Polybrominated diphenyl ether (PBDE) flame-retardants have been identified as an emergent contaminants issue in many parts of the world. In vitro analyses were conducted to test the hypothesis that selected PBDEs congeners affect viability, apoptosis, and necrosis of thymocytes from laboratory-reared lake trout (Salvelinus namaycush). At current environmental levels (< 1 mg/L), effects of the tested PBDEs on thymocytes were negligible. However, at 100 mg/L, major effects were seen for congener brominated diphenyl ether 47 (BDE-47) and minor effects were seen for congener BDE-99.

The pollution potential of a municipal wastewater treatment plant (WWTP) in Bursa, Türkiye, in terms of organochlorine pesticides (ΣOCPs), polychlorinated biphenyls (ΣPCBs), and polybrominated diphenyl ethers (ΣPBDEs), was investigated in air samples. Concentrations were determined using polyurethane foam disk samplers at key processes, such as the aeration tank (AT) and settling chamber (SC) of the WWTP and the background area (BA) at an urban site. Atmospheric concentration levels of PBDEs at the SC are 1.

Sterilization is required for any biomedical device intended to be used in contact with the human body. Several studies have reported alterations in the bulk and surface properties of such devices after repeated sterilization cycles. These surface modifications may influence other clinical parameters.

The γ-butyrolactone scaffold, commonly present in natural products and bioactive compounds, has played a crucial role in the development of novel pesticides. In this study, a series of α-methylene-γ-butyrolactone derivatives containing a diphenyl ether moiety were designed and synthesized using the scaffold splicing strategy. Bioassays revealed that several target compounds demonstrated potent fungicidal activities, particularly against and .

The conversion of abundant lignin was of great significance for the utilization of biomass resources. In this study, lignin sulfonate (LS) was selected as a carbon-based support, which was successfully introduced into the NiCo-MOF structure. A series of lignin and MOF hybrid catalysts (NiCo-MOF-LS) with varying metal ratios of Ni and Co were synthesized via the hydrothermal method.
