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...
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...

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 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.

Developing IDF curve of extreme rainfall at Tan Son Hoa station for the period 1980-2015
Tập 1 Số M2 - Trang 73-81 - 2017
Recently, the Intensity – Duration – Frequency (IDF) relationship of extreme
rainfalls in a local area is usually investigated to provide accurate required
data for calculating, planning, and developing urban drainage systems,
especially in the context of climate change. Traditionally, IDF curves are
computed based on a statistical method for analyzing the frequency of occurrence
or non-occurrence...
Study on the use of sludge farming of catfish as organic fertilizer and evaluate its effectiveness in agriculture
Tập 4 Số 1 - Trang 128-139 - 2020
The purpose of this study is to reuse fishpond sediment to produce organic
fertilizer for planting maize. The sludge was mixed with rice husk and Composted
under aerobic conditions. The effectiveness of Compost on planting maizes was
assessed by adding to maizes with and without combination chemical fertilizers
as different dosages as recommendations. The amounts of Compost adding for
maizes were ...

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...
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...
