  • Phytoplankton and water samples were repeatedly collected in November 2015; February and May 2016 from 12 sampling sites in Truc Bach lake. 115 species and subspecies of phytoplankton had been recorded. They belong to 5 divisions (Cyanobacteriophyta, Bacillariophyta, Pyrrophyta, Euglenophyta, Chlorophyta). Cyanobacteriophyta hadthe largest density (23 species, 8021 cells/l). Based on Palmer index (Pollution index), Shannon - Weiner index (Diversity index)and physiochemical and biological parameters, we found that Truc Bach lake was polluted with organic substances, especially substances that are hard to decompose and nitrogenous sewage.

  • This study aims to assess the environmental condition of selected water bodies in Ngọc Thanh commune, Phuc Yen district, Vinh Phuc province. Water quality was assessed by using macro-invertebrates as bio-indicators. Field collection from 20 sampling sites in December 2015 has yielded 71 aquatic macro-invertebrates families, 64 of which were included in the BMWPVIET scoring system. Among 20 sampling sites, eleven sites (from site S10 to site S20) were classified at the α-Mesosaprobe level (quite polluted), with ASPT scores ranging from 3.0 to 4.9; two sites (S7 and S8) with ASPT scores 5.5 and 5.7 respectively, were classified at the β-Mesosaprobe (quite polluted); seven sites (from si...
