This study was conducted to determine the soil contamination and accumulation of arsenic (As) heavy metals including chromium (Cr), copper (Cu), zinc (Zn), cadmium (Cd), lead (Pb) in 15 native cultivated plant species a Pb recycling area Dong Mai village, Hung Yen Province, Vietnam. The analysis 32 samples collected from seven different sites revealed that contents Al, Fe, As, Cr, Cu, Zn, Cd, soils ranged 6200–32,600, 11,300–55,500, 5.4–26.8, 24.9–290, 66.0–252, 143–455, 0.71–1.67,...
The essential oils from leaves and twigs of Magnolia hookeri var. longirostrata D.X.Li & R.Z.Zhou insignis Wall., growing wild in Ha Giang Province Vietnam, were obtained by hydrodistillation analyzed gas chromatography-flame ionization detector (GC-FID) chromatography-mass spectrometry (GC-MS). respective yields the M. leaf twig 0.14% 0.05% (v/w), 0.16% calculated on a dry weight basis. Major components were: Linalool (21.3%), (E)-nerolidol (12.2%) neo-intermedeol (13.5%) (leaf oil);...
The study investigates the decomposition of Chlorpyrifos Ethyl (CE) in tea-growing soils using Biomix under varied conditions, aiming to enhance safety agricultural products. 1 demonstrated a significant capability for degrading CE, particularly at higher temperatures and an optimal pH 6. It showcased microbial density lignindecomposing organisms 4.68×10 5 CFU/g cellulose decomposition, 3.6×10 hemicellulose, 2.5×10 lignin, indicating robust biodegradation potential. An intriguing outcome was...
Pesticides containing organophosphate (OP) compounds in general and Chlorpyrifos (CPF) particular are used to control insects pests. However, they have been proven be highly toxic not only some wild animals but also negative impacts on the environment human health. This study provides an assessment of effectiveness using microbial product (MP) degrade CPF a large- small-scale tea cultivation environment. The research results show that farming areas, residual exists both soil agricultural...
Bioremediation is a biological process to remove or neutralize environmental pollutants. This study was carried out investing at the efficacy of arsenic resistant endophytic bacteria isolated from Pteris vittata, Pityrogramma calomelanos, Blenchum orientale, and Nephrolepis exaltata, which grow in highly (As) contamination mining site Vietnam. Their segmented roots, stems, leaves were homogenized separately inoculated on LB agar plates containing 5mM As(III) As(V). A total 31 strains...
Essential oils from roots, flowers, fruits, and leaves plus stems of Angelica sinensis cultivated in Vietnam were obtained by hydrodistillation analyzed using GC/MS-FID. In total, 36, 30, 33, 27 compounds found accounting for 98.7%, 98.8%, 99.2%, 100% the compositions, respectively. (Z)-Ligustilide (49.4%, 29.6%, 25.8%, 28.9%) γ-terpinene (20.6%, 38.5%, 35.5%, 44.2%) main components respective essential oils. Especially, dictyopterene C (10.8%) was to be one fruit oil. Among A. oil samples...
This paper presents the study on effects of water holding bio-product lipomycin M mesofauna groups at Melinh station for Biodiversity. The results show that 25 belonging to 6 classes (Chilopoda, Diplopoda, Insecta, Arachnida, Crusstacea and Oligochaeta) were recorded there. number are different according vegetation covering soil. average density ranges between 28 125 individual/m2. has positive soil humidity, which makes advantageous condition grow develop. Therefore, it contributes improve...
From the field survey research between 2012 and 2021, we herein provide a list of 39 threatened species amphibians reptiles from Son La Province. Of these, following have high conservation values: two are listed in Governmental Decree No. 64/2019/ND-CP, 12 84/2021/ND-CP, CITES Appendices, 22 Vietnam Red Data Book (2007), 24 IUCN List (2022). In addition, 21 being exploited for food wildlife trade by local people. Major threats to habitat populations study areas include deforestation,...
The excess use of pesticides in the agricultural sector has caused environmental pollution and affected complete ecosystem. Among various commonly used pesticides, chlorpyrifos (CPF) is widely against multiple agrarian pests due to its effectiveness higher insecticidal activities. However, along with beneficial usage, CPF residual effects on environment, causing negative impacts aquatic organisms human health. Consequently, methods for eliminating background are essential. currently...
