Consumer product exposures calculation details

The long term (chronic) consumer product exposure assessment through oral ingestion, dermal contact and inhalation via personal care products, household cleaning products and do-it-yourself products is following the methodology as developed in PACEM and RSExpo. MCRA applies in principle the equations as used in PACEM and RSExpo.

Consumer product exposures are generated using an existing set of individuals, see module consumer product use frequencies. Together with information on the application amounts the exposure of personal care products, household cleaning products and do-it-yourself products in various European countries is estimated.

Consumer product exposure

The calculation for exposure to consumer products is:

\[\mathtt{E_{consumer-product}} = \mathtt{frequency} \cdot \mathtt{amount} \cdot \mathtt{concentration} \cdot \frac{ \sum_{route=1}^{p} EF_{route}} {BW} \cdot \mathtt{occurrence \% /100}\]

Parameters used in the equation

\(\mathtt{E_{consumer-product}}\): average daily external exposure of an individual to substances in consumer products (default in \(\mu g/kg \, bw /day\))

\(\mathtt{BW}\): body weight of the individual (default in \(kg\))

\(\mathtt{amount}\): application amount (\(mg\))

\(\mathtt{concentration}\): substance concentration in consumer product (\(mg/kg\))

\(\mathtt{frequency}\): use frequency of een individual

\(\mathtt{occurrence \%}\): occurence percentage, % of products with substance (default 100%)

\(\mathtt{EF_{route}}\): exposure fraction of a specific route (substance specific)
