Subject:
bioavailability; breathing; copper; gastrointestinal system; humans; ingestion; leaching; lead; pH; risk; zinc
Abstract:
... The objective of this study was to provide insight into human exposure to trace contaminants bearing red mud, derived precipitates and geopolymeric blocks due to inhalation contact and/or hand-to-mouth ingestion. The in vitro bioaccessibility behavior of trace contaminants was investigated with the PBET (physiologically based extraction test), ALF (artificial lysosomal fluid) and MGS (modified Gam ...

adsorption; anions; bioavailability; bottom ash; chlorides; cities; exposure pathways; gastrointestinal system; heavy metals; hospitals; humans; leaching; ligands; nitrates; pH; rare earth elements; sulfates; toxicity; waste incineration; China
Abstract:
... Leaching behavior and gastrointestinal bioaccessibility of rare earth elements (REEs) from hospital waste incineration (HWI) fly and bottom ash samples collected from Beijing and Nanjing Cities were assessed. In the same ash sample, the leaching concentrations of individual REEs determined by the Toxicity Characteristic Leaching Procedure (TCLP) were higher than those detected by the European stan ...

Subject:
Dehalococcoides; aroclors; bioaccumulation; bioremediation; biphenyl; dechlorination; food chain; humans; lactic acid; quantitative polymerase chain reaction; salts; toxicity
Abstract:
... The toxic and recalcitrant polychlorinated biphenyls (PCBs) adversely affect human and biota by bioaccumulation and biomagnification through food chain. In this study, an anaerobic microcosm was developed to extensively dechlorinate hexa- and hepta-CBs in Aroclor 1260. After 4 months of incubation in defined mineral salts medium amended PCBs (70 mmol·L–¹) and lactate (10 mmol·L–¹), the culture dec ...

acidity; aerosols; alkalinity; biomass; carbon; carbon dioxide; carbon sinks; carbonates; desertification; deserts; dust; emissions; global warming; humans; ice; marine ecosystems; nutrients; oceans; phytoplankton; rain; sand; seawater; semiarid zones; society; storms; vegetation
Abstract:
... Dust and Sand Storms (DSS) originating in deserts in arid and semi-arid regions are events raising global public concern. An important component of atmospheric aerosols, dust aerosols play a key role in climatic and environmental changes at the regional and the global scale. Deserts and semi-deserts are the main source of dust and sand, but regions that undergo vegetation deterioration and deserti ...

Abstract:
... Exploration of heavy metals and organic pollutants, their leaching capacity along with health and environmental risks in contaminated industrial construction and demolition waste (ICDW) within a pesticide manufacturing plant were investigated. A maximum content of 90.8 mg•kg–¹ Cd was found present in the wastes, which might originate from phosphorus rocks and industrial sulfuric acid used in pesti ...
