The study found that 59%of the pesticides applied within the L. Naivasha catchment are moderately to extremely hazardous, while more than 40% of the pesticides are moderately to highly persistence in the environment. 22% of the applied pesticides were of international concern because of their toxicity (moderately to extremely hazardous) and persistence (highly persistence).
