Combinations of TiO2 photocatalysts and various adsorbents have been widely studied for the adsorption and photocatalytic decomposition of gaseous pollutants such as volatile organic compounds (VOCs). Herein, a TiO2-zeolite-porous glass composite was prepared using melt-quenching and partial sintering, hydrothermal treatment, and drop coating for preparation of the porous glass support and X-ze...

The environmental chemistry and ecotoxicology of persistent organic pollutants (POPs) are fascinating areas of scientific research. Our objective in this paper is to provide a brief, focussed overview of what constitutes a POP, highlight the harmful effects they may have on biota, make some comments on their environmental sources and analysis, their environmental trends and processes, their mov...

Physiologically Based Pharmacokinetic (PBPK) models can be used to determine the internal dose and strengthen exposure assessment. Many PBPK models are available, but they are not easily accessible for field use. The Agency for Toxic Substances and Disease Registry (ATSDR) has conducted translational research to develop a human PBPK model toolkit by recoding published PBPK models. This toolkit,...

Views on the entry of organic pollutants into matter (OM) decaying process are divergent, and in part poorly understood. To clarify these interactions, pesticide dissipation was monitored mineral soils not adapted to contaminants for 241 days; groundwater sediment slurries pesticides 399 their sterilized counterparts with without peat (5%) or compost-peat-sand (CPS, 15%) mixture addition. The r...

Background and aim Polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) per- polyfluoroalkyl substances (PFASs) are persistent organic pollutants (POPs) globally spread in environment with numerous toxicological properties, including thyroid endocrine disruption. We aimed to assess the associations between various POPs hormones among boys girls aged 12 years, accounting for pubert...

Zinc oxide nanoparticles (ZnO NPs) is unique studied semiconductor substance for photocatalytic utilization like light-emitting diodes, solar cells, photo-diode, sensor, and photo-detector. The ZnO ratio of surface to volume as increases with reduces size afford an increase improve the reactivity surface. Among all possible approaches preparation, sol-gel process individual simple synthesis met...
