background: poly chlorinated biphenyls (pcbs) are the groups of organic chemical material and toxic, persistent, bio accumulate and pose a risk of causing adverse effects to human health and the environment. pcb compounds are caused the different health effects in human depending of age, sex, route of entry, intensity and frequency exposure. this study was conducted to determine the effect of m...

Soil salinity affects a large part of the region in Iran. Salinity covers 12.5% oftotal area of the country. Priming of seeds in sodium chloride and water (hydro-priming)has been reported to be a simple technique for enhancing the seedling establishment andgermination performance in the seeds of many crops and small seeded grasses under thestress conditions. Therefore, the aim of this research ...

background: pentachlorophenol (pcp) is one of the most fungicides and pesticides. acute and chronic poisoning from pcp may be occurred by dermal absorption, and respiration or ingestion. with respect to health and environmental effects of pcp, many methods were considered regarding its removal. microwave assisted other methods are environmental friendly, safety, and economical method, consequen...

A microwave-H2O2 process for sludge pretreatment exhibited high efficiencies of releasing organics, nitrogen, and phosphorus, but large quantities of H2O2 residues were detected. A uniform design method was thus employed in this study to further optimize H2O2 dosage by investigating effects of pH and H2O2 dosage on the amount of H2O2 residue and releases of organics, nitrogen, and phosphorus. A...

BACKGROUND H2O2 produced by vaginal lactobacilli is believed to protect against infection, and H2O2-producing lactobacilli inactivate pathogens in vitro in protein-free salt solution. However, cervicovaginal fluid (CVF) and semen have significant H2O2-blocking activity. METHODS We measured the H2O2 concentration of CVF and the H2O2-blocking activity of CVF and semen using fluorescence and in ...
