Trace elements have a major role as both oxidants and antioxidants, promoting and protecting from tissue damage respectively. As the liver has a pivotal role in trace elements metabolism and consequenyly their bioavailability, we aimed to measure serum levels of essential trace elements in children with chronic liver diseases (CLDs) regardless the etiology and to study their correlation with liver function tests. Serum zinc (Zn), copper (Cu) and iron (Fe); together with other trace elements parameters; were measured in 50 children with CLDs using spectrophotometry and their levels were compared with those age and sex matched healthy children as controls. Serum Cu, Fe, ferritin and transferrin saturation (TS) were significantly higher in the CLDs group than that in the control group; while serum Zn and total iron binding capacity (TIBC) were significantly lower in the CLDs than that in the control group. Serum Fe, Cu, TS and ferritin were positively correlated with biochemical parameters of liver damage; while serum Zn and TIBC were negatively correlated with biochemical parameters of liver damage. These results encourage inclusion of serum Zn, Cu and Fe as biomarkers for monitoring the severity of liver damage during routine assessment of children with CLDs. We recommended caution to avoid excess Fe and Cu intake in children with CLDs. Moreover, Zn supplementation could be encouraged in children with CLDs regardless its etiology.

“…Advanced oxidation processes such as photocatalytic oxidation, catalytic ozonation, and Fenton oxidation have gained popularity for effective organic destruction from wastewater [3], among which the Fenton reaction has attracted great attention due to its formation of highly potent chemical species, OH, for non-selective oxidation [4,5]. However, the application of homogeneous Fenton reaction is limited by the narrow working pH range (<4), separation and recovery of the iron species [6].…”

Emissions reduction or conversion by clean technologies has always been a mission for environmental protection and sustainable development. A green, electrochemically driven conversion of SO 2 to NaHSO 4 from flue gas by pH variation was conducted. Experiments were carried out to investigate some factors affecting the conversion process, such as O 2 function in flue gas, selected initial pH (pH 0 ) of solution, and CO 2 effects of high concentration. Experimental results revealed that (i) O 2 was essential for SO 2 absorption, since the pH of solution was decreased more effectively than that of flue gas without O 2 . The lowest pH of absorption solution with pouring O 2 was about 3.2, which was benefit to formatting HSO 3 -but hindering absorption of CO 2 . Meanwhile, O 2 from flue gas accelerated the adsorption of SO 2 for its oxidability to change HSO 3 -and SO 3 2-ions into SO 4 2-. (ii) At the conditions of different pH 0 , the minimum absorption efficiency of SO 2 was 89.3 %, corresponding to pH 0 5.0 and 7.0, while maximum value was 100.1 % corresponding to pH 0 6.0, which meant pH 0 6.0 was more appropriate for SO 2 conversion by electrochemistry under the experimental pH 0 range. (iii) The absorption efficiency of CO 2 was at a very low level under conditions of pH 0 5.0, 6.0, and 7.0, whose value of minimum and maximum was 0.07 and 0.19 %. The result showed that high concentration of CO 2 from flue gas had little affection on desulfurization under the experimental pH 0 range, which enable to infer that byproduct of NaHSO 4 is pure enough.
