A investigação do conteúdo orgânico em ecossistemas aquáticos, com ênfase na sua relação com a configuração do espaço físico e a forma de ocupação humana, constitui-se em uma importante ferramenta para auxiliar na gestão dos recursos hídricos. O objetivo desse estudo foi conhecer a inter-relação entre o conteúdo orgânico das águas superficiais e dos sedimentos de leito da rede natural de drenagem de microbacias da região do Cariri cearense. A partir dos resultados verificou-se a predominância da humina no conteúdo orgânico dos sedimentos. Foram obtidas correlações positivas entre os sólidos suspensos totais da água e as frações lábeis da matéria orgânica do sedimento (SST/CL e SST/CSA) e entre o potencial redox (do sedimento) e o CL. Correlação negativa foi obtida entre o oxigênio dissolvido da água e o CL. A ACP indicou que a alteração no conteúdo orgânico da água e dos sedimentos de leito estava associada ao processo de antropização das microbacias e ao lançamento de esgotos domésticos na rede natural de drenagem. Palavras-chave: Conteúdo orgânico. Águas superficiais. Sedimento de leito.

Mangroves are areas of permanent preservation, but anthropogenic interference in this ecosystem (for example the launching of pollutants from industrial, mining, fertilizer by farmers, sewage) is increasing startlingly. Preserve and look for ways to bioremediate mangroves is fundamental, since these maintain the productivity of coastal ecosystems and is thus regarded as a natural nursery. The need to study the mangroves has been growing in recent years, particularly in respect to the environmental characteristics of this ecosystem. This chapter aimed to draw a parallel between the damage that can be caused by the trace elements nickel and iron on the mangrove ecosystem, more specifically affecting the nutrition of mangrove plants, in addition to showing possible effects of the interaction of these metals with humic substances of organic matter acting on the mitigation of stresses caused to the ecosystem under study. Through surveys of the information covered in this chapter, it can be observed that the presence of trace elements such as Iron and Nickel at high levels can cause eminent stress to the plant structure within the scope of its sedimentary physiology and biochemistry. It is necessary to subsidize further studies so that it is explicit and approved by the scientific community that, this environment, which is sensitive and important, the basis for various trophic levels, needs greater attention from government officials for its preservation, as well as the restoration of those many mangroves that are polluted by being close to urban places, receiving an exacerbated supply of pollutants.
