Background: Contagion of aquatic ecosystems to heavy metals especially mercury (Hg) has risen concerns about healthiness of marine organisms. Organic mercury compounds are highly toxic for animals, and its detection in various samples is frequently needed. In present study we have described a new method for measurement of organic mercury and total mercury concentration in great cormorants (ph...

Background and purpose: Mercury contamination is still a threat to the environmental and public health in both developed and developing countries. The aim of this study was to determine the total and organic mercury content in the muscle of goldfish (Carassius aurathus gibelio) obtained from the east and west of Anzali Wetland. We also assessed the health risks involved in consumption of this f...

To clarify the maternal-fetal transfer of mercury across the placenta, inorganic and organic mercury were determined in 41 paired samples of maternal blood, placenta, umbilical cord blood and umbilical cord obtained from pregnant women who had no particular exposure to mercury compounds in their history. Both inorganic and organic mercury were detected in all the samples but the ratio of organi...

Inorganic and organic mercury was measured in the red cells, plasma, and urine of five laboratory workers to examine the effect of D-penicillamine. The workers had had no particular exposure to mercurials. Before and during administration of D-penicillamine, inorganic mercury levels in plasma were significantly correlated with those in urine or 24-hour urinary outputs, but no significant correl...

Ishihara, N., Shiojima, S., and Suzuki, T. (1974). British Journal of Industrial Medicine, 31, 245-249. Selective enhancement of urinary organic mercury excretion by D-penicillamine. This report deals with the study of a patient who was suspected of having mercury vapour poisoning and was treated with D-penicillamine. D-penicillamine by mouth enhanced the urinary excretion of organic but not in...

SHISHIDO , S. and SUZUKI, T. Mercury in Human Hair: A Comparative Study by Using Two Different Methods of Atomic Absorption and Neutron Activation Analysis. Tohoku J. exp. Med., 1974, 113 (4), 351-356 Magos (1971) reported a new method of atomic absorption spectrometry for selective and simple determination of inorganic and organic mercury. To investigate the reliability of Magos's method, the ...

Mercury is found in the environment as elemental mercury, inorganic mercury or organic mercury (ethyl-, methyl-, alkyl-, or phenylmercury). In our environment it is present in thermometers, thermostats, dental amalgams, paint, cosmetic products, laxatives, diuretics and antiseptics. Organic mercury is the most toxic and most frequent form of mercury exposure, found in fish, poultry, pesticides ...

AIM To compare the total and organic mercury content in sea-fish samples from Croatia, where fishing occurs in a closed part of the Mediterranean Sea, and from other countries fishing mostly in the oceans. METHOD During 1997, we collected at the Zagreb fish market a total of 115 samples of fifteen kinds of fish including bathypelagic, pelagic and elasmobranch fish, caught in the wider coastal...

The aim of this study was to examine the experimental uptake of mercury and the enzymatic response, i.e., glutathione S-transferase (GST) activity, to this metal introduced into the medium under organic (methylmercury chloride) and nonorganic (mercury chloride) forms. Shoots of Posidonia oceanica were collected in a nonpolluted area in the northwestern Mediterranean Sea and were treated in aqua...
