This research is conducted to analyze and point out the relationship between environmental pollution and aquaculture development in the coastal areas in Vietnam. In this study, we use the binary Logit model (Y = 1/0) where the variable, Y, reflects the risks and losses in the household's aquaculture; and X is a vector of factors affecting the event. The results show that, among determinants, household's aquaculture experience (X1), the water pollution degree of the household (X4), intensive farming mode of the household (D1) influence household losses, while other variables such as educational attainment of the household head (X2) and farming area (X3) are not correlated with household losses. Based on the findings, some recommendations are given in the aspect that aquaculture households in the region to use new, more effective methods to protect the aquaculture environment in developing countries, including Vietnam.

There are huge amounts of emissions associated with construction industry during its different stages from cradle till building demolition. This study presents a methodology that integrates multi-objective optimization and multi-criteria decision making (MCDM) in order to enable construction decision-makers to select the most sustainable construction alternatives. Four objectives functions are investigated, which are: construction time, lifecycle cost, environmental impact and primary energy in order to construct the Pareto front. A novel hybrid MCDM is designed based on seven multi-criteria decision making techniques to select the best solution among the set of the Pareto optimal solutions. Sensitivity analysis is performed in order to determine the most sensitive attribute and construction stages that influence environmental emissions. The analysis illustrates that WSM, COPRAS and TOPSIS provided the best rankings of the alternatives, primary energy is the most sensitive attribute for different MCDM methods. Moreover, PROMETHEE II is the most robust MCDM method.

Plastic pollution is one of the most importation subjects of water contaminations in the world. Plastic pollutions not only threats locally, but also, they are widespread, posing broader risks to the world and environment. Plastics which act as pollutants are categorized by size into micro-, meso-, or macro debris. The micro plastics move through oceans from one region to another region. Today, there are several evidence of micro plastics in south pole where we believe it as a clean area. This paper surveys the effects of micro plastics on the Great Lakes.
