EFFECTS OF VOLATILE ORGANIC COMPOUNDS (10244818) Volatile organic compounds (VOCs) are organic chemical compounds that have high enough vapor pressures under normal conditions to significantly vaporize and enter the atmosphere. According to EPA ’s Terms of the Environment‚ a volatile organic compound is "any organic compound that participates in atmospheric photochemical reactions except those designated by EPA as having negligible photochemical reactivity." VOC can also stand for the term “volatile

especially vulnerable to unhealthy levels of air pollution. There are many kinds of air pollution. The ones I want to talk about are the ozone‚ acid rain‚ carbon monoxide and toxic air contaminants. Ozone is formed when hydrocarbons and nitrogen oxide react in sunlight. Therefore‚ ozone is at its peak during hot summer days. Exposure to high levels of ozone can have serious consequences on your health. It can cause respiratory disease‚ loss of pulmonary elasticity‚ and premature aging of our

buildings in its place making it impossible for anything to grow there. Those trees were a crucial part to the ecosystem and environment‚ which are now changed forever. We also drive cars‚ which emit exhaust‚ which in turn hurts our ozone layer and heats up the Earth. Once the ozone layer is damaged the ice caps melt a little and now the entire environment is changed‚ all thanks to man. Not to mention that biomes are changed as well due to global warming; the ice caps melt a little and the world gets hotter

What causes a volcanic eruption? When a part of the earth’s upper mantle or lower crust melts‚ magma forms. A volcano is essentially an opening or a vent through which this magma and the dissolved gases it contains are discharged. Although there are several factors triggering a volcanic eruption‚ three predominate: the buoyancy of the magma‚ the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber. What follows is a brief description

Ecologically‚ Economically & Globally Automobiles have transformed our planet. There are positive and negative outcomes in all new technological innovations‚ new to the world products‚ and within product line extensions. Automobiles have a severe impact on society’s daily needs of transportation‚ their profit margin capabilities for corporations‚ and seemingly cover our globe. Considering these standards‚ innovators tend to shy away from implementing modernism of transportation. There are simple

This study was also done to test the effects of beliefs about self control on subsequent performance in self control tasks. Participants’ performance on the Stroop task and phonemic fluency task and subjective feelings of tiredness were assessed before and after an ego depletion task‚ one group was primed to believe that self control

This photochemical smog is actually generated‚ “When [components from primary] pollutants like hydrocarbons and nitrogen oxides combine in the presence of sunlight” (Types of Air Pollution‚ 2010). Plant and animal life can be damaged by ozone smog. With the PAN‚ photosynthetic efficiency reduction and plant growth occurs because of

Humans must take action to resolve them. This is because the world cannot exist without water. Every living thing depends on water and would not survive without it. Of all the water resource problems‚ one of the most important to solve would be the depletion of aquifer supplies. An aquifer is the body of sand that is able to store or produce large amounts of water. They can be anywhere from a few feet deep to a few hundred feet deep. From a bird’s eye view an aquifer can spread as far as a few hundred
