The association between mercury levels and autism spectrum disorders: A systematic review and meta-analysis [PDF]

open access: yes, 2017
Background & aims: The relationship between mercury and autism spectrum disorders (ASD) has always been a topic of controversy among researchers. This study aimed to assess the relationship between ASD and mercury levels in hair, urine, blood, red ...

Interaction between Molten Al‐Killed Mn–B Steel and Carbon‐Bonded MgO Refractories Based on Recyclates

open access: yesAdvanced Engineering Materials, EarlyView.
High‐temperature interactions between low‐sulfur Al‐killed Mn–B steel and MgO–C refractories (0 and 50 wt% recyclates) are studied via finger immersion tests (1600 °C). Surface‐active elements influence infiltration. MgO/CaS layer forms, along with spinel and calcium silicate.

Flow-based determination of total mercury in waters by flameless atomic absorption spectrometry

open access: yesO Mundo da Saúde
A flow injection analyzer is proposed for total mercury determination in natural waters by flameless atomic absorption spectrometry. Following a 30-min wet digestion with nitric acid under 90°C, in a closed Teflon vessel, a sample aliquot is inserted ...

Bioaccumulation of Mercury in Wilson’s Snipe from Alabama

open access: yesHuman-Wildlife Interactions, 2017
Mercury is a persistent, toxic heavy metal that can bioaccumulate in organisms, causing diseases and other health problems. Wilson’s snipe (Gallinago delicata) feed primarily on aquatic invertebrates, which makes them prone to mercury bioaccumulation. In

Measurement and Comparison of Mercury Concentration in Different Length Groups of Common Carp Muscle Tissue from the Shadegan Wetland [PDF]

open access: yes, 2016
Background: Due to the ecological importance of the Shadegan wetland as a valuable international wetland and some studies reporting high mercury concentration in its water and birds' tissues, this study was done to measure and compare the concentration ...

Influence of an Argon/Silane Atmosphere on the Temperature of a Thermal Plasma

open access: yesAdvanced Engineering Materials, EarlyView.
The influence of a silane‐doped argon atmosphere on the chemical composition and temperature of a thermal nontransferring argon plasma is investigated using optical emission spectroscopy. As a result of the high amount of free electrons resulting from the stepwise ionization and dissociation of the silane molecule, even a silane addition of 0.01 vol ...

Effects in the Anomalistic Period of Celestial Bodies due to a Logarithmic Correction to the Newtonian Gravitational Potential [PDF]

open access: yes, 2013
We study the motion of a secondary celestial body under the influence of the logarithmic corrected gravitational force of a primary one. This kind of correction was introduced by Fabris et al. (2009). We derive two equations to compute the rate of change

Interaction of Ladle Slag With Varying SiO2 Content and Recyclate‐Based MgO–C Refractories

open access: yesAdvanced Engineering Materials, EarlyView.
Ladle slags (CaO/Al2O3 = 1) with 1–20 wt% SiO2 were investigated in contact with industrial MgO–C refractories fabricated from fresh magnesia and 50 wt% recyclate. The sessile drop method at 1600°C reveals intensive gas formation, delayed slag infiltration in recyclate‐based samples, and, under high‐SiO2 slag, formation of a dense MgAl2O4‐rich ...

Factorial design analysis on the solubility of total mercury in reduction process = Análise do processo experimental na solubilidade do mercúrio total em processo redutivo

open access: yesActa Scientiarum: Technology, 2007
The dental wastewater can contribute to the total daily mercury load on the environment. Factorial design of experiments is useful to analyze factors that influence this solubility.

Impact of mercury atmospheric deposition on soils and streams in a mountainous catchment (Vosges, France) polluted by chlor-alkali industrial activity: The important trapping role of the organic matter [PDF]

open access: yes, 2006
Total atmospheric Hg contamination in a French mountainous catchment upstream from a chlor-alkali industrial site was assessed using Hg concentrations in the deepest soil horizon, in the stream bottom sediments, in river waters and in bryophytes.
