The main goal of this study was to analyze the psychometric properties of the Perception of Parents Scale (POPS) developed by Robbins (1994), with a sample of middle-adolescents with ages between 14 and 18 years. The confirmatory factor analysis was conducted to examine the reliability and validity of a three-dimension model of adolescents’ perception of mother and father based on perspective o...

During the past two decades, the rapid development of the Pearl River delta leads to substantial accumulation of various toxic organic compounds. This study aims to give a preliminary characterization of the existing state of contamination in this region and to provide insight into the possible fate of persistent organic pollutants (POPs) in this estuary. The available data on POPs in water, ri...

To monitor environmental pollutants in Faroese biota, samples from a top predator were analysed and put into a spatial and temporal context. Analysis of 20 Great Skua eggs sampled in 2012 from the Faroe Islands showed >70 % lower concentrations of legacy persistent organic pollutants (POPs) than in samples analysed in 1977. The 2012 Faroese eggs showed higher concentrations than for eggs in She...

Balloon pops are convenient for probing the acoustics of a space, as they generate relatively uniform radiation patterns and consistent “N-wave” waveforms. However, the N-wave spectrum contains nulls which impart an undesired comb-filter-like quality when the recorded balloon pop is convolved with audio. Here, a method for converting recorded balloon pops into full audio bandwidth impulse respo...

Several recent studies have shown that n-octanol/water partition coefficients may not be a good predictor for estimating soil sorption coefficients of persistent organic pollutants (POPs), defined here as chemicals with log Kow greater than 5. Thus, an alternative QSAR model was developed that seems to provide reliable estimates for the soil sorption coefficients of persistent organic pollutant...

Due to growing concerns regarding persistent organic pollutants (POPs) in the environment, extensive studies and monitoring programs have been carried out in the last two decades to determine their concentrations in water, sediment, and more recently, in biota. An extensive review and analysis of the existing literature shows that whilst the vast majority of these efforts either attempt to comp...

Robust catechol-functionalized porous organic polymers (POPs) with tunable porosities (560−1050 m/g) and degrees of functionalization were synthesized using a cobaltcatalyzed acetylene trimerization (CCAT) strategy. Post-synthesis metalation can be readily carried out with a wide range of metal precursors (Cu, Mg, and Mn salts and complexes), resulting in metalated POPs with enhanced heat of hy...

Persistent organic pollutants (POPs) in various food supplies have important health impacts, but are not as devastating as malnutrition and, perhaps, obesity. POPs should be controlled and the Stockholm Convention is having an accelerating effect on the global decline of POP manufacture and use. Reservoirs from previous misuses are much larger than current manufacture and efforts should be dire...

With recent advances in biomolecular engineering, the bioremediation of persistent organic pollutants (POPs) using genetically modified microorganisms has become a rapidly growing area of research for environmental protection. Two main biomolecular approaches, rational design and directed evolution, have been developed to engineer enhanced microorganisms and enzymes for the biodegradation of PO...
