“…Implementation of the k 0 ‐method of NAA in many laboratories around the world has resulted in a preponderance of k 0 ‐NAA‐related publications on the implementation, application and refinement of the k 0 ‐standardisation method (e.g., Fadzil et al . , Menezes and Jaćimović ). This trend is not expected to change in the near future.…”

Advances in the chemical and isotopic characterisation of geological and environmental materials can often be ascribed to technological improvements in analytical hardware. Equally, the creation of novel methods of data acquisition and interpretation, including access to better reference materials, can also be crucial components enabling important breakthroughs. This biennial review highlights key advances in either instrumentation or data acquisition and treatment, which have appeared since January 2010. This review is based on the assessments by scientists prominent in each of the given analytical fields; it is not intended as an exhaustive summary, but rather provides insight from experts of the most significant advances and trends in their given field of expertise. In contrast to earlier reviews, this presentation has been formulated into a unified work, providing a single source covering a broad spectrum of geoanalytical techniques. Additionally, some themes that were not previously emphasised, in particular thermal ionisation mass spectrometry, accelerator‐based methods and vibrational spectroscopy, are also presented in detail.

“…For 9 to 64 days, all of the samples already shown to be wearing out due to the lesser particles that being leached out. Furthermore, the amount of liquid present is limited thus the elements particles has limited space for them to leached out competitively (Fadzil et al, 2010).…”

“…For future reference, the possible approximation of heavy metal content leached could be predicted by projecting the cumulative released value. In this study, the projection values are set to be up to 100 days and 100 years (Fadzil et al, 2010). The aim of this projection is to predict the leaching content released from the asphalt pavement that used PG76 binder.…”

“…Leaching test often used to simulate a submerging solid in water for a certain period of time (Chai et al, 2009) and the result can be used to estimate the amount leached. The leachate then analyzed by using latest equipment and tools such as Atomic Absorption Spectroscopy (AAS) and Inductively Coupled Plasma Mass Spectrometry (ICP-MS) (Hiller at al., 1999;Fadzil et al, 2010).…”

“…This study was done with the objectives to determine the physical characteristics of PG76 with the modification of Rediset addition to gauge the physical abilities through the tests of penetration, softening point, and ductility tests for the modified samples of asphalt binder PG76. Tank leaching test was conducted to simulate heavy rainfall and flash flood of the road as the sample submerged in acidic solution (pH: 4) for a set period of time (0.25, 1, 2.25, 4, 9, 16, 32, and 64) (NEN 7347, 2006: Fadzil et al, 2010 and projected to observe long term effect. The leachate then analyzed by ICP-MS instrument and then, the cumulative results of the heavy metals; Cd, Cu, Zn, Ni, Pb, Cr, Al, and Co would be tabulated and compared with Department of Environmental guidelines to determine its toxicity.…”

Asphalt binder, as one of pavement component is exposed to heat and rainfall. Polymer modified asphalt binder is a good alternative to withstand the weather in tropical countries. By utilizing warm mix asphalt additive, the high compacting and mixing temperature can be reduced. However, the impact to the environment and its characteristic towards high temperature need to be evaluated before putting it to use. In the study, the physical properties, thermal characteristics, and leaching and toxicity of PG76 incorporated with Rediset LQ were investigated. The Tank Leaching Test was carried out to mimic the worst scenario of flood event effect on the asphalt binder. The results of physical tests denote that the new material has relative consistency while the thermal analysis indicates that the materials are stable beyond their mixing and compaction temperature. The decomposition starts at temperature > 360°C and ends at temperature <500°C for all samples. The tank leaching test also found that the materials are safe to be used as pavement material because the heavy metal elements from the leachate are below the maximum allowable volume by the World Health Organization and the United States Environmental Protection Agency.
