Summary
This 2024 review consolidates peer-reviewed evidence on how atmospheric particulate deposition influences phytoplankton dynamics across marine and freshwater ecosystems. The authors examine dual pathways of impact: physical effects including light attenuation and particle sedimentation, alongside biogeochemical mechanisms such as nutrient and trace metal inputs from atmospheric sources. The synthesis suggests that atmospheric inputs from dust, industrial and anthropogenic sources meaningfully shape aquatic primary productivity and phytoplankton community structure, though the relative importance of these pathways may vary by ecosystem type and deposition source.
UK applicability
The findings are relevant to UK marine and freshwater management, particularly as atmospheric dust and industrial emissions continue to influence coastal and inland water bodies. However, UK-specific studies may be limited; the review's generalisations across global ecosystems may require contextualisation for northern temperate conditions and current air quality regulations.
Key measures
Phytoplankton biomass, primary productivity, community composition, light penetration, nutrient concentrations (nitrogen, phosphorus), trace metal availability, sedimentation rates
Outcomes reported
The review synthesises mechanisms by which atmospheric particulate matter (dust, industrial emissions, anthropogenic sources) affects phytoplankton dynamics, primary productivity, and community composition in marine and freshwater systems. The authors examine both direct physical effects (light attenuation, sedimentation) and biogeochemical pathways (nutrient and trace metal inputs).
