The study aimed to examine the accumulation pattern and concentrations of heavy metals and minerals in different tissues of dogs (hair, kidney, brain, liver). Additionally, it explored the feasibility of utilizing these samples for identifying potential environmental impacts associated with these pollutants. ICP-MS was used to analyse the samples for concentrations of heavy metals. The obtained values were assessed
considering various factors that could impact the levels of minerals and metals in the organisms of animals, including age, gender, and habitat.
Generally, heavy metals recorded higher levels in the hair, liver and kidneys of dogs living outdoors compared to the ones living indoors. Of all types of samples lead had the highest levels in female dogs, in dogs younger than 5 years and in those living outdoors. The results also show that hair, among all samples, plays a significant role for the evaluation
of heavy metals pollution.
