The aim of this study was to demonstrate the absolute necessity of control experiments for a correct interpretation of mercury drop test results when applied to mechanistic studies of palladacycle-catalyzed reactions. It was shown that the interaction of diverse azapalladacycles with metallic mercury leads to the formation of organomercuric chlorides during the redox-transmetalation process. The structure of these organomercurials was confirmed by elemental analysis, 1H, 13C{1H}, and 199Hg{1H} NMR spectra, X-ray diffraction analysis, and DFT calculations. The behavior and properties of C,N-mercuracycles bearing the weak and labile N···Hg bond are discussed on the basis of the temperature dependence of the NMR spectra and calculated thermodynamic parameters of the dechelation process.

“…However, the dental amalgam waste is a source of mercury and requires special care as already mentioned. The practise of storing such waste in lidded pots containing water inside observed in this study is considered an adequate procedure according to researchers, who also pointed out the importance of the care to be taken with the amalgam residue in dental offices and advised their placement in unbreakable containers, air-tight sealed and with water or fixing solution inside [33]. Some studies have shown that no solution completely prevents the passage of the mercury vapour to the environment.…”

This study investigated how 14 dentists and five dental assistants dealt with the waste produced in a dental clinic of the public health service in the city of Rio de Janeiro. The method of direct observation associated with information obtained through a self-filling questionnaire and interviews with the participants were used. The findings pointed out the improper disposal of biological and sharps waste as well as those from dental amalgams. Only radiological waste received an appropriate treatment. Most health professionals ignored the law posing risks to the public health, environment and their own health. The lack of knowledge concerning the procedures recommended by health authorities is responsible for most of the negligent actions used in dentistry. Knowledge about the importance of the proper disposal of waste should begin in professional training courses.
