Streszczenie
The purpose of the examination was a physicochemical analysis of paint traces which could turn out to be helpful in the reconstruction of a car accident. The key question in this case was establishing whether the driver of a car parked by the roadside contributed to the falling over of a bicyclist passing by. As a consequence of the accident, the bicyclist suffered a serious injury. At the beginning nothing indicated that a small smear on the brake lever of the bicycle could have been related to the accident. Optical and physicochemical analysis revealed that the material making up the smear could be paint. As a consequence of these findings, careful examination of the left front door of the car was carried out and a little damage was revealed. Further examinations, including a comparative analysis of the chemical composition of samples taken from the car paint and from the smear on the bicycle, confirmed their consistency.
