Neurotoxicity from prenatal and postnatal exposure to methylmercury
Abstract
The extent to which postnatal methylmercury exposure contributes to neurobehavioral delays is
uncertain. Confounding may occur because the child's dietary exposure likely correlates with the
mother's. This conundrum was examined in the Faroese birth cohort 1 born in 1986–1987.
Exposure parameters included mercury concentrations in maternal hair at parturition, cord blood,
and child blood and hair at the age-7 clinical examination (N = 923). In regression analyses, the
child's current blood-mercury at age ...

Mercury contamination in Southern New England coastal fisheries and dietary habits of recreational anglers and their families: Implications to human health and issuance of consumption advisories
Abstract
Total mercury (Hg) was measured in coastal fishes from Southern New England (RI, USA), and Hg exposure was estimated for anglers and family members that consumed these resources. Fish Hg was positively related to total length (n = 2028 across 7 fish species), and interspecies differences were evident among legally harvestable fish. Many recreational anglers and their families experienced ...

Low-Level Toxic Metal Exposure in Healthy Weaning-Age Infants: Association with Growth, Dietary Intake, and Iron Deficiency
Abstract: Even low levels of toxic metal exposure (As, Cd, Hg, and Pb) in infancy might be
harmful to children’s development. This study investigated toxic metal exposure on healthy
weaning-age infants and its relationship with growth, diet, and iron/anemia status. The weight,
height, head circumference, whole blood levels of four toxic metals, hemoglobin, and serum ferritin
of healthy infants was measured. Among 210 infants with a median age of 11.4 months ...

Infant Exposure to Metals through Consumption of Formula Feeding in Mekelle, Ethiopia
This study aimed at determination of heavy metals (cadmium, lead, and zinc) in milk-based infant formulas collected fromMekelle, Ethiopia, and their associated health risks to the infants through consumption of these products. The infant feeding samples were dry-ashed in a muffle furnace followed by digestion in nitric acid and the resulting solutions were analyzed by flame atomic
absorption spectrophotometer. Cadmium was not detected in the samples while the levels of lead and zinc ranged fromnot ...

Identification of toxic metals in human embryonic tissues
A b s t r a c t
Introduction: The cause of a significant number of miscarriages remains unexplained. There is a need to identify the potential role of environmental, dietary and lifestyle factors in the risk of pregnancy loss. The present study was the first to investigate the content of miscarried embryonic material with respect to eight metals (aluminium, cadmium, chromium, copper, manganese,
nickel, lead and zinc).
Material and methods: Embryonic tissue samples (n = 20) were obtained from women undergoing misoprostol-i...

Heavy metal contamination of prenatal vitamins
AB S T R A C T
Prenatal vitamins are often consumed daily during gestation and postnatally for up to 18–24 months with the belief that supplementation achieves better outcomes. Detrimental effects of gestational exposure to adverse chemical agents are gathering increasing attention. This study was designed to assess toxic element contamination in prenatal supplements. Twenty-six commonly used prenatal vitamin brands including one prescription brand were collected from Canadian health-food outlets and pharmacies, and tested for toxic ...

Harmful Elements (Al, Cd, Cr, Ni, and Pb) in Wild Berries and Fruits Collected in Croatia
Abstract: Fruits and vegetables are considered a beneficial contribution to the human diet.
Especially, berries contain a great deal of bioactive compounds, such as anthocyanins, organic
acids, tannins, phenols, and antioxidants. Apart from organic substances, inorganic nutrients are
also present in fruits. Some metals and metalloids are essential for humans, whilst others may
exhibit harmful effects. Wild grown berries, collected in so-called unpolluted areas, are considered
to be free of any ...

Exposure to toxic metals triggers unique responses from the rat gut microbiota
Our understanding of the interaction between the gut microbiota and host health has recently
improved dramatically. However, the effects of toxic metal exposure on the gut microbiota remain
poorly characterized. As this microbiota creates a critical interface between the external environment and the host’s cells, it may play an important role in host outcomes during exposure. We therefore used 16S ribosomal RNA (rRNA) gene sequencing to track changes in the gut microbiota composition of rats exposed to ...
