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......

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. Fift......

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......
Application of GIS and remote sensing to build up a map of environmental geological suitability for residential buildings on Thi Vai river basin
Tập 3 Số 1 - Trang 1-11 - 2019
Geological environment zonation is to divide the areas into relatively homogeneous units based on their natural factors such as hydrology, topography, geology, disasters... to create geoenvironmental units which suit a specific type of exploitation for the purpose of research or regional management. This study presents a process of integrating GIS and remotely sensed data to develop a map of envir......

Optimizing Electro-Fenton process for removal of atrazine from aqueous solutions using Taguchi method
Tập 5 Số 2 - Trang 369-376 - 2021
The purpose of this study is centered on the removal of atrazine, one of the popular organochlorines in Vietnam, from an aqueous solution, using an electro Fenton process with iron and carbon plated steel electrodes at a batch electro reactor. This study had applied the Taguchi method, one of the most uncomplicated cases of design of experiments involving the minimum number of experiments to be pe......
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 ......
