Under rapid urban sprawl in Northeast China, land conversions are not only encroaching on the quantity of cultivated lands, but also posing a great threat to black soil conservation and food security. This study's aim is to explore the spatial relationship between comprehensive cultivated soil heavy metal pollution and peri-urban land use patterns in the black soil region. We applied spatial la...

Fungi and fungal community play important roles in the soil ecosystem, and the diversity of fungal community could act as natural antagonists of various plant pathogens. Biological control is a promising method to protect plants as chemical pesticides may cause environment pollution. Pseudomonas fluorescens 2P24 had strong inhibitory on Rastonia solanacearum, Fusarium oxysporum and Rhizoctonia ...

Background: Soil serves as a major reservoir for contaminants as it can bind to various chemicals. The aim of this study was to evaluate the levels of some metals (Cd, Cu, Fe and V) in soil samples collected from different stations of Ahvaz Industrial Complex II to determine the natural and anthropogenic contribution of metal in the soil. Methods: This was an experimental study that carried ou...

The important role of earthworms in the biomagnification of heavy metals in terrestrial ecosystems is widely recognised. Differences in earthworm biomass between sites is mostly not accounted for in ecological risk assessment. These differences may be large depending on soil properties and pollution status. A survey of earthworm biomass and colonisation rate was carried out on dredged sediment-...

Recently, kernel-based Machine Learning methods have gained great popularity in many data analysis and data mining fields: pattern recognition, biocomputing, speech and vision, engineering, remote sensing etc. The paper describes the use of kernel methods to approach the processing of datasets from environmental monitoring networks. Several typical problems of the environmental sciences and the...

Private vegetable gardens are often contaminated with elevated levels of heavy metals (HM). Bioindication, using the visible symptoms developing in leaves, can provide simple, cost-effective and reliable detection of soil pollution. In this experiment five species of vegetables from different families were exposed to soil contaminated with HM dust given as copper / zinc / cadmium/ lead = 640 /3...

the purpose of this article is to present the development of a wind farm, with a condition monitoring system (cms) based on control charts as the algorithm, centred on a new index, to prevent soil pollution by oil spills in wind farms. to this end, temperature sensors can be considered as one of the more significant sensors to be employed in this study, because the information obtained with reg...

The spatial distribution characteristics of six heavy metals and metalloid in soil of Zhuji Lipu copper mining area, Zhejiang Province, was studied by using geostatistics approaches combined with GIS. These elements included Pb, As, Cr, Cu, Zn and Ni. The statistical analyses showed that concentrations of these elements were lognormal distribution. Concentrations of Pb, As, Cu, Zn and Ni were s...

A phytoextraction treatment enhanced by electric field to decontaminate a heavily Pb polluted soil has been tested in a greenhouse-scale experiment. Brassica juncea was selected as Pb-hyperaccumulator plant. The influence of the application of two Electric Potential Difference values (0.6 and 1.1 V cm) and the addition of EDTA (2.5 mmol kg) on biomass production, plant uptake, contaminant leach...
