“…Despite the considerable decline in anthropogenic lead emission, in some regions, for example, in the vicinity of non‐ferrous metal works, its amount in the air is high enough to warrant actions that aim at limiting its emission to zero. Given that any amount of lead is toxic and it tends to accumulate in living organisms, the issue of the impact that lead has on people, even in small doses absorbed while breathing, remains open 22 …”

In this work, we developed and used research methods that will make it possible to quickly assess the toxic activity of, among others, metal nanoparticles. In this work, we assessed the toxicity of PbO nanoparticles obtained from biological synthesis using Farfarae folium. The obtained PbO nanoparticles were characterized with the use of such methods as UV-VIS, XRD, SEM with EDS, AFM and FTIR. The techniques applied in the work confirmed the presence of 30-40 nm PbO nanoparticles.The toxic properties of biologically synthesized nanoparticles were assessed with the use of plants and invertebrates. The phytotoxicity studies were conducted on the following plant seeds: radish, garden cress, bean, rape, chia, lupine, corn, and beetroot. The IC50 coefficient was calculated on the basis of the logarithmic relationship A w = a*ln(C) + b. The studies also used the following invertebrates: Daphnia pulex, Tubifex tubifex, Chaoborus sp. (larva), Chironomus aprilinus, Artemia sp. The EC50 coefficient was calculated after the incubation period. For PbO nanoparticles, we managed to identify the IC50 coefficient for selected plants. It was, respectively, 0.150 mg/ml for lupine; 0.274 mg/ml for bean; and 0.655 mg/ml for radish.As regards the studies on invertebrates, it was observed that the most sensitive organisms were Daphnia pulex (EC50 = 0.32 mg/ml) and Tubifex tubifex (EC50 = 0.38 mg/ml), and the most resistant one was Chironomus aprilinus (EC50 = 0.83 mg/ml).

Find of a Bronze Macehead from the Kraków-Częstochowa Upland in Poland

The Upper Silesian Museum in Bytom houses an interesting find of a macehead discovered in the Michałowiec nature reserve (commonly known as the Michałowiec/Michałówka Forest). The reserve is located on the northern slope of a large rise of terrain of the Kraków-Częstochowa Upland (Polish: Jura Krakowsko-Częstochowska) that shelves toward the River Biała Przemsza valley. Regrettably, the exact coordinates of the find location are not known, and only very imprecisely defined forest limits where the discovery was made were indicated. The artefact in question is a reasonably well-preserved macehead of the so-called star-shaped type. The macehead was cast in a pre-prepared mould using a non-ferrous metal alloy with a dominant share of Cu, Pb, and Sb. A comparative analysis of maceheads with finds from the territory of Hungary and south-eastern Europe, as well as a concentration of such finds along the southern and the eastern borders of Poland allow for a supposition that such artefacts could also come from this direction. On the other hand, it cannot be excluded that the find is of local manufacture. Concerning its chronology, on the basis of analogies a wide time frame between the 12th and the first half of the 14th century can be proposed. The territory of the Kraków-Częstochowa Upland is a landscape that since the early 14th century has been marked by numerous works of military architecture. These were the background of the defensive system of the border of the Kingdom of Poland. Therefore, a high number of warriors could be at least temporarily stationed in this area. This can perhaps offer grounds to rather accept a later (that is, the 14th century) chronology of the artefact. Such a date can also be implied by its chemical composition.
