Tạp chí Khoa học Trái Đất và Môi trường Đại học Quốc gia Thành phố Hồ Chí Minh - Tập 1 Số M2 - Trang 47-56 - 2017
Hung Pham, Trung Van Le, Phu Le Vo
The Da Dang river basin, located in the Upper Part of Dong Nai River, plays a crucial role to protect water resources in the downstream parts. The purpose of this study is to assess and develop a soil erosion map in the Da Dang river basin by using the Revised Universal Soil Loss Equation (RUSLE) combined with remote sensing (RS) and Geographic Information System (GIS). The factors used in the RUS...... hiện toàn bộ
Typical pathogens on plastic debris in downstream of Sai Gon and Dong Nai rivers: an initial observation

Plastic pollution is recently receiving significant attention. In aquatic ecosystem, plastic debris can provide a habitat for microbial communities, including pathogens which might cause ad-verse impacts on aquatic animals and human health. This study, for the first time, investigated densities of typical pathogens of Coliforms and Vibrio spp. associated on plastic samples col-lected in surface wa...... hiện toàn bộ

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
Presence of Arsenic anomalies in groudwater and its related with geological structures: case study of Dak Nong province

Arsenic is the most carcinogenic element and its anomalies in groundwater in different regions of the world are the result of natural sources and/or due to human activity. High levels of arsenic in drinking water can lead to negative impacts on human health and ecosystems. In Dak Nong province, a number of Arsenic anomalies have been detected that are higher than the allowable value according to Q...... hiện toàn bộ
