What is Simpler is More ComplexResearchers have reported that toxic element overload affects various biochemical mechanisms and physiological processes.For example, toxic elements interfere with glycolysis, Krebs cycle, uptake and absorption of minerals, metabolism of various essential elements such as iron, phosphate, calcium, zinc, and copper. They reduce cell proliferation and differentiation. In addition, they alter the normal metabolism of parathyroid hormone, male and female sex hormones, norepinephrine, cortisol, thyroid hormones, and insulin [3][4][5][6][7]. However, it is difficult to draw a causal map to

“…But, if consumed in large quantities, this can be hazardous to human health [4][5]. Natural sources of Co include water, air, soil, animals, rocks, and plants [6]. With the fast expansion in the usage of Co into the metallurgical industry for the production of alloys, rechargeable batteries, catalysts, paints, drugs, and ceramics, increasingly of it is released into the environment and entered the food chain [7][8].…”

A procedure based on dispersive liquid-liquid microextraction (DLLME) for cobalt (Co) quantification in an Iraqi environmental matrix by flame atomic absorption spectroscopy (FAAS) was applied in this work. A case-study approach was chosen to obtain further in-depth information on the Co levels and to evaluate the effectiveness of N-salicylideneaniline (SAN) as a complexing agent for pre-concentration and extraction of Co. An univariate strategy was utilized to achieve the optimum extraction conditions. The estimated limits of detection (LOD) and quantification (LOQ) under optimum conditions were 1.04 and 3.47 µg L−1, respectively. The results achieved by the proposed system were compared with those using the microwave digestion/graphite furnace atomic absorption spectrometer (MWD/GF-AAS) for digest samples and also for some water samples (Direct GF-AAS). The proposed procedure was applied for analyzing eleven environmental samples. The detectable Co levels for water samples ranged from 0.72 to 4.30 µg L−1 with a relative standard deviation of 3.7–8.8%, while the concentration for solid samples ranged from 0.17–4.51 µg g−1 (2.4–11.8 RSD %). DLLME/FAAS proposed procedure is effective, simple, and has the benefit of minimizing the organic solvent consumption by a few microliters, which results in little waste.

“…The heavy metals are hazardous to health and nonbiodegradable and undergo bioaccumulation and biomagnification through the food chain. − These metal ions cause various diseases in deficiency or at a higher concentration than the permissible limit. , For example, Fe causes anemia, hemochromatosis, and genetic mutation . Other metal ions such as Cr(VI), Hg, Co, Pb, and Cd also have adverse effects and cause major diseases affecting organs such as the liver, kidney, bone marrow, heart muscles, and neurons and genotoxicity. − Moreover, As(III) and As(V) cause cancer (arsenicosis). , In order to remove metal ions from water, several modified adsorbent materials are used, like graphene/GO, biochars, and other nanoparticles.…”

Herein, a surface-engineered violuric acid-functionalized reduced graphene oxide (rGO-VA) has been synthesized and characterized using XRD, FESEM, HRTEM-EDX, FTIR, XPS, Raman, and UV−vis spectroscopy. The surface morphology describes highly exfoliated graphene sheets and uniformly distributed VA showing a topography of average size ∼1.663 nm. The Raman and EDX spectra describe greater defects due to the presence of C, N, and O atoms on the surface of the rGO-VA. Hence, O and N-containing functional groups that are present on the surface and edge of rGO-VA facilitate the efficient adsorption of toxic metal ions. The synthesized rGO-VA efficiently removes metal ions up to 99.9% of Hg 2+ , Pb 2+ , and As 3+ , from their aqueous solutions (40 mg/L) within a short retention time (5−10 min). The removal efficiency results are unaffected even at various interferences like pH, temperature, organic pollutants, cations, and anions. The adsorption process is chemisorption, multilayer, spontaneous, endothermic, and random. During the adsorption process, the residual concentrations were initially analyzed using UV−vis spectroscopy, and the results were verified by AAS. Overall, the present surface-engineered rGO-VA may be crucial for developing an efficient adsorbent to remove toxic metal ions from wastewater.
