Abstract. Plastic is an emerging pollutant, and the quantities in rivers oceans are expected to increase. Rivers assumed transport land-based plastic into ocean, fluvial marine processes have been relatively well studied date. However, controlling tidal estuaries, interface between systems, remain largely unresolved. For this reason, current estimates of riverine pollution export ocean highly uncertain. Hydrodynamics estuaries influenced by tides freshwater discharge. As a consequence, flow...
Abstract Water hyacinth is an aquatic free-floating plant that highly invasive, to the extent it now present in most freshwater bodies sub-tropical and tropical regions worldwide. Due ecological socio-economic damages these plants can cause, monitoring their spatial coverage seasonality key for development of timely efficient mitigation measures. Hyacinth patches are sufficiently large be detectable high-resolution satellite imagery, allowing using freely available remote sensing data...
Marine litter is a significant threat to the marine environment, human health, and economy. In this study, beach surveys along Vietnamese coasts were conducted in local context quantify characterize using modified GESAMP monitoring guideline. A total of 21,754 items weighing 136,820.2 g was recorded across 14 from September 2020 January 2021. Plastic most abundant type by both quantity (20,744 items) weight (100,371.2 g). Fishing gear 1 (fishing plastic rope, net pieces, fishing lures lines,...
Riverine litters can negatively impact human livelihood and aquatic life especially macroplastics, which could injure animal plant species, harm to hydraulic systems vessels, increase urban flooding due clogging. There are many studies on floating macroplastics in this river, Saigon river is recognized as one of the most polluted rivers Vietnam globally date; however, riverbank macroplastic pollution still lacking so far. In study, surveys were carried out downstream nearby Thu Thiem 1...
Rivers represent one of the main conduits for delivery plastics to sea, while also functioning as reservoirs plastic retention. In tropical regions, rivers are exposed both high levels pollution and invasion water hyacinths. This aquatic plant forms dense patches at river surface that drift due winds currents. Recent work suggests hyacinths play a crucial role in influencing transport, by efficiently trapping majority within their patches. However, comprehensive understanding interaction...
River plastic pollution is an environmental challenge of growing concern. However, there are still many unknowns related to the principal drivers river transport. Floating aquatic vegetation, such as water hyacinths, have been found aggregate and carry large amounts debris in tropical systems. Monitoring entrapment plastics hyacinths therefore crucial answer relevant scientific societal questions. Long-term monitoring efforts yet be designed implemented at scale various field measuring...
Abstract Marine debris is a significant threat to the marine environment, human health and economy in Can Gio island, Vietnam. In this study, we conducted beach litter surveys quantify characterize from six transects region for first time using OSPAR monitoring guideline. A total of 29,456 items weighting 529,432 g was recorded 12 two campaigns December 2019 (dry season) June 2020 (rainy season). Plastic most abundant type terms quantity (a 26,662 items) weight (325,606 g), followed by paper...

This study is the first to comprehensively investigate potential of circular economy (CE) principles enhance sustainability mushroom production, focusing on resource efficiency and waste reduction. A systematic literature review conducted in 2024 assessed global state CE applications cultivation, emphasizing eight commonly cultivated species Vietnam: Lentinula edodes, Ganoderma lucidum, Trametes versicolor, Hericium erinaceus, Cordyceps militaris, Auricularia heimuer, Pleurotus ostreatus,...
<p>Water hyacinths appear to play an important role in gathering and transporting macroplastic litter riverine ecosystems. These fast-growing free-floating invasive freshwater plants tend form large patches at the water surface, which makes it possible detect map them freely available imagery collected by European Space Agency (ESA) satellites. In polluted rivers, hyacinth may thus serve as a viable proxy for macroplastics. However, ~10m spatial resolution offered Sentinel-1...
Abstract For an ecotoxicological screening of recently deposited sediments, samples were collected from Ho Chi Minh City’s canals in August 2015. The sediments characterized by physico-chemical analysis metals, PAHs, PCBs, and other organic micropollutants, standard sediment toxicity testing. results showed that the both urban suburban areas contained a mixture contaminants with concentrations several PCBs OCs being above thresholds for effects to benthic organisms. chemical analyses...
<p>Water hyacinths are considered one the world’s most invasive aquatic species and found in tropical rivers. Hyacinths can form dense patches of several meters length width at water surface drift due to combined action wind flow velocity. In rivers, hyacinth function as carriers for floating macroplastic debris from rivers into ocean. Saigon river, Vietnam, were accumulate a majority total items (Schreyers et al., 2021). Despite their crucial role accumulation...
This paper investigates the implementation of household low-power energy harvesting (LoPEH) wireless sensor networks (WSN) over log-normal fading channels. The relays are battery-operated and stochastic harvested flow to batteries is characterized with Markov property buffer status. communication established combination direct link cooperative relays. best relay chosen based on a selection (RS) scheme namely optimal (OPRS). It can be drawn that within particular range signal-to-noise ratio...
<p>Our recent field-based study undertaken at the Saigon river, Vietnam, shows that water hyacinths are responsible for entraining and transporting a majority of floating macroplastic litter. These invasive, free-floating plants can form patches several meters in length width tend to aggregate large amounts plastic Over course six-week study, we demonstrated 78% observed were carried downstream accumulated within these plant patches.</p><p>The strong...
