Impact of microplastics on human health and aquatic species
Summary
This review examines the harmful effects of microplastics on marine life and human health, covering physical injury, oxidative stress, and disrupted immune responses in fish and other organisms. Researchers found that these impacts can cascade through marine food webs, affecting biodiversity and ecosystem function. The study also highlights growing concerns about human exposure to microplastics through seafood and other pathways.
Microplastics (MPs) have emerged as a pervasive environmental challenge, with significant implications for both marine ecosystems and human health. This study delves into the adverse effects of MPs, highlighting their physical, chemical, and biological impacts on marine life, particularly fish. These impacts include physical injury, oxidative stress, and altered immune responses, which can have cascading effects on marine biodiversity and ecosystem functionality. The review also underscores the risk MPs pose to humans through direct exposure, via consumption of contaminated seafood, inhalation, or dermal contact, potentially leading to oxidative stress, cytotoxic effects, and disturbances in immune function. By comprehensively examining existing research and identifying knowledge gaps, this study aims to underline the urgent need for targeted research strategies. These strategies should focus on elucidating the complex interactions between MPs and biological systems, assessing long-term health implications, and developing effective mitigation measures. Through detailed analysis of methodologies, results, and existing literature, this review aims to contribute to a deeper understanding of the multifaceted impact of microplastics, thereby guiding future research directions and informing policy decisions for the protection of marine ecosystems and human health.
