- Abstract
The article presents a study that determines whether zygote exposure to the pure estrogen 17ß-estradiol would result in developmental anomalies similar to those exposed to environmental proestrogen methoxychlor (MXC). Sea urchins or strongylocentrotus purpuratus were maintained in an aerated and refrigerated laboratory aquarium. Gamete shedding was induced through intracoelomic injection and gametes were collected in artificial seawater (ASW). ASW was prepared basing on the formulae of Marine Biological Laboratory. By light microscopic examination, 100 embryos were scored in triplicate. Results showed that the chronic exposure of embryos to 17ß-estradiol and MXC exposure had different effect on gastrulation.
