    Microplastics in multimedia environment: A systematic review on its fate, transport, quantification, health risk, and remedial measures
    (Elsevier B.V., 2023-01-06T00:00:00) Rose, Pawan Kumar; Jain, Monika; Kataria, Navish; Sahoo, Prafulla Kumar; Garg, Vinod Kumar; Yadav, Anoop
    The ever-increasing presence of microplastics in many environmental components has been a cause of worry for humanity due to their small size and potential health risk. Since the last decade, numerous studies have been conducted on the prevalence and dispersion of microplastics. However, at present, there aren't any systematic studies on fate and transport of microplastics that consider multimedia environmental systems and their mitigation measures. Also, there are limited studies on the routes through which humans are exposed to microplastics. In this review, about 380 articles were evaluated to uncover the extent of microplastic fate, transport, and pollution in different environmental components, including soil, freshwater, marine, and atmosphere, as well as its effect on different ecosystems. We gave special attention to understanding many routes and sources of microplastics intended for human consumption and their consequences on human health. Furthermore, we tried to emphasize on the different methods used for sampling, extraction, identification and characterization of microplastics, along with associated benefits and limitations. This study highlighted existing knowledge and gaps in the remediation of microplastics. On this basis, the bottleneck and current challenges have been proposed. � 2023 Elsevier B.V.

    Optimization of cadmium(II) removal from water using sunflower waste carbon�a statistical approach
    (Taylor and Francis Ltd., 2020-01-28T00:00:00) Jain, Monika; Garg, Vinod Kumar; Paliwal, Rashmi; Kadirvelu, Krishna; Chaudhry, Smita
    In this study, a statistical experimental strategy was used to optimize the Cd(II) adsorption by chemically treated stems of Helianthus annuus (sunflower). The maximum cadmium adsorption was found at 100 mg/L when a dose of 2000 mg/100 ml was applied at pH 6.0. The highest percentage removal obtained using the model was 100%. The F value (17.28), lack-of-fit value (0.09) and coefficient of determination (R 2 = 0.939) established the appropriateness of quadratic model. The results of confirmation experiment, i.e. 99.8% removal of Cd(II) by prepared adsorbent under optimized conditions agreed well with the model predictions. � 2020 Informa UK Limited, trading as Taylor & Francis Group.
