Solid waste disposal is one of those rare endeavors where success breeds anonymity. To the credit of local waste management agencies and contractors‚ their service is highly inconspicuous in northeastern Illinois. This low profile belies the importance and complexity of efficient trash collection‚ and veils many impacts of municipal solid waste (MSW) policy from our everyday lives. Like other environmental elements‚ waste does not follow regional borders. From an email survey that we conducted

Chromatography serves mainly as a tool for the examination and separation of mixtures of chemical substances. Chromatography is using a flow of solvent or gas to cause the components of a mixture to migrate differently from a narrow starting point in a specific medium‚ in the case of this experiment‚ filter paper. It is used for the purification and isolation of various substances. There are two phases in chromatography: 1. Stationary Phase – a solid that does not move. In this experiment was the chromatography
