Agricultural soil samples were collected from the areas where edible plants had been cultivated in southern Poland. The PHE content decreased in proportion to the median value specified in brackets (mg/kg d.m.) as follows: Zn (192) > Pb (47.1) > Cr (19.6) > Cu (18.8) > Ni (9.91) > As (5.73) > Co (4.63) > Sb (0.85) > Tl (0.04) > Cd (0.03) > Hg (0.001) > Se (< LOQ). No PHE concentrations exceeded the permissible levels defined in the Polish law. The PHE solubility (extracted with CaCl₂) in the total concentration ranged in the following order: Fe (3.3%) > Cd (2.50%) > Ni (0.75%) > Zn (0.48%) > Cu (0.19%) > Pb (0.10%) > Cr (0.03%). The soil contamination indices revealed moderate contamination with Zn, ranging from uncontaminated to moderately contaminated with Pb, and, practically, no contamination with other PHEs was identified. The ecological risk indices revealed that soils ranged from uncontaminated to slightly contaminated with Zn, Pb, As, Cu, and Ni. The PCA indicated natural sources of origin of Co, Cu, Hg, Sb, Zn, Cr, and Pb, as well as anthropogenic sources of origin of Cd, Ni, As, and Tl. The human health risk assessment (HHRA) for adults and children decreased in the following order of exposure pathways: ingestion > dermal contact > inhalation of soil particles. The total carcinogenic risk values for both adults and children were at the acceptable level under residential (1.62E−05 and 6.39E−05) and recreational scenario (5.41E−06 and 2.46E−05), respectively, as well as for adults in agricultural scenario (1.45E−05). The total non-carcinogenic risk values for both adults and children under residential scenario (1.63E−01 and 4.55E−01, respectively), under recreational scenario (2.88E−01 and 6.69E−01, respectively) and for adults (1.03E−01) under agricultural scenario indicated that adverse health effects were not likely to be observed. Investigated soils were fully suitable for edible plant cultivation.

The influence of environmental pollution on the heavy metal content in oolong teas from the Fujian Province, China, and the health risk for the Polish consumers were studied. Average contents of the metals in made oolong tea leaves were (mg kg⁻¹): Al 1452, Cd 0.08, Co 0.23, Cr 1.59, Cu 10.5, Fe 140, Hg 0.10, Mn 1465, Mo 0.63, Ni 3.45, Pb 1.99, Sb 0.78, Se 5.15, Sn 3.16, Tl 0.28, and Zn 26.9. The metals easily released from leaves to infusions were: Tl, Se, Cd, Sn, Sb, Ni, Al, and Pb. No concentration of As, Hg, Mo, or Pb was found in the first infusion and no As, Co, Hg, or Mo was found in the second one. The hazard quotient values for particular metals found in the infusions and tea leaves and the appraised combined hazard index (HI) amounted to <1. The highest HI values, resulting from the consumption of both infusions, did not exceed 5.88E-03, or 6.94E-04a in the case of tea leaves. No health hazard for the Polish consumers of oolong teas was identified at any of the examined stages of consumption. However, we recommend discarding the first tea infusion to reduce the metal concentrations before consumption.

Surface samples (0–25 cm each) of agricultural soils were investigated in five Regions (voivodeships) of southern Poland. The mean Potentially Harmful Element (PHE) pseudototal content ranges were as follows (mg/kg): As 5.19–10.9, Cd 0.34–1.56, Co 1.92–6.70, Cr 9.05–25.7, Cu 8.74–69.4, Hg 0.001–0.08, Ni 3.93–19.9, Pb 20.3–183, Sb 0.80–1.42, Tl 0.04–0.17, and Zn 61.3–422. The PHE availability depended on pH, the organic carbon (C_org) content, and the pseudototal PHE content in soils. Exchangeable and acid soluble PHE contents (BCR_F1) determined in the Community Bureau of Reference (BCR) three-step sequential extraction procedure decreased in this order: Cd > Zn > Co > Ni = Sb > Cu > Tl > As > Cr = Pb. Actually available PHE contents in pore water (0.01 mol/dm³ CaCl₂) ranged as follows: Cd 0.81–17%, Cr 0–0.25%, Cu 0.01–2.31%, Ni 0.16–2%, Pb 0.2–0.49%, and Zn 0.25–2.12%. The potential soluble total content of PHEs in pore water (0.05 mol/dm³ Na₂EDTA) ranged as follows: Cd 27–91%, Cr 0.7–7.1%, Cu 6.7–98%, Ni 3.6–41%, Pb 15–41%, and Zn 3–34%. The mobility factor (MF) values indicated Cd (31.6%) and Zn (21.0%) as the most mobile elements in soil. Other PHEs followed the order of Co > Ni > Tl > As > Sb > Cu > Cr > Pb, with the MF values Pb > Sb > Zn > Co > Cu > Ni > Tl > As > Cr, and the same as described by the global contamination factor (GCF) values: Opolskie > Podkarpackie > Świętokrzyskie > Śląskie > Małopolskie.

Animal products are one of the main constituents of the human diet. They are the main source of energy, proteins, microelements, and bioactive substances. The most popular negative health impacts linked with the consumption of animal products are obesity, atherosclerosis, heart attacks, and cancer. Apart from human health, consuming animal products is also controversial lately, due to farm animals’ well-being and environmental protection issues. Thus, within the context of sustainability, the consumption trends of animal products were investigated through our on-line questionnaire surveys. The following animal products were involved in the survey: unprocessed meat (pork, beef, lamb, veal, mutton, chicken, duck, goose, turkey), processed meat (cold-cuts, sausages, pates), fish products, and eggs. Our research concluded that consumption among respondents with higher education was unsustainable for both unprocessed and processed meat, as eating habits in terms of type and quantity of consumed meat indicated respondents’ unawareness. The consumption of fish products was also revealed as unsustainable regarding the quantity of fish consumed in terms of its beneficial nutritional values. Egg consumption was revealed as the most sustainable among the investigated animal products. However, insignificant egg consumption among the respondents showed the actual need of social education in terms of the current knowledge regarding the beneficial aspects of eggs.

This study examines the critical interplay between migration, climate change, energy transitions, and socioeconomic disparities, highlighting their collective influence on regional resilience and sustainable development. By analyzing the existing literature, the study investigates how migration patterns are shaped by environmental stressors, energy challenges, and economic inequalities, emphasizing the dual role of migration as both a response to and a driver of climate change. Additionally, it explores the complex relationship between energy systems and migration flows, focusing on the impact of energy access, transitions, and sustainability efforts on socioeconomic conditions, particularly in vulnerable regions. The review identifies key gaps in the literature, especially regarding the economic and social implications of these interconnected factors. It also assesses how energy transitions can either mitigate or exacerbate regional disparities and resilience to climate-induced migration. This holistic perspective aims to inform future policy and research on climate migration, energy security, and socioeconomic equity.

Vegetables constitute a major component of human food security. They are the main sources of essential nutrients including antioxidants, natural dyes, minerals, and vitamins. Eating habit issues related to the consumption of vegetables are gaining importance within the context of a healthy lifestyle, longevity, and physical fitness. Additionally, food quality is of primary importance, and so-called eco-food (defined as food as natural as possible, without fertilizers, pesticides, or preservatives) seems to be the most popular world-trend in healthy nutrition. Keeping these ideas in focus, research on vegetable consumption in Poland in the context of conventional or organic production was performed using online questionnaire surveys. The results revealed that the rate of vegetable consumption depended primarily on economic status, except for the potato, which was a staple cutting across all economic strata. Among the 108 analyzed respondents, 74% bought vegetables from certified organic farms. However, 59% bought organic vegetables “rarely” or “sometimes”, and only 15% “often”. Next, respondents chose to buy vegetables from fresh food markets (45%) and in local shops (41%). About 20% of the respondents acquired vegetables from their own farms. Among the reasons for choosing vegetables from certified organic farms, respondents mentioned in decreasing order: “desire for proper nutrition” (30%), “thinking that organic vegetables are healthier” (28%), and “organic vegetables are generally better” (7%).
