in Swedish freshwaters

    Författare :Jing Li; Avdelningen för Teknisk vattenresurslära; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Drinking water; cyanobacterial blooms; cyanotoxins; nutrients; total phosphorus; DIN TP; quick test kit;

    Sammanfattning : In the last decades, the frequency and intensity of cyanobacterial blooms have been of increasing concern. They have become a direct threat to the drinking water supply by clogging filters, bringing odour and unpleasant taste to the treated water and worst of all, causing elevated cyanotoxins, which can be difficult to remove, yet lead to severe health issues.

  3. 3. From genes to blooms : Diversity in microcystin phenotypes and mcy biosynthesis genes in the cyanobacterium Microcystis

    Författare :Emma Johansson; Enhet akvatisk ekologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; limnologi; algblomning; cyanobakterier; cyanotoxiner; limnology; cyanobacterial blooms; cyanotoxins;

    Sammanfattning : Cyanobacterial blooms are increasing in occurrence and frequency world-wide, mainly due to eutrophication and increased water temperatures. In freshwater, Microcystis is one of the most common bloom-forming genera, renowned for producing the toxin microcystin which is harmful to humans and other mammals. LÄS MER

  4. 4. Biosensor-based Methods for Detection of Microcystins as Early Warning Systems

    Författare :Lesedi Lebogang; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microcystins; Drinking water; Adda-specific monoclonal antibodies; Biosensors; Capacitive; Amperometric; Flow-ELISA; Microcontact imprinting;

    Sammanfattning : Cyanobacteria blooms are a water menace since they produce potent toxins that have been implicated in poisonings and deaths of humans and animals after consumption or contact with cyanotoxin-contaminated water. Of particular concern are cyanotoxins called microcystins, which are hepatotoxic cyclic peptides known to promote development of liver tumors in humans and animals. LÄS MER
