Special Issue Information

Dear Colleagues,

Environmental pollution has adversely affected the natural ecosystem, and subsequently human health, because of the presence of hazardous materials such as organic pollutants and heavy metals. Furthermore, another issue is the accumulation of non-degradable hazardous materials in our environment. Therefore, there is a need to remove these materials from the environment, such as from soil and water.

Overall, “remediation” means solving environmental problems using a wide range of methods. Remediation technologies are too numerous and can generally be categorized into ex situ and in situ methods. Various mechanisms have been developed for the remediation or partial removal of these hazardous compounds, which are described as bioremediation (using biological organisms to remove contaminated soil or water, such as bioaugmentation, with the addition of bacterial cultures to speed up the rate of degradation of a contaminant), phytoremediation (use of free-floating, submerged, or emergent plants to uptake contaminants in their tissues), and biosorbent materials, which either originated from natural sources such as waste shell or are commercially based such as activated carbon.      

This Special Issue welcomes papers that examine recent experimental, computational, and theoretical research of contaminant remediation technologies using natural, constructed, or modified systems. We aim to publish a comprehensive collection of papers that describe the fate and transport of different types of contaminants after remediation, using empirical or statistical models. Submissions that include the remediation of contaminants using various methods are encouraged. The main topics for the Special Issue are presented below:

  • Source and fate of contaminants in soil and water;
  • Innovative remediation technologies for soil and water remediation;
  • Remediation of contaminated sites with heavy metal and other contaminants such as polyaromatic hydrocarbons;
  • Microplastic and persistent organic pollutant fate and remediation;
  • Site-, field-, and lab-scale remediation experiments;
  • Public health aspects of contamination existence in the environment;
  • Health policy related to the persistency of specific contaminants in the environment and their remediation.

In Chile, there are several abandoned mine tailing impoundments near population centers that need to be remediated. In this study, the ability of Oxalis gigantea, Cistanthe grandiflora, and Puya berteroniana to remove Zn, Ni, and Cr from mine tailings was evaluated. The plants’ removal efficiency, bioconcentration, and translocation factors regarding these metals were determined to assess the ability of certain endemic species from Northern and Central Chile to extract or stabilize metals. After a period of seven months, the chemical analysis of plants and tailings, together with the statistical treatment of data, indicated the inability of all the species to translocate Ni, Cr, or Zn with a translocation factor lower than one. The results showed the stabilizing character of Oxalis gigantea, Puya berteroniana, and Cistanthe grandiflora for Zn, with a bioconcentration factor close to 1.2 in all cases, and the same ability of the latter two species for Cr, with a bioconcentration factor of 1.5 in the case of Cistanthe grandiflora and 1.7 for Puya berteroniana. Finally, a removal efficiency of 9.3% was obtained with Cistanthe grandiflora for Cr and 15% for Ni; values lower than 6.4% were obtained for Zn in all cases. Improvements in the process should be sought to enhance the performance of these species for the accumulation of the target metals. Full article

In this study, marine sediment (MS) was successfully used as a source of methanogenic bacteria for the anaerobic digestion (AD) of chicken manure (CM). Using MS showed high production in liquid and semi-solid conditions. Even in solid conditions, 169.3 mL/g volatile solids of chicken manure (VS-CM) was produced, despite the accumulation of ammonia (4.2 g NH3-N/kg CM). To the best of our knowledge, this is the highest methane production from CM alone, without pretreatment, in solid conditions (20%). Comparing MS to Ozouh sludge (excess activated sewage sludge) (OS), using OS under semi-solid conditions resulted in higher methane production, while using MS resulted in more ammonia tolerance (301 mL/gVS-CM at 8.58 g NH3-N/kg). Production optimization was carried out via a response surface methodology (RDM) model involving four independent variables (inoculum ratio, total solid content, NaCl concentration, and incubation time). Optimized methane production (324.36 mL/gVS-CM) was at a CM:MS ratio of 1:2.5 with no NaCl supplementation, 10% total solid content, and an incubation time of 45 days. Full article
