Differential Growth and Metal Accumulation Response of Brachiaria Mutica and Leptochloa Fusca on Cadmium and Lead Contaminated Soil Soil Sediment Contam. (IF 1.25) Pub Date : 2020-06-19 Sana Ullah; Rehmat Ali; Sajid Mahmood; Muhammad Atif Riaz; Kalsoom Akhtar
ABSTRACT This work aims to assess growth, physiology, and metal uptake response of Brachiaria mutica and Leptochloa fusca under different contamination levels of Cd (10 and 50 mg kg−1) and Pb (50 and 250 mg kg−1) stress. Results of pot trial showed increasing metal concentration affected B. mutica more as compared to L. fusca. In B. mutica metal stress substantially reduced shoot dry biomass, root

Iron Enriched Green Manure Can Increase Wheat Fe Concentration in Pb-polluted Soil in the Presence of Piriformospora Indica (P.indica) Soil Sediment Contam. (IF 1.25) Pub Date : 2020-05-30 Amir Hossein Baghaie; Aminollah Aghilizefreei
Soil pollution with heavy metals and iron (Fe) malnutrition is big concern of industrial areas in arid and semi-arid regions. We studied the potential of Fe-enriched green manures application and Piriformospora indica (P.indica) to increase grain Fe concentration of two bread wheat genotypes differing in Fe efficiency (Triticum aestivum L. cvs. Falat, and Durum) in a Pb-polluted soil. To prepare Fe-enriched

Metals/metalloid in Marine Sediments, Bioaccumulating in Macroalgae and a Mussel Soil Sediment Contam. (IF 1.25) Pub Date : 2020-04-24 Nigar Alkan; Ali Alkan; Ahmet Demirak; Moez Bahloul
The aim of the present work is to broaden our knowledge on the variability of metals and metalloid concentration levels in surface sediments, macroalgae and mollusc. Accordingly, As, Co, Cr, Cu, Mn, Mo, Ni, Pb, and Zn levels in surface sediments, marine macroalgae species (Ulva intestinalis and Ceramium rubrum) and mollusk (mussel Mytilus galloprovincialis) collected from nine stations along the Sürmene

Behavioral Analysis of Folsomia Candida (Collembola) with Herbicide Using Electronic and Computational Instrumentation: Bioassays Soil Sediment Contam. (IF 1.25) Pub Date : 2020-04-20 Rodrigo Luiz Ximenes; Adelle Anik Araújo Gomes; Talía Simões Dos Santos Ximenes; Marta Siviero Guilherme Pires
In view of the constant biological researches, it is important to highlight the necessity to develop new instrumentation techniques. In this way, it is possible to use organisms as biological sensors to define new methodologies for a better understanding of the behavior of living beings. Indiscriminate contamination of soil by herbicide has been receiving more attention due to the increase in agriculture

Human Health Risk Assessment and Early Warning of Heavy Metal Pollution in Soil of a Coal Chemical Plant in Northwest China Soil Sediment Contam. (IF 1.25) Pub Date : 2020-04-11 Kai Zhang; Xinhui Zheng; Huifang Li; Zhehui Zhao
In this paper, 153 samples of heavy metals in the soil of a coal chemical plant in Northwest China were collected in the study area to predict and evaluate the human health risks of arsenic (As), cadmium (Cd), chromium (Cr(VI)), lead (Pb), and mercury (Hg) in the soil of the plant area in 2021, 2026, and 2031 and their change laws by referring to the “Soil Environmental Capacity Model,” “Technical

Anionic contamination and its stabilization on the strength and plastic features of clay soils (vermiculite and sepiolite) Soil Sediment Contam. (IF 1.25) Pub Date : 2020-04-09 Hanie Abbaslou; Parvaneh Poorangha; Somayeh Bakhtiari; Ali Reza Ghanizadeh
Utilizing fine-grained soils containing clay minerals in most of the structures due to the specific surface area, ion exchange capacity and high adsorption capacity of hazardous contaminants have always been considered with the geotechnical view of the environment. In this study, the effect of contamination and stabilization of anionic pollutants (As) on the most important mechanical and physical properties

Mitigating Cadmium Accumulation in Spinach and Onions by the Application of Silicon Fertilizer to Soil Soil Sediment Contam. (IF 1.25) Pub Date : 2020-04-09 Colin William Gray; Bridget Elizabeth Wise
Cadmium (Cd) is readily absorbed by plants and can accumulate to concentrations that exceed food standards. Testing strategies that can mitigate plant uptake of Cd are essential to help manage the risk to food quality. We measured whether applying silicon (Si) fertilizer to a soil contaminated with Cd from phosphate fertilizer could decrease Cd concentrations in spinach (Spinacia olearacea) and onion

Toleration and Accumulation of Cotton to Heavy Metal - Potential Use for Phytoremediation Soil Sediment Contam. (IF 1.25) Pub Date : 2020-04-09 Changfeng Li; Cangsong Zheng; Kehai Zhou; Wenbing Han; Changjiu Tian; Sihong Ye; Changbao Zhao; Hao Zhou; Xiaoming Yan; Xiongfeng Ma
Heavy metal contamination of agricultural soil has become a critical issue worldwide. A sustainable approach to mitigate heavy metal contamination is extremely important. Phytoremediation has been proved to be a well alternative for soil remediation as cost-effective, environment friendly, and esthetically pleasing. This review briefly elucidates heavy metal tolerance, uptake, and the corresponding

Dynamic Risk Assessment of Lead Pollution of Shooting Range Soil by Applying the Delayed Geochemical Hazard Model – A Case Study in Botswana Soil Sediment Contam. (IF 1.25) Pub Date : 2020-04-07 Pogisego Dinake; Rosemary Kelebemang; Nicholas Sehube; Tsotlhe Trinity Kereeditse; Obakeng Motswetla
The delayed geochemical hazard (DGH) model was used to show that environmental pollution risk from Pb is a dynamic process as opposed to static. The DGH model describes the potential transformation and release of Pb partitioned in the different fractions of the soil that may be inert but becoming reactive when the conditions of the soil such as pH, moisture, and organic matter become favorable or when
