It is well known that the construction sector is constantly growing, bringing a negative impact on the environment. Therefore, the purpose of this study is to assess the impact of construction materials on the content of Carbon and Nitrogen in soil. These two chemical elements, especially the Carbon:Nitrogen (C:N) ratio, are extremely important in organic matter and are among the most important in terms of soil structure, especially because they could provide information leading to characterization of the soil. Carbon in soil plays an essential role as food source for soil micro-organisms and as bacteria metabolite, while Nitrogen is an important nutrient for crop production. In this study, the C:N ratio was calculated in the case of soil samples taken from an area in full development, in Bucharest, where demolition of buildings took place recently. This ratio was compared with the one determined in the soil samples from the immediate surroundings, where vegetation grows. The obtained results indicated that the C:N ratio was lower in the case of soil samples taken from an area in full development compared with the one determined in the soil samples from the immediate surroundings, which indicates that construction materials influence the Carbon and Nitrogen content of the soil.
