introduction soil plays a vital role in human life as the very survival of mankind is tied to the preservation of soil productivity (kabata- pendies and mukherjee, 2007). the purpose of this study is the assessment of heavy metal contamination (zn, mn, pb, fe, ni, cr) of the soil around the khuzestan steel complex. materials and methods for this purpose, 13 surface soil samples (0-10 cm) were t...

Methyl tertiary butyl ether (MTBE)-A well known gasoline additive substituting for lead alkyls-causes lipid disorders and liver dysfunctions in animal models. However, whether MTBE exposure is a risk factor for non-alcoholic fatty liver disease (NAFLD) remains uncertain. We evaluate the possible relationship between MTBE exposure and the prevalence of NAFLD among 71 petrol station attendants in...

Background: The aim of this study was to measure137Cs levels in soil and brick samples to set the baseline data and an indicator of fallout radioactivity for this part of the world. This study will help to probe, if there is any health threat posed by 137Cs exposure to the residents of the area. Materials and Methods: Twenty five samples of soil and 6 samples of bricks were collected from diffe...

to find the nutritional condition of plants as related to the tatus of soil nutrients, also for an evaluation of soil solution toxicity and nutrition of plants in salt affected soils, it is preferred to study the activity of these elements rather than their concentrations. to calculate the ionic strength of a solution the concentrations of all cations and anions are needed which is very time co...

Access to point-of-care (POC), rapid, inexpensive, sensitive, and instrument-free tests for the diagnosis of tuberculosis (TB) remains a major challenge. Here, we report a simple and low-cost microchip-based TB ELISA (MTBE) platform for the detection of anti-mycobacterial IgG in plasma samples in less than 15 minutes. The MTBE employs a flow-less, magnet-actuated, bead-based ELISA for simultane...

cyanide (cn ) is a toxic species that is found predominantly in industrial effluents generated by metallurgical operations. cyanide’s strong affinity for metals makes it favorable as an agent for metal finishing and treatment and also as a lixiviate for metal leaching, particularly gold. these technologies are environmentally sound but require safeguards to prevent accidental spills from cont...

Methyl tert-butyl ether (MTBE) is a widespread groundwater contaminant that does not respond well to conventional treatment technologies. Growing evidence indicates that microbial communities indigenous to groundwater can degrade MTBE under aerobic and anaerobic conditions. Although pure cultures of microorganisms able to degrade or cometabolize MTBE have been reported, to date the specific org...

Plants are the most common bioindicatorsused in air quality biomonitoring studies because they are immobile and they have more sensitive to the most prevalent air pollutants than humans and animals. To identify the concentrations and sources of heavy metals in ornamental plants of Isfahan landscape, samples of leaves and soil around Pinuseldarica and Nerium oleander were collected at different ...
