“…The color of both samples is dark grey, the Bromo sample is a little lighter, which supports the interpretation of a higher amount of SiO 2 and/or colorless silicates and oxides. In literature, often the exact acid digestion parameters for volcanic ash analysis are not given (e.g., [10,12], and in some cases they are similar to ours [13]. Thus we conclude that the concentrations reported do not include the insoluble fraction, or it is calculated as different SiO 2 up to 100% (Wahyuni, 2016).…”

The volcanic eruptions of Mt. Bromo and Mt. Raung in East Java, Indonesia, in 2015 perturbed volcanic materials and affected surface-layer air quality at surrounding locations. During the episodes, the volcanic ash from the eruptions influenced visibility, traffic accidents, flight schedules, and human health. In this research, the volcanic ash particles were collected and characterized by relying on the detail of physical observation. We performed an assessment of the volcanic ash elements to characterize the volcanic ash using two different methods which are aqua regia extracts followed by MP-AES and XRF laboratory test of bulk samples. The analysis results showed that the volcanic ash was mixed of many materials, such as Al,

“…This active biomonitoring technique has been often used to evaluate distribution of pollutants released by human activities in industrial and/or urban areas Tretiach et al, 2007). The same technique has been successfully applied also in volcanic environments (Arndt et al, 2014;Calabrese et al 2014). Many biomonitoring studies were carried out on Mount Etna, due to the suitable condition for sampling and monitoring the dispersion of volcanogenic species (Notcutt and Davies, 1989;Martin et al, 2009Martin et al, , 2012Quayle et al, 2010).…”

Volcanic emissions were studied at Mount Etna (Italy) by using moss-bags technique. Mosses were exposed around the volcano at different distances from the active vents to evaluate the impact of volcanic emissions in the atmosphere. Morphology and mineralogy of volcanic particulate intercepted by mosses were investigated using scanning electron microscopy (SEM) equipped with energy dispersive spectrometer (EDS). Particles emitted during passive degassing activity from the two active vents, Bocca Nuova and North East Crater (BNC and NEC), were identified as silicates, sulfates and halide compounds. In addition to volcanic particles, we found evidences also of geogenic, anthropogenic and marine spray input. The study has shown the robustness of this active biomonitoring technique to collect particles, very useful in active volcanic areas characterized by continuous degassing and often not easily accessible to apply conventional sampling techniques.

“…Heavy metals are natural elements found throughout the environment. Some scientists are of view that they form naturally in the Earth's core and emerge to the surface through hydrothermal vents (Minic et al, 2006) or volcanic eruptions (Calabrese et al, 2015). While this is likely the case, human activity results insubstantial quantities of heavy metal waste from power plants and manufacturing industries, such as mining activities, oil refinery or urban wastewater treatment plants.…”

Heavy metals such as arsenic, cadmium, mercury and lead constitute a serious threat to human health. Generally, regular consumption of fish is recommended because it is a good source of omega-3 fatty acids, which have been associated with health benefits. However, flesh of some fish species contains heavy metals in high concentration, which may pose health risk for individuals that consume them in significant quantities. Therefore, over the last few years, evaluation of heavy metals in fish has become a matter of great global concern and especially in Kingdom of Saudi Arabia.The aim of the present work was toassess the concentration of the most toxic heavy metals present in fish caught along the eastern and western coasts of Saudi Arabia, which was achieved through several studies. Results yielded by analyzing 73 fish species and 1,027 edible fish part samples from 12 sampling sitesrevealed considerable variation in metal concentrations across the sampling locations and fish species. Amounts of some of heavy metals were below the maximum allowed limit. Moreover, high hazard index (HI > 10) was obtained for the consumption of some fish species caught at specific sites, which indicates a high probability of consuming populations experiencing adverse health effects.
