In the context of climate change, diet is a key driver environmental impacts. Previous research has emphasized benefit increasing consumption fishery and aquaculture products (FAPs) in Europe. However, proportion FAPs consumer diets could also lead to transfer damage from earth sea. It thus important evaluate impacts on marine ecosystems globally. For that purpose, an original database characte...
It has been reported that bacteria-mediated degradation of contaminants is a practical and innocuous wastewater treatment. In addition, iron oxide nanoparticles (NP) are wastewater remediation agents with great potentials due to their strong adsorption capacity, chemical inertness and superparamagnetism. Therefore, a combination of NPs and microbes could produce a very desirable alternative to ...
Phycoremediation is the process of employing algae for removing excess nutrient load from wastewater and subsequently diminish the pollution load. It is an alternative technology of treating sewage wastewater compare to conventional treatment process in economical and sustainable way. Therefore, in the present investigation we had made an effort to phycoremediate the IARI’s sewage wastewater wi...
BACKGROUND In vitro cell testing of degradable bioceramics such as brushite or monetite is often challenging due to the ion release into or adsorption from the culture medium. These ionic changes are then mostly responsible for cell proliferation and activity, which prohibits the investigation of effects originating from surface topography or further material modifications. METHODS Here, we a...
Arsenic is a non-essential element that poses risks in many environments, including soil, groundwater, and surface water. Insights into the environmental biogeochemistry of As can be gained by comparing As and P reaction processes. Arsenic and P are chemical analogues, and it is proposed that they have similar chemical behaviors in environmental systems. However some chemical properties of As a...
dity increases the need to chlorinate drinking water, which, in -products that have been shown to increase the risk of cancer. The ry agencies based on issues of and aerated/unaerated mass fractions are identified reasingly being seen as tand the relevant factors which differentiate competing to recover nutrients as process, sewage treatment plant Phosphorus: Total phosphorus (TP) in domestic w...
سه سری نانوکامپوزیت مخلوط اکسید fe و si شامل fe2o3-sio2 با fe % wt 2 (1)، fe2o3-sio2 با fe % wt 35/4 (2) و fe2o3-sio2 با fe % wt 6/9 (3) با روش سل- ژل تهیه شدند و توسط آنالیز عنصری، طیف بینی ft-ir، xrd، bet و sem شناسایی شدند. این نانوکامپوزیت ها در اکسایش آلکن ها و الکل ها توسط هیدروژن پرکسید به عنوان اکسنده فعال بودند. اکسایش آلکن های خطی، حلقوی و آریل آلکن ها بررسی شد و درصد تبدیل در گستره ی...
Variation of hydrochemical conditions, with special reference to adequacy of waters as fish habitats, was traced based on selected hydrochemical parameters obtained during the studies conducted from February 2013 till February 2014 year. The results were compared with earlier studies. The sources of organic pollution were identified, and the effect of biogenic substances on the biomass, as well...
