Microplastics Origins and Risks: A Methodological Protocol for Source Identification, Apportionment, and Environmental Risk Assessment in Ahvaz Metropolis, Iran
AI summary Read the abstract
This protocol paper outlines a methodological framework for investigating airborne microplastic pollution in Ahvaz, Iran, including passive and active sampling, chemical signature tracing, and receptor modeling for source attribution. The proposed approach aims to characterize microplastic identity, size, concentration, and pollution sources in a highly industrialized Iranian city.
Introduction: Airborne microplastics (MPs) pollution poses substantial risks to environmental and human health. This research protocol outlines a framework for investigating airborne MPs in Ahvaz, Iran, with objectives including their identification, characterization, and source attribution using chemical signature tracing and receptor modeling. Methods and Analysis: The study employs a dual approach of passive and active sampling supported by laboratory analysis and multivariate modeling. Sampling locations were selected to represent diverse urban settings, ensuring comprehensive spatial coverage and data reliability. The protocol included meticulous sample collection, volume estimation, and laboratory analysis to ensure the accurate identification and assessment of MPs pollution. Expected Outcomes: This protocol aims to reveal types, distribution, sources, and potential health risks of airborne MPs in Ahvaz. Insights provided strategies to mitigate MPs emissions in urban areas and a foundation for future research.

Source identification and apportionment of ambient air microplastics: a systematic review
AI summary Read the abstract
Researchers reviewed 26 studies on how scientists identify where airborne microplastics come from, finding that methods fall into three categories: statistical receptor models, air trajectory analysis, and machine learning approaches like support vector machines. The review maps the strengths and limitations of each approach, highlighting that source attribution for atmospheric microplastics remains an evolving and incomplete science.
Atmospheric deposition of microplastics in shiraz, iran
AI summary Read the abstract
Researchers measured atmospheric microplastic deposition during successive dry and rainy events over eight consecutive days at six sites in and around Shiraz, Iran, including a remote non-urbanised location. The study found that microplastic abundance and deposition flux increased progressively during dry periods and was similar across urban and remote sites, suggesting widespread atmospheric transport and redistribution of microplastics via rainfall scavenging.
