Toxic Properties and Developmental Defects

Special care has to be taken if the embryo-toxic effects are caused by concentrations which are not detectable in the pregnant woman. In these cases, special workplace measures are necessary. Teratogenic effects are exclusively anatomical malformations. Statistically relevant delays in the embryonic or fetal growth without modifications of the organs are subsumed to the developmental effects. 

Developmental defects are aU damaging effects on the evolution of the tinhorn child, which are activated during the pregnancy and manifested peri- or postna-taUy. 

In developmental toxic effects activated at the workplace, the most important factors are 

AU physical radiation with an ionizing potential has to be regarded as dangerous for the embryo or fetus. The most serious damage known is from gamma rays and X-rays.
