ABSTRACT This review synthesizes current research on the phytoremediation potential of industrial hemp (Cannabis sativa L.) for heavy metals, including arsenic, aluminium, mercury, copper, lead, cadmium, nickel, and zinc, as well as per‐ and polyfluoroalkyl substances (PFAS), commonly referred to as “forever chemicals.” A structured and transparent ...

Objective Sb deposits are characterized by simple mineral assemblage. The ore-forming ages, sources of ore-forming materials, and genesis of Sb deposits are controversial owing to the absence of suitable minerals for analysis.

Malokarpatské baníctvo do konca 16. storočia / The Little Carpathians Mining until the Late Sixteenth Century [PDF]
The territory of Little Carpathians became well-known mining area due to the ore deposits of precious metals and antimony, as well as due to the pyrite deposits, especially in areas of Pezinok, Limbach, Modra, Pernek, and partially also in other ...

ABSTRACT This study presents multifaceted analyses of metal artefacts from the Jodłowno Hoard (Northern Poland), revealing that the metal originated from Iberian polymetallic ore deposits. Transported as raw ingots via Atlantic maritime routes, this copper was reworked locally into regionally distinctive forms.

ABSTRACT This study presents the results of an interdisciplinary investigation of 98 tin–lead sewn tokens from 13th‐century Gdańsk, the largest assemblage of its kind in Central Europe. Combining archaeological context, typology, SEM‐EDS and lead isotope analysis, the research explores provenance, production and function.

Heavy metals and nitrogen in mosses: spatial patterns in 2010/2011 and long-term temporal trends in Europe [PDF]
Naturally-occurring mosses have been sampled across Europe to monitor the deposition of heavy metals and nitrogen from the air. This survey has been repeated at five-yearly intervals since 1990 for heavy metals and since 2005 for nitrogen.

Atomistic Understanding of 2D Monatomic Phase‐Change Material for Non‐Volatile Optical Applications
Antimony is a promising monatomic phase‐change material. Scaling down the film thickness is necessary to prolong the amorphous‐state lifetime, but it alters the optical properties. The combined computational and experimental study shows that, as thickness decreases, the extinction coefficient and optical contrast are reduced in the near‐infrared ...

This study focuses on phytoremediation in a gold mining‐contaminated area in Doko, Guinea. Plant, soil, and rhizospheric soil samples were collected and subjected to physicochemical analyses to quantify heavy metal content. Biological indicators: bioconcentration factor (BCF), translocation factor (TF), and biological accumulation coefficient (BAC ...
