Feldt et al.

Medical-, socio-demographic information Short physical examination Urine samples | Clinical symptoms (occurring in the last 4 weeks) such as cough, chest pain and dizziness/vertigo were reported significantly more frequently in e-waste workers compared to controls. |
Neitzel et al. [2020] | Cross-sectional: exposed e-waste worker (EWW), Thailand, July 2016 | Overall n = 119/120* EWW (n = 58 female, n = 61 male) * n = differing information for overall participants | Questionnaire incl. Socio-demographic information and self-reported health status Blood & urine samples with concentrations of calcium (Ca), creatinine, metal levels (cadmium (Cd), lead (Pb), manganese (Mn); GFR, FECa% Health & anthropometic measurements | Blood levels of cadmium and lead were significantly higher in males. Regression analysis of urinary GFR and lead among informal EWW showed a significant positive correlation. |
