Special Issue Information

Dear Colleagues,

In this era of industrialization, environmental pollution is a major global issue.  Nowadays, a high number of environmental problems affect climate, ecosystems, biodiversity, and human health worldwide due to the contamination of the air, soil, and water.  One of the most important issues is related to heavy metal (HM) pollution. HMs normally occur in nature and become toxic through accumulation in organisms. Nowdays, these types of pollutants may be discarded in waters, soils, and the atmosphere due to expanded agricultural industry, improper waste disposal, metal industries, and the use of fertilizers and pesticides. The most common HMs in the environment are Hg, Pb, Cr, As, and Cd; among these, Hg is of the greatest concern due to its biomagnification and ability to form organic compounds and travel long distances in the atmosphere.

As a consequence, scientific research is continuously in search of materials, nanomaterials, nanoparticles, or advanced materials for use as increasingly efficient sensing materials for the fast detection of HMs, adsorption, and depuration from HMs for the benefit of the environment.

For these reasons, you are invited to submit a manuscript to this Special Issue that aims to collect contributions on new materials and green strategies with a reduced impact on the environment, with a view to preserving the ecosystem and promoting sustainable development. These materials, designed from the perspective of encouraging innovation, can be obtained with alternative green methods and new synthetic or biosynthetic methods, and also using waste products to obtain high yields in production and a beneficial environmental impact.

The expansion of urban construction areas can reduce the infiltration rate of rainwater in permeable land, and a large amount of runoff rainwater cannot penetrate the soil. In extreme rainstorm weather, it is easy to cause serious urban waterlogging problems. To improve the infiltration and decontamination ability of green space soil, two types of inorganic ameliorants (i.e., sand and grain shell) and structural ameliorants (i.e., desulfurization gypsum and polyacrylamide) were utilized as amendments in the soil. The influence of the selected ameliorants on the infiltration and decontamination ability was analyzed through a soil infiltration test, soil pore distribution determination and a soil decontamination test. Three parameters including the soil infiltration rate, pore distribution characteristics and pollutant removal rate were proposed. The results showed that sand, grain shells and desulfurization gypsum (FGD gypsum) all enhanced the infiltration capacity of soil, while PAM decreased the infiltration capacity. Meanwhile, mixed sand and grain shell with the FGD gypsum and polyacrylamide can effectively improve the decontamination capacity of the soil. Comprehensive analysis showed that the better improvement combination is 10% sand + 20% grain hull + 0.5 g/kg FGD gypsum + 0.1 g/kg PAM. Full article

Cr is used extensively in industry, so the number of Cr (VI) hazards is increasing. The effective control and removal of Cr (VI) from the environment are becoming an increasing research priority. In order to provide a more comprehensive description of the research progress of chromate adsorption materials, this paper summarizes the articles describing chromate adsorption in the past five years. It summarizes the adsorption principles, adsorbent types, and adsorption effects to provide methods and ideas to solve the chromate pollution problem further. After research, it is found that many adsorbents reduce adsorption when there is too much charge in the water. Besides, to ensure adsorption efficiency, there are problems with the formability of some materials, which impact recycling. Full article
