The interaction mechanisms of co-existing polybrominated diphenyl ethers and engineered nanoparticles in environmental waters: A critical review.

This review focuses on the occurrence and interactions of engineered nanoparticles (ENPs) and brominated flame retardants (BFRs) such as polybrominated diphenyl ethers (PBDEs) in water systems and the generation of highly complex compounds in the environment. The release of ENPs and BFRs (e.g.

Application of infrared spectrum for rapid classification of dominant petroleum hydrocarbon fractions for contaminated site assessment.

In this study, the infrared spectrum (4000-400 cm) was applied to identify and classify the different alkanes based on carbon chain length (C). It was found there were two bands coherent to the doublet at location 2954 and 2872 cm, respectively can be applied to identify the fraction of carbon chains. From C to C, by the increase of the C, the intensities of the two bands were reduced as demonstrated.
