Abstract

The study of technogenic pollution of soils with heavy metals (HM) is an essential task for ecology. The analysis of the content of HMs in the park's soils shows the degree of pollution and the sources of its occurrence. The study of the elemental composition of soils is an objective method for assessing the state of the ecosystem. To determine the current state of heavy metal contamination in forest soils, the concentrations of their total forms were analyzed. Heavy metals, including Zn, Pb, Cr, Cu, Hg, Cd, and As, were found in the study area. In addition, the threat of contamination with Cd and As has been identified. The calculation of the total pollution coefficient allows us to assess the level of pollution for the dry season (Zc = 18.45-28.24, average 22.45) as average (moderately hazardous) and for the wet season (Zc = 0.01-5.11, average 1.96) as permissible. This indicates an unfavorable environmental situation. The content of heavy metals in soils depends on the season. Observations show that at the end of the wet season, the concentration of heavy metals decreases, while it increases in the period after the dry season.

Abstract

Tropical ecosystems play an important role in the environment. Coastal areas are subjected to a wide range of impacts and pollution, which have drawn worldwide attention over the past few decades. Comprehensive studies of heavy metal content in soils worldwide are extremely important for assessing and predicting ecological risks. Very few studies have been devoted to a complete study of the physicochemical characteristics of soils, assessment of heavy metal accumulation in coastal zones along the Djibouti coast, and potential ecological risks. The study investigated the physico-chemical characteristics of soil, assessed the accumulation of heavy metals in coastal zones along the Djibouti coast, and analyzed the potential environmental risks associated with the presence of heavy metals in the studied soils. Analysis of heavy metals and trace elements in the soils of the coastal areas of Djibouti revealed that the levels of these elements are lower than in soils of the Red Sea coast and are in line with WHO and other international standards. All heavy metals in the soil of the studied area demonstrate low levels of potential ecological risk. The soils of the studied areas, overall, have not undergone significant heavy metal pollution and can be considered suitable for various types of use.

Abstract

Coastal regions are highly sought after for human habitation, exhibiting a population density that is threefold greater than the global mean. These zones are pivotal for environmental resources, human prosperity, and economic activities, providing a suite of services. The concept of ecosystem services has garnered international focus for its contribution to sustainable development. These services represent the myriad benefits that ecosystems confer, meeting socio-economic demands and enhancing human welfare. This analysis endeavors to appraise the value of ecosystem services in coastal areas, with a particular emphasis on the physicochemical properties of soils along Djibouti's coastline. It incorporates an assessment of local characteristics, climatic conditions, and the anthropogenic influence on the environment. Despite facing considerable threats to its biodiversity, Djibouti's coastline offers a plethora of vital ecosystem services to its inhabitants. Among the regulatory services rendered by these locales are air quality management, erosion mitigation, soil and sediment retention, climate and microclimate stabilization, carbon storage and sequestration, nutrient recycling, and facilitation of pollination.
