Today, effluents from municipal wastewater treatment plants are utilized as an alternative water source in some cities of US, Asia, Europe, and Africa. However, wastewater effluents are also recognized as a source of numerous chemicals such as pharmaceuticals, personal care products, antibiotics, and pesticides. In addition, the wastewater effluent matrix is assumed to be more chemically complicated than pure pharmaceutical mixtures since it contains not only anthropogenic micropollutants but also soluble microbial products (SMP), metabolites/transformation products produced during treatment processes, and natural organic matters (NOM) derived from tap water. This review first overviews the complexity of wastewater as a chemical mixture system, and then, introduce previous findings on the biological impacts of wastewater samples, particularly those revealed by the application of toxicogenomic tools to the environmental and mixture samples. Finally, recent challenges to characterize the major origin of effluent-derived toxicity were presented. This review highlights the importance of prioritizing the pollutants for efficient control and monitoring of water quality under the limited human and financial resources.

The Fishery Agency conducted the investigations and researches on the restoration of tropical sea grass beds, which serves as feeding sites for dugongs. from FY 2001 to FY 2008. as a part of its project aiming at the coexistence of dugongs and the fishery. In addition to the results of the project, such as seedling production and transplanting techniques, the existing knowledge and information on the sea grass beds were collected and complied in a booklet. The former part of the booklet " A review for the restoration of tropical sea grass beds" summarizes existing knowledge and information on 1) the component species, functions and roles. 2) habitats and environmental conditions. 3) the distribution area and standing stock and 4) dugongs' biology and the relationship with tropical sea grass beds, while the latter part explains 1) restoration techniques of sea grass beds using hand grass planting. 2) seedling production techniques using Thalassia hemprichii, 3) transplanting techniques of artificially produced Thalassia hemprichii and 4) monitoring of created or restored tropical sea grass beds.
