Mathematical Models of Inverse Problems for Finding the Main Characteristics of Air Pollution Sources Water Air Soil Pollut. (IF 1.9) Pub Date : 2020-11-24 Artur O. Zaporozhets, Vladyslav V. Khaidurov
The paper describes optimization of mathematical models for determining the main characteristics of the source of environmental pollution. A modification of the classical Newton’s method for finding a numerical solution of the constructed mathematical models for identifying the parameters of an environmental pollutant has been developed. A modification of the classical Newton’s method is obtained,

Use of Eggshell as a Low-Cost Biomaterial for Coal Mine-Impacted Water (MIW) Remediation: Characterization and Statistical Determination of the Treatment Conditions Water Air Soil Pollut. (IF 1.9) Pub Date : 2020-11-21 Thamires Custódio Jeremias, Tatiana Pineda-Vásquez, Flávio Rubens Lapolli, María Ángeles Lobo-Recio
Eggshells (ESs), a low-cost biosorbent rich in calcium carbonate (CaCO3), were used to sustainably reduce the acidity and remove the Fe(total), Al3+, and Mn(total) ions from coal mine-impacted water (MIW). The surface area and pore volume of ES biomaterial were 5.692 m2 g−1 and 0.0567 cm3 g−1, respectively. The remediation process was performed in two consecutive stages, with Fe(total) and Al3+ ions

Temporal Variation of Road Dust Load and Its Size Distribution—a Comparative Study of a Porous and a Dense Pavement Water Air Soil Pollut. (IF 1.9) Pub Date : 2020-11-17 Joacim Lundberg, Mats Gustafsson, Sara Janhäll, Olle Eriksson, Göran Blomqvist, Sigurdur Erlingsson
Resuspension of road dust contributes to air quality issues with resulting health impacts. Limited studies imply that porous pavements can initially mitigate PM10 emissions by acting as a dust trap, but the abrasion wear generates road dust and thus accelerates the clogging processes. In addition, knowledge regarding the impact of pavement types on road dust load dynamics is limited. Road traffic noise

Discovering Decolorization Potential of Triphenylmethane Dyes by Actinobacteria from Soil Water Air Soil Pollut. (IF 1.9) Pub Date : 2020-11-17 Nurul Hidayah Adenan, Yau Yan Lim, Adeline Su Yien Ting
This study investigates the decolorization potential of actinobacteria from soil towards toxic triphenylmethane (TPM) dyes, i.e., malachite green (MG), methyl violet (MV), crystal violet (CV), and cotton blue (CB). The actinobacterial isolates were first isolated from fresh soil samples, plated onto actinomycetes isolation agar (AIA), and both live and dead cells were prepared to evaluate their decolorization

Removal and Recovery of Phosphorus from Contaminated Water Using Novel, Reusable, Renewable Resource-Based Aluminum/Cerium Oxide Nanocomposite Water Air Soil Pollut. (IF 1.9) Pub Date : 2020-11-17 Amita Nakarmi, Rebecca Moreira, Shawn E. Bourdo, Fumiya Watanabe, Alan Toland, Tito Viswanathan
The combination of cerium oxide and aluminum oxide nanocomposites in quaternary ammonium–modified wood has been shown to be excellent for phosphorus (as phosphate) removal from contaminated waters. The results are better than using single metal oxides in the nanocomposite based on the adsorption capacity and kinetic rate. The mixed metal oxide nanocomposite on pine wood chips (a renewable resource)

Investigation of Shiga Toxin-Producing Escherichia coli in Groundwater, River Water, and Fecal Sources in the Kathmandu Valley, Nepal Water Air Soil Pollut. (IF 1.9) Pub Date : 2020-11-16 Niva Sthapit, Bikash Malla, Rajani Ghaju Shrestha, Sarmila Tandukar, Jeevan B. Sherchand, Eiji Haramoto, Futaba Kazama
Shiga toxin-producing Escherichia coli (STEC) is one of the most commonly heard sources of foodborne outbreaks but presently lacks studies of in the Kathmandu Valley. This study explored the presence of STEC in river water (n = 17), groundwater (n = 83), feces (n = 50), and manure (n = 20) in the Kathmandu Valley, Nepal. Samples that were confirmed to be E. coli–positive using the Colilert assay in

Dissipation Behavior and Residue Distribution of Famoxadone and Cymoxanil in Cucumber and Soil Ecosystem Under Open-Field Conditions Water Air Soil Pollut. (IF 1.9) Pub Date : 2020-11-16 Jifa Rao, Ling Chen, Yujia Xiang, Jiayu Li, Xiao Chen, Yaoyu Zhou
In this study, a practical and excellent method was used to determine the famoxadone and cymoxanil via high-performance liquid chromatography equipped utilizing ultraviolet detector lamp (HPLC-UV) for investigating the dissipation behavior and residue distribution of famoxadone and cymoxanil in cucumber and soil ecosystem. The limit of quantification (LOQS) of famoxadone and cymoxanil in cucumber were

Comparison of Organic Materials for the Passive Treatment of Synthetic Neutral Mine Drainage Contaminated by Nickel: Adsorption and Desorption Kinetics and Isotherms Water Air Soil Pollut. (IF 1.9) Pub Date : 2020-11-16 Dominique Richard, Alfonso Mucci, Carmen M. Neculita, Gérald J. Zagury
Sorption is an effective process for the remediation of mine water with low metal concentrations. To identify promising low-cost organic sorbents for nickel (Ni), adsorption and retention properties of peat, compost, brown algae, sawdust, and wood ash were compared. Batch adsorption and desorption experiments were conducted at pH 7 in 0.05 M NaNO3 solutions to simulate the ionic strength and pH of
