Adaptation to extreme environments: A review of Antarctic fish physiology

Journal of Fish Biology, EarlyView.
Abstract Having evolved in the chronically cold and thermally stable waters of the Southern Ocean (SO) for millions of years, Antarctic fish possess a suite of physiological specializations that enable them to survive at temperatures near the freezing point of seawater. Adaptations include the evolution of antifreeze proteins, modifications of membrane

Tissue damage after acute intoxication by polychlorinated biphenyls (PCBs) in cockroaches Blattella germanica

European Journal of Histochemistry, 2009
It is common knowledge that polychlorinated biphenyls (PCBs) represent a serious threat to the health of both vertebrates and invertebrates. As far as the former are concerned, especially as regards human beings, a broad literature describes the direct ...

Half a Century of Per‐ and Polyfluoroalkyl Substances in Northern Gannet Eggs: Impact of Regulations

Journal of Applied Toxicology, Volume 46, Issue 11, Page 4085-4098, November 2026.
ABSTRACT Per‐ and polyfluoroalkyl substances (PFAS), known as “forever chemicals”, are persistent organic pollutants that have been widely used in the industry across the globe for many decades. Their chemical stability, bioaccumulation, and toxicity pose major environmental and health risks. This study examines temporal trends in the concentrations of

Serum concentrations of polybrominated biphenyls (PBBs), polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) in the Michigan PBB Registry 40 years after the PBB contamination incident

Environment International, 2020
Widespread polybrominated biphenyls (PBBs) contamination occurred in Michigan from 1973 to 1974, when PBBs were accidentally substituted for a nutritional supplement in livestock feed. People who lived in the state were exposed to PBBs via several routes

Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus From Waterbodies in the Northeastern United States and Canada: Identification of Risk Factors

Journal of Fish Diseases, Volume 49, Issue 11, November 2026.
ABSTRACT Melanistic lesions, including non‐raised black areas due to proliferations of melanocytes and melanomacrophages in the dermis and epidermis, as well as raised black areas consistent with melanoma, are described in brown bullhead (BBH) Ameiurus nebulosus from three water bodies in the northeastern United States and Quebec, Canada.

A practical approach to the degradation of polychlorinated biphenyls in transformer oil

, 2005
A practical and efficient disposal method for hydrodechlormation of polychlorinated biphenyls (PCBs) in transformer oil is reported. Transformer oil containing PCBs was treated by nanometric sodium hydride (nano-NaH) and transition metal catalysts.

Organic Mixed‐Valence π‐Electron Systems—Current Status and Challenges

Asian Journal of Organic Chemistry, Volume 15, Issue 10, October 2026.
This review discusses the progress and challenges in organic mixed‐valence π‐electron systems, focusing on trends such as the exploration of multi‐redox‐centered mixed‐valence multi‐radical states arising from the interplay between charge transfer and spin interactions and the realization of novel mixed‐valence states through the effective utilization ...

Polychlorinated biphenyls – toxicity and risks

Croatian Journal of Food Science and Technology, 2012
Polychlorinated biphenyls (PCBs) are synthetic organochlorine compounds differing by their physico-chemical and toxicological properties and tend to bioaccumulate and biomagnificate in the environment and within the food chain.
