Carbonized plant remains recovered from the ancient city Dascyleum (Daskyleion) in the province of Balıkesir in northwestern Turkey provide an outline of several phases of plant use in archaic, Hellenistic, and medieval times. At the study site, various crop plant remains of Near Eastern agriculture, including cereals (barley, Hordeum vulgare L. and bread/durum/rivet wheat, Triticum aestivum L. / T. durum Desf. / T. turgidum L.) and pulses [bitter vetch, Vicia ervilia (L.) Willd.; grass pea, Lathyrus sativus L. / L. cicera L.; fava bean, V. faba L.; and chickpea, Cicer arietinum L.] were found. Drupaceous fruits and pyrenes of buckthorn (Frangula alnus Mill.) were also found, probably representing dyes and/or medicines used by the inhabitants of the mound. Archaeometrical analyses of the ancient buckthorn pyrenes by high performance liquid chromatography with photodiode array detector (HPLC-PDA) provide chemical evidence for traces of ancient mordants remaining until the present day. Some of the pulse seed remains retrieved from the medieval layers at the study site were found to have been infested by bruchid beetles (Bruchidae).

Ground-level sulphur dioxide is one of the air pollutants of high concern as a typical indicator of urban air quality. To inform decisions regarding, for instance, the protection of public health from elevated SO₂ levels in the city of Balikesir, an understanding of spatial-temporal variance of SO₂ patterns is necessary. Therefore, the aim of this study is to locate sample points, characterize distribution patterns, perform the probability map, and map SO₂ distributions by means of spatial information sciences. In this work, the data were compiled from 48 sampling sites using passive sampling on 10-17 March 2010 (in winter) and on 13-20 August 2010 (in summer). The estimations of SO₂ levels at unsampled locations were carried out with the inverse distance weighted method. Finally, locations exceeding the Turkish Air Quality Standard threshold value were determined in the Balikesir by use of geostatistical algorithms (Indicator kriging). The capability of the methods to predict air quality data in an area with multiple land-use types and pollution sources were then discussed. The results of the passive sampling study show that the winter and summer average concentrations are 32.79 µg/m³ and 28.27 µg/m³ for SO₂, respectively. It is expected that where industrial activity is not excessively important, traffic and domestic heating systems are the main source of SO₂ precursors. Moreover, using Indicator Kriging, results show that there are multiple hotspots for SO₂ concentrations and they are strongly correlated to the locations of industrial plants, traffic, and domestic heating systems in Balikesir.
