Abstract
Data on the content of plant pigments in the bottom sediments (BSs) of the water bodies of Central and South Vietnam are given for the first time. The average concentration of chlorophyll a and phaeopigments (Chl + Ph) in total reaches up to 3.9 μg/g dry matter in rivers, 5.6 in ponds, 13.8 in sand quarries, 56.8 in reservoirs, and 245 in lakes. Most frequently, the concentrations of Chl + Ph in the coastal zones of watercourses and water bodies fall in the oligotrophic category, and those in the central areas are in the hypertrophic category. Relationships between concentrations of Chl + Ph and water depth, content of oxygen near the bottom, moisture content, volumetric mass, and concentrations of organic matter (OM) in the BSs are found. The content of sedimentary pigments in tropical waters of Vietnam is similar to that in freshwater ecosystems of temperate latitudes, despite the substantial differences of climatic zones in temperature and light regimes.
