- Bioaccumulation and Trophic Transfer of Heavy Metals in Marine Fish . . .
Heavy metal contamination in marine ecosystems poses a critical environmental challenge, with significant implications for biodiversity, trophic dynamics, and human health Marine fish are key bioindicators of heavy metal pollution because of their role in food webs and their capacity for bioaccumulation and trophic transfer This review synthesizes current knowledge on the pathways and
- Comparative Study of the Presence of Heavy Metals in Edible . . . - MDPI
Currently, the processes of obtaining and producing food as well as consumption habits give rise to new challenges for food safety The presence of heavy metals in edible vegetable oils has harmful effects for humans In this study, the scientific literature which reports the presence of heavy metals in different types of vegetable oils was analysed More than 25 heavy metals are evaluated in
- Assessment of Heavy Metals in Surface Waters of the Santiago . . . - MDPI
The Santiago–Guadalajara River Basin has an area of 10,016 46 km2 The Metropolitan Area of Guadalajara, within the basin, is the second-largest city in the country, with more than 5 million inhabitants The growth of the urban population, as well as industrial and agricultural activities with insufficient infrastructure for the sanitation of wastewater and its reuse, have caused
- Corrosion and Protection of Metals - MDPI
During the last few decades, an enormous effort has been made to understand corrosion phenomena and their mechanisms, and to elucidate the causes that dramatically influence the service lifetime of metal materials The performance of metal materials in aggressive environments is critical for a sustainable society The failure of the material in service impacts the economy, the environment
- Clay-Based Materials for Heavy Metals Adsorption: Mechanisms . . .
Given the severe threats posed by heavy metal pollution to ecological environments and human health, developing effective remediation technologies is of paramount importance This review delves into the mechanisms, recent advancements, and future prospects of clay mineral-based materials in the adsorption of heavy metals Clay minerals such as kaolinite, montmorillonite, and bentonite have
- Immobilization of Heavy Metals in Biochar Derived from Biosolids . . .
Slow pyrolysis was carried out in biosolids under three different temperatures (400, 500 and 600 °C) and two different carrier gases (CO2 and N2) on a fluidized bed reactor The total concentration, chemical fractionation, and plant availability of the heavy metals in biochar were assessed by standard methods The total concentration of Fe, Zn, Cu, Mn, Cr, Ni and Pb increased with the
- Combustion of Metals in Oxygen-Enriched Atmospheres - MDPI
Metal combustion is one of the main issues threatening service safety in oxygen-enriched atmospheres, leading to unexpected explosions in rocket engines This paper reviews the recent development of metals combustion in oxygen-enriched atmospheres Test methods under three typical conditions and combustion behaviors of three typical metals are mainly discussed The microstructures of the
- Heat Treatment of Metals - MDPI
Merlin et al (Contribution n 2) focuses on post-fabrication heat treatment (PFHT) as a tool aimed to target microstructure and mechanical properties of components produced by additive manufacturing They report that in 17-4 PH martensitic stainless steel PFHT promotes the formation of precipitates rich in cupper and of niobium particles Authors describe how PFHTs act on the properties of 17
