To study the effects of a mobile phone exposure on the swimming behaviour and morphological and physiological parameters of the protozoan Paramecium caudatum.
23-35 protozoans were investigated for each exposure/sham exposure condition (11 individuals for physiological parameters).
|Exposure duration||continuous for at least 2 min, at least for four times|
|Setup||cell phone in standby position; petri dish with a few or a few hundred individuals of Paramecium caudatum placed 1-2 cm from the mobile phone's antenna or directly on the phone|
Exposed individuals moved more slowly and more sinuously than individuals of the control group. The physiology of the exposed protozoa was also affected: they became broader, their cytopharynx appeared broader, their pulse vesicles had difficulties in expelling their content outside the cell, their cilia moved less efficiently, and the trichocysts became more visible.
All these effects might result from some bad functioning or damage of the cell membrane.
