F Spadola, M Morici
Shell ulcers were diagnosed based on clinical appearance in 60 turtles. Under general anaesthesia, surgical curettage was performed using a burr mounted on a micro-grinder. A calcium hydroxide paste was applied to the debrided lesions before the application of restorative material. Lesions were completely filled with rapidly hardening silver amalgam. Treated terrapins were hospitalised in dry containers and later were housed in tanks with controlled temperature 24 hours. Fillings were found spontaneously expulsed at various periods after placement...

The methylmercury contamination of Minamata Bay during the WWII postwar period resulted in thousands of Japanese citizens suffering horrific neurological injury. Fear and miscommunication destroyed and changed family and social structure. In addition, the Minamata poisoning caused momentous changes in the civic discourse in Japan and was an instrumental event in the democratization of the country. This manuscript describes the effects that the environmental contamination and human poising had in the transition of Japan from a feudal society to a democratic one...

The Brazilian Amazon is known to be a region with high levels of mercury (Hg) in the environment and studies point to an association between high levels of natural mercury in the mother rock and the vast number of clandestine gold mines. Other studies already report the contamination of fish in this region, as well as high levels of Hg in biological material from environmentally exposed populations. On the other hand, this is one of the least developed regions of the planet and it is necessary to understand the vulnerability factors in these populations that may be intoxicated by this element...

Since the outbreak of methylmercury (MeHg) poisoning in Japan and Iraq, mercury (Hg) is classified as well-established teratogen. The Portuguese region of Aveiro faced some decades ago an environmental Hg contamination due to activities from a chlor-alkali plant. Until now, no apparent evaluation was conducted regarding prenatal exposure to Hg in this area. The main objectives of this study were to: i) assess maternal and fetal exposure to Hg in the Aveiro region using noninvasive biological matrices; ii) examine the influence of variables that may contribute to Hg exposure during pregnancy; and iii) improve knowledge regarding metal accumulation and distribution over the maternal-fetal-placental unit...

Mercury exposure is a common cause of metal poisoning which is biotransformed to highly toxic metabolites thus eliciting biochemical alterations and oxidative stress. Luteolin, a phenolic compound found in many natural products, has multiple biological functions. Our study was aimed to explore the biological effects of luteolin in a liver injury model induced in rats by mercuric chloride (HgCl2). Criteria for injury included liver enzyme, glutathione and malondialdehyde levels, histopathology, TUNEL assay, hepatocyte viability and reactive oxygen species levels...

The mercury (Hg) poisoning of Minamata Bay of Japan widely activated a global attention to Hg toxicity and its potential consequences to the aquatic ecosystem and human health. This has resulted to an increased need for a dynamic assembly, contextualization, and quantification of both the current state-of-the-art and approaches for understanding the cause-and-effect relationships of Hg exposure. Thus, the objective of this present review is to provide both hazardous toxic properties and toxicological update of Hg, focusing on how it ultimately affects the aquatic biota to potentially produce human health effects...

The development of nanoparticle-polymer-hybrid-based heterogeneous catalysts with high reactivity and good recyclability is highly desired for their applications in the chemical and pharmaceutical industries. Herein, we have developed a novel synthetic strategy by choosing a predesigned metal-anchored building block for in situ generation of metal (Pd) nanoparticles in the stable, porous, and crystalline covalent organic framework (COF), without using conventional reducing agents. In situ generation of Pd nanoparticles in the COF skeleton is explicitly confirmed from PXRD, XPS, TEM images, and (15)N NMR spectral analysis...

MnO2/CeO2-MnO2 hierarchical binary oxide was synthesized for elemental mercury (Hg(0)) removal from coal-fired flue gas. CeO2 in-situ grow on the surface of carbon spheres, and that CeO2@CSs acted as precursor for porous MnO2/CeO2-MnO2. XRD, Raman, XPS, FT-IR, and H2-TPR were selected for the physical structural and chemical surface analysis. The results indicated that the composite has sufficient surface oxygen and hierarchical porous structure. The Hg(0) removal experiments results indicated that MnO2/CeO2-MnO2 exhibited excellent Hg(0) removal performance, with an 89% removal efficiency of total 300min at 150°C under 4% O2...

OBJECTIVES: Despite restrictions, mercury continues to pose a health concern. Mercury has the ability to deposit in most parts of the body and can cause a wide range of unspecific symptoms leading to diagnostic mistakes. METHODS AND RESULTS: We report the case of severe mercury vapour poisoning after occupational exposure in a chloralkali plant worker that resulted in life-threatening respiratory failure, pneumomediastinum and quadriparesis. CONCLUSIONS: Prolonged mechanical ventilation and treatment with penicillamine and spironolactone was used with successful outcome...

BACKGROUND: Previous studies found that while internationally financed economic development projects reduced poverty when measured in terms of per capita GDP, they also caused indigenous people to become disassociated, impoverished and alienated minorities whose health status has declined to unacceptable lows when measured in terms of mercury poisoning and the burgeoning rate of suicide. In this study, we developed a needs assessment and a policy-oriented causal diagram to determine whether the impaired health of the people in this region was at least partially due to the role the country has played within the global economy...

Reductions of zooplankton biomasses and grazing pressures were observed during overfishing-induced trophic cascades and concurrent oil spills at global scales. Recent phytoplankton increments followed, once Fe-, P-, and N-nutrient limitations of commensal diazotrophs and dinoflagellates were also eliminated by respective human desertification, deforestation, and eutrophication during climate changes. Si-limitation of diatoms instead ensued during these last anthropogenic perturbations of agricultural effluents and sewage loadings...

Mercury (Hg) is toxic and hazardous metal that causes natural disasters in the earth's crust. Exposure to Hg occurs via various routes; like oral (fish), inhalation, dental amalgams, and skin from cosmetics. In this review, we have discussed the sources of Hg and its potential for causing toxicity in humans. In addition, we also review its bio-chemical cycling in the environment; its systemic, immunotoxic, genotoxic/carcinogenic, and teratogenic health effects; and the dietary influences; as well as the important considerations in risk assessment and management of Hg poisoning have been discussed in detail...

Elemental mercury poisoning commonly occurs through vapour inhalation as it is well absorbed through the lungs. Administering subcutaneous and intravenous elemental mercury is very uncommon with only a few isolated case reports in literature. We present a case of attempted suicide by subcutaneous injection of elemental mercury, an unusual substance used for suicide. As the attempt at self-injury was not confessed by the patient, diagnosis was challenging. Patient was treated with an initial diagnosis of cellulitis, but with repeated and persistent questioning, a history of self-injection of mercury into the arm was revealed...
