BACKGROUND Residential natural gas cooking burners (NGCBs) can emit substantial quantities of pollutants, and they are typically used without venting range hoods. OBJECTIVE We quantified pollutant concentrations and occupant exposures resulting from NGCB use in California homes. METHODS A mass-balance model was applied to estimate time-dependent pollutant concentrations throughout homes in ...

Water use has been increasing globally by 1% per year, and recycling re-use are critical issues compromised the presence of pollutants. In this context, design novel materials and/or procedures for large scale-removal pollutants must be economically environmentally feasible in order to considered as part solution emerging economies. We demonstrate that cross-linking biodegradable polysaccharide...

The interaction between the ions and the charge of membranes can affect the efficiency of pollutant removal. The present study investigated the removal efficiency of hexavalent chromium and nitrate ions from both actual and synthetic contaminated water via two different commercial spiral wound polyamide nanofilters. In addition, the interaction of ions under different experimental conditions wa...

Introduction: Micro pollutants have become one of the most important environmental concerns around the world. These natural and synthetic compounds have been called Endocrine Disrupting Chemicals (EDCs) due to their interfere with the normal function of the endocrine system in humans and animals. They include natural and synthetic hormones and their metabolites, surfactant, insecticide, as well...
