Elevated temperatures increase chlorpyrifos toxicity in nile tilapia (Oreochromis niloticus) larvae

open access: yesDepik Jurnal
Global warming and the extensive use of chlorpyrifos pose serious threats to the hatching success, growth, and survival of Nile tilapia larvae (Oreochromis niloticus). This study aimed to evaluate the combined effect of chlorpyrifos toxicity and elevated

Coordination‐Tuned Iridium Single‐Atom Nanozymes Boost Multienzyme Activity for Colorimetric Sensing

open access: yesAdvanced Science, EarlyView.
Breaking the coordination symmetry of Ir single‐atom sites through asymmetric Ir–N3S1 engineering tailors interfacial electron transfer, oxygen activation, and multienzyme‐like catalytic pathways. Operando spectroscopy and theoretical modeling uncover the atomic‐level origin of activity enhancement, providing a strategy for designing multifunctional ...

Probabilistic health risk assessment of chlorpyrifos exposure among applicators on rice farms in Ghana

open access: yes, 2021
Human health risk assessments of exposures to non-carcinogenic occupational and environmental toxicants have mostly been undertaken using the Hazard Quotient (HQ) approach, which largely ignores variabilities in both exposures and associated adverse ...

Morpho-toxicology of chlorpyrifos to prolactin cells of a freshwater catfish, Heteropneustes fossilis - doi: 10.4025/actascibiolsci.v34i4.9134

open access: yesActa Scientiarum: Biological Sciences, 2012
In the present study, an organophosphorus compound Coroban (active ingredient chlorpyrifos – E.C. 20%) was used. In short-term exposure the fish were subjected to 0.8 of 96h LC50 value of chlorpyrifos (1.76 mg L-1) for 96h.

Guidelines for High‐Throughput Screening for Natural Products With Anti‐Aging Activity Based on Drosophila Intestinal Homeostasis

open access: yesAgriFood: Journal of Agricultural Products for Food, EarlyView.
ABSTRACT Aging represents a critical risk factor for chronic diseases, driving an urgent demand for interventions promoting healthy longevity. This study establishes standardized guidelines for high‐throughput screening (HTS) of anti‐aging natural products using Drosophila melanogaster, leveraging its intestinal homeostasis as a biomarker.

Exposures and health effects among field workers using the organophosphate chlorpyrifos [PDF]

open access: yes, 2004
Chlorpyrifos, an organophosphate pesticide moderately toxic to humans via inhalation and dermal absorption (LD50 oral, rat = 226 mg kg-1, LD50 skin, rabbits = 1265 mg kg-1), is widely used to eradicate termites in Australia.
