【医药小常识】
吃火锅不要超过1个半小时
  
  吃火锅不要超过1个半小时,否则会吃进有毒的化学物质,甚至还可能致癌。
  火锅汤底烧煮90分钟后,亚硝酸盐(Nitrite)的含量将15毫克。人体一次摄取亚硝酸盐超过200克就会缺氧,出现急性中毒。
  在烧煮过程中,食物还会产生致癌物质亚硝胺(Nitrosamines)。
  一些食物如肉类,经长时间高温烹煮后就会产生有害物质,尤其是碳烧或碳烤。
  任何食物经长时间烹煮后都可能产生亚硝酸盐和致癌物亚硝胺,只是产生的数量难测。”
  吃火锅最好不断换汤底,肉类也不要在高温的汤底煮太久。(此资讯仅供参考)

10 Simple Ways to Connect to Your Teen

Mrs Ismail who is in-charge of Environment Education would like to appeal to PSG parents' support on the following: This year the school will be embarking on re-using or recycling used glass bottles - wine ketchup, drinks, essence of chicken bottles etc and containers or jars to be used as decorative items. This is a student initiated project. Please help us in our effort towards waste minimisation either by donating the glass bottles and/or containers. We will get a vendor to help us with the terrarium making which will be placed in each class. Parents could either bring the bottles/containers on 28 Feb Lo Hei (Sec 1 esp) or drop them off at the boxes outside the school General office. Thank you very much. Looking forward to the support in this project.
