Subject: I need your advice.

I was nominated as the coordinator of the studentsí laboratory manual Review committee and I am to work with this long list of chemicals and materials.
  Part of the assignment of my committee is to 
  (1.)  Identify some of these chemicals which are carcinogenic, poisonous and are no more expected to be used in the laboratory again or are having regulatory restriction placed on them.
  (2.)  Profer alternative Chemical to be used to achieve the same aim in the laboratory.
  (3.)  See possible and safe mean of discarding the ones in stock.
  Please, I will appreciate you contributions on any of these chemicals.
  I work in the pharmacognosy Department.
  Thanks.
