The plastic related research has been an epicentre in recent times. The presence and spread of micro (nano) plastics (MNPs) are well-known the terrestrial aquatic environment. However, focus on fate remediation MNP soil groundwater is limited. bioaccumulation ingested MNPs remain unknown within digestive tract animals. There also a significant knowledge gap understanding ubiquitous organic environmental pollutants with biological systems. Reducing consumption, improving waste management practices, developing environmentally friendly alternatives some key steps needed to address pollution. For better handling protect environment from these invisible substances, policymakers researchers urgently need monitor map contamination groundwater.

Biosensors, Journal Year: 2025, Volume and Issue: 15(1), P. 44 - 44

Published: Jan. 13, 2025

Plastic pollution, particularly from microplastics (MPs) and nanoplastics (NPs), has become a critical environmental health concern due to their widespread distribution, persistence, potential toxicity. MPs NPs originate primary sources, such as cosmetic microspheres or synthetic fibers, secondary fragmentation of larger plastics through degradation. These particles, typically less than 5 mm, are found globally, deep seabeds human tissues, known adsorb release harmful pollutants, exacerbating ecological risks. Effective detection quantification essential for understanding mitigating impacts. Current analytical methods include physical chemical techniques. Physical methods, optical electron microscopy, provide morphological details but often lack specificity time-intensive. Chemical analyses, Fourier transform infrared (FTIR) Raman spectroscopy, offer molecular face challenges with smaller particle sizes complex matrices.

Impacts of micro- and nanoplastics on early-life health: a roadmap towards risk assessment

Microplastics and Nanoplastics, Journal Year: 2024, Volume and Issue: 4(1)

Published: July 2, 2024

Abstract Micro- and nanoplastics (MNPs) are ubiquitous environmental pollutants representing a concern for human health. MNPs have been detected in placentas, indicating that during pregnancy maternal exposure may lead to placental transfer foetal exposure, with potential adverse effects on early-life development. However, comprehensive risk assessment (RA) framework, specific is lacking. Here, we propose novel roadmap assist the development of an health RA MNPs. This designed based established chemical, mixture, particle, MNP strategies aligned standard components (problem formulation, hazard identification, characterisation, assessment, characterisation). We systematically work through these stages identify what needed progress impacts MNPs, including information missing, be used interim. While challenges such as complex physicochemical properties limited toxicity data at relevant levels, uncertainties related characterising exposures described elsewhere, our discusses how specifically impact significance presence biological samples factors influencing bioaccumulation transfer. Additionally, introduce new technology readiness levels methods detection matrices. Importantly, this review integrates broad scope into one document, providing unified resource. highlight requirements areas targeted research, dose-response relationships assessing By addressing gaps, aims advance robust ultimately enhancing understanding mitigation risks associated

Microplastics in maternal blood, fetal appendages, and umbilical vein blood

Ecotoxicology and Environmental Safety, Journal Year: 2024, Volume and Issue: 287, P. 117300 - 117300

Published: Nov. 1, 2024

Microplastics (MPs) have been detected in placenta and amniotic fluid, but there is no research on whether MPs exist the other two fetal appendages: membrane umbilical cord. Additionally, existence of vein blood remains unexplored. Furthermore, it unclear maternal are associated with those appendages. In this study, we selected 12 full-term pregnant people who delivered by cesarean section, finally 16 kinds from blood, appendages, laser direct infrared (LDIR). Polyamide accounted for highest proportion six samples, followed Polyurethane. The total median abundance samples were cord, membrane, high to low, specific values 10.397 particles/g, 8.176 6.561 4.795 4.675 2.726 particles/g respectively. Moreover, more than 90 % measured between 20 100 μm diameter. We also found that fluid increased increase age (R=0.64, p=0.025) body mass index before pregnancy (r = 0.59, p= 0.049). However, statistically significant association was lifestyle factors abundance. Future studies should aim expand sample size further investigation.
