Plastics are now omnipresent in our daily lives. The existence of microplastics (1 µm to 5 mm length) and possibly even nanoplastics (<1 μm) has recently raised health concerns. In particular, believed be more toxic since their smaller size renders them much amenable, compared microplastics, enter the human body. However, detecting imposes tremendous analytical challenges on both nano-level sensitivity plastic-identifying specificity, leading a knowledge gap this mysterious nanoworld surrounding us. To address these challenges, we developed hyperspectral stimulated Raman scattering (SRS) imaging platform with an automated plastic identification algorithm that allows micro-nano analysis at single-particle level high chemical specificity throughput. We first validated enhancement narrow band SRS enable high-speed single nanoplastic detection below 100 nm. then devised data-driven spectral matching imposed by sensitive narrow-band achieve robust determination common polymers. With established technique, studied plastics from bottled water as model system. successfully detected identified major types. Micro-nano concentrations were estimated about 2.4 ± 1.3 × 10

From oceans to dinner plates: The impact of microplastics on human health

Heliyon, Год журнала: 2023, Номер 9(10), С. e20440 - e20440

Опубликована: Сен. 26, 2023

Microplastics, measuring less than 5 mm in diameter, are now found various environmental media, including soil, water, and air, have infiltrated the food chain, ultimately becoming a part of human diet. This study offers comprehensive examination intricate nexus between microplastics health, thereby contributing to existing knowledge on subject. Sources microplastics, microfibers from textiles, personal care products, wastewater treatment plants, among others, were assessed. The meticulously examined diverse routes microplastic exposure—ingestion, inhalation, dermal contact—offering insights into associated health risks. Notably, ingestion has been linked gastrointestinal disturbances, endocrine disruption, potential transmission pathogenic bacteria. Inhalation airborne emerges as critical concern, with possible implications for respiratory cardiovascular health. Dermal contact, although explored, raises prospect skin irritation allergic reactions. impacts COVID-19 pollution also highlighted. Throughout manuscript, need deeper mechanistic understanding interactions systems is emphasized, underscoring urgency further research public awareness.

Effects of microplastics, pesticides and nano-materials on fish health, oxidative stress and antioxidant defense mechanism

Frontiers in Physiology, Год журнала: 2023, Номер 14

Опубликована: Июнь 26, 2023

Microplastics and pesticides are emerging contaminants in the marine biota, which cause many harmful effects on aquatic organisms, especially fish. Fish is a staple affordable food source, rich animal protein, along with various vitamins, essential amino acids, minerals. Exposure of fish to microplastics, pesticides, nanoparticles generates ROS induces oxidative stress, inflammation, immunotoxicity, genotoxicity, DNA damage alters gut microbiota, thus reducing growth quality Changes behavioral patterns, swimming, feeding habits were also observed under exposures above contaminants. These affect Nrf-2, JNK, ERK, NF-κB, MAPK signaling pathways. And Nrf2-KEAP1 signalling modulates redox status marinating enzymes Effects found modulate antioxidant enzymes, including superoxide dismutase, catalase, glutathione system. So, protect health from contribution nano-technology or nano-formulations was researched. A decrease nutritional population significantly impacts human diet, influencing traditions economics worldwide. On other hand, traces microplastics habitat water can enter humans by consuming contaminated may result serious hazards. This review summarizes stress caused due nano-particle contamination exposure their impact health. As rescue mechanism, use management disease discussed.
