W ostatnich latach coraz częściej do oceny jakości środowiska wykorzystuje się tzw. narzędzia zintegrowane, czyli połączenie analiz chemicznych z mikrobiotestami. Umożliwić to ma identyfikację potencjalnych źródeł toksyczności w analizowanych próbkach. Niestety, znalezienie wyraźnych korelacji pomiędzy wynikami analiz chemicznych oraz oszacowanymi parametrami toksyczności nie jest prostym zadaniem i nastręcza wiele trudności.

Ground tire rubber (GTR) has been used as a sustainable low-cost modifier in various composites. However, due to the hydrophobic nature of GTR, it is in compatible with most matrices and results in deterioration in both mechanical and physical properties of composites. This necessitates pre-modification of the powdered rubber to improve the interfacial bonding at the rubber-matric interface. The most common GTR modification research...
