“…Furthermore, during metabolism and in the environment, through a process of reductive debromination, congeners of higher molecular weight, such as BDE-99 and BDE-100, can form BDE-47. Similarly, BDE-154 can generate BDE-99 and BDE-100, and BDE-153 can form BDE-99, and consequently also may form the BDE-47 [ 25 , 32 , 36 , 37 , 38 ]. Among the other congeners analyzed, the BDE-28, BDE-99, and BDE-183 also showed higher detection rates, corresponding to 47%, 43%, and 35%, respectively.…”

“…The study reported by Cui et al (2012) [ 33 ] also showed a positive correlation between the higher concentrations of PBDEs determined in Chinese breast milk with high school education levels and family monthly salary. It is important to consider that diet is one the most relevant source of PBDEs exposure for adults, especially food with high lipid content, such as animal-origin food [ 29 , 32 , 39 , 41 , 42 ]. Besides, contact with electronic products and other consumer products containing PBDEs, and dust ingestion may also be considered an important exposure source for the population.…”

“…This biomonitoring study evaluated the concentrations of ∑tri to hepta-BDE in Brazilian breast milk samples. The analytical method was based on reported studies by Souza et al (2021) [ 32 ], with adaptations. Initially, lyophilized breast milk samples were spiked with 20 µL of internal standard and extracted with 2 mL of hexane.…”

Polybrominated diphenyl ethers (PBDEs) are ubiquitous flame retardants and are environmentally persistent. PBDEs show endocrine disruption, neurotoxicity, and lower birth weight in infants, and their human body burden has become a public health concern. The infants’ exposure begins in the prenatal period and continues via breast milk ingestion, although, little is known about the factors that may influence this exposure. In this study, PBDE levels in Brazilian breast milk were assessed in 200 lactating women. The risk assessment of infants’ exposure to PBDE was performed through the estimated daily intake (EDI) calculation. The geometric mean (GM) of ∑PBDEs levels was 2.33 (0.14–6.05) ng/g wet weight. At least one PBDE congener was detected in the samples, and the 2,2′,4,4′-tetrabromodiphenyl ether (BDE-47) showed a 100% of detection rate (GM of 1.05 ng/g). Location of residence, maternal level education, monthly salary, and race were positively associated with PBDE levels (p < 0.05). The EDI of BDE-47 was higher in Belo Horizonte (8.29 ng/kg/day) than in Viçosa (6.36 ng/kg/day), as well as for the ∑PBDEs (19.77 versus 12.78 ng/kg/day) (p < 0.05). Taking the high detection rate of PBDEs in breast milk and their toxicity, continuous studies on infant exposure, fetal growth, and child neurodevelopment are requested.

“…Adding flame retardants to WPCs during processing is the primary method to enhance the fire-safety performance of WPCs. Among the flame retardants, the use of halogen flame retardants has been banned because of their harmful effects to the environment and the release of toxic gases during combustion. − Although the high contents of inorganic flame retardants, such as Al(OH) 3 and Mg(OH) 2 , enhance the flame retardancy, they usually affect the mechanical properties of WPCs adversely. − For comparison, phosphorus-containing flame retardants have excellent flame-retardant properties. Ammonium polyphosphate (APP), as a commercial flame retardant, has excellent effects when it is combined with synergists, such as expanded graphite, layered double hydroxide, new triazine polymers, and nano-silicon dioxide .…”

Using bio-based chemicals and recycling waste plastics are essential components of the circular economy. Wood−plastic composites (WPCs), fabricated from recycled plastic and wood-processing wastes, are new, green, and environmentally friendly materials. However, their flammability causes potential fire risks and hazards. Although bio-based flame retardants possess the essential advantage over inorganic or petroleum-based chemicals, their application, particularly that of fully bio-based flame retardants, in WPC has been seldom reported. Herein, we designed and synthesized a fully bio-based flame retardant, phytic acid-tyramine salt (referred to as PATA), using a green and environmentally friendly approach with only deionized water as the reaction solvent. PATA is subsequently utilized in conjunction with ammonium polyphosphate (APP) to synergistically impart flame-retardant properties to WPCs. PATA/APP shows a good flame-retardant effect, improving the flame retardant and smoke suppression properties of WPCs. The PATA/APP system can increase the limiting oxygen index by 31% and achieve a vertical combustion V-0 rating. Furthermore, the PATA/APP system can reduce the peak heat release rate, total heat release, and maximum smoke density by 49, 22, and 15%, respectively. The PATA/APP system can generate phosphoric acid substances during combustion, which promote the decomposition of wood flour to form stable char layers containing P−N−C or P−O−C structures. Consequently, we provide an environmental-friendly approach to enhance the flame retardancy of WPCs.
