Integrated assessment of the natural conditions on suitability and adaptation of the project of conversion of dipterocarpaceae forest into rubber plantation in Dak Lak province
Tạp chí Khoa học Trái Đất và Môi trường Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 2 Số 2 - Trang 38-49 - 2019
Sy Chi Phung, Tu Cong Trinh
The results of surveys, investigation and assessment show that the climate conditions of dipterocarpaceae forests are relatively suitable for the growth and development of rubber trees. However, there are some rather severe indicators such as seasonal rainfall distribution, low humidity, inundation in rainy season and drought in the dry season; High and low temperatures reach the limit for the req...... hiện toàn bộ
Evaluating the application ability of membrane-less microbial fuel cells in shrimp farming wastewater recirculation

A separation of plastic debris in Saigon river sediment using a microplastic sediment separator
Tạp chí Khoa học Trái Đất và Môi trường Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 5 Số SI1 - Trang SI137-SI146 - 2021
Bao-Son Trinh, Vu Nguyen Dam, Bich Luyen Thi Pham, Huy Cam Pham
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 ...... hiện toàn bộ
PM2.5 personal exposure and sources of population living near 2 environment monitoring stations in Ho Chi Minh city
Tạp chí Khoa học Trái Đất và Môi trường Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 1 Số M1 - Trang 26-34 - 2017
Canh Thanh Truong, Dan Xuan Vu
Air pollution epidemiology studies have found statistically significant associations between particulate matter (PM) concentrations and morbidity, mortality. 24-h personal PM 2,5 exposures were sampled by PEM 2,5 (SKC) with flowrate 4 l/minute on teflon filter (Pall). 64 households in Binh Thanh and district 2 (HCM city) were monitored from 7/2007 to 3/2008, repeated 9 times for each household.
