the removal of organic precursors of disinfection by-products (dbps), i.e. natural organic matter (nom), prior to disinfection is considered as the most effective approach to minimise the formation of dbps. trihalomethanes (thms) as the main group of dbps are categorized and considered to have the potentiality of increasing the rate of liver, kidney and cns adverse effects. this study which pre...

Total organic carbon has a major influence on both the chemical and biological processesthat take place in sediments. Algal bloom is one of the organic carbon levels in aquatic ecosystems. In 2009 algal bloom occurred in the Hormozgan province and prolonged for months, which finally setteled down in 2010. In this study the variations of total organic carbon (TOC), organic matter (TOM) and tot...

Organic carbon pools and carbon lability directly affect soil biological, physical and chemical characteristics. Besides, capacity of self-organization of soil is related to the organic carbon pools. Sand size fraction (> 50 µm) organic matter is more labile than silt+clay size fraction organic matter. Assessment of this organic carbon variation can be a suitable index to determine soil quality...
