Siyanobakterilerin
aşırı çoğalmaları sıklığı giderek artan ve tüm su kaynaklarını tehdit eden önemli
bir sorundur. Su kütlelerinde organik kirlenme sonucu oluşan ötrofikasyon göl
ve baraj göllerinin su kalitesinin bozulmasına ve siyanobakteriyel artışların
oluşumuna ortam hazırlamaktadır. İnsanlarda çeşitli hastalıklara, kuş ve sucul
canlılarda ölümlere sebep olan toksin üreticisi 40 farklı siyanobakteri türü
bilinmektedir. Bu toksinler etkilerine göre hepatotoksin, nörotoksin ve
dermatotoksinler olarak ayrılmaktadır. Bu derlemede, siyanobakterilerin aşırı
artışları ve içsularda oluşturduğu riskler tartışılacaktır.

Cyanobacterial blooms are increasing frequency and threatening water
sources worldwide. Eutrophication caused by organic pollution in water bodies provides
an environment for the deterioration of water quality and the formation of cyanobacterial
increases in lakes and reservoirs. 40 species of cyanobacteria are known as
producers of some toxins responsible for a wide array of health problems,
dangerous for aquatic organisms and responsible for bird kills. These toxins
are divided as hepatotoxin, neurotoxin and dermatotoxins according to their
effects. In this review, cyanobacterial blooms and risks in inland waters will
be discussed.
