Article Synopsis
- - Mercury has harmful effects on living organisms, while selenium is a necessary micronutrient that helps mitigate mercury’s toxicity, making the selenium-to-mercury (Se:Hg) ratio crucial for evaluating risks.
- - The study measured mercury and selenium levels in Whiskered Tern eggs in northern Iran, revealing higher mercury concentrations in the eggshell and greater selenium levels in the egg content, indicating selenium’s protective role against mercury.
- - Findings showed a significant negative correlation between mercury levels in the eggshell and the Se:Hg ratio, suggesting that mercury does not transfer effectively from eggshells to the embryos within the egg content.
Article Synopsis
- Plant invasion, especially by the Mesquite tree, is a big problem for natural habitats, especially in dry areas.
- Scientists studied how Mesquite spreads and changes the way other plants grow along the coast of Southern Iran using special satellite images.
- They found that areas taken over by Mesquite had increased plant growth, shown by a certain measure (NDVI), compared to areas with fewer Mesquite trees, indicating that monitoring these changes can help manage this invasive plant.
Since the year 2020, the use of plastic as a strategy to mitigate the spread of COVID-19 disease has been given substantial attention. Global environmental contamination of plastic creates waste and is a known threat to soil ecosystems as a main sink of microplastics. However, there is still considerable uncertainty about microplastics controlling soil properties alteration.

The present study uses a simple geostatistical technique to investigate the spatial variability of Cd and Pb in the Choghakhor Wetland to link the spatial variations of sediments to heavy metal contents in Myriophyllum spicatum. It was hypothesized that the heavy metal contents in the Choghakhor Wetland sediments impacted the concentration values in macrophytes.
