a series of specific toxicological effects including bioaccumulation of the pollutant, histological changes and influences on liver tissue were examined in the roach fish (rutilus rutilus) after the exposure to graded sublethal concentrations (10 , 30 , 50 μg hg/l) of mercury chloride (mc). histopathological changes, such as oedema, vacuolization, pyknotic nucleus, telangiectasis, and degenerat...

Impairments in social relatedness and communication, repetitive behaviors, and stereotypic abnormal movement patterns characterize autism spectrum disorders (ASDs). It is clear that while genetic factors are important to the pathogenesis of ASDs, mercury exposure can induce immune, sensory, neurological, motor, and behavioral dysfunctions similar to traits defining or associated with ASDs. The ...

BACKGROUND A growing body of evidence suggests that exposure to toxic metals occurs through diet but few studies have comprehensively examined dietary sources of exposure in US populations. PURPOSE Our goal was to perform a novel dietary-wide association study (DWAS) to identify specific dietary sources of lead, cadmium, mercury, and arsenic exposure in US children and adults. METHODS We co...

OBJECTIVES To examine whether the dose-effect relationship for developmental mercury neurotoxicity is affected by variable mercury exposure during pregnancy. METHODS The study was based on a birth cohort of 1022 children born in the Faroe Islands between March 1986 and December 1987. Neurobehavioral performance of 917 children (90%) was assessed at age 7. Intrauterine methylmercury exposure w...

This report reviews current literature regarding the association of the pharmaceutical preservative thimerosal and other mercury exposures with the risk for autism. The evidence presented here does not support a causal association between autism and mercury exposure from the preservative thimerosal. The risk for autism from other mercury exposures such as from dental amalgam restorations or env...

From a public health perspective, there is growing concern about dietary mercury intake as the most important source of mercury exposure. This study was performed to estimate dietary mercury exposure and to analyze the association between mercury intake and blood mercury levels in Koreans. The study subjects were 553 adults, comprising a 10% representative subsample of the Korean National Envir...

The determination of adjustment method of urinary mercury in spot urine is one of the important issues in assessing the health risks of mercury workers. But there have been debates about whether creatinine or other forms of correction for urinary concentration are better in reducing the variation of urinary mercury. We evaluated four adjustment methods-specific gravity, creatinine, log creatini...

OBJECTIVES To determine the genotoxic damage among artisanal and small-scale mining workers exposed to mercury. MATERIALS AND METHODS Observational cross-sectional study which evaluated mercury-exposed workers (n=83), whose cells were collected by mouth swab for further staining, microscopic observance, micronuclei count, and other nuclear alterations. 24-hour urine was also collected for the...
