As the coverage of cyanobacteria in the desert can be considerable (Richeret al., 2012), and as these dust storms are known to contain cyanobacteria (Griffin, 2007), it is therefore possible that cyanotoxins may be present in dust storms. The effects of continued exposure to dust containing cyanobacteria through inhalation in dust storms should not be overlooked and it is possible that inhalation of cyanobacteria through dust storms could lead to an elevated adverse health risk (Metcalf et al., 2012).
