End-grain influence on VOC emissions from kiln-drying loblolly pine

This project investigated the influence of the end grain on volatile organi c compound (VOC) emissions. Two lumber lengths and two end conditions were used to evaluate the end effect. The influence of season of harvesting and processing on VOC emissions was also investigated. End effect was not found to be statistically significant. Seasonal influence, however, was found to be statistically significant with respect to VOC emissions. This seasonal influence is different from that noted in earlier work (8,9). This differen ce suggests the need for additional study regarding the influence of proces sing season on VOC emissions.
