Associations between serum persistent organic pollutants and type 2 diabetes in a multipollutant analysis using repeated measurements in the Tromsø Study

Frontiers in Environmental Health
IntroductionPersistent organic pollutants (POPs) occur as correlated mixtures, and serum concentrations may vary over time due to changes in exposure and toxicokinetic processes.

Presence of Nationally Banned Carbamates and Organophosphate Pesticides in Wild Carnivores, Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT As top predators, terrestrial carnivores face great risk of pesticide exposure and serve as sentinels of environmental contamination. Additionally, terrestrial carnivores are frequently threatened by intentional or secondary poisoning with highly toxic compounds, such as carbamates and organophosphates.

Chlorine Isotope Effects and Composition of Naturally Produced Organochlorines from Chloroperoxidases, Flavin-Dependent Halogenases, and in Forest Soil

, 2013
The use of stable chlorine isotopic signatures (delta Cl-37) of organochlorine compounds has been suggested as a tool to determine both their origins and transformations in the environment.

Photocatalytic and Biotechnological Strategies for Remediation of Persistent Organic Pollutants: Mechanisms, Toxicity, and Antimicrobial Perspectives

Environmental Toxicology, EarlyView.
ABSTRACT Persistent organic pollutants (POPs) pose significant ecological and human health risks due to their persistence, bioaccumulation, toxicity, and global distribution. Conventional remediation methods are often inadequate for achieving complete mineralization, demonstrating the need for advanced and substantial approaches.

Observation of varied characteristics of chlorine isotope effects of organochlorines in dechlorination reactions on different types of electron ionization mass spectrometers

, 2020
Dechlorination reactions of organochlorines can commonly take place in fragmentation on electron ionization mass spectrometry (EI-MS) and collision-induced dissociation (CID) on electron ionization tandem mass spectrometry (EI-MS/MS), possibly ...

Embryotoxic Effects of Monosodium Methyl Arsenate (MSMA) on Gallus gallus: Morphological and Morphometric Evidence of Developmental Disruptions

Environmental Toxicology, EarlyView.
ABSTRACT Anthropogenic activities and the large volume of compounds released into the environment are sources of contamination for plants, animals, and humans. The herbicide monosodium methyl arsenate (MSMA) ranks among the best‐selling agricultural pesticides in Brazil.
