Introduction: The investigation of clinical and neurological impactations associated with exposure
to mercury levels in exposed populations is necessary in the Amazon. Objective: To analyze emotional and
motor symptoms of riverside dwellers exposed by diet in the municipalities of Itaituba and Acará, in Pará,
Brazil. Methods: Hair samples were collected to assess the total mercury (HgT). Demographic data as well as
emotional (depression, anxiety and insomnia) and motor (paresthesia, muscle weakness, loss of balance when
walking, tremors, limb pain and dysarthria) symptomatology data were obtained. Results: Mean levels of HgT
in Itaituba were significantly higher (p < 0.0001) than in Acará. Emotional symptoms were identified in 26
(26.5%) participants from Itaituba and in 24 (52.2%) from Acará. Specific motor complaints in Itaituba occurred
in 63 (64.3%) volunteers; the most frequently mentioned afflictions were limb pain (36.7%), paresthesia (32.6%)
and muscle weakness (27.5%). In Acará, 33 (71.7%) participants had motor symptoms, the majority of which
complained of paresthesia (54.3%), limb pain (52.2%) and tremors (34.8%). Average HgT levels in Itaituba in
those with emotional and motor symptoms were above the tolerable levels (6 μg/g) determined by the World
Health Organization. Conclusion: Results showed that mercury levels in emotional and motor symptoms in
Itaituba are higher than in riverside dwellers in Acará. Further studies, including the application of specific
qualitative and/or quantitative standard tests, as well as the investigation of other clinical signs are necessary. |
