1. Mercury Exposure in a Riverside Amazon Population, Brazil: A Study of the Ototoxicity of Methylmercury
Introduction Mercury poisoning causes hearing loss in humans and animals. Acute and long-term exposures produce irreversible peripheral and central auditory system damage, and mercury in its various forms of presentation in the environment is ototoxic.
Objective We investigated the otoacoustic emissions

2. Evaluation of toxic effects of methylmercury in the retina of fotoreceptores Hoplias malabaricus (BLOCK, 1794), trahira, through histopathological techniques / Avaliação dos efeitos tóxicos do metilmercúrio na retina de duas espécies de teleósteos: Hoplias malabaricus e Danio rerio, utilizando um conjunto de biomarcadores biológicos
Em exposições especificamente relacionadas ao metilmercúrio (MeHg), o principal órgão alvo é o Sistema Nervoso Central (SNC). Os efeitos morfológicos do metilmercúrio nos fotorreceptores da retina de Hoplias malabaricus, traíra, foram investigados através de técnicas histopatológicas. Os exemplares de traíra foram distribuídos em três grupos:

3. O comportamento do metilmercúrio (metilHg) no ambiente
Methylmercury is the most hazardous mercury species known. Due to its high stability, lipid solubility, and ionic properties, this compound shows a high ability to cross membranes in living organisms, damaging the central nervous system, mainly the brain, and the effects of chronic poisoning are progressive. In this paper some aspects related to the toxicity

4. Cytogenetic damage related to low levels of methyl mercury contamination in the Brazilian Amazon
The mercury rejected in the water system, from mining operations and lixiviation of soils after deforestation, is considered to be the main contributors to the contamination of the ecosystem in the Amazon Basin. The objectives of the present study were to examine cytogenetic functions in peripheral lymphocytes within a population living on the banks of the T

5. Methylmercury poisoning, Clinical follow-up and sensory nerve conduction studies.
Methylmercury poisoning occurred in four cases after passage of methylmercury through the food chain. The neurological damage in all four cases was severe. The damage was greater at younger ages with maximum involvement in the case of transplacental poisoning. Significant recovery occurred in two cases, but on six-year follow-up two cases remained severely i

6. Psychiatric aspects of methylmercury poisoning
Forty-three patients with methylmercury poisoning were studied; 74·4% showed some degree of depression. Their blood levels of mercury were higher than the average values for the whole group, and considerably higher than the blood levels of the non-depressed patients. Irritability was observed in 44·2% of the patients, all except one of the 19 being under 3
