Heterogeneous Exhumation Mechanisms in Neoproterozoic Collisional Metamorphism: P–T Constraints From Pelotas and Punta del Este Terranes, Southern Brazil and Uruguay

open access: yesGeological Journal, EarlyView.
Petrography, thermobarometry, and pseudosection modelling reveal peak metamorphic conditions of 3–7.5 kbar and 520°C–800°C in Tonian‐Cryogenian orthogneisses of the Dom Feliciano Belt. Metamorphic field gradients of 27°C/km–39°C/km and variable exhumation mechanisms support correlation of these units as remnants of a Himalayan‐type Piratini Orogeny ...

Developmental and Behavioral Effects of Arsenobetaine in Zebrafish (Danio rerio)

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Arsenobetaine (AsB) is a prevalent organoarsenical in aquatic environments and is generally regarded as nontoxic. Despite its widespread occurrence, the developmental and neurobehavioral toxicity of AsB has not been systematically investigated.

Mercury cycling during the last glacial period in Arctic Lake El'gygytgyn, NE Russia

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT Tectonic processes play a key role in the global mercury (Hg) cycle on geological timescales, by mobilising Hg from deep Earth reservoirs to the surface. These natural fluxes also introduce a dynamic component to the terrestrial Hg cycle that can interact with other environmental signals and influence Hg delivery to sedimentary records.

Health risk assessment of heavy metal accumulation in fruits exposed to geothermal waters: a case study and global implications

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND The present study investigated the potential health risks of heavy metals (HMs) in the fruits and leaves of mulberry and sour cherry trees exposed to water from Sivas geothermal basin (Turkey). RESULTS The target HMs were ranked according to their hazard index as: Cd < Pb < Zn < Cu < Ni < Mn < Cr. The total hazard index for mulberry

Energy Options to Reduce Deforestation Using EKC Model: A Region‐Based Longitudinal Approach

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Forests are carbon storage that can reduce carbon emissions, so deforestation (decrease in forest area) is a serious threat to environmental sustainability. Indonesia is a large carbon sink due to its large forests. However, deforestation is quite high due to economic activities that use fossil energy.

The Combined Effects of Variable Viscosity and Thermal Conductivity of An Unsteady Casson Fluid Flow Along a Vertical Porous Channel With Convective Cooling Walls, Using the Bivariate Spectral Local Linearization Method

open access: yesMathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This study examines the combined impact of different thermal conductivity and viscosity on unsteady non‐Newtonian Casson fluid flow of incompressible, electrical conductivity in a porous vertical channel with convective cooling walls, uniform magnetic field, and constant pressure gradient.
