(2024) Plant Bioindicators in Assessing Air Quality: A Short Review, International Journal of Environment and Pollution Research, 12(2),1-11 ABSTRACT: Air pollution, long recognized as having an adverse impact on health and comfort, is increasing in urban and industrial areas of society at a rate that makes it one of the most pressing environmental problems. Pollution refers to the introduction of harmful substances into the environment, negatively impacting humans and other organisms and contributing to the degradation of the quality of our environment. This paper aims to discuss the identification of certain plant species that can be used as biological indicators in assessing air quality. In this context, the aim of this paper is to analyze several theoretical aspects of biological monitoring and provide a report on the progress of using plants as biological indicators of air quality. This paper aims to describe the most significant aspects of current knowledge in this field, evaluate the applicability of the methodology, and detail its advantages and disadvantages when compared with traditional methods. KEYWORDS: bioindicators, plant, assessing, air quality, short review INTRODUCTION Air pollution is a major concern throughout the universe due to its impact on living and non-living things. Before an area can be said to be polluted, it is necessary to carry out a bottom-up or top-down environmental assessment (Abulude et al., 2021). Air pollution refers to substances in the atmosphere that have the potential to pose a risk to humans and the environment, and these substances can exist as solid particles, liquid droplets, or gases (Manisalidis et al., 2020). Air pollution can be natural or the result of human activities. Air pollution can be classified into two categories, namely primary pollutants and secondary pollutants. Primary air pollutants are substances that are directly emitted in certain processes and are present in the atmosphere in a composition similar to that when the emissions occurred. Examples are ash from volcanic eruptions, carbon monoxide from vehicle exhaust, or sulfur dioxide released by industry. Meanwhile, secondary air pollutants are not released directly into the atmosphere, but
