Background and purpose: Considering the many benefits of fish in the food basket, it is essential to assess its health risk. The purpose of this study was to examine the risk assessment effects of heavy metals from Dez river fish. Materials and Methods: In order to determine the concentration of heavy metals in the edible parts of fish, 80 samples were caught from the local species of Dez Rive...

Background: Some metals play an important role in  biological reactions  and metabolism of human body. Low and high concentrations of these elements can cause diseases and poisoning. This study was carried out in order to investigate the concentration of metals in inlet and outlet water of households in Ahvaz city, Iran in 2018. Materials and Methods: This was a cross-sectional descriptive stud...

Background and purpose: In recent years, dust storms have affected many regions in Iran including Kurdistan province. Along with dust other pollutants such as heavy metals may also be transferred which pose a risk to human health. The purpose of this study was to determine heavy metals concentrations in atmospheric PM10 in Sanandaj, Iran and also assessing their health risk on the staff and stu...

Background and Purpose: In the environment, heavy metals in high concentration are toxic to most organisms. Human activities have continuously increased the concentration of these metals in the environment such as soils. In the present study, soil samples collected from Ahvaz IV industrial estate in Khuzestan Province. Materials and Methods: The soil samples were taken from 9 ...

High concentrations of heavy metals in street dust are considered to be a serious risk to the human health and the environment. In this study, 30 dust samples were collected from the pavements in the main streets of Abadan to determine the level of pollution of heavy metals in the street dust. Heavy metal concentrations were analyzed by inductively coupled spectroscopy (ICP-OES) method. The lev...

The aim of this study was to investigate acute toxicity (96-hr LC50 and lethal concentrations) of waterborne metal mixture (Pb+Mn) for the fish, Catla catla, Labeo rohita, Cirrhina mrigala, Ctenopharyngodon idella and Hypophthalmichthys molitrix. The extent of metals bio- accumulation in fish body organs viz. gills, liver, kidney, fins, bones, muscle and skin at both 96-hr LC50 and lethal conce...

Polycyclic aromatic hydrocarbons (PAHs), abundant in mixed contaminant sites, often coexist with heavy metals. The fate and remediation of PAHs depend heavily on the sorption and desorption behavior of these contaminants. The sorption behavior can in turn be highly affected by certain soil components and properties, such as soil organic matter (SOM) and the presence of heavy metals. Through rev...

Background & Aims of the Study: Rhodococci according to possess large genome, their active metabolism and survival under extreme conditions, are highly regarded for biodegradation and bioremediation of different pollutants especially heavy metals in the environment. Biofilms are more resistant to heavy metals than free-swimming organisms. The aim of this study was biofilm forma...
