Smoke-dried bonito is a traditional Japanese processed fish product containing considerable amounts of polycyclic aromatic hydrocarbons (PAHs). Their concentrations generally exceed the maximum levels under EU regulations. Although halogenated PAHs (XPAHs) have attracted attention owing to their high toxicities, no information on the occurrence of XPAHs in smoke-dried bonito is available. In this study, we investigated the occurrence of PAHs and XPAHs in smoke-dried bonito purchased in the Japanese market in 2020 and evaluated the contamination levels in terms of concentrations and incremental lifetime cancer risks (ILCRs). The total concentrations of PAHs were 419–1070 μg kg–1 and those of XPAHs were 0.306–1.01 μg kg–1. Because smoke-dried bonito is consumed in low amounts, the ILCR of PAH4 via dietary consumption of smoke-dried bonito was the lowest among those of other smoked foods. Smoking by hot-plate heating of wood chips should be one of the effective countermeasures to reduce PAH contamination.

“…Unfortunately, the reports lack data on the conditions of particle shredding and their geometry. A complex analysis of the particles is justified since their properties determine the properties of the particleboards (Nemli et al 2007, Nazerian et al 2011, Azambuja et al 2018, Bardak et al 2019. The particles properties depend on the material characteristics and the conditions of shredding process (Hernández et al 2014).…”

The present work regards an attempt to obtain particles from the post-industrial pine plywood in a single-shaft shredder. A screen mesh size determines the wood particles characteristics. In the work 10-, 14-, 25and 38-mm mesh size screens were used. The urea-formaldehyde (UF) and phenol-formaldehyde (PF) bonded plywood were shredded separately, so that the effect of the binder type could be analyzed. The determined fractional composition, bulk density, dimensions and surface area of the particles were compared to the industrial virgin pine particles dedicated to the core layer of particleboards. The results showed that the particles obtained from a 14-mm mesh screen exhibited properties closest to those found for the virgin particles.

Particleboard, engineered wood products as part of a large family of wood composite materials, developed in use mainly in the 1950s and 1960s to utilize inferior wood and wood waste when good-quality wood was in short supply; the annual production capacity worldwide is over 100 million m3. It is also necessary to have a lot of wood raw material for its production, although raw material resources are limited on our planet. In addition to the main wood species, it is therefore possible to think about the wider use of alternative, lesser-known European species of alder, larch, and birch in particleboard production. These three wood species represent an eco-friendly and sustainable wood alternative to the conventional wood raw materials used. This review confirms the diversity of the use of these three species in different fields and proves their suitability in relation to particleboard production. Fundamental research is ongoing in certain universities to determine the proportional shares of use of these tree species in particleboard (in a certain weight proportion in their core layers) for the purpose of formulating the correct technology shares and rules for their application in the wood-based panel industry.
