A estratégia de remediação in situ, que recorre à adição de corretivos orgânicos, ou inorgânicos, permite a reabilitação destes solos, melhorando as suas características e imobilizando os contaminantes, colocando-os em formas menos biodisponíveis. Os corretivos adicionados ao solo podem ser, preferencialmente, resíduos, cuja valorização vai ao encontro das metas Europeias estabelecidas relativamente à deposição de resíduos em aterros. De facto, é fundamental a diminuição dessas quantidades, valorizando os resíduos, e promovendo a sua integração no sistema produtivo. Este estudo teve como objetivo avaliar o uso sustentável de materiais provenientes da indústria da pasta de papel e do papel (cinzas de biomassa e lamas biológicas) na melhoria da qualidade de solos contaminados por atividades mineiras na Faixa Piritosa Ibérica (FPI): Minas de Aljustrel, Lousal e São Domingos), em dois tempos distintos: 1 e 25 meses após a aplicação dos materiais. Foram utilizados parâmetros físico-químicos e ecotoxicológicos. Os resultados sugerem que os aditivos testados permitiram uma clara melhoria nas propriedades físico-químicas dos solos, essenciais para a recuperação das suas características e funções, e diminuição nas respostas tóxicas para vários organismos-teste, Pseudokirchneriella subcapitata, Thamnocephalus platyurus e Daphnia magna, quando expostos a extratos dos solos corrigidos.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract In the remediation of soils potentially contaminated by mining activities, it is important to consider environmentally sustainable technologies, applicable to large areas. The in situ remediation strategy that consists in the addition of organic, or inorganic, amendments, allows the rehabilitation of these soils, improving soil characteristics and immobilizing contaminants, turning them into less bioavailable forms. The recovery of this type of materials meets the European goals established for the disposal of waste in landfills, considering that it is essential to reduce the quantities deposited in landfills and increase their recovery, promoting their integration into the production system. This study aimed to evaluate the sustainable use of materials from the pulp and paper industry (biomass ashes and biological sludge) in improving the quality of soils contaminated by mining activities in the Iberian Pyrite Belt (IPB: Aljustrel, Lousal and São Domingos Mines), at two different times: 1 and 25 months after application of the materials. Physicochemical and ecotoxicological parameters were used in that evaluation. The results suggested that the tested amendments allowed a clear improvement in the physicochemical properties of the soils, essential for the recovery of their characteristics and functions, and a reduction of the toxic response of several test organisms, Pseudokirchneriella subcapitata, Thamnocephalus platyurus and Daphnia magna, when exposed to the soil-water extracts of amended soils.]]></p></abstract>
