Effects of microcystins-containing cyanobacteria from a temperate ecosystem on human lymphocytes culture and their potential for adverse human health effects

▸ We estimate of microcystins (MCs) role in environment and crude or purified extra. ▸ No clear relation between MCs in extracts and lymphocytes mortality was observed. Also, no clear relation between MCs in extracts and DNA damage was observed. ▸ Cyanobacteria have other microbiological agents, which affected lymphocytes. ▸ Determination of total threat from natural cyanobacterial blooms is recommended.
