Welcome to Wikipedia. Everyone is welcome to contribute to the encyclopedia, but when you add content (particularly if you change facts and figures), as you have to the article Derived no-effect level, please cite a reliable source for the content you're adding or changing. This helps maintain our policy of verifiability. Take a look at Citing sources for information about how to cite sources and the welcome page to learn more about contributing to this encyclopedia. Thank you. PDCook (talk) 16:22, 31 December 2009 (UTC)

Welcome to Wikipedia. Although everyone is welcome to contribute constructively to the encyclopedia, you may not know that Wikipedia has a Manual of Style that should be followed to maintain a consistent, encyclopedic appearance. Using different styles throughout the encyclopedia, as you did in European Union System for the Evaluation of Substances, makes it harder to read. Please take a look at the welcome page to learn more about contributing to this encyclopedia. Thank you. PDCook (talk) 19:30, 31 December 2009 (UTC)

advice
Please read see our guide to writing Wikipedia articles. You need to show notability with references providing substantial coverage from 3rd party independent published reliable sources, print or online, but not blogs or press releases, or material derived from press releases  Do not copy from a web site or previously published material-- first it's a copyright violation, but, even if you give us permission according to WP:DCM, the tone will not be encyclopedic and the material will not be suitable. For further information see our FAQ about businesses, organizations, and articles like this. I advise you to improve the articles you have been writing very quickly, before they  gets nominated for deletion.
 * In particular, consider if the articles can be merged. There can still be redirects from the individual titles--it would probably make for a much clearer and stronger presentation.  DGG ( talk ) 04:39, 1 January 2010 (UTC)

Articles for deletion nomination of Chemical Safety Report
I have nominated Chemical Safety Report, an article that you created, for deletion. I do not think that this article satisfies Wikipedia's criteria for inclusion, and have explained why at Articles for deletion/Chemical Safety Report. Your opinions on the matter are welcome at that same discussion page; also, you are welcome to edit the article to address these concerns. Thank you for your time.Please contact me if you're unsure why you received this message. NJA (t/ c)  11:53, 19 January 2010 (UTC)
