This study aimed to assess the antimicrobial and antioxidant activities of 61 marine fungal strains isolated from 34 samples collected in the research journey of the Akademik Oparin vessel in the North Sea of Vietnam in 2021. Of these, 23 were from sponges, 21 from seaweeds, 15 from sediments, and only 2 from seawater.

In this study, eukaryotic microbial communities associated with coral Acropora formosa and its natural surroundings, sediment and seawater, in a coral reef ecosystem of Whale Island, Nha Trang Bay, Vietnam were investigated. First, genetic material was taken from Acropora formosa’s surface mucus layer (SML) as well as the sediment underneath and seawater above the colonies from four different sampling locations in a coral reef ecosystem.

Sampling frequency plays important role in water quality monitoring activity. A suitable sampling frequency could save time and cost of monitoring work. In this study, coastal seawater quality of the Northeast of Quang Ninh Province, Vietnam was evaluated by single indicator and statistical analysis of the monitored data from 2016–2019.

Currently, Cr(III) and Cr(VI) are analyzed directly in trace level using anion-exchange liquid chromatography inductively coupled plasma mass spectrometry (LC – ICP – MS), which is wellknown as an expensive and complicated method. Therefore, determination of Cr(VI) and Cr(III) by spectrometer or combine with ICP (or AAS) is seemly prefer to choose in almost laboratories although this method presents a higher limit of detection (LOD) and is influenced by salt ions in seawater.

Samples of Granulated blast furnace slag (GBFS) from Formosa steel plant (called as Formosa GBFS) were collected and used for several testing series regarding potential application as an alternative material in construction and civil works. Unhydrated GBFS particle shows river sand-like shapes by all appearances with more angular and therefore, it shows higher shear strength than those of natural sand.

In this study, the effects of salt solutions with different seawater proportions on some geotechnical properties of soft soil distributed in some areas from Mong Cai to Thanh Hoa province have been extensively investigated. The undisturbed soil samples were soaked into different salt solutions for ten days before testing.

In parallel with these results, the diagrams of Gibbs et al. supported the same seawater intrusion phenomena. Brackish karst springs first roseand then fell below sea level with epirogenic movements during the geological period, and therefore, karstification progressed. The samples were oversaturated with calcite, dolomite, and quartz, whereas they were undersaturated with gypsum and halite. The Al, Cu, and Zn values of some of the water samples exceeded the tolerance limit of aquatic life standards.

The metal complexes are retained on resin at pH 6.0 and eluted with 1.0 mol L −1 HCl in acetone in both methods. After the optimum conditions were determined, the methods were applied to seawater, stream water, rice, lentil, tea, tobacco, bulgur, chickpea, wheat, red pepper, black pepper, peppermint, and dried eggplant samples in order to determine the levels of copper and cadmium.

The results also showed that Ha Thanh and Rach Lo sites recorded the highest contents of most studied metals in oyster samples. Levels of metals in oyster were in the order of Zn > Cu > As > Pb > Cr > Cd > Hg and the contents of metals in oyster did not reflect a correlation with those in surrounding environment.

Analysis of samples which were taken at Yangshan port in China in 2011, 2012 to assess the level of heavy metal pollution of heavy metals and petroleum hydrocarbon with two main purposes; the first is to evaluate the main pollutants and their pollution level; the second is to evaluate the impact of operations on the port to environmental quality. The application of Grey clustering model to assess heavy metals and petroleum hydrocarbons shows that the heavy metals and petroleum hydrocarbons in sea water at Yangshan Port was at grade I.

In this study, we (1) isolated V. parahaemolyticus from seawater samples collected in some regions in the north of Vietnam, (2) evaluated and selected the virulent strain, and (3) created an inactivated vaccine using a selected strain and finally tested the relative percentage survival (RPS) of the inactivated vaccine on tilapia (Oreochromis niloticus). Our study aims to develop an effective and commercially-potential vaccine to prevent damage of V. parahaemolyticus on fish farming, especially on species with high economic value.

The study is also expected to explore the most intrinsic value of Pteroplinthite Mangrove Forests that can be integrated as a landscape design element. These intrinsic values of this mangrove forest are being manipulated to be integrated into the urban landscape design setting. The data collection involved the observation, site inventory, determination of physicochemical contents of seawater, and collected sample plants and soil that is conducted in two selected areas, namely Pasir Panjang, Port Dickson and Kuala Linggi, Melaka.

Research on the profile of Fe in the seagrass ecosystem has been carried out. Analysis of seawater, sediment, seagrass samples from the association of mangroves, mangroves-coral reefs and coral reefs taken in the waters of Donggala Regency was carried out using the ICP-OES method (Inductively Coupled Plasma-Opticaly Emission Spectrometry).

The origin and chemistry of the groundwater in the middle Pleistocene (qp2 3 ), lower Pleistocene (qp1 ), upper Pliocene (n2 2 ), lower Pliocene (n2 1 ), and the Miocene (n1 3 ) in the Mekong river delta (MKRD) were investigated by using isotopic and geochemical techniques. The origin of the groundwater was evaluated based on the composition of the water stable isotopes (d2 H and d18O) in the local precipitation, in water from the rivers system, and in the groundwater samples.

A Radium Delayed Coincidence Counter (RaDeCC) includes 3 channels ( 223Ra channel, 224Ra channel, and total channel). It has been newly designed and assembled at Nuclear Research Institute. To determine 223Ra and 224Ra in seawater samples, the system efficiency at all 3 channels were investigated and calibrated.

İzmir Bay has been one of most polluted bays of the Mediterranean for a long time. When the “Big Channel Project” was completed in 2000, sewage flow into the bay ended. Hence, the influence of creeks, which are the only source of water transportation to the inner bay, was investigated in the current study. Monthly samples of creek water and seawater were taken.

The aim of the present study was to investigate biosurfactant-producing culturable bacteria inhabiting the coast of the Arabian Sea at Karachi. Overall, 15 seawater samples were collected from the Arabian Sea coast of Karachi. Isolation, characterization and screening for 89 biosurfactant-producing bacterial strains were conducted through 8 conventional screening tests.
