(Received: July 21, 2012; Accepted in Revised Form: July 5, 2013) Abstract: The principal concern of this study is to formulate the sub-pollution indices (sub-LPIs) and evaluate the individual and overall leachate pollutant index (LPI) of pilot scale landfill lysimeter at KUET campus, Bangladesh. To these endeavors, leachate samples from collection chamber of landfill lysimeter were sampling an...
This paper reports the pollutant removal efficiencies of two lab-scale hybrid wetland systems treating a textile wastewater. The two systems had identical configurations, each consisting of a vertical flow (VF) and a horizontal flow (HF) wetland that were filled with organic sugarcane bagasse and sylhet sand as the main media. The systems were operated under high hydraulic loading (HL) (566-566...
Extractions of a polycyclic aromatic hydrocarbon (PAH)-contaminated soil from a former manufactured gas plant site were performed with a Soxhlet apparatus (18 h), by pressurized liquid extraction (PLE) (50 min at 100 degrees C), supercritical fluid extraction (SFE) (1 h at 150 degrees C with pure CO2), and subcritical water (1 h at 250 degrees C, or 30 min at 300 degrees C). Although minor diff...
Twenty-eight ornamental species commonly used for interior plantscapes were screened for their ability to remove five volatile indoor pollutants: aromatic hydrocarbons (benzene and toluene), aliphatic hydrocarbon (octane), halogenated hydrocarbon [trichloroethylene (TCE)], and terpene (a-pinene). Individual plants were placed in 10.5-L gas-tight glass jars and exposed to ’10 ppm (31.9, 53.7, 37...
An analysis was made of residues of polychlorobyphenyls and trihalomethanes through GC-ECD and of herbicides through HPLC-PAD in samples proceeding from Navarra. Polychlorobyphenyls were detected (0.30 +/- 0.05 and 0.11 +/- 0.05 microg/l) in two of the 106 water samples analysed. Sixty-six food samples were analysed, and polychlorobyphenyls were only found in 8 samples of trout (dissimilar to d...
BACKGROUND The incidence of the insulin resistance syndrome has increased at an alarming rate worldwide, creating a serious challenge to public health care in the 21st century. Recently, epidemiological studies have associated the prevalence of type 2 diabetes with elevated body burdens of persistent organic pollutants (POPs). However, experimental evidence demonstrating a causal link between P...
We report the novel synthesis of nanoporous TiO2 nanoparticle ensembles with unique mesoscale morphologies. Constituent nanoparticles evolved into multifaceted assemblies, exhibiting excellent crystallinity and enhanced photocatalytic activity compared with commercial TiO2. Such materials could be exploited for applications, like organic pollutant degradation.
