Work was conducted to evaluate the MP accumulating potential and its impact on the biochemical parameters of plants in an urban area (Sambalpur) in India. Four forms of MPs (viz. fiber, fragment, film, and bead) deposited on the leaf surface were analyzed through fluorescence microscopy using the Nile red dye method. Biochemical parameters (ascorbic acid (AA), leaf extract pH (P), total chlorophyll (TC), and relative water content (RWC)) and air pollution tolerance index (APTI) were also determined through standard protocol. The result found the dominance of beads with other MPs in the order: bead (44.7%) > film (27.7%) > fragment (20.7%) > fiber (6.9%) displaying significant spatial and species variation (<i>p</i> < 0.05). Spatially, the MP accumulation on leaf surface followed an order: residence (4.8 count/cm<sup>2</sup>) > sensitive (4.6 count/cm<sup>2</sup>) > urban biotope (4.3 count/cm<sup>2</sup>) > industry (3.3 count/cm<sup>2</sup>) > traffic (2.2 count/cm<sup>2</sup>). Species-wise <i>Ficus benghalensis</i>, <i>Polyalthia longifolia</i>, and <i>Mangifera indica</i> performed reasonably well concerning the MP accumulation while exhibiting good APTI scores. The RWC and leaf extract pH were the most influential factors regulating the MP accumulation. The former was chiefly responsible for dictating the tolerance ability of plants which is corroborated by the principal component and cluster analyses. Thus, it can be ascertained that the plant species offer distinct specificity in MP accumulation which is largely influenced by spatial variations, relative water content, and APTI value of plants.</p>","PeriodicalId":7458,"journal":{"name":"Air Quality, Atmosphere & Health","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142205971","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A cubic quartz glass container with a side length of 450 mm was used, and SO<sub>2</sub> gas was injected into the container from a steel cylinder. Two IDOASs were used to collect spectral data on the vertical plane. The Differential Optical Absorption Spectroscopy (DOAS) algorithm was employed to retrieve the slant column densities (SCDs). The gas distribution in the gas container was estimated with the help of linear fitting. It was found that the experimental SCDs were in good agreement with the theoretical analysis. Based on the sparse gradient of the gas distribution in the gas container and the non-negative of the gas concentration, a CT algorithm called ABOCS-TVM with total variational (TV) regularization was introduced. Numerical simulations show that if the gas in the container is uniform, the algorithm works well even under the influence of perturbations, and the artifacts in the reconstructed images are suppressed. The experiment showed that the algorithm is able to accurately locate the SO<sub>2</sub> gas and provide an approximate distribution. In particular, the reconstructed peak molecular number density is approximately 11% higher than the theoretical value.
