Perfumes and scented products are composed of toxic chemicals like acetone‚ toluene‚ ethyl acetate‚ formaldehyde and ethanol that are found on any list of toxic and hazardous chemicals. All these and other chemicals used in the manufacture of personal care products have been shown in animal studies to cause serious health problems

This paper is about the neurological problems that could arise following the use of recreational drugs and substances from a neurological perceptive. In this paper I cover general categories of recreational drugs verses specific drug by drug classifications. I present this information with minimal consideration of the added complications of the interactions between recreational drugs‚ alcohol‚ pharmacological products‚ and predisposing or current mental and physical health.

Gasoline is defined by Wikipedia as a "petroleum-derived liquid mixture consisting mostly of aliphatic hydrocarbons and enhanced with aromatic hydrocarbons toluene‚ benzene or iso-octane to increase octane ratings‚ primarily used as fuel in internal combustion engines" (Wikipedia‚ 2010). Most automobiles rely on this type of gasoline today. At gas stations‚ the general grades available are 87‚ 89‚ and 93. Each

Introduction In an E1 reaction‚ where E stands for elimination and 1 stands for unimolecular. The breaking of the C-LV bond is completed before any reaction occurs between the base to lose a hydrogen and form the carbon-carbon double bond [1]. When the more substituted alkene is the dominant product‚ the reaction follows Zaitsev’s rule. Zaitsev’s rule states that the major product of a β-elimination reaction is the most stable alkene [1].Acid-Catalyzed Dehydration is the elimination of a

Plastic bottles must not be used for sampling as there is a risk of a build-up of static charge and the container cannot be earthed to ground. Crude oil samples can only be sampled into earthed steel sampling containers. Earth leads must be used to reduce the potential for static ignition 3. Gas monitors should be used where hydrocarbon gas may be evolved.

Nowadays‚ people are captivated by cheap and strong cleaning products‚ which contains hazardous chemicals and may potentially lead to cancer or other serious health problems. Especially‚ for the families with children‚ keeping standard quality cleaning products is same as keeping a poison in their houses.
