Comparison of extractable DNA from bone following six-month exposure to outdoor conditions, garden loam, mold contamination or room storage.

Femur bone sections from a single donor were exposed for six months to (i) outdoor conditions (exposure to sun, rain, etc.); (ii) water-vapour saturated environment favourable to mould proliferation and (iii) humic-garden soil. Following these treatments, DNA was extracted and yields were compared with that of a control bone fragment kept under optimal laboratory storage conditions.
