Studies have shown that the lipophilic nature of polybrominated biphenyl (PBB) causes it to preferentially accumulate in breast milk posing a potential hazard for suckling infants. The purpose of this study was to examine the inter-generational transfer of PBB from mother to child and whether this association was modified by maternal breast-feeding patterns. One hundred and forty-five mother-ch...

This study was undertaken to investigate whether certain hazardous chemicals were present as components in new carpets, and if so, in what quantities. The study included analysis of eight new carpet samples that were available for retail in the UK. Some of the carpet samples contained high levels of organotins, in particular TBT (up to 47,500 ppb). One sample contained high levels (1600 ppb) of...

Polypropylene (PP) is a general-purpose plastic, but some applications are constrained by its high flammability. Thus, flame retardant PP is urgently demanded. In this article, intumescent flame retardant PP (IFRPP) composites with enhanced fire safety were prepared using 1-oxo-4-hydroxymethyl-2,6,7-trioxa-1-phosphabicyclo [2.2.2] octane (PEPA) functionalized graphene oxide (PGO) as synergist. ...

The presence of an emerging brominated flame retardant, decabromodiphenylethane (DBDPE), has been confirmed in Spanish sewage sludge. Thirty one samples from different urban wastewater treatment plants (WWTPs) were analyzed for this brominated flame retardant. DBDPE was positively identified and quantified in all samples at lower concentrations (47.0 +/- 29.7 ng/g dry weight (dw); mean +/- SD) ...

The thermal safety problem of lithium-ion batteries (LIB) in use requires an excellent management system to preserve it. In the paper, expansion flame-retardant composed APP and CFA kaolinite is used enhance property phase change materials (PCM). performances PCM their LIB were studied. results indicate that can improve long-term thermostability PCM. addition flame retardant make reach V0 level...

Flame-retardant polymeric coatings with high limiting oxygen index (LOI) were prepared by combining inorganic mineral huntite (H5) and additives synthesized in the present work into a formulation. In order to improve dispersion of Mg- (and Ca)-based H5 particles, containing phosphonium acidic groups employed homogenize fillers polymer matrix. Specific blend combinations commercial matrix Ecrovi...

magnesium hydroxide nanostructures as an effective flame retardant were synthesized by a facile and rapid microwave reaction. the effect of different surfactants such as cationic, anionic and polymeric on the morphology of magnesium hydroxide nanostructures was investigated. nanostructures were characterized by x-ray diffraction (xrd), scanning electron microscopy (sem) and fourier transform in...

In current years composites have concerned considerable importance as a potential operational material. Low cost, light weights, high specific modulus, renewability, and biodegradability are the most basic & common attractive features of composites that make them useful for industrial applications. Luffacylindrical locally called as “sponge-gourd” is one such natural resource whose potential as...
