Recent edit to Environmental testing
Hello, and welcome to Wikipedia. I wanted to let you know that I removed one or more external links you added to the Environmental testing article, because they seemed to be inappropriate for an encyclopedia. You may find our linking guidelines helpful in this regard. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you!

Please stop adding inappropriate external links to Wikipedia. It is considered spamming and Wikipedia is not a vehicle for advertising or promotion. Because Wikipedia uses nofollow tags, additions of links to Wikipedia will not alter search engine rankings. If you continue spamming, you may be blocked from editing Wikipedia.
