We selected three companies of different sizes and degrees of automation for this study (Table 1) among a total of 30 companies performing e-waste recycling between 2007 and 2009 in Sweden. They all recycled similar types of goods, such as TV-sets and computers (flat screen and CRT screens), electronic tools, toys, and small and large household appliances (not including freezers and fridges). In total, 65 workers (71%) in the selected companies agreed to participate in the study. Of these, 55 (85%) worked with recycling and 10 (15%) were based in an office. We assessed the exposure on two occasions, 6 months apart. One company did not participate in the second round of measurements due to bankruptcy; therefore, only 32 workers participated in the second part of the study.
