KH2PO4—cement is used to soildify/stabilize the Pb contaminated soil. Leaching tests are conducted to study the leaching characteristics and mechanism of Pb in solidified bodies under acid rain soaking, and the effects...

Wireless Sensor Networks (WSNs) are extensively used in applications such as environmental monitoring, surveillance, and smart security, but their performance is limited by the restricted energy capacity of sensor nodes,...

The previous studies show that acid rain pH significantly affects the leachability of stabilized heavy metals-contaminated soils. The parameters of diffusion coefficient (De) and retardation factor (Rd) are critical for ...

Abstract The productivity decline of technological wells during in situ leaching (ISL) is primarily associated with clogging of well filters and the near-filter zone, leading to a significant increase in hydraulic resist...

In the Northern Patagonian Andes, the austral beech Nothofagus pumilio dominates the upper limit of the temperate forest and is an important source of allochthonous dissolved organic matter (DOM) in mountain lakes. In ad...

The semi-dynamic leaching tests are conducted to investigate the leaching characteristics of MPC- solidified/stabilized Zn-contaminated soil under the effect of acid rain, and the CEMI groups are added to compare with th...

Grazing reduces grass cover and promotes the dominance of shrubs with high concentration of soluble phenols, which may leach from their canopies and reach neighboring plants and soils. Despite their potential allelopathi...

Las especies de la familia Aeglidae habitan ambientes dulceacuícolas (ríos, lagos, arroyos, lagunas, cavernas) siendo su área de distribución la comprendida por Bolivia, Paraguay, Chile, Brasil, Uruguay y Argentina. ...

Abstract Wireless Sensor Networks comprise low-cost, low-power, lightweight, and multifunctional sensor nodes capable of sensing and transmitting data from remote or hazardous environments to a central base station. Thes...

ObjectiveTo investigate the pollution status of lead （Pb）， cadmium （Cd）， arsenic （As）， mercury （Hg） and chromium （Cr） in Ganoderma lucidum sold in Lishui City and to evaluate the exposure risk o...

Landfill slip will cause losses of lives and properties and serious environmental pollution. At present, the methods for stability of landfills are few. The drainage well to control the stability of the landfill at an in...

The aim of this work is to assess the risk of groundwater contamination associated with BTEX dissolution from fuels as a residual phase. Numerical simulations of sixty scenarios were carried out with the software HYDRUS ...

Abstract The purpose of this study was to evaluate how universal adhesives affected the proliferation of gingival fibroblasts and human dental pulp stem cells by measuring cell viability at different time points: 1 min,...

ABSTRACT White-sand vegetation (campinarana) is a type of vegetation restricted to oligotrophic and highly leached white sand soils in the Amazon phytogeographic domain that includes grassland to forest phytophysiognomie...

Antimicrobial finishings protect users from pathogenic and odor-generating microorganisms, which are of medical and hygiene concerns. Controlled release is a useful approach to obtain antimicrobial finishings in several ...

Biostimulation and bioaugmentation are promising for remediating acid in-situ leaching (AISL) U mine groundwater, yet their efficiencies, mechanisms, and acid stress regulation remain unclear. This study collected ground...

Abstract Background Nanodelivery represents a promising strategy to enhance pesticide efficacy while reducing associated environmental risks. Mesoporous silica nanospheres (MSNs) can serve as effective nanocarriers but i...

Di-(2-ethylhexyl) phthalate (DEHP) is a ubiquitous environmental endocrine disruptor that leaches from polyvinyl chloride products and metabolizes to mono-(2-ethylhexyl) phthalate (MEHP), causing spermatogenic dysfunctio...

Há enigmas e soluções manifestos e latentes no livro de Roberto Cardoso de Oliveira.* E entre eles o supremo enigma da Antropologia, que se pode formular, de maneira muito simples (e até meio simplista), na pergunta ...

Cured-in-place pipe (CIPP) technology is widely used for pipeline rehabilitation, but curing emissions and leachates may introduce complex chemical mixtures into air and drinking water, raising environmental health conce...

Exotic type deposits include several species of minerals, such as atacamite, chrysocolla, copper pitch, and copper wad. Among these, copper pitch and copper wad have considerable concentrations of manganese. However, the...

Mineral-associated organic matter, the dominant form of relatively stable carbon (C) in soil, often co-occurs with reactive iron (Fe) and aluminum (Al) phases across soils. Yet, how organo-metallic associations at the mo...

The materials for medical application are normally consisted of metal, ceramic, and polymer. Each material has its own limitations such as corrosion in metal, the brittleness of ceramic, and the high temperature problem ...
