Insights into wind-driven heavy metal pollution and human health risk assessment in a typical lead-zinc mining area of northern China
Published 2025-07-01“…The results of contamination factor (CF), pollution load index (PLI) and geo-accumulation index (Igeo) indicated that heavy metals in most soils exhibited non-polluted level or slight pollution level, though localized severe contamination by As, Cd, Pb, and Zn was observed. Spatial distribution analysis demonstrated similar dispersion patterns for As, Cd, Pb, and Zn, with wind-mediated transport extending up to 2.0 km from contamination sources. …”

Estimation of the aboveground carbon stocks based on tree species identification in Saihanba plantation forest
Published 2025-04-01“…The most obvious enhancement in the identification accuracy of Spruce (Picea asperata Mast.) was evident, with a notable increase in PA from 38.0% to 55.7%, signifying a substantial 17.7% rise; 2) The dominant tree species in Saihanba exhibited distinct spatial patterns. White Birch (Betula platyphylla Sukaczev) was primarily distributed in the Yinhe Forest in the east, Mongolica (Quercus mongolica Fisch) was predominantly concentrated in the Dahuanqi Forest in the south, Pinus (Pinus sylvestris var. mongholica Litv.) was mainly distributed in the west, the Sandaohekou Forest and the Qiancengban Forest, and Larch were found throughout the entire region. 3) In conjunction with the findings of tree species identification via the gridding estimation approach, it became evident that the aggregate aboveground carbon stocks of each dominant tree species within the Saihanba Mechanical Forestry region amounts to 3313.28 thousand tons. …”
