NICNAS provided technical advice to OASCC on a fee-for-service basis for hazard classification and occupational exposure standards for several chemicals. NICNAS reviewed the health effects data for beryllium and beryllium compounds and made recommendations to revise the occupational exposure standard and hazard classification for these chemicals. NICNAS also provided updated reviews of the health effects of benzene and the refrigerant chemical 2,2-dichloro-1,1,1-trifluoroethane (HCFC-123) and made recommendations with respect to occupational exposure standards.

NICNAS was commissioned by the Attorney General's Department (AGD) to collate information on the introduction volumes and uses of 38 chemicals that can be used as precursors in the manufacture of illicit drugs. The purpose of this activity was to derive the nature and extent of industry application of these substances so as to consider approaches to various authorities for rescheduling or amendments to existing legislation. The report was finalised and provided to AGD in August 2005.

NICNAS has also begun working with AGD on building a central repository of information about industrial chemicals known to be used as precursors in the manufacture of illicit drugs.

Multiple Chemical Sensitivity (MCS) is the term most frequently used to describe a cluster of medically unexplained symptoms exhibited by certain individuals resulting predominantly from low level exposure to environmental chemicals. NICNAS is cooperating with OCS in reviewing available scientific evidence relating to potential causes, reported adverse effects, clinical manifestations, diagnosis and treatment of MCS. As part of this review, specialist clinical medical practitioners have been engaged to investigate and report on current diagnostic criteria and clinical treatment/management of MCS. The MCS review will consider appropriate regulatory responses to MCS, as well as identify further research needs. Community consultation on this matter will proceed in early 2006-07.
