“…The test results cannot be used directly to derive expected environmental concentrations. Concepts for transferring results obtained under laboratory exposure conditions to service-life conditions still need to be developed or refined [ 21 , 22 ]. This restriction applies especially to organic substances that can be transformed during service life or in water.…”

Construction products are in contact with water (e.g., rain, seepage water) during their service lifetime and may release potentially harmful compounds by leaching processes. Monitoring studies showed that compounds attributed to construction products are found in storm water and the receiving bodies of water and that the release of biocides in urban areas can be comparable to the input of pesticides from agricultural uses. Therefore, a prospective risk assessment of such products is necessary. Laboratory leaching tests have been developed by the Technical Committee CEN/TC 351 and are ready to use. One major task in the future will be the evaluation of the leaching test results, as concentrations found in laboratory experiments are not directly comparable to the field situations. Another task will be the selection of compounds to be considered for construction products, which are often a complex mixture and contain additives, pigments, stabilization agents, etc. The formulations of the products may serve as a starting point, but total content is a poor predictor for leachability, and analysis of the eluates is necessary. In some cases, non-targeted approaches might be required to identify compounds in the eluates. In the identification process, plausibility checks referring to available information should be included. Ecotoxicological tests are a complementary method to test eluates, and the combined effects of all compounds—including degradation products—are included. A bio test battery has been applied in a round robin test and was published in a guidance document. Published studies on the ecotoxicity of construction products show the tests’ suitability to distinguish between products with small and larger effects on the environment.

“…Neste contexto, a coordenação de projetoscom a gestão e o reuso de solos escavadospode mitigar os impactos ambientais negativos, diminuir as distâncias de transporte, reduzir os volumes de material depositado em aterros e a necessidade de recursos naturais provenientes de jazidas. (BHUIYAN et al, 2011;DELGADO et al, 2009;SUER et al, 2014).…”

“…Nove dos doze países/regiões-membros da União Europeia possuem legislação específica de solos contaminados (Tabela 2-3). Holanda, Alemanha, Bélgica, Itália e República Tcheca possuem políticas abrangentes com recomendações, diretrizes e critérios para o reuso de solos contaminados (Tabela 2-4), inclusive com valores-limites para casos específicos de reuso (com exceção da República Tcheca) e testes de lixiviação de contaminantes (apenas a Alemanha e a Holanda) (FRAYE & VISSER, 2006;SUER et al, 2014).…”

“…De forma geral, a legislação atenta para a qualidade ambiental para reuso do RCC, ressaltando-se a importância da determinação de concentrações aceitáveis de compostos que podem estar presentes nos materiais (SUER et al, 2014). O valor limite varia conforme as diferentes metas de proteção ambiental; por exemplo, na Holanda visa-se proteger 95% das espécies terrestres potencialmente afetadas, enquanto na Bélgica visa-se a proteção de 90% (SUER et al, 2014). O estabelecimento do valor limite também considera a avaliação do risco de exposição aos contaminantes para a saúde humana e preservação dos ecossistemas conforme o uso previsto da construção onde se dará o reuso.…”

“…O estabelecimento do valor limite também considera a avaliação do risco de exposição aos contaminantes para a saúde humana e preservação dos ecossistemas conforme o uso previsto da construção onde se dará o reuso. Na avaliação de risco, se for o caso, também pode ser considerado o reuso/reciclagem de materiais após demolição da construção (SUER et al, 2014;SUSSET & GRATHWOHL, 2011).  determinação dos métodos de escavação de materiais;…”
