Randomized trial examines soil contaminant levels in natural areas and urban greenspaces, indicating shared human impacts.

This research aims to understand the similarities in soil contamination levels between urban greenspaces and natural ecosystems worldwide.
Analyzed soil samples from urban greenspaces and adjacent natural areas globally.
Measured levels of contaminants including metal(loid)s, pesticides, microplastics, and antibiotic resistance genes.
Explored the influence of socio-economic factors on soil contamination levels.
Urban greenspaces and natural areas showed similar levels of multiple soil contaminants.
Human influences accounted for various forms of soil contamination (p<0.05).
Higher contaminant levels correlated with changed microbial traits related to stress resistance and nutrient cycling.

Liu et al. (2023) studied this question.
