- Details on results:
- NIOSH (NOES Survey 1981-1983) has statistically estimated that 162,623 workers (16,364 of these are female) are potentially exposed to magnesium in the US. Occupational exposure to magnesium occur through inhalation and dermal contact with this compound at workplaces where magnesium is produced or used (SRC). Monitoring data indicate that the general population is exposed to magnesium compounds via inhalation of ambient air, ingestion of food and drinking water, and dermal contact with this compound and other consumer products containing magnesium compounds.

*(1) By survey design, not all 2-digit SICs were surveyed. (2) The estimates for each 2-digit SIC apply only to the 3- and 4-digit SICs surveyed within the 2-digit SIC. Not all SICs were surveyed. (3) When using the estimates, standard errors associated with estimates should be considered. (4) Potential exposures to a chemical agent are categorized as actual (i.e., the surveyor observed the use of the specific agent) or tradename (i.e., the surveyor observed the use of a tradename product known to contain the specific agent). The estimates presented in the table combine both categories.
Applicant's summary and conclusion
- Conclusions:
- NIOSH (NOES Survey 1981-1983) has statistically estimated that 162,623 workers (16,364 of these are female) are potentially exposed to magnesium in the US. Occupational exposure to magnesium occur through inhalation and dermal contact with this compound at workplaces where magnesium is produced or used (SRC). Monitoring data indicate that the general population is exposed to magnesium compounds via inhalation of ambient air, ingestion of food and drinking water, and dermal contact with this compound and other consumer products containing magnesium compounds.
- Executive summary:
NIOSH (NOES Survey 1981-1983) has statistically estimated that 162,623 workers (16,364 of these are female) are potentially exposed tomagnesium in the US. Occupational exposure tomagnesiumoccur through inhalation and dermal contact with this compound at workplaces wheremagnesiumis produced or used (SRC).
Monitoring data indicate that the general population is exposedto magnesium compounds via inhalation of ambient air, ingestion of food and drinking water, and dermal contact with this compound and other consumer products containingmagnesium compounds.
