Tetrabromobisphenol A (TBBPA) is a nonregulated brominated flame retardant with a high production volume, and it is applied in a wide variety of consumer products. TBBPA is ubiquitous in abiotic matrices, wildlife and humans around the world. This paper critically reviews the published scientific data concerning the disposition, metabolism or kinetics and toxicity of TBBPA in animals and humans. TBBPA is rapidly absorbed and widely distributed among tissues, and is excreted primarily in the feces. In rats, TBBPA and its metabolites have limited systemic bioavailability. TBBPA has been detected in human milk in the general population. It is available to both the developing fetus and the nursing pups following maternal exposure. It has been suggested that TBBPA causes acute toxicity, endocrine disruptor activity, immunotoxicity, neurotoxicity, nephrotoxicity, and hepatotoxicity in animals. Cell-based assays have shown that TBBPA can induce reactive oxygen species in a concentration-dependent manner, and it promotes the production of inflammatory factors such as TNF α, IL-6, and IL-8. Cells exposed to high levels of TBBPA exhibit seriously injured mitochondria and a dilated smooth endoplasmic reticulum. This review will enhance the understanding of the potential risks of TBBPA exposure to ecological and human health.

Adequate levels of thyroid hormones (THs) in the fetal brain are vital for early neurodevelopment. Most of the TH in fetal brain is derived from circulating thyroxine (T4), which gets locally converted into the biologically active triiodothyronine (T3) by deiodinase enzymes. One of the major routes of TH into the brain is through the blood-cerebrospinal fluid barrier (BCSFB).

Congenital hypothyroidism (CH) has been reported as a prevalent endocrine disorder in newborns. Endocrine disrupting chemicals (EDCs) have been widely detected in humans and can influence endocrine function, especially thyroid function, and neonates as a susceptible population may be more prone to suffer from CH through exposure to various EDCs. In this study, the concentrations and composition profiles of several typical EDCs were determined in 266 serum samples collected from newborns with (n = 136) and without CH (n = 130) in Beijing, China from 2018 to 2020.

Tetrabromobisphenol A (TBBPA) poses significant ecological risks owing to its toxicity; however, its specific effects on toxin-producing cyanobacteria in aquatic environments remain poorly understood. This study systematically investigated the effects of TBBPA at concentrations ranging from 100 ng/L to 100 mg/L on Microcystis aeruginosa (M. aeruginosa) by examining growth, photosynthesis, toxin production, antioxidant responses, and molecular-level changes.

Perfluorooctanoic acid (PFOA) and tetrabromobisphenol A (TBBP-A) are emerging environmental contaminants with recognized potential health and ecological risks. This study investigated the effects of PFOA and TBBP-A exposure on the global of metabolites of silkworm gut with GC-MS metabolomics. Our results revealed distinct metabolic alterations in silkworms exposed to PFOA and TBBP-A, highlighting their differential impacts on silkworm health and productivity.

Tetrabromobisphenol A (TBBPA) is an aquatic environment's prevalent pollutant, posing a great threat to the health of aquatic animals. The intestine is a key organ for nutrient absorption as well as an important barrier to prevent pollutants from invading the body of fish. Exploring the effects of pollutants on the intestine is of great significance for maintaining fish health.
