    Microplastics Originating from Paints and Synthetic Textile Materials
    (Springer Nature Singapore, 2024-04) Moyo, M.; Baloyi, R.B.; Sithole, B.B.; Falayi, T.
    There is continued growth in paints and synthetic textile materials production and consumption due to expanded use of paints in different applications, population growth and fast fashion trends. Paints and synthetic textile materials are some of the major sources of microplastics. The major sources of microplastics originating from paints are marine paints, road markings, architectural paints, and spray painting. Major contributing factors in the release of microplastics from paints to the environment are paint production processes, weathering and abrasion, paint spilling, residual paints on paint application tools and storage containers, paint end of life (EoL) disposal, and paint applicator’s expertise. In the context of synthetic textile materials, major emissions of the microplastics occur during the production processes of the synthetic textile materials, during use and laundering, washing conditions and drying. Studying the role and influence of paints and synthetic textile materials in the generation of microplastics is critical. It helps in coming up with mitigatory measures to reduce the generation of microplastics from paints and synthetic textile materials and hence promotion of sustainability. Devising a holistic approach to research and development of green chemistry and green manufacturing processes in the production of paints and synthetic textile materials is one of the mitigatory measures. Also, developing policies and legislation on wastewater treatment systems for all responsible stakeholders and introducing legislation on do-it-yourself (DIY) painting activities could help in reducing the generation of microplastics from paints and synthetic textile materials.

    Reports on Collection, Identification and Estimation of Microplastic in Freshwater Bodies
    (Springer Nature, 2024-04-27) Falayi, T.; Musiyarira, H.; Sithole, T.; Moyo, M.
    Microplastics (MP) are plastic materials whose particle size is less than 5 μm. MP are pervasive and are an emerging threat to fauna and flora. MPs are now being found in fresh water sources and this has a threat on the wellbeing of human beings. To properly manage the pollution problem of MP, the collection, identification, and estimation of MPs in freshwater is important. The methods described should be robust with very low estimates of uncertainty. This chapter, therefore, takes a systematic review of the current and advances in the identification, collection and estimation of MPs in freshwater. The use of non-validated marine methods for freshwater analysis is problematic. The expensive nature of some of the MPs detection method render the monitoring of MPs in resource challenged countries a problem.
