Post Minamata incident there has been awareness about mercury toxicity even among the general public. Previous researches contributed a vast amount of data regarding acute mercury exposure, but gradually information about the low dose [Ninomiya, T., Ohmori, H., Hashimoto, K., Tsuruta, K., Ekino, S., 1995. Expansion of methylmercury poisoning outside minamata: an epidemiological study on chronic...

ticular concern are “heavy metals,” which occur naturally in the earth’s crust and are defined in physiochemical terms as metals with a density at least 5 times as great as water. This definition translates into an approximate heavy-metal minimum density of 5, and—in addition to cadmium, lead, and mercury—the metals zinc, copper, iron, cobalt, nickel, tin, manganese, and molybdenum also qualify...

Recently, worldwide media attention has focused on the effects of mercury pollution on the environment, and the resultant health consequences in pregnant women, fetuses, and children.1 Mercury occurs naturally in the environment and is a recognized neurotoxin at high doses.2 It cannot be broken down, thus making it one of the elements of the periodic table. Mercury naturally cycles through the ...

BACKGROUND/AIM Any forms of mercury have toxic action on the majority of organs, especially kidneys. The major source of professional exposure to mercury are departments for the production of chlorine which use mercury as catode. The aim of the study was to prove that chronic exposure to elementary mercury low concentrations could cause asymptomatic damages of the kidneys. METHODS A total of ...

BACKGROUND The aim of this study was to evaluate the toxic effects of mercury on retinal nerve fiber layer thickness (RNFLT), macular thickness (MT), and choroidal thickness (CT) by using spectral-domain optical coherence tomography (SD-OCT) in battery industry workers who had been chronically exposed to mercury. MATERIAL/METHODS Battery factory workers (n=31) and healthy non-factory employee...

Changes in urinary porphyrin excretion patterns (porphyrin profiles) have been described in response to a variety of drugs and chemicals. The present studies were conducted to define the specific changes in the urinary porphyrin profile associated with prolonged exposure to mercury and mercury compounds. In rats, exposure for a prolonged period to mercury as methyl mercury hydroxide was associa...
