In aquatic environments, assessment of microplastic concentrations is increasing worldwide but environments from developing countries remain under-evaluated. Due to disparities facilities, financial resources and human between countries, protocols sampling, analysis observations used in developed cannot be fully adapted ones, required specific adaptations. Viet Nam, an methodology was commonly adopted by local researchers implement a monitoring sediments surface waters 21 (rivers, lakes,...
Mangroves are areas that connect the land and sea, important to ecosystem. They places for food sources habitat of aquatic fauna in tidal areas. However, existence plastic debris poses a risk environment. This study aimed investigate accumulation microplastics (MPs) sediment cores from two mangrove The first area is outer section Songkhla lagoon (SK), while second coastal Pattani province (PN). Sediment core sampling was performed SK = 8 stations PN 5 stations. Surface enrichment MP...
Microplastics (MP) are omnipresent in ecosystems. Some studies focus on MP fates and their toxicology biota for the last ten years world. In present study, was identified bivalve (Perna Viridis) collected Vietnam first time using micro-Fourier transform infrared Microspectroscopy (µFTIR) technique. Organisms were digested by KOH 10% solution then separated KI 50% solution. The average concentration evaluated at 2.60 MP/individual 0.29 MP/gram of wet tissue. Six types found with a high...
A large amount of plastic waste has been released into the environment during increase in global production 21st century. Microplastics (0.1 µm to 5 mm size) existing hydro-systems, especially aquatic sediments, can enter organisms and then human body through food chain. This paper provided preliminary observation results on microplastic presence surface sediment aquaculture ponds (fish) Hanoi city 2021. Our showed that concentrations ranged from 2,767 ± 240 2,833 176 items.kg−1 dry weights...
In order to examine the degree of human‐induced alteration nitrogen and phosphorus cycles at scale a tropical watershed regional dimension, budgets these two elements were estimated in four main sub‐basins (Da, Lo, Thao, Delta) Red River system (156 448 km 2 , Vietnam China). The differ widely population density (from 101 inhabitants −2 upstream basins more than 1000 delta), land use, agricultural practices. terms production, on one hand, consumption food feed other, are autotrophic systems,...
Abstract Phosphorus (P) plays a strategic role in agricultural production as well the occurrence of freshwater and marine eutrophication episodes throughout world. Moreover, scarcity uneven distribution minable P resources is raising concerns about sustainability long‐term exploitation. In this paper we analyze cycle anthropic systems with an original multiscale approach (world region, country, large basin scales) two contrasting world regions representative different trajectories...
Silver nanoparticle (AgNP) has a wide range antibacterial effect and is extensively used in different aspects of medicine, food storage, household products, disinfectants, biomonitoring environmental remediation etc. In the present study, we examined growth inhibition engineered silver nanoparticles against bloom forming cyanobacterial M. aeruginosa strain. AgNPs were synthesized by chemical reduction method at room temperature UV–Vis spectroscopy, scanning electron microscopy (SEM),...
In this study, biochar was derived from the agricultural by-products coconut coir (BC1) and rice husk (BC2) activated with NaOH 25%. This material characterized through analytical methods such as SEM images, XRD, FTIR, Raman. Analysis results indicated that carbon structure is amorphous many graphene layers. A high specific surface area detected 364.22 m 2 .g -1 for BC1 329.71 BC2 meso micropores when analyzed by N CO adsorption. The also showed anionic cationic dye adsorption capacity...
The Red River Delta (RRD) (Vietnam), a region experiencing rapid population growth, industrialization, and economic development, concentrates 54% of the whole watershed in less than 10% basin area. Our study aimed at understanding quantifying processes by which delta affects nutrient fluxes coming from upstream before they reach sea. A comprehensive budget nitrogen (N), phosphorus (P), silica (Si) associated with natural anthropogenic terrestrial hydrological system was established for five...
Microplastics are widespread in coastal and marine environments, sediments serve as a sink for microplastics. In this study, four sediment cores were collected from the Kuala Gula Mangrove area. The abundance of microplastics mangrove ranged 25–130 items/kg dry weight. highest microplastic was observed at KG04 site near mouth river. number by sampling significantly different (p < 0.01), with station having fiber content. dominant color blue, main shape fiber.
