Soil Use and Management, Accepted Article. Heavy metals and metalloids can accumulate in soil, with potentially toxic effects to human health and ecosystems, threatening the sustainable use and management of soil resources. Although a number of remediation technologies, such as Solidification/Stabilization (S/S), soil washing, electrokinetic remediation and chemical oxidation/reduction can be...

Heavy metals in ecosystems affect human health through the web chain. Castellon province is home to the largest ceramic production hub in Spain, with 94 % of the country's total production Agricultural soils in the vicinity of the ceramic hub were reported to contain potentially toxic elements (Pb, Cr, Ni and Cd) in 2008 and have since been subject to repeated amendment with biosolids (sewage...

The Contamination agricultural soils and food by cadmium(cd) is one of the major concerns of the world. The field experiments were conducted to investigate the effects of silicon (Si) fertilizer on bioavailability and accumulation of Cd in soil, Cd chemical fractions, dynamic changes of soil pH, available Cd content and Cd content of various parts of rice plants. The results revealed that...

Biochar has various ecological effects on heavy‐metal‐contaminated soils. Biochar can passivate the activity of heavy metals and improve environmental conditions for microbial growth. A greenhouse pot experiment was conducted to explore the diversity of microbes in red soil under cadmium (Cd) stress following the application of wheat straw biochar. The contaminant Cd was prepared at 2.5 mg kg‐1...

Tropical peatlands are unique and globally important ecosystems for carbon storage, that are generally considered nutrient poor. However, different nutrient and heavy metal concentrations in these complex ecosystems and their interactions with carbon emissions are largely unknown. The objective of this research was to explore the concentrations of macro‐ and micro‐nutrients and other heavy metals...

This study focused on the physical, chemical and microbiological characteristics of soils from different grasslands in the Budapest area. Our aim was to assess the influence of anthropogenic activities on these soils by comparing three types of site: urban, green‐urban, and non‐urban. From these sites, a total of 72 topsoil samples were collected and analyzed. The results indicated that many...

Accidental flowback water spills can cause serious soil pollution. Nickel (Ni) is one of the common heavy metal components in the flowback water. However, the behavior and mechanism of Ni in flowback water in dolomite‐derived laterite soil is poorly understood. In this study, laterite soils were selected from a Cambrian dolomite strata in China.Column experiments and synthetic flowback water were...

The unsustainable use of phosphate‐based fertilizers can lead to the depletion of accessible phosphorous reserves and cause environmental problems. As well as finding new phosphate supplies, we ought to be prioritizing sustainable phosphate‐based fertilizers. By adopting microbial, physical and chemical modifications, low‐solubility phosphate minerals could be used in an efficient way for...

This study focused on the effects of biochar (BC) application on soil chemical properties and mobilization of cadmium (Cd) and lead (Pb) in the paddy soil. BC was applied at the rate of 0, 10, 20 and 40 t ha‐1, respectively. BC application caused significant increase in soil organic carbon contents (SOC), pH, nitrate nitrogen (NO3‐‐N), and available phosphorus contents (AP) in the top and...

The likelihood of co‐selection for antibiotic resistance induced by heavy metals is a potential threat to human health, however direct evidence of heavy metal induced co‐selection of antibiotic resistance is lacking in soil. By using a metagenomic sequencing approach, zinc (Zn) driven co‐selection of antibiotic resistance genes (ARGs) in soil was investigated through a microcosm experiment where...
