Heavy metal pollution is a worldwide major concern. It represents a threat to humans, animals, plant health, and has negative impact on the environment. The Biolog Ecoplate approach was used to observe the daily changes in soil functional microbiome, in 5 sites from Baia mare exposed to historical pollution and after one year of bioremediation. The study has shown that EcoPlates are an effective tool for the assessment of microbial activity in heavy metal contaminated soils in Baia Mare. Microbial activity and diversity decreased with the degree of pollution, highlighting the impact of contamination on the soil microbiome. Within the analysed functional guilds, the values extracted showed a high range of activities. Polymers guild showed the highest activity in CT site, with a similar trend of carbohydrates and the maximum form of activities. Site FR induced the highest activity for carboxylic & acetic acids and amino acids, while the AWCD recorded its maximum.
