Recreator perspectives on harmful algal blooms in Ohio

Abstract

ABSTRACT Harmful algal and cyanobacterial blooms (HABs) are found in fresh waterbodies across the United States as well as around the world. In recent years, their frequency and intensities have increased. Caused by cellular overgrowth, the toxin produced by HABs can be harmful to aquatic organisms, livestock, and human life. However, as of to date, there is little study on the human psychological, behavioral and social aspects surrounding HABs. It is also unclear as to what recreators know and understand about HABs. However, since recreators use the waterbodies for various activities, they may be exposed to this environmental risk. As such, it is paramount that they be aware of the possible health impacts of HABs and behave sensibly to protect not only themselves but also their children and pets. This study interviewed recreators at Lake Harsha, Ohio, known to have HABs to better understand public HABs awareness, perceptions, behavior, and psychology. Overall, most recreators lacked basic knowledge of HABs and their risks. The ‘unaware’ and ‘cautious’ recreators, in particular, need to be better informed to reduce exposure risks. These findings can contribute to HABs mitigation and management, helping water managers bridge the gaps in HABs communication and creating better and more efficient methods of disseminating HABs knowledge and warnings.
