Scientists at CSIRO in Australia have produced organoborates which read more can be a great deal more proof against leaching, though nevertheless giving timber with great defense from termite and fungal assault.[seventeen][eighteen] The expense of the production of these modified borates will Restrict their prevalent get-up but They're more likely to be suitable for particular specialized niche applications, Specially in which minimal mammalian toxicity is of paramount relevance.
