Soil dwelling organisms, plants and many primary consumers in food webs face the challenge of exposure to contaminants emerging concern (CECs) present terrestrial systems, including thousands substances derived from pharmaceutical personal care products (PPCPs). The recent increase consumption modern human or veterinary drugs has resulted a surge anthropogenic pharmaceuticals, frequently introd...

Soil organic carbon (SOC) sequestration with enhanced stable carbon storage has been widely accepted as a very important ecosystem property. Yet, the link between carbon stability and bio-activity for ecosystem functioning with OC accumulation in field soils has not been characterized. We assessed the changes in microbial activity versus carbon stability along a paddy soil chronosequence shifti...

The Agh-Dareh and Zarshouran mines are two known active gold deposits in Takab, NW Iran. In the present study, the potentials of two species of Astragalus (A. microcephalus from Agh-Dareh and A. effusus from Zarshouran mines), as the dominant plants grown in these areas, were assessed for the bio-accumulation of the major, trace, and rare earth elements (REEs). The plant and soil samples were c...

Calcium is an essential macronutrient for plants and animals and plays an indispensable role in structure and signaling. Low dietary intake of calcium in humans has been epidemiologically linked to various diseases which can have serious health consequences over time. Major staple food-grains are poor source of calcium, however, finger millet [Eleusine coracana (L.) Gaertn.], an orphan crop has...

phytoremediation is a technology that uses plants for the remediation of the contaminated soils, sediments, tailings, and groundwaters. in this work, the ability of trifoliumalexanderium for the phytoremediation of the tailings soil in the anjir-tange coal washing plant was investigated. for this purpose, trifolium sp. was cultivated in three soils consisting of the tailings dam, an agricultura...

The redox balance of inorganic sulfur in heavily polluted rivers might be disrupted, making reduction a major metabolic pathway sulfate-reducing bacteria (SRB), leading to massive accumulation S2− and blackening the water bodies. A mixed culture microbial consortium (MCMC) Citrobacter sp.sp1, Ochrobactrum sp.sp2, Stenotrophomonas sp.sp3 was used activate native sulfate-oxidizing (SOB) augment o...

background: mercury (hg) is a hazardous metal responsible for environmental contamination and human intoxication. methyl mercury bio-accumulation through food chain can be responsible for chronic mercury exposure of south caspian sea communities with a diet rich in fish. uncertainties about exposure levels that could have damaging consequences for nervous system development of infants makes bio...
