Incense burning is an important topic facing many countries in Asia. As a highly urbanized area, the overlapping of urban functional blocks in Hong Kong has resulted in many temples being located near residential and commercial areas. Therefore, the pollutants emitted by temples’ incense burning could cause severe health problems to the population. This study identified 366 Hong Kong temples and classified them into four categories: open, semi-closed, closed, and non-active, according to their incense burning characteristics. Among them, open temples have the largest average area and least quantity. Principal component analysis (PCA) indicated that building density, greenery density, water density, and temple weight are the most highly influencing factors. The temple weight is the only loading factor with a contributing factor from PC2, especially in 2006 and 2011. Furthermore, the linear regression model has been applied to analyze the correlation between variables. Although this study did not reach conclusive results about the actual impact of each temple type, the model results confirm that the temple is a sub-factor to respiratory mortality. This provides the theoretical foundation for government policy establishment of temple construction planning and community optimization in Asian cities.

Indoor air pollution caused by combustion is a common problem in low-and middle-income countries which negatively affects human health. In Asian countries, burning incense in temples, pagodas, or residences is popular. This study consists of three contents (i) monitoring air quality parameters, including total volatile organic compounds (TVOCs), particulate matter (i.e. PM10 and PM2.5), and CO2 concentration in five pagodas in Ho Chi Minh City and Binh Duong province; (ii) determining air pollutants concentration generated by incense burning in room; and (iii) investigating incense smoke removal ability of photocatalytic devices. The results showed that the average air pollutants concentration in the pagodas was 625-1,108 ppb of TVOCs, 1,935-2,967 ppm of CO2, 1,175-2,137 μg/m3 of PM2.5, and 1,589-2,871 μg/m3 of PM10 in which TVOCs, PM2.5, and PM10 were presented at the threshold of direct impact on human health. Burning seven types of incense in a room revealed that the cinnamon incense smoke contained the highest concentration of TVOCs. Using photocatalytic devices for incense smoke treatment showed that the photocatalyst provided the best removal efficiency of VOCs (48.13%) was zinc salt-impregnated titanium dioxide with Zn/Ti molar ratio of 0.5% and calcined at 500 oC. This result was initially successful in finding a way to low down VOCs concentration generated from incensation to allowable level (490 ppb).

Four terracotta busts of a woman with unique attributes were unearthed in Olbia during excavations of 1936 and 1959. The attributes include a cone-shaped bowl on the head, corymbs in the hair, a taenia on the forehead and floral décor. For a long time, scholars considered the woman a personification of goddess Demeter. At the beginning of the 21st century, the Danish scholar Pia Guldager Bilde was the first to change this attribution to Ariadne, Dionysus’ wife, based on five small fragments of similar busts found during N. O. Leipunskaia’s excavations in the sector of the «Lower town: North» (NGS) in Olbia. Following other scholars, she also identified them as thymiateria – utensils for incense burning in bowls. Despite the absence of other characteristic elements and traces of soot, they were named “Ariadne thymiateria”. Later, T. M. Shevchenko published seven more fragments of similar busts, which in her recent publications were identified as thymiateria depicting one of the participants of the Dionysiac thyasos: a nymph, Ariadne, Semela and others, or even young Dionysus himself. Such contradictory interpretations of the above terracottas led to their comprehensive analysis. The first of two planned articles on this topic develops a typology of this group of terracotta busts, which distinguishes between three iconographic types. The first and the third type include one item each. The second iconographic type is the most numerous and has two variants. Variant A comprises eleven items from Olbia excavations from different years, including four fully restored terracotta busts with the abovementioned iconographic attributes. The hypothetical subvariant Aa is the head of a similar bust from the excavations of Scythian Neapolis. Variant B comprises one fragment from Chersonesos Taurica. We have reasons to believe that terracottas of all three iconographic types were created in the 3rd century BC. This assumption is supported by the chronology of closed contexts, in which around half of them were discovered, including terracotta busts that are generally dated back to the 3rd century BC. Most likely, these busts were last used for rituals in family sanctuaries in the middle of the 2nd century BC. We assume that the shape of the bowl on the head of terracotta woman busts was made by Olbian artists under the influence of local ceramic thymiateria in the form of a cone-shaped tall-stem bowl from the 3rd century BC. Taking into account the absence of any traces of soot in the bowls on the busts and their practical use of thymiateria, we believe that these original terracotta items were used for votive purposes. The pouring of essential oil into the coarse, widely open bowl is questionable considering the very high price of the aromas, discovery locations in blocks where artisans and middle-income merchants were living, the terracotta texture, and lack of proper coating and lids with holes. The shape and the size of the bowl, a white engobe on its inner sides, and the floral décor on the woman’s head let us assume that it could be used for putting inside small fruit or seeds. According to this use, these busts were used as votives, pseudo-thymiateria or a kind of aroma bowls for dry flowers or fragrant plants.
