Summary
Human Toxic Chemical Hazard i. Indentifying toxic chemical substance Aflatoxins are types of mycotoxins produced by a type of fungus called the Aspergillus flavus. Aflatoxins are toxic chemicals that are harmful to the human body. This chemical substance occurs in form of molds that grows in legumes, seeds and nuts (Smith, 26)…

However, according to Consumer Product Safety Commission (CPSC), fungi produced mycotoxins are harmless and helpful to human body. In addition, according to Food and Drug Administration (FDA), Aflatoxins are not harmful if only consumed in very minute quantities. This toxic chemical substance is known to cause acute liver damage and liver cancer (Smith, 33). The cumulative effect of this toxic chemical substance is what is known to cause the liver diseases and damage. A major concern about this toxin is that it is heat stable. Thus, once produced on food substances such as vegetables, seeds, legumes and nuts, they remain permanently, since no extreme temperatures can destroy the toxins. Any heating or freezing has no impact on the toxic chemical substance (Huddler, 8). ii. ...
Is this an Acute and/or Chronic threat? The chemical poisoning caused by the consumption of food substances invade by this toxin is acute. Is this a Systemic and/or Target Organ Threat? The poisoning caused by this toxin is both target organ and systematic. The intoxication is target organ since it affects the liver, causing its damage and causing other liver diseases such as liver cirrhosis, hepatic fibrosis and fatty liver disease (Abash, 125). The intoxication is also systematic since it causes a variety of different cancers on the body, affecting different body parts. The poisoning caused by the toxin can also cause the blockage of small arteries, due to blood clots (Bingham, 591). Most important, the infection is systematic since the intoxication causes the malfunction of the digestion system. This affects the absorption of nutrients by the body, subsequently affecting the stability of the brain and eventually leading to coma and death. What Are The More Likely (Probable) – Additional, Concurrent Chemical Exposures That May Interact With The Selected Chemical? The Aflatoxins have a probability of interacting with the alkaline substances of the human DNA, thus causing gene mutation. What Type of Chemical Interactions May Occur With the Additional, Concurrent Toxic Chemicals? The type of chemical reaction likely to 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 ...Download file to see next pagesRead More

Ecosystem toxic chemical threat
...? 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...

...number of ways. The level of harmful threat of heavy metals to the environment and to aquatic life depends on the amount of exposure. To contain these hazardous effects, first, the governmental bodies concerned with the environment, such as environmental agencies, should implement more strict policies to lessen entry of toxic chemical or heavy metals into marine environment from the industries. This can be done through assessing and determining the heavy metal concentrations of the effluents or discharges from the industries to the sea or marine environment (Palmer 113). Besides, we can encourage the use of alternative eco-friendly organic manure instead of inorganic...

...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 additives are used for...

... is found in the earth’s stratosphere. On the other hand, bad ozone is the air pollutant, and forms a layer closer to the earth’s surface. The bad Ozone is composed of exhaust fumes from automobile, emissions from industries, and chemical solvents, among others. This layer resembles smog covering most cities in the U.S.A. Particulate matter comprises both tiny solid and liquid particles in the air. These can be metallic, soil, or dust particles and particles, which are acidic in nature. These particles are inhalable by humans, and settle in the lungs. On the other hand, Carbon Monoxide is a toxic gas emitted from automobiles and combustion process.

...Risk Assessment by Identification of Hazard Introduction Falls, one of the most frequent cause of fracture and death among the elderly, is considered as costly in terms of both suffering and utilization of services. Nandy, et al. (2004) stated that amongst the elderly residing in a community, it was noted that no easy applied and validated tool is yet made available. At least 40% of all hospital accidents are caused by falls, and the risk of acquiring hip fracture secondary to fall is eleven times higher in the hospital setting compared to cases in the community setting (Papaioannou et al., 2004). History of previous fall, difficulty of transferring or ambulating the...

Conclusion Response mission success in the case of a gas leak incidence will depend on proper use and integration of the various principles of the incident command system. Therefore, the management of various institutions should train their employees on how to use the principles of the incident command system in the management of such kind of disasters.
