The international electronics industry.

High-technology microelectronics has a major presence in countries such as China, India, Indonesia, and Malaysia, now the third-largest manufacturer of semiconductor chips. The migration of European, Japanese, and American companies accommodates regional markets. Low wage rates and limited enforcement of environmental regulations in developing countries also serve as incentives for the dramatic global migration of this industry. The manufacture of microelectonics products is accompanied by a high incidence of occupational illnesses, which may reflect the widespread use of toxic materials. Metals, photoactive chemicals, solvents, acids, and toxic gases are used in a wide variety of combinations and workplace settings. The industry also presents problems of radiation exposure and various occupational stressors, including some unresolved ergonomic issues. The fast-paced changes of the technology underlying this industry, as well as the stringent security precautions, have added to the difficulty of instituting proper health and safety measures. Epidemiologic studies reveal an alarming increase in spontaneous abortions among cleanroom manufacturing workers; no definitive study has yet identified its cause. Other health issues, including occupational cancer, are yet to be studied. The microelectronics industry is a good example of an industry that is exported to many areas of the world before health and safety problems are properly addressed and resolved.
