[Tetrachlorethene pollution--results of follow-up of neighbors of chemical dry cleaning establishments and current legal developments].

New legal provisions set a limiting value of 0.1 mg TCE/m3 air in flats. Follow-up examinations by the Public Health Office Bremen show again that so far this limit can not be complied with in flats adjacent to dry cleaners. Interviews with affected residents give no hint for a change in utilisation habits. The Upper House of the German Federal Parliament has taken the legislative initiative for a complete prohibition of TCE in consequence of the fundamental problem of limiting values.
