Fate of 2,4,6-tribromophenol (TBP) in environmental matrices is obscure. We used C-tracer to investigated mineralization, transformation, and non-extractable residue (NER)-formation of TBP in a soil under continuously oxic, continuously anoxic, and anoxic-oxic alteration conditions. In all cases, TBP rapidly dissipated, mineralized to CO, and formed NERs in the soil. Considerable amounts of transformation products (2-12%) were detected during the incubation. Marked mineralization (13-26%) indicated that soil microorganisms used TBP as their energy source. About 62-70% of the initial radioactivity was transformed into NERs, being mainly attributed to binding to humic and fulvic acid fractions. TBP transformation was significantly faster under oxic conditions than under anoxic conditions, and was boosted when the soil redox changed from anoxic to oxic state. The results provide new insights into fate of TBP in soil and suggest the importance to evaluate the stability of NERs for risk assessment of TBP in soil.

Hundreds of new flame retardants (NFRs) are widely used, causing environmental pollution and threating human health. In this study, based on the interaction of NFRs and human serum albumin (HSA), we assessed the differences in potential human accumulation of 8 NFRs including 1,2-Dibromo-4-(1,2-dibromoethyl)cyclohexane (TBECH), tetrabromobisphenol A bis(dibromopropyl ether) (TBBPA-DBPE), 2,4,6-tribromophenol (TBP), pentabromophenol (PBP), tri-n-butyl phosphate (TnBP), triphenyl phosphate (TPP), Tri(2-chloroethyl) phosphate (TCEP), and Tri(1,3-dichloro-2-propyl) phosphate (TDCP). All NFRs could bind to HSA and cause slight damage to its structure, suggesting their potential human accumulation ability.

Enzymatic proteolysis is the key process to produce bioavailable nitrogen in natural terrestrial and aquatic ecosystems for microorganisms and plants. However, little is known on how protein degradation is influenced by organic contaminants. As we known, the overuse of organophosphate esters (OPEs) has caused serious pollution in soil, water, and sediment.

Thorium is a radionuclide used in various environmental studies such as dating, sediment movement, soil-plant transfer studies, and contamination of waste from the natural fuel cycle. The liquid-liquid extraction method using tri-n-butyl phosphate (TBP) allows for the separation of Th from the accompanying actinides. However, the separation of Th and U present in the same sample is not trivial.

Bromophenols has been proven to synthesize hydroxylated polybrominated diphenyl ethers (OH-PBDEs), which may pose additional environmental and health risks in the process of bioremediation. In this study, the removal of 2,4-dibromophenol (2,4-DBP) and 2,4,6-tribromophenol (2,4,6-TBP) and the biosynthetic of OH-PBDEs by Prorocentrum donghaiense were explored. The removal efficiencies of 2,4-DBP and 2,4,6-TBP ranged from 32.
