The common contaminants are humic and fulvic acids, which are organic acids present in soil that are produced by the microbial degradation of plant or animal tissues. Fossil samples from Green Cave show a trend for increasing specimen age with increasing radiocarbon dating bone collagen from the cave entrance see Table 1.
