Abstract:
... Metal smelting have brought severe metal(loid)s contamination to the soil. Spatial distribution and pollution source analysis for soil metal(loid)s in an abandoned lead/zinc smelter were studied. The results showed that soil was contaminated heavily with metal(loid)s. The mean of lead (Pb), arsenic (As), cadmium (Cd), mercury (Hg) and antimony (Sb) content in topsoil is 9.7, 8.2, 5.0, 2.3, and 1.2 ...

The study by Schulte‐Uebbing et al. (2021) quantified the impact of atmospheric N deposition on C uptake by forests globally, and weighed this climate benefit against the global warming impact of N₂O emissions. A major conclu ...

Whereas, role of mangrove leaves in capturing MPs from tidal water and air were still largely unexplored. Here, we detected the spatial distribution of MPs at both submerged (0.10-0.49 n/cm²) and non-submerged mangrove leaves (0.09-0.24 n/cm²) in the Beibu Gulf. Abundance of MPs on submerged mangrove lea ...
