近几十年来，人们的注意力集中在开发基于有机硅聚合物的无毒污垢释放涂料，作为有毒防污涂料的替代品。随着污垢释放涂料获得市场份额，它们将导致有机硅对环境的污染。本文报道了八种模型聚硅氧烷和三种市售防污涂料对海胆和日本青鳉胚胎发育的影响。我们使用模型涂层，因为它们具有已知的组成，并且从这些涂层中浸出的市售组分和分子已部分表征。商业污垢释放涂料据称是无毒的，成分是专有的。我们的目标是将经过充分研究的模型动物的胚胎暴露于涂层，以确定从涂层中浸出的复杂混合物是否影响发育。选择海胆是因为发育迅速，胚胎可以进入表面的防滑层。之所以选择青鳉，是因为雌性青鳉把粘性的卵放在臀鳍上，然后把它们刮到表面上。将胚胎限制在24孔板中的涂层上的水中。新鲜的模型涂料没有影响海胆的发展，而商业污垢释放涂料抑制发展。鱼胚胎延迟孵化，增加孵化的死亡率和显着降低孵化的能力，以膨胀的鱼鳔和减少孵化成功的所有涂层。在流动的海水中浸泡一个月以模拟在海洋环境中的初始应用后，海胆胚胎在放置在模型硅树脂上时死亡。商业涂料的影响减少，但包括延迟发展。与新鲜涂层相比，沥滤涂层对鱼胚胎的影响减少，包括孵化成功率降低，幼体存活率降低以及无法为商业涂层的鱼鳔充气。这些发现表明，与医学结论相似，有机硅涂层中的化合物浸出会影响开发，该主题值得研究。(C)2012爱思唯尔有限公司版权所有。
In recent decades attention has focused on the development of non-toxic fouling-release coatings based on silicone polymers as an alternative to toxic antifouling coatings. As fouling-release coatings gain market share, they will contribute to environmental contamination by silicones. We report effects of eight model polysiloxane and three commercial foul-release coatings on embryonic development of sea urchins and fish, Japanese medaka. We used model coatings because they have known composition and commercially available components and molecules leaching from these coatings have been partially characterized. The commercial fouling-release coatings are purported to be non-toxic and components are proprietary. Our goal was to expose embryos of well studied model animals to the coatings to determine if the complex mixtures leaching from the coatings impact development. Urchins were chosen because development is rapid and embryos can enter the non-slip layer over surfaces. Medaka was chosen because the female deposits the sticky eggs onto the anal fin and then scrapes them off onto surfaces. Embryos were confined in water over coatings in 24 well plates. Fresh model coatings had no effect on urchin development while commercial fouling-release coatings inhibited development. Fish embryos had delayed hatching, increased mortality of hatchlings and dramatically decreased ability of hatchlings to inflate the swim bladder and reduced hatching success on all coatings. After one-month immersion of coatings in running seawater to simulate initial application in the marine environment, sea urchin embryos died when placed over model silicones. Effects of the commercial coatings were reduced but included retarded development. Effects on fish embryos over leached coating were reduced compared to those of fresh coating and included decreased hatching success, decreased hatchling survival and inability to inflate the swim bladder for commercial coatings. These findings suggest, similar to medical conclusions, compounds leaching from silicone coatings can impact development and the topic deserves study. (C) 2012 Elsevier B.V. All rights reserved.
