“…The World Health Organization consider that concentrations of Fe ions as low as 35 μM in water can start to have unwanted effects for human health [ 5 ], inducing a variety of disorders including Parkinson’s and Alzheimer’s diseases, low blood pressure and many more [ 6 ]. There are plenty of methods for detecting unwanted concentrations of heavy metal ions, including Fe ions, for example chromatography [ 7 ], atomic absorption spectroscopy [ 8 ], electrochemical methods [ 9 ], surface enhanced Raman spectroscopy [ 10 ], inductively coupled plasma mass spectroscopy [ 11 ], etc. Yet, all of these sensing techniques share the same drawbacks related to their time- and money-consuming character, considering that the samples need to be moved to dedicated laboratories and institutions, where only trained personal using expensive equipment can perform the specific detection of the desired ions.…”

Herein is presented a novel and efficient portable paper-based sensing platform using paper-incorporated histidine stabilized gold nanoclusters (His-AuNCs), for the sensitive and selective detection of Fe ions from low-volume real water samples based on photoluminescence (PL) quenching. Highly photoluminescent colloidal His-AuNCs are obtained via a novel microwave-assisted method. The His-AuNCs-based sensor reveals a limit of detection (LOD) as low as 0.2 μM and a good selectivity towards Fe ions, in solution. Further, the fabricated portable sensing device based on paper impregnated with His-AuNCs proves to be suitable for the easy detection of hazardous Fe levels from real water samples, under UV light exposure, through evaluating the level of PL quenching on paper. Photographic images are thereafter captured with a smartphone camera and the average blue intensity ratio (I/I0) of the His-AuNCs-paper spots is plotted against [Fe2+] revealing a LOD of 3.2 μM. Moreover, selectivity and competitivity assays performed on paper-based sensor prove that the proposed platform presents high selectivity and accuracy for the detection of Fe ions from water samples. To validate the platform, sensing assays are performed on real water samples from local sources, spiked with 35 μM Fe ions (i.e., Fe2+). The obtained recoveries prove the high sensitivity and accuracy of the proposed His-AuNCs-paper-based sensor pointing towards its applicability as an easy-to-use, fast, quantitative and qualitative sensor suitable for on-site detection of toxic levels of Fe ions in low-volume real water samples.

“…This is because high concentrations of Cu and Zn in water can cause a lot of harm to human health if water is consumed frequently. Exposure to high Cu levels is associated with increased cardiovascular morbidity, liver damage, and neurological disorders (Prakash et al, 2015), while excessive Zn levels may cause impaired lymphocyte function (Haase and Rink, 2014;Salnikova et al, 2018). The increase of Cu and Zn in the solution may also potentiate toxicity to several plant species exposed to these conditions (Tiecher et al, 2016;De Conti et al, 2016;Girotto et al, 2016;Miotto et al, 2017;Brunetto et al, 2017).…”

Establishing Cu and Zn transport limits to soil solution, may be a parameter to regulate maximum allowable concentrations of these heavy metals in soils. The study aimed to estimate Cu and Zn contents in soil mixtures with varying clay and soil organic matter (SOM) contents, from which the two heavy metals are transported to the soil solution. Samples of the Bw horizon of a Oxisol and of the A horizon of a Inceptisol were used to make soil mixtures with clay contents ranging from 170 to 700 g kg− 1 and SOM ranging from 18 to 95 g kg− 1. Cu and Zn adsorption curves were obtained to determine the maximum adsorption capacities (MAC) using the Langmuir model. Cu transport limits ranged from 118 to 187 mg kg− 1 the lowest values were found in soil mixtures containing lower clay contents in combination with higher SOM contents. Zn transport limits ranged from 61 to 116 mg kg− 1 the highest values were found in soil mixtures containing lower clay contents combined with higher SOM contents. Cu and Zn transport limits can be used as safe limits for supervisory bodies, technical assistance institutions and farmers to monitor the potential for environmental contamination.

A large amount of copper (Cu) used in production activities can lead to the enrichment of Cu in the environment, which can cause toxicity to animals. However, the toxicity mechanism of Cu on the cerebrum is still uncertain. Hence, a total of 240 chickens were separated into four groups in this study to reveal the potential connection between mitophagy and endoplasmic reticulum (ER) stress-mediated apoptosis in the chicken cerebrum in the case of excess Cu exposure. The cu exposure situation was simulated by diets containing various levels of copper (11 mg/kg, control group; 110 mg/kg, group I; 220 mg/kg, group II and 330 mg/kg, group III) for 49 days. The results of histology showed that vacuolar degeneration was observed in the treated groups, and the mitochondria swell and autophagosomes formation were found under excess Cu treatment. Additionally, the expression of mitophagy (PINK1, Parkin, LC3I, LC3II and p62) and ER stress (GRP78, PERK, ATF6, IRE1α, XBP1, CHOP, and JNK) indexes were significantly upregulated under excess Cu exposure. Furthermore, the mRNA and protein expression of Bcl-2 were decreased, while Bak1, Bax, Caspase12, and Caspase3 were increased compared to the control group. In summary, this study demonstrated that an overdose of Cu could induce mitophagy and ER stress-mediated apoptosis in the chicken cerebrum. These findings revealed an important potential connection between Cu toxicity and cerebrum damage, which provided a new insight into Cu neurotoxicity.
