title: [Twenty-years health surveillance of workers in dipterex packaging].
abstract: Data of health surveillance from 1970 to 1989 for the workers employed in dipterex packaging were collected and statistically analyzed with a microcomputer by scoring their whole blood choline esterase activities and symptoms and signs. Results showed working environment improved and air pollution and absorption of pollutants via skin decreased with technology innovation and longterm hygienic supervision, monitoring and health surveillance in the factory. Incidence of dipterex poisoning in workers employed in the department of pesticide packaging lowered significantly, from 25.26% in the early 1970's to 5.17% in late 1970's and to 1.85% during 1980's, with periodical physical examinations for them, and timely management of the patients with poisoning and the cases at high risk.
