According to the Environmental Protection Agency (EPA), vehicle exhaust fumes have been confirmed to contain carcinogens; a statement that is further confirmed by the World health Organization (WHO) which said that the fumes expelled by diesel vehicles contain a harmful amount of carcinogens that may harm people who take them in through breathing. The National Institute of Health (NIH) and the Centers for Disease Control (CDC) back up this information by confirmation of the information stated above (Thakur and Haru 64). From the website, the toll of exhaust fumes to the environment is high since they affect a wide range of the components of the environment from human beings, animals and the environment in general. With components such as lead and sulfur emissions, there are many detrimental effects of exhaust fumes to the environment (Monosson 44). From the class notes and the course being undertaken, it has been proven that vehicle exhaust emissions form a large part of the green house gases that are responsible for the increase in the temperature of the earth in what is called global warming. While there is information from many sources against the high amounts of vehicle exhaust gases and fumes and their contribution to global warming in general, the website has an argument that depicts vehicle fumes as only having little effect on the environment compared to the other sources of pollution like industries. The author of this article argues that it is not right to put blame on vehicle exhaust fumes as the main cause of global warming when it is this area that had had the most improvement in terms of eliminating the negative impacts to the environment (Barrow 71). It is thus a great topic to choose upon given that is has a lot of information and topics for discussion. Section Two: Vulnerability of the Environment to Vehicle Fumes The impact of vehicle exhaust fumes is majorly chronic in its impact on the environment. Since the impact of many polluting elements is chronic to the environment, those of exhaust fumes follow the same path and have the same impact. This is due to the reason that it takes some time for the chemical elements in the fumes, which are mostly little in amount, to accumulate to harmful levels and thus affect the environment (Jones 86). The threat from vehicle exhaust fumes is also systemic (ecosystem) in nature given the fact that it affects the environment as a whole. The elements released by vehicles and the gases that accompany them add up to cause not only diseases in animals and human beings but also cause global warming that affects the whole ecosystem (Gupta 45). No specific species is targeted by the negative effects of these chemicals since they affect all the living species from plants to animals in equal measure. Section Three: Risk Assessment The risk level from exhaust fumes is very real given that each day; a very large amount of fumes is released by vehicles all over the world. The number of vehicles owned especially by private individuals increases every single day given that more and more people are affording to buy vehicles for their personal use and other purposes. Even with efforts that are ...Download file to see next pagesRead More

...? ECOSYSTEM TOXIC CHEMICAL THREAT The environment has been exposed to numerous harmful substances due to human activities. Chemical threats often occur by either deliberate exposure of poisonous materials or through accident. These poisonous materials are extremely harmful to humans, animals as well as vegetation. They are released from oil leakages, industrial emissions, motor vehicles among other sources. The emission of dioxins is viewed as a main environmental impact of the combustion process. This paper identifies dioxins as toxic compounds and shows the physical and chemical properties of dioxins and impact of dioxin emissions on public health and...

Human Toxic Chemical Hazard And Risk Assessment occur is intercalation and alkylation of the DNA molecules. iii. Risk assessment This toxic chemical substance cause harm to consumers on the event that they consume food substances, which has this toxic substance in them. The toxin can contaminate the food substance before harvest and during storage (Smith, 27). The vulnerability of the food substance to this toxin is when they are exposed to highly humid conditions or when they are damaged by conditions such as drought or other conditions that lowers the barriers to entry of the toxin on the food substances. The toxin is mostly harbored in soil, decaying vegetation and in grains that are in the process of...

...Ecosystem Toxic Chemical Threat SECTION ONE Toxic heavy metals I have chosen on this topic based on the information released by Environmental Protection Agency (EPA) in their previous year 2011 annual meeting, that the contamination or pollution of clean water with a broad variety of pollutants, such as heavy metals, has reached a matter of a global concern for last the few years. By definition, heavy metals have a density of 5.0/gcm3 or more which is much heavier than the density of an average soil particle. They occur naturally in rocks but their concentrations are regularly augmented due to contamination and pollution. The most common heavy metals with respect to...

.... Some articles in the website even said that the government and environmental organizations only publicize an apparent human-made global warming to get more funding (“Great Global Warming: News and Truth about Global Warming”). Section Two: Address the vulnerability of the environment - ecosystem to the specific Chemical Threat 1. Is this an acute or chronic environmental threat? Greenhouse gases are chronic environmental threat. They have been present in the atmosphere possibly even before life existence. In fact, carbon dioxide is needed by plants to produce food and release oxygen. However, its environmental effects have currently been manifesting because of its...

...Human Toxic Threat Risk Assessment Threat Selection Most of the manufactured foods and drinks contain additives either meant to preserve them longer than they would last in their natural form or to alter the way they taste. According to the Agency for Toxic Substances and Disease Registry (ATSDR), many of the additives used are harmful to the consumers’ health. An example given by ATSDR is diacetyl which is used to flavor butter and causes constrictive bronchitis. The Centers for Disease Control & Prevention (CDC) also backs up this with evidence that diacetyl and other food additives have adverse health effects (Barrow 77). Food...

...adverse effects depending on the type of pollutant they are exposed to (Dickey, 2009). Air pollution is both a chronic and acute chemical threat. This is because it is an amalgamation of various toxic chemicals in the air. Some effects of bad ozone on human health are considered chronic. This leads to different types of chronic respiratory diseases, including asthma. On the other hand, particulate matter has acute effects on health. This leads to restricted activity, which makes one to lose work or school days because of respiratory illnesses. One might also experience asthma exacerbations, bronchitis, and chronic cough among others. However, people more vulnerable to acute illnesses because of air...

Threat Assessment & Physical Security all times. This way the head of security can manage to be on top of every situation. (Diligence Intelligence and Risk Management, 2007) After the hearing, before embarking on the trip back the principal’s residence, have the security officers stationed give clearance to signal that it is safe for the principal to come home. Once on the road, be cautious of the possibility that some groups may try to attack while the principal is in transit. Be ready with contingency plans. References AT&L Knowledge Sharing System.

Threat and Risk Assessments
...Threats and Risk Assessment Law enforcement agencies or the police services, as commonly known in countries outside North America,have a responsibility of developing a proper framework of dealing with threats and corresponding risks. This kind of framework can be achieved through Threats and Risk Assessment, which primarily focus on jurisdictional determination of the ability to respond to technological and natural disaster through identification, prioritization and assessment of threats that are caused by different criminals or crime groups (Ratcliffe, 2009). However, it is of great essence to establish a universal body that puts into consideration the diversity in agencies, jurisdiction and countries, however, how difficult... it is....
