[ 1 ] - بررسی آلودگی و منشأ فلزات سنگین و هیدروکربن های آروماتیک چندحلقه ای (PAHs) در رسوبات سطحی رودخانه قره سو شهرستان کرمانشاه

ویژگی‌های فیزیکوشیمیایی، و آلودگی فلزات سنگین (Cu, Pb, Zn, Fe, Al, V, Ni) و ترکیبات PAH در رسوبات رودخانه قره‌سو کرمانشاه مطالعه شد. نتایج شاخص آلودگی (CF)، شاخص بار آلودگی (PLI) و ضریب غنی‌شدگی بیانگر آلودگی شدید رسوبات به ویژه درمورد عناصر سرب، روی و مس در مقاطعی از رودخانه بود. همچنین ایستگاه‌های نزدیک به شهر کرمانشاه مانند پالایشگاه نفت و شهرک صنعتی آلودگی بسیار بالاتری از PAH نسبت به بالا ...

[ 2 ] - Evaluation of heavy metals concentration in surface sediments of the Mordab river and parts of the Caspian Sea coast in Astara county

Background and Objective: Due to the importance of Mordab river, the concentration and distribution of heavy metals in sediments and part of Caspian sea coast, mostly affected by the Mordab river, were evaluated. Additionally, considering the possibility of heavy metals release from sediments to water column and transfer to crops, the health risk of rice consumption in the region was assessed. ...

[ 3 ] - Study of heavy metals in bottom sediments of Mahabad river and dam, and investigating the risk of consumption of edible fish in the area

Background and Objective: Heavy metals contamination, particularly in aquatic environments, is an important concern.  Since Mahbad river is the source for supplying drinking water to the city and the dam established on it is used for catching fish and sale in the market, heavy metals concentrations in the sediments of Mahabad River and the Dam, and the possible health risk of the fish consumpti...

[ 4 ] - Investigating abundance and characteristics of microplastics as emerging pollutants in sediments of Taleqan dam and upstream river in Alborz province

Background and Objective: Microplastics (MPs) pollution are considered as a major growing global environmental problem in the past few decades. Dams could be an important reservoir for microplastics accumulation, therefore, in this study the presence of microplastics in sediments of Taleqan Dam and its upstream river was investigated in order to: 1) determine the local status of microplastic po...

[ 5 ] - Study of contamination, sources and health risk of potentially toxic elements in dusts of Tehran’s elementary schools

Concerns about dust contamination with potentially toxic elements are especially important in environments such as schools (particularly elementary schools) because children are more vulnerable to contaminants than adults. Therefore, due to the diversity of air pollution sources in Tehran, the present study was conducted to determine the severity of pollution, origin and health risk assessment ...
