The aim of the present study was to evaluate the biochemical responses of the skeletal muscle and cardiac tissues of the urban pigeon as a bioindicator organism tested in diverse environments (Szpęgawa as a rural environment and Słupsk as an urban environment, Pomeranian Voivodeship, northern Poland), resulting in changes in the level of lipid peroxidation at the initial and final stages of this process and the activities of Krebs cycle enzymes (succinate dehydrogenase, pyruvate dehydrogenase, isocitrate dehydrogenase, and alfa-ketoglutarate dehydrogenase). Szpęgawa village was chosen due to the intensive use of the European motorway A1 with significant traffic and pollution levels. The concentration of Pb was higher in the soil and feathers of pigeons nesting in the polluted areas (Szpęgawa). Our studies have shown that the presence of lead in soil and feathers of the pigeons resulted in the activation of lipid peroxidation, destabilization and increased activity of lysosomal membranes, and activation of mitochondrial enzymes of the Krebs cycle with energy deficiency (reduction of ATP levels) in cardiac and skeletal muscle tissues simultaneously.

本研究的目的是评估城市鸽子骨骼肌和心脏组织的生化反应，作为在不同环境（Szpęgawa 作为农村环境和 Słupsk 作为城市环境，波美拉尼亚省，波兰北部）测试的生物指示生物，导致该过程初始和最后阶段的脂质过氧化水平以及三羧酸循环酶（琥珀酸脱氢酶、丙酮酸脱氢酶、异柠檬酸脱氢酶和α-酮戊二酸脱氢酶）的活性发生变化。选择 Szpęgawa 村是因为欧洲高速公路 A1 的密集使用，交通和污染水平很高。在污染地区 (Szpęgawa) 筑巢的鸽子的土壤和羽毛中铅的浓度较高。
