Concentrations of Ni, V, Pb and Cu were determined in bottom sediments and liver, gills and fillet of Euryglossa orientalis and Chirocentrus nudus along the Bahrekan Bay in the Northwest part of the Persian Gulf in Iran. Sediment samples and fish species were collected during winter 2013 and spring 2014. Heavy metal analysis was performed by atomic absorption spectrophotometer. Results showed t...

atomic number above 20. These properties are not the world. In India it is cultivated under 83.00 ha of relevant for biological effects, yet the heavy metals land with production of 7.9 lakh metric tonnes. Keeping enclose essential nutrients, beneficial elements and these points in view the present investigation has been elements which, at the present stage of knowledge, are made to study the e...

some heavy metals are dangerous to health and there is rising concern about the quality of foodstuffs in some parts of the world. fish, particularly tuna fish, can concentrate huge quantities of several metals from water and they even play a significant role in human nourishment. objectives: in this study, the concentrations of mercury and four trace metals in five brands of canned tuna samples...

A large proportion of the world’s population relies on medicines from the herbal sources. In this review, data about the mineral element content of medicinal and aromatic plants, including major elements, trace elements and toxic heavy metals, will be discussed and compared. Plants and drugs with remarkable elemental compositions will be pointed out. The main focus will be given on plants used ...

background & aims of the study: vegetables and cereals are considered vital for properly-balanced diet given that they deliver vitamins, minerals, nutritional fiber, and phytochemicals. this study aimed to assess the concentration of as, cu, cd, pb, cr and hg in common vegetables and cereals in urban open markets in varanasi district, india materials & methods: total 260 edible portions of vege...

Background & objectives: Since many plants have high efficiency in absorbing heavy elements, the use of phytoremediation is of great importance. The purpose of this study is to identify native plants that absorb heavy metals. Also, the possibility of using them in phytoremediation technology in soils contaminated with heavy metals (around the petrochemical industry of Razi fertilizer in Tehran ...

INTRODUCTION The role of trace metals elements in human nutrition can no longer be ignored. Deficiency caused by inadequate dietary intake, secondary deficiencies often under - estimated, and iatrogenic deficiencies lead to pathologies such as infections and others. For this reason their dosages are particularly important to assess disease severity and to facilitate early treatment or improve p...
