The state of works of art exhibited inside museums can be strongly influenced by indoor air quality, due to chemical activity of gaseous pollutants and particulate matter. For that reason it is important to carry out ...

Under the contemporary scenario of global climate change and increasing coastal eutrophication, baseline studies of phytoplankton diversity and distribution in relation to habitat conditions constitute the first approach ...

Fragmentation, or breaking apart of habitats, is one of the major causes of decline in biological diversity. Mature ecosystems, especially dense forests are very sensitive to this phenomenon and roads are one of the major ...

Degradation of O,O-dimethyl -O-4-nitrophenylphosphorothioate (methylparathion) by ozonation in aqueous solution was studied in a batch reactor under constant ozone dosage and variable pH conditions. The effectiveness of ...

Environmental pollution by 2,4-dicholorphenol (2,4-DCP), commonly found in industrial wastewater has been a concern for humans over the past 50 years. Garden Radish Peroxidase (GRP) can eliminate this poisonous pollutant. ...

It is very important to determine the stable nitrogen isotope ratio for the nitrogenous substances in aerosols and the geochemistry behavior of stable nitrate ion isotopes in aerosols in order to elucidate the chemical ...

Protein-rich hydrolysate from feather waste was obtained using a mixed culture of selected thermophilic actinomycete strains, and was tested for possible application as soil amendment and biological control agent. For ...

Tehran has a population of over 12 million and produces more than 7500 tons of waste every day. Tehran's municipal solid waste is processed and landfilled at Kahrizak disposal center. Due to inappropriate waste ...

This study aims to quantify the impacts of land use changes on ecosystem service value during large scale land development, and to provide key information for both economic development and policy makers for eco-environmental ...

Enzymatic extract preparation from Pseudomonas aeruginosa KM110 under accession No. HQ730879 with lipase activity (0.3 U/ml), was used to perform enzymatic hydrolysis pretreatment of a synthetic dairy wastewater with 1000 ...

Oil pollutions are widespread environmental pollutants. Most of the studies have been focused on the biodegradation of these pollutions. Unfortunately, the information on the microflore of the polluted regions especially ...

The current research was carried out with the aim of the investigation of organizational learning dimensions role in the development of enviropreneurship in environmental Non-governmental organizations (NGOs) in Iran by ...

Identification of rapid degradation of ecological resources requires effective environmental monitoring including ecological integrity assessment .Our first aim is to analyze ecological integrity in a landscape context ...

This study investigated maturation and stability levels during composting of Quercus robur (QR) woodchips mixed with different nitrogen sources (horse manure, HM and lake mud, LM) for potential agronomic utilisation. The ...

The oil refining industries are using a number of demulsifiers for dewatering and desalination of crude oil but experience has shown that universal demulsifiers can not be produced. Each kind of water in oil (W/O) emulsion ...

Environmental contamination by toxic metals is a serious problem due to their extreme toxicity towards aquatic life and humans. Biosorption is an alternative technology to conventional processes for the removal of metals. ...

Adsorption of anilofos was studied in four soils (topsoil from alfisol, inceptisol, oxisol and vertisol). The order of adsorption of anilofos was Vertisol > Oxisol > Alfisol > Inceptisol. The soil sorption coefficient K ...

The main factors affecting environmental sensitivity to degradation are soil, vegetation, climate and management, through either their intrinsic characteristics or by their interaction on the landscape. Different levels ...

The present investigation provides a thorough study of eliminating soluble and colloidal elements of copper, iron, magnesium and zinc during estuarine mixing of Gorganrood River water with Caspian Sea water in Iran. The ...

The effect of salinity on organic removal and ammonium oxidation in a down-flow hanging sponge reactor was investigated by conducting a long-term continuous experiment over a period of 800 days. The DHS reactor, constructed ...
