WitrynaFire Protection Association) rating for flammability.5 We can smell naphthalene in air at a concentration of 84 parts naphthalene per billion 6 (ppb) of air and while we can smell it in water at a concentration of 21 ppb6. Both of these formulations have strong, pungent, sickly-sweet odour often associated with mothballs. Most naphthalene is derived from coal tar. From the 1960s until the 1990s, significant amounts of naphthalene were also produced from heavy petroleum fractions during petroleum refining, but present-day production is mainly from coal tar. Approximately 1.3M tons are produced annually. Naphthalene is the most abundant single component of coal tar. The composition of coal tar varies with coal type and processing, but typical coal tar is about 10% naphthalene by weight. I…
