WebThe key properties used in the published naphthalene risk assessment (EC, 2003) are summarised in Table 1. More recently, an assessment of coal-tar pitch, high temperature (CTPHT) has been carried out under the ESR programme (ECB, 2007). Naphthalene is a component of CTPHT, and the latter assessment uses slightly different property values1 … WebNaphthalene is released to the air from the burning of coal and oil and from the use of mothballs. Coal tar production, wood preserving, and other industries release small amounts. (1) Typical air concentrations of naphthalene in cities are about 0.18 parts per billion (ppb). (1) Naphthalene has also been detected in tobacco smoke. (1)
