Millions of Muslims fast during the month of Ramadan and avoid eating and drinking during this month (1). Fasting is a healthy and non-pharmacological way to improve your health and weight loss (2, 3). During fasting days, nutritional patterns and the amount of food consumed will change (4). It can be concluded that these changes can lead to changes in the metabolism of the human body. The purp...

to determine the extent and the size of the environment pollution with heavy metals, biologicalmethods, investigating the enzymatic activity of soil can be applied. most frequently, the enzymes investigated in the soils threatened with anthropogenic contamination are phosphatases, dehydrogenases as reacting fastest to the increase in the content of heavy metals in the environment. the aim of th...

A large fraction of the trace metal pool in estuarine and coastal waters is complexed with colloidal-sized macromolecular organic matter. Bioaccumulation and bioavailability studies of trace metals have generally utilized freeionic dissolved metal ions. Consequently, little is known about the uptake and depuration kinetics of the colloidally bound species. Chemical characteristics such as the r...

Total-reflection X-ray fluorescence (TXRF) has achieved remarkable success with the advantages of simultaneous multi-element analysis capability, decreased background noise, no matrix effects, wide dynamic range, ease of operation, and potential of trace analysis. Simultaneous quantitative online analysis of trace heavy metals is urgently required by dynamic environmental monitoring and managem...

This study was conducted to determine the concentration of five heavy metals, including lead, cadmium, mercury, arsenic, and chromium in muscle, liver and gills of the gray mullet, Liza aurata in southern part of the Caspian Sea. The samples were collected during sexual maturity (in the fall) and sexual rest (in the spring). The mean concentration of lead, cadmium, mercury, arsenic, and chromiu...
