research topics dealing with the application of the markal model have been quite common in the last 20+ years. every new paper has added new insight into the potential of using such a model for a variety of purposes. not only global but also local applications have shown both limits and benefits when dealing with manifold energy-environmental-resources optimal management. the aim of this wo...
Objective: The major Fusarium toxins found in cereals and cereal-based products that can be harmful to both human and animal health are some trichothecenes, such as deoxynivalenol (DON). Methods: A recent SCOOP project, Since toxinogenic fungi are cosmopolitan, mycotoxins are environmental pollutants present in virtually all parts of the world and causing diseases (mycotoxicoses) . Thi...
Background and Objective: Application of chemical fertilizers in agricultural industry is known as one of the methods of crop enhancement. However, chemical fertilizers application can lead to an increased risk of chemical pollutants entering the human food cycle. The aim of current research was feasibility study and evaluation of nickel from paddy soils in Lorestan province. Materials and Me...

The Environmental Protection Act has created a growing need for the measurement and assessment of trace emissions to the environment. This encompasses three main areas of ground, water and the atmosphere. The need to achieve lower emissions has placed a large burden on analytical techniques, particularly in the areas of trace analysis to ppb and ppt levels. Chromatographic techniques are widely...
alfalfa and maize are important agricultural plants for animal consumption. in this survey, accumulation quantity of heavy metals (fe,zn,mn,cd,pb,ni,cr) in plants irrigated by sewage and well water were compared statistically together and with normal or standard(permeable) limits in plants or foraging, during 2005. the results were as following 1-maize: the value of accumulation in maize irriga...
the present study has been undertaken in a laboratory scale to characterize and investigate pollution potential of textile effluents from depz area in dhaka, bangladesh. collected effluent samples from five different industries were analyzed for physico-chemical parameters using field kits and standard methods, and for metals using flame atomic absorption spectrophotometer (faas). the average p...
the present study aimed at investigating and estimating the amount of damage caused by waste water pollution of water desalinators in the south pars special zone. the main reasons for conducting this study were to investigate the creation of environmental pollutants as a result of the development and expansion of different industries in the south pars zone, as well as the ecological sensitivity...
