Research progress on cognitive dysfunction induced by occupational noise and combined exposure to heavy metals
Exposure to occupational noise and heavy metals are common occupational hazards in workplaces.Occupational noise exposure not only leads to noise-induced hearing loss but also cognitive dysfunction.Exposure to common heavy metals such as lead,manganese,and cadmium during work is closely related to cognitive dysfunction in workers.Combined exposure to noise and heavy metals is common in workplaces.However,current research on the combined effects of exposure to occupational noise with lead or manganese on workers'cognitive function is not comprehensive or systematic.The method for cognitive dysfunction identification varies,leading to a lack of comparability.And the causality between occupational exposure and cognitive dysfunction in workers has not been clarified.Therefore,studying the cognitive dysfunction due to combined exposure to noise and common heavy metals is of great significance for workers'occupational health.In the future,it is necessary to unify the method for cognitive dysfunction identification and conduct systematic and comprehensive research on the effects,mechanisms,and combined effects of exposure to occupational noise with lead,manganese,cadmium,and other heavy metals on workers'cognitive dysfunction,to ensure the occupational health rights and interests of workers.
