Table 3.
BDE values expressed as ng/g of dust, reported for each congener, in the different indoor environments (Columns 2–6). Columns 7 and 8 show the total average value of the domestic dust average (D1 and D2) and workplace dust average (D3–D5). The Column 2–8 values were associated to a method RSD of 15%. Results are compared with other studies (last two columns) reported as median (min.–max.) concentrations.
