Human Health Risk Assessment From Exposure to Toxic Metals in Soils and Leafy Vegetables in Smallholder Farms of Northeastern Brazil

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT This study assessed human health risks associated with exposure to potentially toxic metals (PTMs) in soils and leafy vegetables cultivated in smallholder agricultural systems in Northeastern Brazil. Soil and vegetable samples were collected from 18 agricultural areas and analyzed for cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), nickel

Melanoma Cells Exposed to Clomiphene Citrate Respond With Cell Cycle Arrest and Reduced Invasiveness

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Epidemiological studies have suggested that clomiphene citrate (CC) exposure may increase the risk of malignant melanoma, but mechanisms are unknown. We investigated the effects of CC on melanoma cell line A375. Cells were treated with CC at 2, 20, 200, and 2000 ng/mL, followed by assessment of cell viability and metabolism, cell cycle ...

Formulation‐Dependent Cytotoxic Effects of Commercial and Analytical‐Grade Mancozeb in C6 Glial Cells

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Mancozeb (MZ) is a widely used dithiocarbamate fungicide composed of manganese (Mn) and zinc (Zn) complexes. Increasing concern has been raised regarding its occupational and human health relevance, particularly due to its neurotoxic potential associated with Mn‐related cellular dysfunction.

The Impact of Genetic Polymorphisms on Genotoxicity (DNA Damage) Among Children Exposed to Environmental Mutagens: A Systematic Review

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Children, as a particularly vulnerable group, are more susceptible to these mutagens due to their developing immune systems, higher physiological vulnerability, and increased exposure through behaviors like outdoor play and hand‐to‐mouth activities. This review aims to investigate the relationship between these environmental exposures, genetic

Parental Exposure to Nanoplastics and Graphene Oxide Induces Transgenerational Toxicity in Caenorhabditis elegans

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Environmental pollution by emerging contaminants such as nanoplastics (NPs) and graphene oxide (GO) represents a growing threat to global health and ecosystems. This study investigated the effects of parental exposure, both isolated and combined, to 100 μg/L NPs (polystyrene, spherical, 100 nm) and 100 mg/L GO, using Caenorhabditis elegans as ...

Somatosensory Disturbance and Long‐Term Exposure to Methylmercury: A Comprehensive Review

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Chronic exposure to methylmercury remains a significant public health concern, particularly in populations with high fish consumption. Somatosensory disturbances are among the most frequently reported neurological manifestations, even at exposure levels below internationally established safety thresholds. This review aims to synthesize current

Biological Effects of Selenium‐Containing Ionic Liquids: Cytotoxicity, Mercury Interaction, and Antiproliferative Activity in Glioblastoma Cells

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Selenium (Se) is an essential micronutrient that participates in redox regulation and cellular homeostasis. Selenium‐containing ionic liquids (ILsSe) have emerged as hybrid compounds combining the properties of organoselenium molecules with the tunable features of ionic liquids.

Hematological and Genotoxic Effects of Subchronic Oral Exposure to a Mancozeb‐Based Fungicide in Female Mice

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT The extensive use of pesticides in modern agriculture has raised increasing concerns regarding the potential biological effects of repeated exposure to pesticide residues and commercial formulations. Mancozeb is a widely used ethylene‐bis‐dithiocarbamate fungicide; however, information on its hematological and genotoxic effects following ...
