NEW SCIENTIFIC PUBLICATIONS FROM CARE IN 2025

The Centre Asiatique de Recherche sur l'Eau (CARE) is pleased to introduce four new research articles published in 2025. These studies reflect CARE's continued efforts to contribute to the fields of water quality assessment, groundwater modeling, environmental toxicology, and atmospheric monitoring.

1. Assessing Spatial Trends and Land Use Impacts on Surface Water Quality: A Case Study of the Saigon and Vam Co Rivers in Southern Vietnam

Authors: Thi-Minh-Tam Le, Truong-An Nguyen, Trung-Tin Nguyen, Tuyet T.N. Nguyen, Phuoc-Dan Nguyen, Julien Némery, Christine Baduel

Published in: Case Studies in Chemical and Environmental Engineering (2025)

Quartile: Q1

This study examines surface water quality across the Saigon and Vam Co river basins by integrating pollution indices, land use data, and spatial analysis. Results reveal high levels of heavy metals in downstream areas linked to urban and agricultural activities. The findings emphasize the influence of land use patterns on ecological risks and the need for targeted management strategies.

This study was funded by project ĐA2024-20-01 (VNU-HCM).

2. Revealing Vertical Distribution of Atmospheric Mercury Using Drone-Based Monitoring Technique: A Case Study in Vietnam

Authors: Duc Thanh Nguyen, Kiet Le Nguyen Tan, Hien Bich Vo, Pham Thi Dieu Huong, Nguyen Thi Thuy, Le Quoc Hau, Ly Sy Phu Nguyen

Published in: Atmosphere (2025)

Quartile: Q2

This study presents the first drone-based monitoring of total gaseous mercury (TGM) across different altitudes in an industrial zone of Southern Vietnam. UAV-mounted samplers were used to collect data at 50 m, 200 m, and 500 m. The research identified three distinct vertical distribution patterns of TGM under varying emission conditions, demonstrating the method's potential for high-resolution atmospheric monitoring.

This study was funded by project ĐA2024-20-01 (VNU-HCM).

3. Multigenerational Ecotoxicity of Tris(2-butoxyethyl) Phosphate to the Tropical Water Flea Ceriodaphnia cornuta and Probabilistic Ecological Risk Assessment in Freshwater Environments

Authors: Tan-Duc Nguyen, Van-Tai Nguyen, Khuong V. Dinh, Claudia Wiegand, Zhen Wang, Christine Baduel, Thanh Luu Pham, Thi Thuy Duong, Quoc-Hung Nguyen, Van Manh Do, Thi Phuong Quynh Le, Yu-Chen Huang, Thanh-Son Dao

Published in: Aquatic Toxicology (2025)

Quartile: Q1

This is the first multigenerational toxicity study of TBOEP on Ceriodaphnia cornuta, a tropical freshwater zooplankton. Delayed adverse effects were observed at environmentally relevant concentrations. The study also applied species sensitivity distributions to derive ecological thresholds, contributing to improved ecological risk assessment in tropical regions.

4. Multigenerational Testing Reveals Delayed Chronic Toxicity of Bisphenol A to Daphnia magna: A Common Characteristic of Endocrine-Disrupting Chemicals?

Authors: Tan-Duc Nguyen, Trong-Nhan Huynh, Van-Tai Nguyen, Khuong V. Dinh, Claudia Wiegand, Thanh Luu Pham, Manh-Ha Bui, Tomoaki Itayama, Ngoc Tuan Tran, Zhen Wang, Thanh-Son Dao

Published in: Environmental Pollution (2025)

Quartile: Q1

This research investigated the chronic effects of sublethal Bisphenol A (BPA) exposure on Daphnia magna across six generations. While early generations showed minor effects, the sixth generation exhibited reduced body size and fertility. The study highlights the potential for delayed multigenerational toxicity from endocrine-disrupting chemicals, reinforcing the need for long-term testing.
