If pregnant woman eat a large amount of contaminated fish from the Hudson River their children are more likely to be born with birth defects. These contaminants are also known to cause damage to the nervous system, immune system, and the reproductive system. PCB’s can also cause a specific type of cancer. In 1983 they delcared the Hudson River a Superfund. It has ben turned into one of the nations largest Superfund Sites.
Environmental Hazards a. In the St. Lawrence River, lots of industry has resulted in high levels of toxic chemical such as polychlorinated biphenyls (PCBs) and dichlorodiphenyltrichloroethane (DDT) and heavy metals. b. Because these toxins affect not only one specie but also all of species that are interconnected by food chain. c. These pollution decline beluga’s immune system, get disease easily that linked to low birth rates of belugas which have lived in the St. Lawrence River.
* Toxic exposure- poisonous chemicals and gases, such as carbon monoxide poisoning. Outcome 2 Understand the impact of an acquired brain injury on the individual 1. List initial effects
Risk Assessment of Malathion The city of Genericville faces a huge dilemma with a potential West Nile Virus scare. The river that runs along our exceptional city has several wetlands that protect our city during the spring from flooding; in addition it also provides a source of nutrients to birds and fish species found only in this area, which in reattribute contributes to why Genericville is a popular tourist summer distention. The unfortunate downfall to the wetlands is that it also serves as a reproduction ground for mosquitoes; hence the West Nile Virus scares. This virus primarily spread through the bite of an infected mosquito; animals and humans alike are both at risk. The Center for Disease Control states that the West
Legislation in the laboratory Risk Assessment for screaming jelly babies | Substances that is a hazard towards health: | Jelly babies are a procedure of sugar, glucose syrup, water, gelatine, citric acid, flavourings, and colours.It also contains another substance : Potassium chlorate (V) | Regulations: | Oxidising and harmful – This is explosive when it is mixed with other reactive materials or substances. It is also harmful if inhaled and if it swallowed by an individual. | Risks and precautions | Potassium chlorate - Majority of the explosives have been due to mixing chlorate with flammable materials, this can lead to explosions if more than enough quantity and powerful enough heating is involved.Potassium chlorate with sugar – If there are mixture with sucrose ignites more than 159oc that has
Although it cannot be ruled out completely, the child becoming ill from toxins passed in the mother’s breast milk is a less likely scenario than the child becoming ill as a result of exposure to toxins brought home by the mother on her clothes or other articles (Natural Resources Defense Council, 2005). There are numerous articles and reports stating that although contaminants are commonly passed from mother to child during breastfeeding, levels high enough to cause toxic exposure are rare, and the negative effects of the contaminants present in
Mercury is the principle agent that kills contaminants. The department of defense states mercury is very hazardous and can cause death if swallowed, inhaled or absorbed through the skin. Mercury poisoning has caused dyslexia, hyperactivity, seizures, autism, mental retardation, speech delays and attention deficit disorder. Mercury can be found in dental fillings, many vaccines, and certain fish contaminated by polluted oceans. Immunizations weaken the immune system and makes it work less efficiently.. Immunizations have harmful chemicals in them that are dangerous to the body.
Each of these compounds is known to be poisonous, cancerous, or cause birth defects. The EPA fears that the drinking water will compromised due to runoff of the surface water discharge. Additionally, contamination of underground sources of drinking water and inadequate treatment of the waste water are possible. The threat of contaminated water supplies can cause a fearful population, largely due to the propaganda spread by anti-fracking initiatives. Although there are potential economical disadvantages to fracking, there are also enormous positives.
The type of pesticide that can affect our environment and health are the chemical pesticides. Even though it has been proven dangerous by scientists the government still allows the use of harmful chemicals on many of the foods we eat. The full health risks associated with pesticides are unknown and most pesticides have never been thoroughly studied for their possible long-term health effects on humans. Everyday humans, plants and animals are exposed to a number of different pesticides, which are harmful to their health. Constant exposure can seriously endanger their physical and mental health.
Spatial, vertical and temporal variations of elemental mercury and human exposure to deadly effects of methyl-mercury are also presented in this study. Ishan Joshi 2 1. Introduction: Mercury occurs naturally in the Earth’s biochemical system. It is a highly volatile trace metal. Before an industrial
