Natural and thermally modified Pine, Ash, and Acacia woods were exposed in two different en- vironments: urban and maritime/industrial. The weathering effects were evaluated during 24 months regarding color, chemical, and structural changes. In all wood species, thermal modifi- cation induced color, chemical, and structural changes. All woods became darker (Pine ΔL*: 32.01; Ash ΔL*: 36.83; Acacia ΔL*: 27.50), t...

A madeira é um material biodegradável e isso constitui um fator limitante para a sua aplicação no exterior, caso não haja uma proteção adequada. Neste sentido, o tratamento térmico é um dos métodos utilizados para aumentar a durabilidade da madeira. Uma das vantagens deste processo é que não requer qualquer tipo de adição de químicos. A temperatura utilizada no processo induz a alterações químicas dos constitui...

Toxicity of Sodium Molybdate and Sodium Dichromate to Daphnia magna Straus Eval...

Diamantino, Teresa C.; Guilhermino, Lucia; Almeida, Elisabete; Soares, Amadeu M. V. M.

As a result of a widespread application in numerous industrial processes, chromium is a contaminant of many environmental systems. Chromium and their compounds are toxic to both invertebrates and vertebrates and, for this reason, there has been a search for suitable and less toxic alternatives. Molybdenum compounds have been studied as alternative to chromium compounds for some industrial applications. The toxi...
