Infectious diseases caused by soil-transmitted helminths (STHs) are important diseases of humans, which affect about one third of the world’s population. Examination of soil can be used to estimate the risk of STH infection in humans. We carried out this survey to clarify the current status of soil contamination by parasite eggs and to assess the risk of STH infection. During survey periods, we...

This study aims to evaluate soil climate quantitatively under present and projected climatic conditions across Central Europe (12.1°–18.9° E and 46.8°–51.1° N) and the U.S. Central Plains (90°–104° W and 37°–49° N), with a special focus on soil temperature, hydric regime, drought risk and potential productivity (assessed as a period suitable for crop growth). The analysis was completed for the ...

The data on the heavy metal content at different soil depths derived from a multi-purpose regional geochemical survey in the Pearl River Delta (PRD) were analyzed using ArcGIS 10.0. By comparing their spatial distributions and areas, the sources of heavy metals (Cd, Hg, As and Pb) were quantitatively identified and explored. Netted measuring points at 25 ×25 km were set over the entire PRD acco...

Heathlands are threatened habitats throughout the whole Europe, which have initiated numerous restoration programmes aimed mostly at plant community reconstruction; however, little is known about soil fauna restoration. Here we studied newly established wet and dry heathlands in Netherlands after topsoil removal of previously agricultural land, where manipulated pH (acidification by Sulphur or ...

Background: The present study investigated the impact of land use on health risks (cancerous and non-cancerous) of heavy metals in soil along the Hemmat Highway of Tehran, Iran. Materials and Methods: A total of 28 soil samples were collected in August 2014 from the roadside soil of the Hemmat Highway. The collected samples were air-dried and digested, and then, analyzed for heavy metals usi...

The environmental quality of soil in the central part of the Northern Plateau of Spain has been analyzed by studying the heavy metal content of 166 samples belonging to the horizons A, B and C of 89 soil profiles. The analysis to assess the environmental risk of heavy metals in the soil was carried out by means of the spatial distribution of nine heavy metals and the use of several pollution in...

BACKGROUND The coexistence of Cd2+ and Zn2+ ions in nature has a significant influence on their environmental behaviors in soils and bioavailability for plants. While many studies have been done on the mutual toxicity of Cd2+ and Zn2+, few studies can be found in the literature focused on the interaction of Cd2+ and Zn2+ on soil clay fractions especially in terms of energy relationship. RESUL...

The potential health risk from exposure to chemically contaminated soil can be assessed from bioavailability studies. The aims of this research were: (a) to determine the dermal bioavailability of contaminants in soil for representatives of the polycyclic aromatic hydrocarbon class of chemicals, namely, benzo(a)pyrene and naphthalene, and (b) to examine the relative contribution of soil matrix ...

The objective of the paper is to propose a risk assessment model for agricultural engineering related to biosafety and security while deploying agriculture information through the latest computing and communication technologies for farmers. The earlier works concentrate much on the biological risk and agricultural risk without focusing on the effects of uncertainty in different computing and co...
