Abstract:

Renewed focus on empirical models of sorption isotherms of hydrophobic organic contaminants (HOCs) onto mineral surfaces and soil components is required because of the importance attached to numerous pollutants released into the environment. This examines the various models and isotherms with their assumptions by different scholars on the contribution of sorption of contaminants onto clay mineral sorbents and soil organic matter with the possible ways of prevention of environmental contamination by HOCs. Literature indicated that empirical models and isotherms have been used to ascertain sever

Abstract: There are rising geologic and anthropogenic processes and as a result, now a days soils polluted by heavy metals have become more common and it is a problem across the globe. Soil polluted due to heavy metal can be freed from pollutants effectively by use of bioremediation process. It's a very well-known process and is used in situ, making it ideal to make soil free from pollutants as a part of crop establishment as well as restoration of soil which are being treated. Microorganisms as well as plants uses a variety of processes/methods to bioremediate the pollutants present in the di

Giant miscanthus (Miscanthus × giganteus Greef et Deu.) is a perennial rhizomatous grass with C4 type photosynthesis, which is distinctive by its resistance to cold temperatures when maintaining a sufficient photosynthesis rate. We revised potential of Miscanhus for use in soil bioremediation, especially from biological point of view. Translocation rate from roots to aerial part is low in general, but Miscanthus is able to grow even on highly contaminated soils without artificial fertilization. We also discussed the role of root exudates in pollutant immobilization, chelation and uptake. Comme

Soil pollution is one of the most serious environmental problems globally due to the weak self-purification ability, long degradation time, and high cost of cleaning soil pollution.

The latest research has shown that the clean-up of soil pollutants through microbial consortium is a very promising method.

Abstract:

Excessive fertilizer application in the cropping industry leads to excessive nitrogen and phosphorus in surrounding water bodies, which causes farmers to increase economic cost and damage the environment. To address the problem, we built a crop-soil runoff soil column test system, setting eight fertilizer application levels for eggplants. Then, crop yield, soil fertility and pollutant concentrations in the receiving water bodies were measured. The process of fertilizer application on the water quality of surrounding receiving water bodies and the rationality of fertilizer application were anal

Abstract:

Pollution in water bodies and soil is a major and ever-increasing environmental issue nowadays, and most conventional remediation approaches do not provide appropriate solutions. The contamination of soil is a major concern for the environment and needs to be remediated. These pollutants include complex organic compounds, heavy metals released from industries and plants and natural products such as oils from accidental release. Further the nature of pollution will be governed by the source and type of the contaminant, and other inorganic compounds are released into the environment from a numbe

Abstract:

The objective of this paper is to elaborate a system of evaluation of potential risks of transport of inorganic elements, and to create a map of soil potential to immobilisation/transportation of potential risk elements. The categorization of these risks was realized in two layers, contamination and potential soil sorption. The level of contamination was evaluated according to the Slovak Soil Law. Potential sorption of soil (PSS) is formed by qualitative (soil reaction, pH value, optical value of soil humus), and quantitative factors (C<sub, H-depth of humus horizon); it was evaluated accor

Abstract:

To study the migration and variation rule of petroleum pollutants in soil and evaluate the soil condition, the field investigation is carried out in a refinery in Yunnan Province and the relevant data are collected. Then, soil sampling and leaching experiments are carried out on the land in the refinery. Finally, the experimental data are sorted out. The experimental results show that the pollution of surface soil in refinery is the most serious. Because of the adsorb-ability of the soil, the content of petroleum pollutants in the deep soil is less. The results of leaching experiments show tha

Abstract:

As a major province of mineral resources in China, Shanxi currently has 6000 mines of various types, and acid mine drainage (AMD) is a major pollutant from the mining industry. Calcareous soil is dominant in western North China (including the Shanxi Province), therefore, clarifying the migration behavior of the main AMD pollutants (H+, S, Fe, heavy metals) in calcareous soil is essential for remediating AMD-contaminated soil in North China. In this study, the migration behavior of the main pollutants from AMD in calcareous soil was investigated using soil columns containing 20 cm of surficial

An important component of the National Forest Soils Inventory (NFSI) is the investigation of inorganic and organic pollutants. Forests are able to filter out large quantities of these substances from the atmosphere and incorporate them into the soil for a long time. The aim of this study was the integrative evaluation of organic and inorganic pollutant concentrations in forest soils in the state of Brandenburg, Germany. With the help of principle component analysis, the pollutant concentrations can essentially be explained by three significant environmental components, which explain 76% of the

This article discusses biochar adsorption and its effects on soil and discusses the future trends in this area. The large surface area, and many oxygen-containing functional groups of biochar determined by the feedstocks and the condition in pyrolysis affect the capacity of biochar to adsorb fertilizer, water, heavy metals and organic pollution. With enriched porous structures, biachar can increase the porosity and water retention capacity of soils. With the functional groups and the composition, biochar have a high adsorption capacity for fertilizer, heavy metals, organic pollutants. This pap

Bioremediation of crude oil contaminated soil is an effective process to clean petroleum pollutants from the environment. Crude oil bioremediation of soils is limited by the bacteria activity in degrading the spills hydrocarbons. Native crude oil degrading bacteria were isolated from different crude oil polluted soils. The isolated bacteria belong to the genera Pseudomonas, Mycobacterium, Arthrobacter and Bacillus. A natural biodegradable product and bacterial inoculum were used for total petroleum hydrocarbon (TPH) removal from an artificial polluted soil. For soil polluted with 5% crude oil,
