  • Overseas Environmental Measures of Japanese Companies(Vietnam )
    Chapter 1 Overview of Environmental Issues and Environmental Conservation Practices in Vietnam This chapter is divided into seven sections that provide basic information necessary for Japanese companies to implement effective environmental measures in Vietnam. Section 1 presents the outline of Vietnam and discusses its relations with Japan and Japanese companies, and Section 2 gives information about environmental problems in the country as they exist now. Section 3 explains the country's environmental policy, legislation, administrative structure, and other related matters. Sections 4 through 6 provide information about the scheme and content of the country's specific environmental regulations designed to deal with water pollution, air pollution, and industrial waste, which are the country's principal environmental challenges and at the same time the problems against which Japanese companies are required to take countermeasures. Finally, Section 7 describes the process of environmental impact assessment required to be performed prior to building industrial plants or other facilities. In addition, Appendix 1 in the references at the end of this report carries the whole text of the Law on Environmental Protection, which was put into effect in January 1994 and constitutes the basis for Vietnam's environmental policy. Appendices 2 through 4 contain excerpts of three pieces of environmental legislation that have a lot to do with Japanese companies doing business in Vietnam. 1 Section 1 Vietnam and Japanese Companies 3 Chapter 1 – Section 1 1. Increasingly Closer Japan-Vietnam Relations Centering in Economy The Socialist Republic of Vietnam (hereinafter called Vietnam), located in the eastern part of the Indochina, has a population of 77 million, the second largest in Southeast Asia after Indonesia.

  • Updated Molecular Phylogenetic Data for Opisthorchis Spp
    Dao et al. Parasites & Vectors (2017) 10:575 DOI 10.1186/s13071-017-2514-9 RESEARCH Open Access Updated molecular phylogenetic data for Opisthorchis spp. (Trematoda: Opisthorchioidea) from ducks in Vietnam Thanh Thi Ha Dao1,2,3, Thanh Thi Giang Nguyen1,2, Sarah Gabriël4, Khanh Linh Bui5, Pierre Dorny2,3* and Thanh Hoa Le6 Abstract Background: An opisthorchiid liver fluke was recently reported from ducks (Anas platyrhynchos) in Binh Dinh Province of Central Vietnam, and referred to as “Opisthorchis viverrini-like”. This species uses common cyprinoid fishes as second intermediate hosts as does Opisthorchis viverrini, with which it is sympatric in this province. In this study, we refer to the liver fluke from ducks as “Opisthorchis sp. BD2013”, and provide new sequence data from the mitochondrial (mt) genome and the nuclear ribosomal transcription unit. A phylogenetic analysis was conducted to clarify the basal taxonomic position of this species from ducks within the genus Opisthorchis (Digenea: Opisthorchiidae). Methods: Adults and eggs of liver flukes were collected from ducks, metacercariae from fishes (Puntius brevis, Rasbora aurotaenia, Esomus metallicus) and cercariae from snails (Bithynia funiculata) in different localities in Binh Dinh Province. From four developmental life stage samples (adults, eggs, metacercariae and cercariae), the complete cytochrome b (cob), nicotinamide dehydrogenase subunit 1 (nad1) and cytochrome c oxidase subunit 1 (cox1) genes, and near-complete 18S and partial 28S ribosomal DNA (rDNA) sequences were obtained by PCR-coupled sequencing. The alignments of nucleotide sequences of concatenated cob + nad1+cox1, and of concatenated 18S + 28S were separately subjected to phylogenetic analyses. Homologous sequences from other trematode species were included in each alignment.

Fish were collected with 3 randomized samplings per season at 6 stations using 6 sets of gillnets. A total of 45 fish species were found and most were in the Cyprinidae family. The catch by gillnets was dominated by Parambassis siamensis with an average CPUE for gillnets set at night of 807.77 g/100 m2/night. No differences were detected on CPUE between the seasonal surveys. However, the CPUEs were significantly different (P<0.05) between the stations. The Pak Narmkam station had a higher CPUE compared to the Pak Narmpung station (1,609.25±1,461.26 g/100 m2/night vs. 297.38±343.21 g/100 m2/night). The results of the study showed that the Nong Han Wetlands is a lentic lake and the fish abundance was found to be medium. There were a few small fish species that could adapt to living in the ecosystem. Keywords: fish species, fish composition, abundance, CPUE, Nong Han wetland 1.

In Mozambique, where only 50% of the people have access to safe drinking water, this hepatotoxin is not monitored, and consequently, the population may be exposed to MCs. The few studies done in Maputo and Gaza provinces indicated the occurrence of MC-LR, -YR, and -RR at a concentration ranging from 6.83 to 7.78 µg L 1, which are very high, around 7 times · − above than the maximum limit (1 µg L 1) recommended by WHO. The potential MCs-producing in · − the studied sites are mainly Microcystis species.

In this study Cyanobacteria species of Mogan Lake, Beytepe Pond and Delice River were taxonomically investigated. The cyanobacteria specimens have been collected by monthly intervals from Mogan Lake and Beytepe Pond between October 2010 and September 2011. For the Delice River the laboratory samples which were collected by montly intervals between July 2007-May 2008 have been evaluated.Totally 15 genus and 41 taxa were identified, 22 species from Mogan lake, 19 species from Beytepe pond and 13 species from Delice river respectively. During the study species like Planktolyngbya limnetica and Aphanocapsa incerta were frequently observed for all months in Mogan Lake, Chrococcus turgidus and Chrococcus minimus were abundant in Beytepe Pond while Kamptonema formosum was dominant in Delice River. As a result species diversity and density were generally rich in Mogan Lake during fall and summer season while very low in the Delice River during winter season. 1. Introduction Cyanobacteria (blue-green algae) are microscopic bacteria found in freshwater lakes, streams, soil and moistened rocks. Even though they are bacteria, cyanobacteria are too small to be seen by the naked eye, they can grow in colonies which are large enough to see. When algae grows too much it can form “blooms”, which can cause various problems.

A total of 35 types of fish and shellfish were consumed in the surveyed village. Some species of fish had a high protein content (19-20 g/100 g sample) and quality (e.g., lysine content = 1,750-1,870 mg/g sample and 93.8- 97.9 mg/g protein). Their protein qualities were endorsed by amino acid score (amino acid score 100).

A total of 264 fish (12 species) were collected through 4 times from Decem- ber 2013 to June 2015. All collected fish were transferred to our laboratory on ice and examined by the artificial digestion method. More than 7 species of ZT metacercariae, i.e., Haplorchis taichui, H. pumilio, H. yokogawai, Centrocestus spp., Stellantchasmus falcatus, Pygidiopsis cambodiensis, and Procerovum sp. were detected. Metacercariae of H. taichui were collected in 58 (42.3%) out of 137 fish (5 species), and their average density was 42.9 per fish infected. Metacercari- ae of H. pumilio were detected in 96 (49.0%) out of 196 fish (9 species), and their average density was 23.6 per fish in- fected.
