TÍTULO:
RESPONSE OF SOIL ATTRIBUTES AN IRREGULAR SOLID WASTE URBAN DISPOSAL
PALAVRAS-CHAVES:
Dumping ground. Environmental indicators. Soil degradation.
Inappropriate disposition of urban solid waste causes physical and chemical processes responsible for soil degradation, such as compaction, erosion, and the increment of heavy metals and salts concentration. Being part of an open and dynamic system, degraded soil affects other components of the river basin, such as surface and subsurface water bodies, the atmosphere, vegetation and the fauna. And even years after the end of the unsuitable disposal, degradation processes may persist if measures to recover these areas are not implemented. Therefore, it is fundamental to understand how the soil response to this waste disposal is influenced by the environmental factors. This understanding helps to make decisions regarding the management of these areas, as well as filling a gap in the literature that tends to generalize models of coverage systems without taking into account regional characteristics and soil genesis factors. Thus, the objective of this work is to evaluate the response of the soil attributes of different deactivated areas of irregular waste disposal. The hypothesis is that the soil attributes response, after the deactivation of the area, is influenced by environmental factors. This study will evaluate 13 deactivated solid waste disposal areas, located in municipalities of different regions of Rio Grande do Norte, selected with the aim of studying different soil classes. Will be anilyzed the following attributes: soil density, particle density, total porosity and grain size; pH, electrical conductivity, organic matter content, available phosphorus and total nitrogen; (Mn, Pb, Zn, Cd, Cu, Mo, Co, Cr, Ba and Ni). In addition, the loss of soil by erosion will be estimated, and from this, the loss of nutrients and contaminants. The Principal Component Analysis will be done in order to gain a broader understanding of how different soil types respond to inadequate solid waste disposal.
