background facultative marine fungi could potentially be arsenic tolerant and may be able to remove this highly poisonous metal from the environment. objectives the objective of this work was to explore the degree of tolerance and removal efficiency of two facultative marine fungi. materials and methods facultative marine fungi aspergillus flavus and rhizopus spp. were exposed to 25 mg/l and 50...

Heavy metals are regarded as toxic trace elements in the environment. Heavy metal pollution in soil or rice grains is of increasing concern. In this study, 101 pairs of soil and rice samples were collected from the major rice-producing areas along the Yangtze River in China. The soil properties and heavy metal (i.e., Cd, Hg, Pb and Cr) concentrations in the soil and rice grains were analyzed to...

A number of review articles have appeared in the literature recently on metal accumulation by plants. However, reports on the tolerance, accumulation and detoxification of arsenic in plants, especially in terrestrial plants, are limited. In light of the strong needs for study of arsenic biogeochemistry and development of arsenic decontamination techniques, in this paper we. review arsenic uptak...

The current study assesses the effect of fibrous clay minerals’ amendments and arbuscular mycorrhiza incubation on heavy metal uptake and translocation in Eucalyptus grandis and Ailanthus altissima plants. For doing so, Eucalyptus and ailanthus trees have been grown in a soil sample, contaminated with heavy metal iron ore mining and collected from southern Iran. The area under study is arid, wi...

The present investigation assessed the effects of a metalloid (arsenic) and two heavy metals (cadmium and mercury), on the growth and metal accumulation in two medicinal plant species, artichoke (Cynara scolymus L.) and Savory (Satureja hortensis L.). The experiment was conducted hydroponically in spiked solution with different concentrations of arsenic (0, 20, 100, and 500 µM), cadmium (0, 10,...

Rapid industrialization along with advanced agricultural activities led to the contamination in aquatic environment with heavy metals. Heavy metals ultimately pass into human body through having aquatic animals like fish, prawn and crab. In this study, accumulation of heavy metals (zinc, copper, iron, cadmium and lead) in various organs of four commonly consumed fish (Euthynnus affinis...
