Microcystin Lr Survey Essay
Makheraet.al (2010) did the study on monitoring 0f microcystin-LR in Luvuvhu River catchment: Implication for human health. Cyanotoxins in surface drinking water sources are known to pose a threat to human health, of which microcystin-LR is the most investigated. The main aim of the research was to assess the levels of microcystin-LR in Luvuvhu River catchment and to assess the physiochemical parameters that may promote the growth of cyanobacteria. The level of microcystin-LR in some of the sampling sites was<0.18 µg/l. The water quality of the shallow hand dug wells and reservoir water were almost similar. The outflows had slightly high levels of nitrates and no soluble reactive phosphates in comparison with inflows, suggesting that the …show more content…
