Application of groundwater quality index (GWQI) and principle component analysis (PCA) to assess the groundwater quality of Pleistocene aquifer in Tan Thanh district, Ba Ria – Vung Tau province
Tập 2 Số 2 - Trang 107-115 - 2019
This research applied the groundwater quality index (GWQI) and principal
component analysis (PCA) for assessing pollution levels and factors effecting
groundwater quality of Pleistocene aquifer in Tan Thanh district, Ba Ria – Vung
Tau province. Seventeen wells were colected in April (dry season) and October
(rainy season) during 5 years (2012-2017). Nine parameters of water (pH, TDS, độ
cứng, Cl-,...
Air emission inventory and application TAPM-AERMOD models to study air quality from 34 ports in Ho Chi Minh City
Tập 2 Số 2 - Trang 97-106 - 2019
The port system of Ho Chi Minh City including 34 ports, serves as the gateway to
the South (including the South East and the Mekong Delta) in export and import
activities. In which contribute a huge amount of pollutants to the atmosphere in
Ho Chi Minh City. The objective of this study is to: (i) Calculating air
emissions from ports system in Ho Chi Minh city using the SPDGIZ model which
emits a l...
Evaluate of air pollution dispersion and propose planing scenerios to reduce air pollution for livestock activities in Tan Thanh district, Ba Ria – Vung Tau province
Tập 2 Số 2 - Trang 26-37 - 2019
Livestock is one of the main activities of the agricultural sector in Tan Thanh
district, Ba Ria – Vung Tau province. Beside of pollution sources such as waste
water, solid waste, livestock activity in Tan Thanh district, Ba Ria - Vung Tau
province in recent years has caused air pollution in the livestock area and
surrounding area. This research was carried out to evaluate the process of air
pollu...
A separation of plastic debris in Saigon river sediment using a microplastic sediment separator
Tập 5 Số SI1 - Trang SI137-SI146 - 2021
Plastic debris was separated from Saigon river sediment using a microplastic
sediment separator (MPSS) for the first time. A separation fluid of ZnCl2
solution (1.6 kg/L) was used to separate lower density materials (floating on
the top) from higher density materials (sinking in the bottom). Plastic and
plastic-like materials were collected and analyzed by a FTIR spectrometer to
determine plastic ...
Application of material flow analysis (MFA) for estimating the potential of Nitrogen recirculation in closed-ecosystem based catfish farming
Tập 5 Số SI1 - Trang SI1-SI12 - 2021
The purpose of this study is to evaluate and analyze the possibility of nitrogen
recirculation when applying a closed eco-system for intensive catfish ponds in
the Mekong Delta in accordance with the existing available natural conditions in
the local area. A closed ecosystem is proposed for optimizing N emissions from
intensive pangasius farming on the basis of closed flows of materials, waste,
an...

Application of multivariate statistical analysis in the assessment of groundwater quality of Tan Thanh district, Ba Ria – Vung Tau province
Tập 1 Số M2 - Trang 66-72 - 2017
In the present study, Multivariate Statistical Analysis (MSA) such as Principle
Component Analysis (PCA) and Cluster Analysis (CA) were applied to determine the
temporal and spatial variations of groundwater quality in Tan Thanh district, Ba
Ria – Vung Tau province. Groundwater samples were collected from 18 monitoring
wells in April (dry season) and October (wet season) during the year 2012.

Agricultural residues biomass potential and applying efficiency for household scale biochar production in Go Cong Tay, Tien Giang province
Tập 1 Số M1 - Trang 68-78 - 2017
The paper presents results of rice straw biomass potential and applying
efficiency for household scale biochar production in Tien Giang, a typical case
study in Go Cong Tay district. The study results showed that the total rice
production of Go Cong Tay district was 185.072 tons/year and the rice straw
biomass corresponding 233.190,72 tons/year. This rice straw biomass have the
high organic ingred...
Analysis of riverbank changes in Ho Chi Minh city in the period 1989 – 2015
Tập 2 Số 2 - Trang 80-88 - 2019
The objective of this study was to analyze the changes of riverbanks in Ho Chi
Minh City for the period 1989-2015 using remote sensing and GIS. Combination of
Modified Normalized Difference Water Index (MNDWI) and thresholding method was
used to extract the river bank based on the multi-temporal Landsat satellite
images, including 12 Landsat 4-5 (TM) images and 2 Landsat 8 images in the
period 198...
An A2O-MBR system for simultaneous nitrogen and phosphorus removal from brewery wastewater
Tập 3 Số 1 - Trang 12-22 - 2019
Anaerobic/Anoxic/Oxic – Membrane BioReactor (A2O-MBR) system was used to enhance
simultaneous removal of nitrogen and phosphorus from brewery wastewater. The A2O
unit containing microorganisms with short solids retention time (SRT) was
employed mainly for removal of organic matter and phosphorus together with
denitrification. The MBR containing microorganisms with long SRT was employed
mainly for ...

The Triassic suture between Indochina and Sibumasu blocks - the first discovery of a backarc basin within Vietnam teritory
Tập 1 Số M2 - Trang 14-22 - 2017
A backarc basin represented by a mafic/ultramafic magmatic ophiolitic sequence
has been discovered first time within Vietnam territory. Backarc basin/forearc
basin and other features of a convergent tectonic system are being considered as
a location of the two geological blocks that almagamated together and preferred
as a geological suture. The middle Triassic suture resulted from the welding of
t...
