Purpose: The research is carried out to determine the concentration of heavy metals in surface water downstream Mekong River. Methods: sampling method follows Vietnamese national standard (TCVN 6663-6:2018, ISO 5667-6:2014). metal indicators analyzed using an atomic absorption spectroscopy machine. lowest detection level measurement approximately 0.2µg (on average for all measured). Results and discussion: Among 5 parameters studied December 2023, has not exceeded standards Vietnam (the...
Forests serve as vital ecosystems, playing a pivotal role in preserving biodiversity, maintaining air and water quality, regulating the climate, all while delivering many benefits to humanity serving critical resource for diverse industries. This study investigated changes forest cover within Yok Don National Park surrounding areas Dak Lak province, Vietnam, over period from 2001 2021. The primary objective was identify decadal shifts through utilization of freely accessible satellite remote...
ABSTRACT Unsustainable exploitation activities (UEAs), combined with the increasing impacts of global climate change are key causes that lead to soil erosion in North-Central Vietnam. Mountainous areas Vietnam commonly have steep slopes and sandy clay surface layer, which contribute enhancing erosion, resulting a serious loss life property. This study investigates land cover (LCC) across Thanh Chuong district by combining Remote Sensing Technique (RST) data Geographic Information System...
Rivers, such as the Dong Nai, Saigon, and Mekong, are subject to urban, industrial, agricultural pollution, leading a high risk of heavy metal accumulation in bottom sediments. With aid boat bucket tools, survey was conducted collect sediment samples from coastal areas (downstream Mekong Rivers) islands (Con Dao, Tho Chu) Southern region Vietnam during April May 2023. Out total 35 collected, preserved according guidelines Ministry Natural Resources Environment, indicators were analyzed by...
Purpose: This article presents the results of research on content some heavy metals in bottom sediments lower Mekong River (Vietnam). Methods: The sediment samples were collected using a Van Veen sampling bucket, model 3-1775-A10, provided by Wildlife Supply Company/Science First – USA. concentration elements (referred to here as 'HM parameters') was determined an atomic absorption spectrophotometer (Model: ZEEnit 700, Manufacturer: Analytik-Jena Germany), following instructional manual and...
ABSTRACT Globally, there is enough evidence to affirm that climate change one of the main factors causing changing trends in rainfall features (CTRFs). The aim this study, therefore, assess CTRFs across rice cultivation regions (RCRs) Plain Reeds Vietnam. Vietnam a prime example impacts (ICC) on agricultural activities. Daily data series from 16 observation stations during period 1984-2015 were appraised for quality and then detected by applying Mann_Kendall test Sen’s slope estimator. at...
