The diversity indices (d, H', J') of lichens have a less close linear relationship with the AQI_SO2 index as shown by the low correlation coefficient. This result shows that lichen biodiversity indices may have a nonlinear relationship with the AQI_SO2 index. These data are considered the scientific basis of research on using lichens as biological indicators of the air environment, specifically indicators of SO2 content in the air in some provinces/cities in Northern of Vietnam.

The studies involving water bugs (Hemiptera) biodiversity and ecology are very few and have mainly focused on taxonomy. We conducted research and evaluation of diversity indexes of water bugs (Hemiptera) in different landscapes including forest habitats, agricultural lands, ponds, streams from 16 sampling sites in Bac Kan, Lao Cai, Ninh Binh and Ha Tinh provinces. As a result, a total of 43 species of 23 genera of 10 families were recorded.

In Vietnam, recent findings have recorded 25 species of the genus Amorphophallus. Despite some initial results of the contents of Amorphophallus spp. In Vietnam, th ose r esults only record the presence of species in Vietnam territory. In order to pick species with high-glucomannan content, potential to develop in Vietnam, there must be deeper research on species composition, the distrubution in areas, also ecological conditions, developing potential of Amorphophallus spp to become the resources of tuber used for Amorphophallus spp flour manufacturing.

In this study, we developed and validated a simple, rapid, and effective analytical method for the determination of 15 PAHs in fine dust samples (PM1.0 and PM2.5) by using a combination of ultrasonic extraction, solidphase extraction (SPE) clean-up, and GCMS/MS quantification. The validated method was applied to analyze PAHs in PM1.0 and PM2.5 samples collected from some areas in Bac Ninh Province, northern Vietnam.
