Large-scale monitoring and risk assessment of microplastics in the Amazon River

Water Research, Год журнала: 2023, Номер 232, С. 119707 - 119707

Опубликована: Фев. 5, 2023

Microplastics (MPs) are one of the most widespread contaminants worldwide, yet their risks for freshwater ecosystems have seldom been investigated. In this study, we performed a large monitoring campaign to assess presence and MPs in Amazonian ecosystems. We investigated MP pollution 40 samples collected along 1500 km Brazilian Amazon, including Amazon River, three major tributaries, several streams next important urban areas. 55-5000 µm size range were characterized (size, shape, color) by microscopy identified (polymer composition) infrared spectroscopy. Ecotoxicological assessed using chronic Species Sensitivity Distributions effects triggered food dilution tissue translocation data alignment methods that correct polydispersity environmental bioaccessibility. This study shows ubiquitous ecosystems, with measured concentrations (55-5000 µm) ranging between 5 152 MPs/m3 River its main 23 74,550 streams.

Microplastics in the Amazon biome: State of the art and future priorities

Heliyon, Год журнала: 2024, Номер 10(7), С. e28851 - e28851

Опубликована: Март 30, 2024

Microplastics (MPs) have been identified as a major potential threat to the biota and human health. Despite exponential increase in MP research worldwide, few studies focused on extensive Amazon biome. To assess priorities, present study reviewed summarized available scientific knowledge MPs Amazon, addition analyzing population waste-management data, evaluate sources of hydrographic system. Poor sanitation conditions are main source for vast basin, and, consequently, adjacent ocean. Secondary predominated, mostly fibers (96% debris), composed polyamide (32%).

Analysing micro- and nanoplastics with cutting-edge infrared spectroscopy techniques: a critical review

Analytical Methods, Год журнала: 2024, Номер 16(15), С. 2177 - 2197

Опубликована: Янв. 1, 2024

The escalating prominence of micro- and nanoplastics (MNPs) as emerging anthropogenic pollutants has sparked widespread scientific public interest. These minuscule particles pervade the global environment, permeating drinking water food sources, prompting concerns regarding their environmental impacts potential risks to human health. In recent years, field MNP research witnessed development application cutting-edge infrared (IR) spectroscopic instruments. This review focuses on advanced IR techniques relevant instrumentation analyse MNPs. A comprehensive literature search was conducted, encompassing articles published within past three years. findings revealed that Fourier transform (FTIR) spectroscopy stands most used technique, with focal plane array FTIR (FPA-FTIR) representing cutting edge in spectroscopy. second popular technique is quantum cascade laser (QCL-IR) spectroscopy, which facilitated rapid analysis plastic particles. Following closely optical photothermal (O-PTIR) can furnish submicron spatial resolution. Subsequently, there atomic force microscopy-based (AFM-IR) made it feasible MNPs at nanoscale level. instruments identified covered this were compared. Comparison metrics encompass substrates/filters, data quality, resolution, acquisition speed, processing cost. limitations these identified, recommendations address proposed. offer valuable guidance researchers selecting suitable for experiments, thereby facilitating advancements aimed enhancing our understanding health associated
