(1) Discuss the Aum Shinrikyo attack. What made the attack successful? Why were the casualties relatively low? March 20, 1995 a major subway line in Tokyo, Japan was attacked by the Aum Shinrikyo cult.…
Part A Me Text Statement A A 1. If UV intensity levels doubled, mutations in animal cells, skin cancers, and cataracts would increase. “The intensity of UV radiation reaching the Earth’s surface doubled—levels that would increase DNA mutations in human and animal cells, suppress our immune systems, and increase the incidence of cataracts and skin cancer.”…
It has been complicating issue what the US government approach regarding the use of plastic material. In case study revealed Lake Apopka, Florida’s third largest lake encountered a chemical spill in 1980 abolishing alligator population and other agricultural affect with endocrine disrupters. The function of plastic provides utilization in our day to day life. Products manufacture creates flexible material cause to exist it in our society though convenient in our day to day use. Plastic contribute our society in unique meaning in a number of improvement in technology development including advancements in satellites, shuttles, aircraft, and missiles.…
Effects: When inhaled, Chlorine reacts with the water in the lungs and creates hydrochloric acid. It causes (in low concentrations) coughing, vomiting and eye irritation. Chlorine is lethal in high concentration and causes a rapid death. First Used: Chlorine was first used by the German army at Ypres in 1915.…
Ingesting these contaminants can lead to serious health…
Canadians are exposed to goods and services, which depend on the use or release compounds, which may have negative effects to human health and to the environment. While some of the substances are broken down in the environment over some time, others linger for a long time, with expensive implications. Hence, it is important to handle risks related to toxic substances, to avoid effects, which could be costly or rather impossible to manage in the future. Since, science experts today cannot predict the risks of toxic substances on human health and environment, it is best to utilize a proactive approach by preventing pollution. Policies are therefore important tools for managing the problem of toxic substances in Canada (Scott, 2009).…
The calculated free chlorine concentration of the St. Lawrence University pool water was 0.6867 mg/L, which was determined using absorbance spectroscopy. A stock solution of free chlorine solution was used at various volumes, and was diluted by water in a volumetric flask. Then DPD free chlorine powder pillows were added to each, and their absorbance was measured using a visible absorption spectrometer. The concentrations and absorbance of these four solutions were then used to create a graph to formulate the standard curve based upon Beer’s Law. The pool water sample followed the same steps as the previous solutions and absorbance was plugged into the standard curve.…
Water pollution is a global threat to the environment, ecosystems and the well-being of humans. Pollution is the introduction of any unnatural substances into the natural environment such as pesticides, plastics, and oil spills. Although Canada has made significant improvements, there are still water pollution issues that need to be solved and addressed. Pesticides are one of the many pollutants that enter water bodies that impose a threat to humans and ecosystems.…
According to Joseph et al. (2000), perchlorate has been lately identified as a persistent and pervasive contaminant of drinking water substances in some of metropolitan regions. Perchlorate is stable beneath normal atmospheric conditions and particularly soluble in water. When a perchlorate compound is released into the environment, it will dissolve in water, and because of its capability to adsorb directly to surfaces, it will be transported thru bulk movement of water and mixing processes (Srinivasan & Viraraghavan, 2009). When the flow is much less or if water turns into stagnant, perchlorate has a tendency to diffuse into clay layers in an aquifer.…
Authors can influence their readers to do something useful for the environment with several different types of writing. There are three main types of influencing ways a author can write. One would be a way of protesting to change something. Another way would be showing how people what other people are doing to inspire them to do the same. The last way would be to right a fictional piece and represent what is going on in the environment.…
Fighting Back Against Water Pollution Water pollution needs to be reviewed as the increase in toxins in possible drinking water has increased in the last 20 years. Through the use of our technology and use alternative renewable energy sources, re-evaluating our usage and methods of disposing waste preserving both fresh and marine water in the United States. A common discrepancy that is brought up when discussing water pollution is whether the cost will become too large to even begin creating change, that the amount of resources required to implement could be used elsewhere for a more immediate impact. The discussion of environmental problems is a topic of many political debates, but throughout the years scientific evidence has documented the…
Pesticides, a substance used for destroying organisms that are harmful to cultivated plants, are extremely damaging to the environment, and can be detrimental to human health. Pesticides are typically used on farms, and over 1 billion tons of pesticides are used each year. Pesticides can lead to air pollution, after pesticides are sprayed on plants, winds can pick up the chemicals, leading the chemicals to remain in the air, which can potentially harm wildlife. A solution suggested that opposes the harmful chemicals is the use electromagnetic waves to repel small rodents. These electromagnetic devices claim to affect the nervous system of small rodents, which allows them to stay away from said area.…
MNC or Multi National Corporations have branches in other countries and the head office , which is centralised and coordinates global management, is usually located in the home country the company was founded. Some characteristics that MNCs include will be that it involves a large scale of business , Productive organization, ability to transfer technology and evolves in high efficiency. Examples of MNCs include Nike,Cotton on, Mac Donalds & Apple. LDC stands for Less Developed Countries . LDC is mainly identified as Lacking in terms of economy, infrastructure & industry.…
These contaminates disturb the ecosystem, cause human illness and is said to be the cause of global warming. Pollutions occur from smoke from vehicles, chemicals in the soil due to humans, dump wastes into rivers and many other reasons. Many people do not know, but surprisingly technology is another reason…
CHAPTER I INTRODUCTION 1.1 BACKGROUND STUDY Wastewater in the textile , plastic, paper and cosmetics industry is a major threat to the environment. The volume of wastewater produced starts from different processes throughout from the pretreatments to the final treatment. The contents found in the wastewater are complex, having inorganic and organic compound chemicals in it and aquatic lives are at risk. Some of these wastes have even caused mutation in genetic coding of the marine organisms(Gao, Qin et al. 2013) .The…
