risk-based assessment methods are commonly used at the contaminated sites by hydrocarbon pollutants. this paper presents the results of a two-dimensional finite volume model of reactive transport of biodegradable btex which have been developed for the saturated zone of an unconfined aquifer in the pump station area of tehran oil refinery, iran. the model governing equations were numerically sol...

background: the criteria for the quality control of iranian fresh produce are the total microbial count, enterococcal count and the detection of escherichia coli. the aim of this study was to assess microbial contamination of fresh vegetable and salad samples consumed in tehran, iran. methods: from may to october 2013, freshly vegetable (n=100) and salads (n=100) samples were randomly collected...

Surveillance and Control of air quality in an industrial site close to urban areas in Arganda del Rey (Madrid), by means of a flexible, open and configurable net. * SURVEILLANCE AND MESSAGES DECISION: Through a set of local units distributed at the industrial site that process sensor signals following a user protocol and make decisions on: 1) signals acquisition and 2) alarm messages transmissi...

Deep-sea sediments enriched in rare-earth elements and yttrium (REY) plus scandium (Sc), termed “REY-rich mud,” have attracted attention as a possible resource for these critical industrial elements. Examples been reported from the western North Pacific, central low-latitude South eastern Pacific. Although previous studies of pelagic clay existence highly REY-rich mud ultraoligotrophic Pacific ...

in this research by taking advantage of degradtion model ina grid system an area of 9222 km in eastern part of tehran province including eslam shahr , rey , varamin , damavand , and firooz kooh were studied . the results show that 43.8 % of the area , due to its natural condition , is not suitable for development. the rest of the area ( 42.5) due to the degradation caused by man's activiti...

The geochemistry of rare earth elements and yttrium (REY) in phosphorite has been widely studied. However, the effect organic matter on REY enrichment not well determined. We utilized paired inorganic (δ13Ccarb) carbon isotopes, total (TOC), content (∑REY) Zhijin Motianchong (MTC) compared them with those Meishucun (MSC) to reveal REY. δ13Ccarb MTC area (≈0‰) is heavier than that MSC (−5.23‰ −1...
