In the present study, to evaluate the oxidation quality of fish meal stored at refrigerator temperature for 6 months, a colorimetric nano-sensor aminated graphene oxide - bromophenol blue based on Whatman paper was used. The results showed that the amount of moisture increased from 7.19% to 9.37% and ash content increased from 7.29% to 8.04% during storage (P <0.05). The amount of changing in fat and protein contents showed that fat content decreased from 12.87% to 10.53% and protein content decreased from 54.51% to 52.37% and showed decrease procedure during the storage period (P <0.05). Peroxide value (PV) increased during the period, and the maximum amount of that was at the end of the storage period with 6.1 meq O2 / kg lipid (P <0.05).

The role of slope aspect in erodibility of Ghachsaran and Aghajari formationsExtended Abstract Introduction:The erodibility of watershed area is a function of several factor, one of these factors is topography. Including main topography features is slope aspect of which directly or with the effect on other environmental factors is caused changes in soil hydrological processes particularly the potential for runoff and sediment production. Soil erosion is the most important environmental factor in the world that adversely affects all-natural ecosystems as well as those under human management. Although soil erosion has existed throughout history, it has been intensified in recent years due to improper land use. Environmental factors, such as

Human exposure to mercury (Hg) mainly occurs through consumption of aquatics, especially fish. In aquatic systems, the bioaccumulation of Hg across trophic levels could be altered by invasive species through changing community composition. The present study is aimed at measuring total mercury (T-Hg) and methylmercury (MeHg) concentrations in non-native (redbelly tilapia (Tilapia zillii)) and native (Benni (Mesopotamichthys sharpeyi) and common carp (Cyprinus carpio)) fish species throughout Shadegan International Wetland and comparing health risk of their mercury contents to the local population. The concentrations were measured using a direct mercury analyzer (DMA 80). The average values of T-Hg and MeHg for native fishes were 19.8 and 10.

Mercury (Hg) is one of the water pollutants and its removal from the aqueous environment is important. The major goal of this study was to remove the Hg (II) from aqueous solution by synthesizing a modified nanochitosan with carbon disulfide functional groups. Nanochitosan was synthesized using citric acid as an environmentally friendly crosslinking agent, and then it was modified with a carbon disulfide functional group. The characteristics of synthesized nanocomposite were studied by using proton nuclear magnetic resonance (1HNMR), transmission electron microscopy (TEM), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR). Batch adsorption experiments of Hg (II) in metal ion solution were conducted under

Nickel (Ni) as a heavy metal due to its toxicity should be removed from wastewater and aquatic environments using efficient technology. The aim of this study was to remove Ni from an aqueous solution using palm leaf ash produced in a furnace. To do so, kinetic and thermodynamic experiments were conducted on the adsorption process. Moreover, the effect of time, pH, adsorbent and initial concentration of Ni was studied on Ni adsorption. The results of the experiment indicated that the Ni adsorption process followed the Freundlich isotherm model. The study of kinetic data also displayed the removal of Ni ions from the pseudo-second-order kinetics. The results showed that the percentage removal of Ni (II) and maximum adsorption capacity of an a

Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous pollutants in the urban atmosphere. An investigation of PAHs in the urban atmosphere of Tehran, Iran, was conducted in this study. Car engine air filters (CAFs) were collected in 15 taxi garages between 2016 and 2017 and analyzed for PAHs to assess the concentration level and health risks of polycyclic aromatic hydrocarbons (PAHs). The total concentrations of 16 PAHs (ΣPAHs) ranged from 169 to 174 μg/CAF. The average ΣPAHs concentration in winter was slightly higher than in summer. The most abundant individual PAH was phenanthrene, followed by fluoranthene, pyrene, and naphthalene. Concentrations of benzo [a] pyrene (BaP) varied between 1.80 and 2.27 μg/CAF. Based on estimated air v
