European and Canadian asbestos companies have long taken advantage of the lack of regulation of the asbestos industry in developing countries. Their activities exploit vulnerable workers whose lack of medical care may result in a silent epidemic of asbestos-related diseases. At this time, virtually all cases of asbestosis and asbestos-related cancers are not identified, reported, or compensated in developing countries. Brazil provides a compelling example of this growing problem. To stem the epidemic of asbestos-related diseases, Brazil, and many other countries, must adopt the total ban on asbestos use now in effect in more developed countries. Obstacles to accomplishing this in developing countries are daunting.
ABSTRACT
Embryos of the Sea Urchin Paracentrotus lividus were incubated for different periods of time in various concentrations of Zinc-ethylenebisdithiocarbamate (ZINEB) in artificial (or natural) sea water. Dramatic developmental modifications have been observed after 48 hour treatment with 0.4 ug/ml ZINEB solution. The abnormalities concern the formation of spiculae.
