Arsenic (As) is commonly encountered in diverse water sources, such as saltwater, hot springs, wells, rivers, and lakes, with arsenate species prevalent in aquatic settings. Regrettably, anthropogenic activities, such as using arsenic-containing pesticides, industrial practices, and mining operations, have given rise to soluble As concentrations surpassing the acceptable threshold of 0.010 mg/L globally. The recurrent exposure of freshwater species, particularly fish, to low As levels triggers bioaccumulation, especially in the liver and kidneys, leading to hyperglycemia, enzyme activity loss, acute and chronic toxicities, and immune system malfunction. Exposure to elevated As concentrations from water or air pollution can result in short-term or long-term repercussions, including immune system toxicity and cytotoxicity in fish. © 2024 by the authors.

Honey bees (Apis mellifera L.) significantly enhance seed production, fruit set, and yield through pollination. However, the world is facing a major challenge of honey bee loss due to the excessive use of pesticides facilitated by technological advancements. Pesticides are harmful to pollinators and can cause lethal and sublethal effects through dermal contact, ingestion, or inhalation of contaminated air. Pesticide exposure in agricultural fields has led to honey bee toxicity, which affects their neurophysiological and immune systems and, consequently, their life cycle. This toxicity also leads to contamination of bee products, which can negatively impact human health, affecting the nervous and digestive systems, among others. While there is limited knowledge about the impact of pesticides on wild honey bees, it is crucial to understand this to guide agricultural practices and legislation aimed at safeguarding these important pollinators. It is, therefore, essential to take major steps to control pesticide toxicity in honey bees and prevent further harm. © 2024, AMG Transcend Association. All rights reserved.
Green Solution for Heavy Metal Removal: Utilizing Banana Peel Waste as a Sustainable and Effective Adsorbent

In recent years, the discharge of wastewater containing heavy metal ions, such as mercury (Hg), copper (Cu), lead (Pb), and iron (Fe), has posed a significant threat to the environment. Fortunately, research has found that banana peels contain elements, including sulfur, nitrogen, and carboxylic acid, which can effectively attract these heavy metals. The binding properties of banana peels can be retained for over ten cycles, making them a sustainable solution for water purification. This review summarizes recent studies on synthesizing porous carbons using banana peels and their application in water purification. Various synthesis methods and the adsorption mechanisms for removing heavy metals such as Hg, Cu, Pb, and Fe are discussed. Finally, this review concludes with a summary and highlights future prospects for research in this field. © 2024 by the authors.
