“…Os danos causados pelas brocas marinhas estão relacionados ao apodrecimento e perda de área em madeira que a estrutura sofre. Os moluscos penetram na madeira e abrem túneis no interior dela, o que em casos mais avançados, compromete o bom funcionamento do material, levando ao colapso ou quebra (LINS et al, 2021). Por outro lado, os crustáceos causam danos de uma maneira diferente, mas que também levam ao apodrecimento e perda de área em madeira, a ponto de enfraquecer a estrutura.…”

“…Lins (2020) testou diferentes tratamentos alternativos no litoral paranaense e os que apresentaram melhores desempenhos foram os de borracha impermeabilizante com e sem a adição de sílica. Além destes, outras pesquisas foram desenvolvidas para estudo da preservação da madeira (SERPA, 1980) e para o desenvolvimento de uma metodologia de quantificação da perda de área causada por brocas marinhas (LINS et al 2021).…”

Esse artigo objetivou realizar a compilação das publicações relacionadas a bioderetioração da madeira em ambiente marinho no Brasil até 2019, apresentando uma revisão bibliométrica e o estado da arte sobre este tema. A pesquisa foi realizada utilizando três bases de dados: Scielo, Web of Science e Scopus. Os artigos passaram por uma triagem resultando em 17 documentos. Os principais parâmetros de avaliação foram as instituições que contribuíram para a pesquisa; distribuição das publicações ao longo dos anos; objetivo da pesquisa; e se o tema tecnologia da madeira foi abordado. O primeiro registro de publicações com brocas marinhas no Brasil foi na década de 1980, mas não houve um aumento de produção científica ao longo dos anos. Além disso, nenhum dos estudos avaliados teve a biodeterioração e preservação da madeira como foco, sendo mais direcionados para tópicos como ecologia, fisiologia e taxonomia dos xilófagos marinhos. Existe a necessidade estimular pesquisas voltadas para a biodeterioração e preservação da madeira relacionadas a brocas marinhas, tendo em vista a lacuna de estudos com esse tema, bem como a importância desses organismos no âmbito ambiental e econômico. Palavras-chave: xilófagos marinhos; preservação da madeira; moluscos; crustáceos. Marine borers and wood biodeterioration in Brazil: a systematic review ABSTRACT: This paper aims to carry out a compilation of publications on wood biodeterioration by marine borers in Brazil until 2019. It presents a bibliometric review and offers the state of the art on the subject. The research was carried out in three databases: Scielo, Web of Science and Scopus. The articles were screened resulting in 17 documents. The main evaluation parameters were the institutions that contributed to the research; distribution of publications over the years; aims; and if the subject wood technology was addressed. The analysis suggests that the first record on the subject dates from the 1980s, but there is no increase of studies published over the years. In addition, none of the studies focus on wood biodeterioration and preservation, being more directed towards topics such as ecology, physiology, and taxonomy of marine xylophages. There is a need to encourage research focused on wood biodeterioration and preservation related to marine borers, given the lack of studies on this topic, as well as the importance of these organisms in the environmental and economic sphere. Keywords: marine xylophages; wood preservation; molluscs; crustaceans.

Evaluation of marine borers attack on treated wood in Southern Brazil

et al. 2023

Wood in marine environments requires protection against xylophagous, and to increase the effectiveness of the preservatives, it is first necessary to know environmental conditions and species of wood borers present. The durability of treated Pinus taeda wood against the attack of marine borers in different environments was investigated, with (1) burnt oil, by the hot-cold bath method; (2) paraffin, by the Bethell method; (3) superficial burning of the wood with oil application, known as shou sugi ban technique; and (4) impermeable rubber, with and without the addition of silica, by immersion. The experiment was adapted from the standard EN 275 (1992) and carried out in three areas, one located in a river and two in estuarine coastal areas of the Paranaguá Bay (Brazil). Based on the percentage of lost wood area, the treatment with impermeable rubber with the addition of silica showed the best performance at the local 1 site (26.3%). At the local 2 site, treatments with impermeable rubber with and without the addition of silica had the lowest percentages of loss, with mean values of 13.95 and 12.65%, respectively. The other treatments had losses above 30%, being classified as severe damage, meaning they are not suitable for this use.

The low natural durability properties of some types of wood indicate the need for treatments to enhance the resistance of these materials to biological decay. In the sea, this resistance is necessary due to the actions of wood-boring mollusks and crustaceans. These treatments must be effective without harming the environment. Wood thermal treatment should be evaluated for this purpose. Therefore, the aim of this study was to evaluate the deterioration characteristics of thermally treated wood samples from Corymbia citriodora and Eucalyptus urophylla under the actions of marine wood borers. A method was proposed to aid in this assessment. Ten samples of these woods, both untreated and thermally treated, were submerged in the sea, each at a depth of 2.5 meters, for five months. After this period, the external borehole number, mass loss, and central flat lesion parameters of the samples were evaluated. Both the thermally treated and untreated wood samples of C. citriodora showed less deterioration than those of E. urophylla, with fewer boreholes, smaller lesioned areas, and lower mass losses. Compared with untreated wood and E. urophylla wood, thermally treated C. citriodora wood exhibited some resistance to marine wood borers. It was concluded that C. citriodora wood was naturally more resistant to marine wood borers than E. urophylla wood. Moreover, thermal treatment increased the boring resistance of C. citriodora wood while increasing the susceptibility of E. urophylla wood. The digital measurement of flat lesions was proven to be an auxiliary and promising method for evaluating the deterioration process.
