This study also contributes to reducing environmental pollution caused by plastic and glass waste as well as current construction brick production methods. The results show that the bulk density, compressive strength, and bending strength of brick samples made from PET plastic and glass waste are higher than those of burnt clay brick samples, while water absorption is much smaller than that of burnt clay brick samples.

The aim of this is study to analyze and compare the amount of microplastics in the surface water and water column samples at Han River estuary (Da Nang) in the rainy season 2023. Sixteen water samples (eight water column samples and eight surface water samples) were collected and analyzed to determine the quantity, shape, color, size, and polymer forms of microplastics.

Water quality plays an immensely significant role in safeguarding the health of humans and other species on the planet. Polluted water sources can contain harmful substances such as heavy metals, pesticides, bacteria, and viruses, which can pose threats to human health and other organisms. Water quality is also a crucial factor in protecting the environment and sustaining the ecosystems of freshwater and marine environments. Polluted water sources can impact the lives of aquatic animals and plants, causing harm and endangering biodiversity by disrupting the food chain.

Microplastics are regarded as an emerging threat to water and other environments. The increasing use of plastics in agricultural cultivation has led to higher risks and more dangerous pollution of agricultural water. However, microplastics in agricultural water in Vietnam have neither been studied nor documented in any publication.

A Abatement: Reducing the degree or intensity of, or eliminating, pollution. Abatement Debris: Waste from remediation activities. Absorbed Dose: In exposure assessment, the amount of a substance that penetrates an exposed organism's absorption barriers (e.g.,, skin, lung tissue, gastrointestinal tract) through physical or biological processes. The term is synonymous with internal dose. Absorption Barrier: Any of the exchange sites of the body that permit uptake of various substances at different rates (e.g., skin, lung tissue, and gastrointestinal-tract wall).

The research herein builds on the work of Rojek (2003) and further investigates the bioremediation of NOM wastes. The aim of this research was to evaluate the effectiveness of selected white-rot fungi and yeast for the biodegradative removal of concentrated NOM from solution. The effectiveness of the white-rot fungus P. chrysosporium ATCC 34541 for the biological degradation of different batches of MIEXTM NOM concentrate and the effects of different characteristics of the NOM on the process and thus the resistance of the NOM to microbial removal were investigated.

The rapid economic growth in Vietnam has resulted in an increasing demand for electricity. This in turn translates to a higher rate of coal resource extraction and consequent rise in pollution of water and land resources. This study estimated the environmental costs associated with the electricity demand requirements of the coal electricity sector, as a component of the long-run marginal opportunity cost (LR-MOC) of electricity production.
