“…Mikroplastiklerin sedimandan ayrılması konusunda çeşitli yöntemler kullanılmaktadır [61]. Bu çalışmada plastiklerin gözle ve mikroskop altında görülenlerinin penset ile ayrılması; bu yöntemle ayrılamayanların ise saf su ve tuzlu su çözeltisinde yüzdürme (flotasyon) yöntemi ile ayrılmasına çalışılmıştır.…”

Günlük hayatta önemli bir yere sahip olan plastikler, fiziksel bozunmaya uğradıklarında kolaylıkla taşınarak göllere, akarsulara, denizlere, dağlara ve topraklara ulaşmakta ve kirletici olarak tüm doğal ekosistemlere zarar vermektedirler. Mikroplastiklerin özellikle kıyı alanlarında birikimini etkileyen en önemli unsurlardan ilki jeolojik süreçlerden olan karasal ve denizel sedimanların taşınımları ikincisi ise antropojenik etmenlerdir. Muğla kıyı sedimanlarında biriken mikroplastik miktarını belirlemek amacıyla Palamutbükü, Datça, Marmaris ve Akyaka sahil kumlarından alınan örnekler tane boyu bakımından karakterize edilmiş; düşük yoğunluklu mikroplastik ayırma yöntemleri kullanılmıştır. Plastik içeriği sırasıyla; Palamutbükü örneğinde 11 adet meso-makro plastik, 56 adet mikroplastik / 50 g, Datça örneğinde 13 adet meso-makro plastik, 33 adet mikroplastik / 50 g, Marmaris örneğinde 13 adet meso-makro plastik, 143 adet mikroplastik / 50 g, ve Akyaka örneğinde 4 adet meso-makro plastik, 59 adet mikroplastik / 50 g olarak belirlenmiştir. Orta kum boyunda, incelenen örnekler içinde en küçük ortalama tane boyutuna sahip Akyaka sahili örneği meso-makroplastik içeriği en düşük olandır. İnce çakıl ortalama tane boyuyla en kaba ortalama tane boyuna ve en yüksek çakıl yüzdesine sahip Datça örneği ise mikroplastik sayısı en düşük örnektir. Lif ve parça formunda plastik parçalarında Fourier Dönüşümlü Kızıl Ötesi Spektrometresi analizi gerçekleştirilmiştir. Mikroplastiklerin bileşimlerinde selülöz, polietilen ve polipropilen olduğu belirlenmiştir.

“…Likewise, the use of synthetic chemicals for remediation in MP-contaminated areas is a less appealing technique because of its complexity, non-green character, and polymer and environmental variability. As a result, given the environmental hazard posed by MPs, there are urgent needs to create cost-effective and ecologically sustainable remediation techniques [11]. However, Arbabi et al [74] stated that various methods have been applied to remove MPs from the environment, such as replacing microbeds in ocean water with natural materials and using fewer plastic materials.…”

“…Plastic particles in soil can be degraded by a variety of bacteria, fungi, and algae [84]. It is widely recognized that only some microbes can breakdown MPs, while some others may be discovered, and only some enzymes play a specialized role in the biodegradation of MP when the polymer type is unknown [11,84]. It has been demonstrated, for example, that the bacterial stain 201-F6 (Ideonella sakaiensis) produced enzymes like PETase and MHETase, which hydrolyze PET to an eco-friendly monomer [84].…”

“…Examples of the most prominent microbial strains reported for degrading plastic polymers include Paenibacillus sp., Oscillatoria subbrevis, Pseudomonas aestusnigri, Corynebacterium sp., Bacillus sp., Aureobasidium pullulans, Enterobacter sp., Pseudomonas geniculate, Aspergillus fumigatus, Bacillus niacin, Agromyces sp., Aspergillus fumigatus, Pseudomonas stutzeri, Comamonas acidovorans, Comamonas acidovorans TB-35, Streptomyces badius, Arthrobacter paraffineus, Microbacterium paraoxydans, Micrococcus luteus, Phanerochaete chrysosporium, Cladosporium sphaerospermum, and Penicillium chrysogenum [85]. Biotechnology is a new bioremediation method that is gaining popularity [11]. Microbial degradation is a practical and cost-effective method of removing MP pollutants [86].…”

“…Every year, 381 million tons of plastic waste are produced globally (only 5-9% of that has been recycled). Of that, 38 million tons are generated by the US alone [9,10], and 15 and 32% of global plastic production in 2020 was accounted for by Europe and China, respectively [11]. Shopping bags are robust, inexpensive, and lightweight plastic goods that are frequently utilized on a worldwide scale.…”

Microplastic (MP) pollution is a widespread global environmental concern, representing an emerging contaminant with major implications for ecosystems and human well-being. While extensive research has focused on MPs in aquatic environments, their impact on sediments and soils remains inadequately explored. Studies have confirmed the harmful effects of MPs on soil and sediment biota, as well as on the properties of these ecosystems. Furthermore, the long-term persistence of MPs within the environment contributes to their accumulation in terrestrial and marine food chains, with potential consequences for groundwater quality. Although several methods have been applied to mitigate MP pollution, some methods have drawbacks and some are not studied well, necessitating the urgent exploration of novel, sustainable, and eco-friendly approaches. Biochar is a remarkable solution for pollution removal; recently it has been used in addressing the increasingly concerning issue of microplastic contamination. This review aims to shed light on the difficulty posed by MPs in soils and sediments, while highlighting the remediation methods and the potential advantages of utilizing BC as an environmentally friendly solution for MP removal and remediation.
