Assessment of trace metal and rare earth elements contamination in rivers around abandoned and active mine areas. The case of Lubumbashi River and Tshamilemba Canal, Katanga, Democratic Republic of the Congo

Distribution and source of rare earth elements in PM2.5 in Xiamen, China

“…Rare earth elements are commonly divided into light REEs (LREEs), which include La, Ce, Pr, Nd, Pm, Sm, and Eu, and heavy REEs (HREEs), which include Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Sc, and Y . The compositions and distribution patterns of REEs are not influenced by weathering, transportation processes, sedimentation, and diagenesis; thus, the provenance information carried by REEs remains essentially unchanged, so they are generally used to trace material sources . Rare earth element ores are widely used in chemical production and metallurgy as well as the treatment of diseases , and as these industries develop, REE levels will certainly increase in the soil, water, and air.…”

Speciation and Spatial Distribution of Trace Metals in Sediments Around Gold Mining Areas in Northern Côte D’Ivoire

“…The sediments, previously gently crushed in an agate mortar, were carefully weighed and transferred to the highest part of a series of sieves. A 63 μm sieve was placed at the bottom of the sieve stack and care was taken using a pan under the finest sieve to capture the last fine material likely to pass (Atibu et al 2016). 5 1.3.…”

Potential Anthropogenic Pollution of High-technology Metals with a Focus on Rare Earth Elements in Environmental Water

“…Various studies for heavy metals in environmental waters such as rivers, lakes, and coastal seawater has been performed not only for concentration, [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] but also for speciation, [27][28][29] environmental toxicology, [30][31][32][33][34] and assessment of aquatic ecosystem. [35][36][37] In recent years, utilization of high technology metals such as rare earth elements (REEs), whose abundance are extremely low in the earth, has rapidly increased with development of new types of industrial materials and pharmaceutical products. 38,39 In pollution may occur.…”
