“…The results obtained in this study confirm previous studies that HMs may pose ecological and human health risk [ 110 , 111 , 112 ]. The main exposure pathways from surface water to humans are water ingestion, water used to agricultural irrigation and direct contact with water during recreation activities [ 113 ]. According to Hoang et al [ 113 ], HMs adverse effects on human health include cancer, anemia and diabetes.…”

This study investigated the spatial distribution, contamination, potential ecological risks and quantities of pollutant sources of six heavy metals (HMs) in sediments of 47 rivers. The catchments of the investigated rivers are situated in Poland, but some of them are located in Slovakia, the Czech Republic, and Germany. Cluster analysis was applied to analyze the spatial distribution of Cd, Cr, Cu, Ni, Pb, and Zn in river sediments. Moran I and Getis-Ord Gi* statistics were calculated to reveal the distribution pattern and hotspot values. Principal component analysis (PCA) and positive matrix factorization (PMF) were used to identify pollution sources. Furthermore, geochemical indices and sediment quality guidelines allowed us to assess sediment contamination and potential toxic effects on aquatic biota. The results showed that in 1/3rd of the rivers, the HM pattern and concentrations indicate sediment contamination. The EF, PLI, and MPI indices indicate that concentrations were at a rather low level in 2/3rd of the analyzed rivers. Only in individual rivers may the HMs have toxic effects on aquatic biota. Spatial autocorrelation analysis using the Moran I statistic revealed a random and dispersed pattern of HMs in river sediments. PCA analysis identified two sources of HMs’ delivery to the aquatic environment. Cr, Cu, Ni, Pb, and Zn originate from point and non-point sources, while Cd concentrations have a dominant natural origin. The PMF identified three sources of pollution. Among them, urban pollution sources are responsible for Cu delivery, agricultural pollution for Zn, and industrial pollution for Ni and Cr. Moreover, the analysis showed no relationship between catchment land-use patterns and HM content in river sediments.

Background: Today, soil pollution with heavy metals and petroleum compounds is one of the main environmental problems. This research was done to investigate the effect of drought stress, soil salinity, Piriformospora indica (P. indica), and MWCNs on biodegradation of diesel oil in the soil that contaminated with Pb and Cd under cultivation of triticale plant. Methods: Treatments consisted of applying MWCNs (2% [W/W]) in the Pb- and Cd-polluted soil that was simultaneously polluted with diesel oil (0, 5, and 10% [W/W]), and the plants used in this study were inoculated with P. indica. After 70 days, plants were harvested, and plant and soil Cd were measured using AAS (atomic absorption spectrometry). In addition, the degradation percentage of diesel oil in soil was determined. Results: Soil application of MWCNs at the rate of 2% (W/W) significantly increased the biodegradation of diesel oil in the soil in the drought and salinity (6 dS/m) stress by 11.3% and 15.6%, respectively. In addition, plant inoculation with P. indica significantly increased the biodegradation of diesel oil in the soil by 12.3%. For salinity (6 dS/m) and drought stress, it was increased by 8.3% and 9.4%, respectively. In addition, the Pb and Cd concentrations decreased by 14.3% and 12.8%, respectively, when the MWCNs were added to the soil (2% [W/W]). Conclusion: Soil application of MWCNs and plant inoculation with P. indica not only increased the biodegradation of diesel oil but also decreased the plant Pb and Cd concentrations.

“…Water contaminants can be organics, microbes, dyes, metal particles; lead, cadmium, zinc, nickel, arsenic, chromium and mercury with non-biodegradable nature representing an extraordinary hazard to human wellbeing. Substantial metal particles can cause numerous unfavorable influences like a malignant growth, kidney damage, hepatitis, unsuccessful labor, iron deficiency, encephalopathy and nephritic disorder, and so forth [ 1 , 2 , 6 , 7 , 10 , 11 , 14 ]. Nickel particles can cause skin diseases when reached with gems destroying zips, watches, coins and so on.…”

Nanomaterials for the Treatment of Heavy Metal Contaminated Water

Nanotechnology finds its application almost in every field of science and technology. At the same time, it also helps to find the solution to various environment-related problems, especially water contamination. Nanomaterials have many advantages over conventional materials, such as high surface area, both polar and non-polar chemistries, controlled and size-tunable, easier biodegradation, which made them ideal candidates for water and environmental remediation as well. Herein, applications of non-carbon nanomaterials, such as layered double hydroxides, iron oxide magnetite nanoparticles, nano-polymer composites, metal oxide nanomaterials and nanomembranes/fibers in heavy metal contaminated water and environmental remediation are reviewed. These non-carbon nanomaterials, due to their tunable unique chemistry and small size have greater potentials for water and environmental remediation applications.
