“…Mercury is deposited in the natural ecosystem through natural processes and the human activities which have the highest impact on nature, as they can nearly triple the amount of mercury in the atmosphere (17). In living organisms it may cause an increase in the production of the reactive oxygen species, because it leads to the depletion from the cell of major thiol-containing antioxidants which result in a condition known as oxidative stress (8,20).…”

A total of ninety white storks (Ciconia ciconia) of both sexes aged over one year of life and at a body weight between 2.8 – 4.15kg were subjects for observations. They were collected from the Warmia and Masuria region, and were rehabilitees of The Wild Birds Rehabilitation Center (Bukwald, Poland). The storks formed a group of birds that had wing damage like broken bones and were unable to fly. According to the severity of the case storks underwent three different kinds of treatment. Light cases of motion disability were submitted to wing or leg stabilization with adhesive bandages (treatment I), while middle and severe cases were additionally submitted to the administration of one (treatment II) or two capsules (treatment III) of propolis and pollen bee preparation (Apipol Farma’s Propolis Plus®) for two weeks, respectively. After the convalescence period a total of twenty three white storks did not recover and were euthanized and dissected. Post mortem samples of pectoral and femoral muscles as well as liver and kidney samples were taken. Mercury concentration was analyzed and the results revealed that the level in the kidneys and liver of white storks not receiving propolis preparation were significantly higher than that of those from treatment II and III. Contrary to this, the mercury concentration recorded in the pectoral and femoral muscles of the birds of treatment II and treatment III were significantly higher than that of the treatment without propolis preparation. The results showed that propolis and pollen bee preparation can reduce the level of mercury in kidneys and liver, but has no influence on the reduction of mercury in pectoral and femoral muscles. .

“…They have the opportunity to prey in different areas of Europe, Asia and Africa according to their migration, and at the same time to assimilate the mercury from food (5,11). In wildlife birds, most cases of mercury poisoning result in an emaciation syndrome and a variety of sub lethal effects that may act together to cause death (2,17).…”

“…Além dos efeitos supracitados, o mercúrio prejudica o sistema reprodutor de mamíferos. A exposição ao mercúrio reduziu os níveis de espermatozoides, bem como de hormônio folículo estimulante (FSH) e de testosterona 53,54 , prejudicando globalmente a função reprodutora masculina.…”

Resumo:A contaminação ambiental e as exposições ocupacionais por mercúrio estão relacionadas a diversos problemas de saúde desde o período fetal. Pelo fato do amálgama ser um material restaurador amplamente usado em odontologia, em virtude da sua facilidade de utilização e do baixo custo, o objetivo deste trabalho foi elaborar uma revisão bibliográfica sobre os aspectos ambientais, ocupacionais e toxicológicos da contaminação mercurial. Foi realizada uma revisão utilizando as bases de dados Medline, ISI e LILACS cobrindo o período de 2004 a 2015. O mercúrio está relacionado à redução do crescimento ponderal e desenvolvimento cognitivo de crianças, bem como a distúrbios psico-afetivos, autismo, doença de Alzheimer, infertilidade masculina e problemas cardiometabólicos. Embora a contribuição das amálgamas dentárias para a liberação de mercúrio não seja tão expressiva comparada à contaminação por atividades de garimpo e outras fontes, seu uso deve começar a ser restrito para reduzir as emissões de mercúrio. Abstract:Environmental pollution and occupational exposures by Mercury have been associated with many health problems since the fetal life. Since amalgam is widely used in dentistry due to its ease use and lower cost, the objective of this work was to elaborate a review regarding Mercury pollution and environmental, occupational and health aspects. A review covering 2010 to 2014 period using Medline, ISI, and LILACS databases were done. Mercury is associated with reduction of physical growth and cognitive development in children as well as psycho-affective disturbancies, autism, Alzheimer's disease, male infertility, and cardiometabolic problems. Although the amagalm contribution to Mercury release is not so relavant as compared to gold-mining and other sources its use should beggin to be restricted in order to reduce Mercury emissions.

Abstract-Artisanal gold mining activities in developing countries are still in concern with environmental and health issues regarding the impact which results from the activities. Amalgamation technique using mercury was commonly applied in extracting gold from the ore. During the process, mercury releases into the environment in its metallic form and mercury vapor. Mercury releases to environment can harm population who work or live near mining area. Mercury is a highly toxic metal and it can penetrate nervous systems as the main target organ. Acute and chronic neurological disturbances can also be experienced by the communities. The aim of this study was to determine the relationship between occupation in the mining process, length of time of mercury exposure and neurological status disturbances in communities near artisanal gold mining area in West Aceh, and is known now as Aceh Jaya district, Aceh Province, Indonesia. A cross sectional design was conducted with 78 respondents who lived in villages namely, Paya Seumantok, Panggong, and Curek. Samples were collected by random sampling and respondents were interviewed and given general physical examination. Data were analyzed by Chi-Square test at α = 0.05. The results of this study showed that occupation in mining process has relationship with neurological status disturbances (p=0.004) whereas length of time of mercury exposure showed no relationship to neurological status disturbances (p=0.650). Respondents have experienced neurological disturbances such as headache (48.7%), insomnia (37.2 %), tremor (10.3%), memory loss and mood changes (9.0%), hearing impairment and somatosensory disturbances (3.8%). It can be concluded that efforts for monitoring and evaluation on artisanal gold mining in the areas have to be made by local government and stakeholders to prevent widespread of epidemy on mercury disasters. It is also needed to follow up the neurological status disturbances of the respondents clinically through intensive examination.
