This study examines the concentration, distribution, and characteristics of suspended microplastics (MPs) across various indoor environments in Malaysia, including offices, classrooms, landed homes, and apartments. Over a six-week period, MPs were collected using a vacuum pump and analyzed through gravimetric analysis, stereomicroscopy, and Raman spectroscopy. The results revealed significant variability in MPs concentrations among different locations, with fibers identified as the predominant morphological type. The average counts of MPs in the respective environments were found to be 599 ± 182 in offices, 399 ± 52 in classrooms, 505.17 ± 203.78 in apartments, and 515 ± 134 in landed homes. Statistical analysis indicated no significant differences in MPs counts across the sampled locations. Fibers were consistently the most prevalent shape, followed by films and foams. The MPs were predominantly transparent, with sizes ranging from 101 to 500 μm. Notably, the estimated daily intake (EDI) of MPs was significantly higher in residential settings compared to offices and classrooms, raising potential health concerns regarding prolonged exposure. These findings underscore the pervasive presence of MPs in the Malaysian indoor environment and emphasize the urgent need for further research to identify their sources, assess health impacts, and develop effective mitigation strategies.

Integrating the quintuple helix approach into atmospheric microplastics management policies for planetary health preservation

2024 , M. Dewika , Kalaimani Markandan , J. Nor Ruwaida , Sara Yasina Yusuf , Anjan Deb , N. Ahmad Irfan , Mohammad Khalid

Microplastic pollution has become a major global environmental issue, negatively impacting terrestrial and aquatic ecosystems as well as human health. Tackling this complex problem necessitates a multidisciplinary approach and collaboration among diverse stakeholders. Within this context, the Quintuple Helix framework, which highlights the involvement of academia, government, industry, civil society, and the environment, provides a comprehensive and inclusive perspective for formulating effective policies to manage atmospheric microplastics. This paper discusses each helix's roles, challenges, and opportunities and proposes strategies for collaboration and knowledge exchange among them. Furthermore, the paper highlights the importance of interdisciplinary research, innovative technologies, public awareness campaigns, regulatory frameworks, and corporate responsibility in achieving sustainable and resilient microplastic management policies. The Quintuple Helix approach can mitigate microplastics, safeguard ecosystems, and preserve planetary health by fostering collaboration and coordination among diverse stakeholders.
