Morphological and Chemical Characteristics of Microplastics in Surface Water of the Vaal River, South Africa

Environmental Processes, Journal Year: 2024, Volume and Issue: 11(1)

Published: March 1, 2024

Abstract Microplastics research in South Africa has focused on marine and coastal areas, with limited studies reporting microplastics freshwaters. To address this gap, we conducted study to investigate the presence, abundance, physical characteristics, chemical composition of surface water Vaal River, one most important freshwater systems Africa. Twenty-two samples were collected along 60 km middle part river using a 55 μm plankton net. Samples treated by acid digestion, MPs separated density separation. Physical identification was performed Nikon stereomicroscope, identified Raman spectroscopy. observed all 0.13 2.52 particles/m 3 concentrations. ranged size from 0.06 – 4.95 mm, more than 89% less 2 81% fragments (39%) fibers (42%). numerous colours, which green, black, blue dominant, representing 22%, 19%, 18%, respectively. Chemical analysis revealed polymer types as high-density polyethylene (HDPE), polypropylene (PP), low-density (LDPE). In addition, two colourants, pigment yellow 83 carbon detected. This provides new data microplastic occurrence characteristics River system offers baseline for future monitoring. Our findings confirm that is under real threat contamination, could impact its role significant Highlights • prevalent River. Fibrous, small-sized, coloured abundant. Polymers HDPE, LDPE, PP.

Microplastic Abundance and Distribution in the Sediment of Cagayan de Oro River, Philippines

Soil and Sediment Contamination An International Journal, Journal Year: 2024, Volume and Issue: 33(8), P. 1252 - 1268

Published: Jan. 3, 2024

Microplastics (MPs), or plastic particles smaller than 5 mm, are emerging contaminants that potentially affect aquatic species and humans. More research has been undertaken in the marine environment; however, rivers serve as a sink pathways for entering ocean have received less attention. The current study investigated presence of MPs sediments Cagayan de Oro River, one top plastic-emitting listed Philippines. Sediment samples were collected from six sampling stations upstream to downstream using Van Veen grab sampler. Through stereomicroscope Fourier-transform infrared spectroscopy (FTIR), analyzed categorized according color, shape, size, polymer type. All contaminated with ranging 4.4 ± 2.57 33.3 4.44 items/kg. highest density was found close river mouth drains into Macajalar Bay which suggests riverine contributions substantial contributory contamination environments. Prevalent types blue-colored (41%), fiber-shaped 0.5–1.0 mm (43%), polyethylene (43%) particles. Microplastic accumulation is generally higher upstream.

Bioaccumulation, transfer, and impacts of microplastics in aquatic food chains

Journal of Environmental Exposure Assessment, Journal Year: 2024, Volume and Issue: 3(3)

Published: June 18, 2024

Plastics have become a pervasive global contaminant since the mid-20th century, causing harm to organisms at all levels. Preventative measures reduce plastic pollution and awareness-raising campaigns about damaging effects of debris on environment its inhabitants are crucial; however, most assessments focus singular trophic Microplastics, tiny particles ranging from 25 μm 5 mm, emerged as widespread form found in ecosystems worldwide. They can enter directly or through breakdown larger thought be mistaken for food by foraging animals. This leads microplastics circulating via direct indirect consumption, ultimately impacting even higher-order predators. Here, we assess impacts Chlorophyll concentrations, algal community structure, copepod survivorship, fish behavior experimental trials, addition simulated top-predator success plastic-exposed fish. Our results indicate that detrimental growth survival. We also observed transmission small spheres copepods predators, highlighting concerning pathway microplastic within aquatic ecosystems, where consumed plastics means. Primary consumers, like copepods, face dual pressures top-down forcing, they preferred over sources, bottom-up resource depletion, supplies limited exposure. findings demonstrate system-wide occur when included chains underscore urgent need comprehensive strategies mitigate entry into ecosystems.
