“…In 1910, Paul Ehrlich introduced a new arsenic-based drug to treat syphilis, the organoarsenic compound arsphenamine, sold commercially under the name of Salvarsan, which was In the first half of the nineteenth century, inorganic pesticides (herbicides, insecticides) were normally used in agriculture and were found to be stable in the environment having an affinity to water [32]. Chromated copper arsenate is a chemical additive used traditionally to preserve wood from decomposing, due to humidity, insects, and microbial agents (biodeterioration) [33,34]. Finally, arsenic has a long history as a human poison and paradoxically, as a therapeutic agent [18,35].…”

Arsenic (As) is quite an abundant metalloid, with ancient origin and ubiquitous distribution, which represents a severe environmental risk and a global problem for public health. Microbial exposure to As compounds in the environment has happened since the beginning of time. Selective pressure has induced the evolution of various genetic systems conferring useful capacities in many microorganisms to detoxify and even use arsenic, as an energy source. This review summarizes the microbial impact of the As biogeochemical cycle. Moreover, the poorly known adverse effects of this element on eukaryotic microbes, as well as the As uptake and detoxification mechanisms developed by yeast and protists, are discussed. Finally, an outlook of As microbial remediation makes evident the knowledge gaps and the necessity of new approaches to mitigate this environmental challenge.

“…An average of this magnitude is used by APVMA to determine the level of risk, or lack of risk that might be posed to children playing on CCA-treated timber structures in Australia. Moreover, the exposure to As by children playing on CCA-treated structures as been estimated using handloading data [24].…”

A review on research has been made regarding recent developments aiming at reducing the negative environmental impact (because sometimes it might be positive) derived from industrial manufacturing processes of lignocellulosic-derived products, from their utilization, and also from their disposal at the end of their life. The most common journals of the wood science and environmental fields have been screened and relevant papers on this topic are referred and commented. This paper covers mainly lignocellulosic-based products taken as materials. That is saying, materials of common use and that were made incorporating mostly raw materials from forest or agriculture plants. Examples of such products are particleboard, waferboard, MDF, OSB, plywood and lignocellulosic-plastic composites. Excluded from this review are utilizations of biomass for heat=energy production or its processing for chemicals (e.g., ethanol). Important issues for this paper are: lignocellulosic wastes and sub-products recycling, Wood preservation environmental issues, VOCVolatile Organic Compounds emissions, adhesion of wood and LCA -Life-Cycle Assessment of forest products.

“…Many wood protection agents and methods have been tried to protect wood against biological factors, such as fungi, insects, termites, and molds. Chromated copper arsenate (CCA) formulations have been used to extend the service life of wood for many decades due to their biological toxicity (Barraj et al 2009). After 2003, with increasing environmental pressures and legal regulations, CCA was prohibited in residential applications due to its health risks (Clausen 2004).…”

Propolis is an important antifungal agent found naturally in beehives and used as a food supplement for many purposes. This study aimed to use methanolic propolis extract (MPE) as a treatment material as an antifungal agent for wood preservation. Scots pine and paulownia woods were exposed to Trametes versicolor and Neolentinus lepideus fungi for 12 weeks, and untreated woods were used as the controls. Compared with the control, paulownia wood exposed to N. lepideus had a 47.2% mean mass loss, while the treated wood with 7% MPE had an 11.6% mean mass loss. In addition, a 27.2% mass loss occurred with the control for Scots pine when exposed to N. lepideus, and a 2.5% mass loss occurred with the 7% propolis-treated specimens. Total phenolic content and the phenolic profile of the raw propolis samples were also analyzed. Scanning electron microscopy images showed that the propolis extracts still remained in the wood cells without being degraded after the fungal destruction and the propolis-treated specimens were more durable against fungal decay compared to the untreated control specimens. The results from this study indicated that propolis could be used as an environmentally compatible and natural wood preservative to protect wood against fungal attack.
