Proposta de modelo cinético da degradação de laminados de madeiras em ambientes aquático e terrestre

Abstract: Kinetics aspects of wood sheets decay on aquatic and terrestrial environmentsA kinetic model for wood decomposition is proposed based on experimental data on the decomposition of wood from 12 species.The model takes into account the different decay coeficients for labile and recalcitrant compounds, in both terrestrial and aquatic ecosystems. It was verifed that: 1. the oxidation process of recalcitrant fractions are the main pathway for mineralization, because the leaching and/ or mineralization of the labile … Show more

“…Considering the cleaning of the accumulation basin, the need to safeguard specific areas is a prerrogative decision of environmental authorities, that evaluate requirements for the protection of fish stock and the assurance of aquaculture. The partial suppression of vegetation in the accumulation basin also tends to delay greenhouse gas emissions (CO 2 , CH 4 and N 2 O), once decomposition will be processed within the aquatic environemnt and refractory biomass usually decays slowly (Aprile et al, 1999;Bianchini Junior & Cunha-Santino, 2011). Inclusively, the submersion of stems in reservoir water is a current and empirical practice of wood preservation.…”

“…However, wood degradation can be evaluated through mathematical models for which equations are proposed to verify the reduction of its properties. There are also kinetic models that consider wood decay properties due to oxidative processes in terrestrial and aquatic environments (APRILE et al, 1999). On the other hand, there are also models for assessing deterioration of wooden poles above the soil (SCHEFFER, 1971).…”
