Introduction: The chemical industry has become one of the largest manufacturing industries in the world since the beginning of the 21st century (Murmann‚ 2003). They convert raw materials such as oil‚ natural gas‚ air‚ water‚ metals‚ and minerals into more than 70‚000 synthetic chemicals (United States Department of Commerce‚ n.d.). Heavy demands on chemicals allowed prosperity of materials goods and had brought convenience for many people. Now they can be found everywhere around world‚ and even

No human data was found on teratogenicity or reproductive effects of Dicamba (NPIC‚ 2012). The chart (NPIC‚ 2012) below contains the toxicity classification for Dicamba regarding the acute oral‚ inhalation‚ dermal‚ primary eye irritation‚ and primary skin irritation effects. It is important to note that not a lot of information is available regarding the chronic toxicity of Dicamba in humans‚ the U.S. EPA has not found any evidence regarding Dicamba disrupting the Endocrine system‚ and Dicamba is

Cultural‚ Biological‚ Physical and Chemical An entirely different perspective is brought into focus as we consider some of the environmental hazards that accompany industrial growth and intensive agriculture. Some of the most dangerous hazards in this world are the outcome of purely voluntary behavior --- in particular‚ smoking tobacco and engaging in risky sexual activity. We will look at four classes of environmental hazards: Cultural‚ Biological‚ Physical and Chemical (Wright & Boorse‚ 2011)

objective of this experiment is to differentiate between a physical change and a chemical change. A physical change includes a change in the material without affecting its composition‚ such as the physical state change. However‚ a chemical change includes the change in the composition of the substance. The change in color‚ formation of a gas or a solid product‚ and the production of energy are the evidences of a chemical reaction‚ thus‚ of a chemical change. Materials Crucible tongs Evaporating
