Soil pollution in urban areas can derive from contaminants released from point or diffuse sources. As defined in the glossary, point-source pollution arises from discernible, confined and discrete source from which contaminants are discharged.
27 de mar. de 2023 · Liu et al. demonstrate that human-driven soil contamination in natural areas mirrors that in nearby urban greenspaces globally, and highlight the potential influence that soil contaminants...
As the world continues to urbanize, however, humans have lost contact with soil and the services it provides to sustain life. A review of the literature shows that the ability of urban activities to influence the physical conditions and pollution levels in soils at a distance is increasing.
27 de abr. de 2021 · We study impacts of urbanization on future river pollution taking a multi-pollutant approach. We quantify combined point-source inputs of nutrients, microplastics, a chemical (triclosan) and a...
Urbanization, and industrial exhausts, are the main causes of high levels of pollution. Ecological risk showed that metals in urban soils pose a slight to highest environmental risk with mercury and Cd pose the highest ecological risk.
9 de mar. de 2022 · The results on the pollution index indicate a widespread intensification of soil pollution in urban soils across all studied heavy metals.
We propose that future urban soil pollution work that engages at higher levels of the SCEO and employs USDN HIPs, will be more effective at addressing crucial environmental health challenges by supporting community-based, equitable, inclusive, and sustainable solutions.
