Necessity of normalization to aluminum to assess the contamination by heavy metals and arsenic in sediments near Haiphong Harbor, Vietnam

2012 | Elsevier

While assessing many different aspects of contamination by heavy metals and arsenic in sediments, the natural variability in element contents which depends on the grain-size and mineralogical composition of sediments, needs to be taken into account. In previous studies, the normalization of element contents to a reference element such as Al was commonly applied to compensate for granulometric and mineralogical effects. In the present study, through the investigation on the contamination of heavy metals and arsenic in sediments near Haiphong Harbor, the necessity of the normalization towards Al is assessed.

Technical Guidelines for Plastic and Resin Pellet Leakage Prevention from Formal and Informal Recycling Factories, Hanoi - Vietnam

2024 | RRC.AP, AIT, ASIAN INSTITUTE OF TECHNOLOGY

These guidelines aim to provide a framework for preventing recycling-related plastic and pellet losses, and environmental leakage. The guidelines are useful for a broad spectrum of stakeholders, particularly policymakers and key plastic recycling actors, including informal waste pickers, junkshops, consolidators, and plastic recycling craft villages. The application of these guidelines is expected to contribute to improving production efficiency in the plastic recycling chain while preventing plastic leakage into the environment.
