Cytogenotoxic and Molecular Assessment of Pyrethrins on Non‐Target Allium cepa Roots

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The pyrethrins, which form a part of naturally occurring insecticidal chemicals derived from chrysanthemum flowers, not only provide rapid knockdown of a broad spectrum of insect pests but are also widely used in integrated pest management due to a generally favorable safety profile, largely attributed to low mammalian toxicity.

Wildfire Ash Alters Freshwater Crustacean Behavior: Disentangling the Contributions of Suspended Macroparticles and Ash‐Induced Alkalinization

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Climate change and anthropogenic ignitions are intensifying wildfire frequency worldwide, elevating the risk of freshwater contamination by ash. In water, dissolved ash releases ions and other toxic constituents that increase pH and alter physicochemical conditions, while suspended ash particles may impose mechanical stress, disrupt behavior ...

Route‐Dependent Toxicity and Ecological Selectivity of Melaleuca alternifolia Essential Oil in Apis mellifera Linnaeus, 1758 (Hymenoptera: Apidae)

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT The intensification of agricultural practices has led to an increase in the use of insecticides, raising concerns about the exposure of non‐target organisms, particularly pollinators. In this context, plant‐derived essential oils have been proposed as environmentally friendlier alternatives due to their low persistence; however, their ...
