Abstract
The emergence of microplastics (MPs) pollution as a global environmental concern has attracted significant attention in the last decade. The majority of the human population spends most of their time indoors, leading to increased exposure to MPs contamination through various sources such as settled dust, air, drinking water and food. Although research on indoor MPs has intensified significantly in recent years, comprehensive reviews on this topic remain limited. Therefore, this review comprehensively analyses the occurrence, distribution, human exposure, potential health impact and mitigation strategies of MPs in the indoor air environment. Specifically, we focus on the risks associated with finer MPs that can translocate into the circulatory system and other organs, emphasizing the need for continued research to develop effective strategies to mitigate the risks associated with MPs exposure. Our findings suggest that indoor MPs impose potential risk to human health, and strategies for mitigating exposure should be further explored.

Abstract
Abstract
Malaysia is one of the largest palm oil producers in the world with a continuous increment in worldwide demand. The palm oil extraction process leaves palm fibre and shell (F&S) as waste. The palm F&S are biomass fuels that have been utilized in many palm oil mills to generate energy through the combustion process. The release of harmful particulates from the combustion process is the main concern in this research. A few studies had shown that the PM2.5 particulate matters cannot be filtered by the Air Pollution Control System (APCS); thus, it can pollute the environment. In this research, the utilization of additives inside biomass fuels is studied. The effect of additives towards the particulate size of the ashes and determination of the best additive are the two main objectives of this research. The proximate and ultimate analysis was done the determine the combustion profile of the samples. The Scanning Electron Microscopy (SEM) analysis was done to determine the size of particulates inside the ashes.
