“…The risks posed by radionuclides in water have attracted considerable attention since the Fukushima Daiichi Nuclear Power Plant in Japan was damaged by an earthquake [1]. Radioactive fallout from nuclear plants and the nuclear industry can cause great damage to human health upon entering the environment [2,3]. Radiocesium ( 137 Cs) is a commonly studied fission product that presents serious concern because of its long half-life of 30 years and ready dissolution in water [4].…”

Many efforts have focused on the adsorption of metals from contaminated water by microbes. Synechococcus PCC7002, a major marine cyanobacteria, is widely applied to remove metals from the ocean’s photic zone. However, its ability to adsorb cesium (Cs) nuclides has received little attention. In this study, the biosorption behavior of Cs(I) from ultrapure distilled water by living Synechococcus PCC7002 was investigated based on kinetic and isotherm studies, and the biosorption mechanism was characterized by Fourier-transform infrared spectroscopy, Raman spectroscopy, scanning electron microscopy, transmission electron microscopy, energy-dispersive X-ray spectrometry, and three-dimensional excitation emission matrix fluorescence spectroscopy. Synechococcus PCC7002 showed extremely high tolerance to Cs ions and its minimal inhibitory concentration was 8.6 g/L. Extracellular polymeric substances (EPS) in Synechococcus PCC7002 played a vital role in this tolerance. The biosorption of Cs by Synechococcus PCC7002 conformed to a Freundlich-type isotherm model and pseudo-second-order kinetics. The binding of Cs(I) was primarily attributed to the extracellular proteins in EPS, with the amino, hydroxyl, and phosphate groups on the cell walls contributing to Cs adsorption. The biosorption of Cs involved two mechanisms: Passive adsorption on the cell surface at low Cs concentrations and active intracellular adsorption at high Cs concentrations. The results demonstrate that the behavior and mechanism of Cs adsorption by Synechococcus PCC7002 differ based on the Cs ions concentration.

The aim of this work was to evaluate the utility of Azolla filiculoides growing in a hydroponic system for the phytoremediation of continental water polluted with cadmium and copper during 7 days of exposure. Cadmium and copper chloride were added to the medium at concentrations of 0.5–10 mg/L and 0.1–25 mg/L, respectively. Cadmium and copper levels were measured in each plant using flame atomic absorption spectrophotometry. The analytical methodology used to measure cadmium and copper levels was validated with standard reference material (SRM) – 1570 (spinach) National Institute of Standards and Technology. The results indicated that cadmium and copper phytoremediation was statistically significant with a maximum increase in plant tissue of 1623.20 and 6013.1 μg/g, respectively. This photosynthetic efficiency was chronically damaged when Azolla filiculoides were exposed to 10 mg/L of Cd and 25 mg/L of Cu. The Azolla plants were not affected in the other phytoremediation treatments with copper.

“…Furthermore, this method can be used for analyzing many biological materials, including saliva, hair, blood serum, cells, and animal and plant tissues (Govil, 2001;Mulware, 2013). From this point of view, this technique allows studying the distribution of chemical elements in different medical and biological fields of study (Alatise et al, 2010;Bellis et al, 2009;Carmona et al, 2010;Ghorbanzadeh Mashkani and Mohammad Ghazvini, 2009;Gowrishankar et al, 2010;Kro sniak et al, 2013;Lyubenova et al, 2012;Olsson et al, 2011;Saha et al, 2010;Tanaka et al, 2010;Ugarte et al, 2012):…”

The aim of this article is to describe selected analytical techniques and their applications in the quantitative mapping/(bio)imaging of metals in biological samples. This work presents the advantages and disadvantages as well as the appropriate methods of scope for research. Distribution of metals in biological samples is currently one of the most important issues in physiology, toxicology, pharmacology, and other disciplines where functional information about the distribution of metals is essential. This issue is a subject of research in (bio)imaging/mapping studies, which use a variety of analytical techniques for the identification and determination of metallic elements. Increased interest in analytical techniques enabling the (bio)imaging of metals in a variety of biological material has been observed more recently. Measuring the distribution of trace metals in tissues after a drug dose or ingestion of poison-containing metals allows for the studying of pathomechanisms and the pathophysiology of various diseases and disorders related to the management of metals in human and animal systems.
