Occurrence, Distribution, and Extraction Methods of Microplastics in Marine Organisms | Chapter 8 | Research Advances in Environment, Geography and Earth Science Vol. 4

This study provides a comprehensive overview of the occurrence, distribution, and extraction methods of microplastics in marine organisms to present current data on the presence and distribution of microplastics in marine environments worldwide in a bid to understand the extent of microplastics pollution and their potential effects in marine ecosystems while discussing the pros and cons of different extraction methods of MPs in marine organisms. The widespread presence of microplastics in marine environments has become a significant concern. This chapter reviews the pressing issue of microplastic pollution, its impact on ecosystems, and potential human health risks. Specifically, it addresses the urgent issue of microplastic pollution in marine ecosystems and its potential ramifications for both the environment and human health, providing an overview of the current status of microplastic prevalence, distribution, and extraction methods within marine organisms. Microplastics are recognized as a major environmental problem due to their detrimental effects on ecosystems and their potential risks to human health. These particles enter marine environments through runoff and atmospheric deposition, contaminating beaches and posing threats to marine life. The proliferation of microplastics in aquatic environments represents a multifaceted and pressing environmental challenge. Its repercussions extend well beyond immediate marine ecosystems, impacting the entire ecological food chain and potentially posing risks to human health. Despite the seriousness of this issue, research on the prevalence and distribution of microplastics in marine organisms remains limited. This review seeks to fill this knowledge gap by thoroughly examining the prevalence, distribution, and various extraction methods used to detect microplastics in marine organisms. It stresses the urgent need for targeted measures to manage microplastic pollution, highlights the significant role of human activities in exacerbating this problem, and emphasize the importance of reducing human-induced pollution to protect marine ecosystems. While this review enhances our understanding of microplastic pollution in marine environments and emphasizes the critical need for action to safeguard marine organisms and preserve our oceans for future generations, it also highlights that effectively addressing the microplastic issue requires a well-coordinated approach. This approach should involve research initiatives, policy adjustments, public engagement, and innovative technologies. Crucially, prompt and decisive actions are necessary to counteract the growing threat posed by microplastics to the oceans and the global environment.

Potential Application of Chitosan from Fishery Waste | Chapter 10 | Current Innovations in Chemical and Materials Sciences Vol. 4

 Chitosan is a cationic polysaccharide composed of β-1,4-linked glucosamine units, featuring hydroxyl and amino groups throughout its chain. This polymer is derived from the deacetylation process of chitin and is known for its non-toxic and biocompatible properties. It is commonly employed as an antimicrobial and antioxidant agent. One intriguing aspect of chitosan is its sustainable sourcing. Waste materials from the fishing industry, including shrimp shells, crab shells, squid bones, and fish scales, can be utilized for efficient chitosan production, reducing environmental impact, and providing a renewable source. The extraction of chitosan can be achieved through chemical or biological (enzymatic) methods. Chemical methods involve the use of strong acids or bases, whereas enzymatic methods utilize specific enzymes to break down chitin into chitosan. The choice of extraction method depends on the desired characteristics and application requirements. Chitosan finds applications in various sectors. In cosmetics, it provides moisturizing and skin rejuvenation properties. In pharmaceuticals and biomedical fields, it is used in tissue engineering, wound healing, and drug delivery systems. The food industry benefits from chitosan's antimicrobial and antioxidant properties for food preservation, packaging, and other applications. Chitosan also shows promise in agriculture as a biopesticide and plant growth enhancer. In summary, chitosan is a versatile biomaterial with remarkable properties and numerous applications. Its non-toxicity, biocompatibility, and sustainable sourcing from fishery waste make it attractive to various industries. Ongoing research continues to explore the extensive potential of chitosan, paving the way for further advancements and innovations in its utilization.
