The nervous system is the most sufferer organ being principal target of number of metals. The alkyl derivatives of certain metals such as lead, mercury and tin are specially neuro-toxic.22 The symptoms associated with acute lead exposure often involves rapid onset of nausea, headaches, cognitive changes, and emotional disruptions. In chronic exposure, fatigue, decreased processing speed, fine and gross motor deficits, and generally decreased cognitive functioning, neuro-degeneration and psychiatric manifestations like increased depression, anxiety, and irritability are more prevalent.23 It has been observed that immature organisms are particularly susceptible to the adverse neurological effects of chronic lead exposure. As compared to adults, …show more content…
Lead is having profound effect on calcium metabolism and transport which inhibit the release of acetylcholine. Moreover Lead is well known to disrupt heme synthesis. The loss of heme containing enzymes is associated with mitochondrial function producing adverse effects on energy metabolism. Lead may affect neurotransmission by interference with neurotransmitters. In fact, aminolevulinic acid, produced as a result of lead action on heme synthesis, has a similar chemical structure to γ-amino-isobutyric acid. Action on the GABA system might produce signs of neurotoxicity similar to those seen in severe lead …show more content…
In addition, lead produces renal neoplasms, interstitial fibrosis and progressive nephron loss, azotaemia and renal failure. Chronic lead exposure is also implicated in the development of saturnine gout and hypertension. The metal interacts with renal membranes and enzymes and disrupts energy production, calcium metabolism, glucose homeostasis, ion transport processes and the renin-angiotensin system. 32,29 Effect of lead on reproductive system: Infertility is a reproductive health problem worldwide which affects many couples especially in developing countries. Lead is ubiquitous and persistent heavy metal which has detrimental effects on almost all the major organs.33 Male and female reproductive systems are one of the major target sites of lead induced toxicities.34 Effect on Male reproductive

Most damages when exposed to teratogens occur during the embryonic period. Lead exposure during the embryonic period can cause stillbirths, increased risk for malformations, and VACTERL syndrome; VACTERL association is a disorder that affects
Other guidelines were exceedances were observed are the BC’s working sediment Guidelines and the contaminated sites regulation sediment quality criteria. An excess level of selenium, which is taken into the body in water and foods, can cause significant side effects like nausea, vomiting, nail changes, irritability in the nose and throat (producing coughing, nosebleeds, dyspnea, bronchial spasms and chemical pneumonia). Exposure to lower levels of Arsenic in the short term can cause nausea and vomiting, swelling and redness of the skin, decreased production of red and white blood cells, abnormal heart rhythm, damage to blood vessels and a sensation of “pins and needles” in hands and feet.
Recent studies have shown that the water in Flint, Michigan has been contaminated by a horrible health impact, lead. This has happened because nearly two years ago, the state of Michigan decided to save money by switching Flint’s water supply from Lake Huron, to the Flint River a notorious tributary that runs through town known to locals for its filth. This has led to many terrible effects shown in both children and adults. The many effects lead has on children and adults are very drastic if not taken care of properly they could have lifetime effects. Dangerous effects lead can lead to that effect children.
Residents started to report that they were experiencing rapid hair loss, chronic migraines and blurry vision.

They argue that since only the wealthy could afford to have lead pipes bring water into their homes and to cook with lead utensils, their death rate was increased considerably” (Doc 7.8). One death cause of the Romans was lead poisoning. Many Romans died from this, which led to the fall of the Western Roman Empire. According to Document 6, nearby barbarians, the Huns, the Visigoths, the Franks, the Anglo-Saxons, the Vandals, and the Northmen,
In this experiment we tested to see if the catfish contained lead by using a lead testing kit. We used the data collected by ORNL in 2011 that is now accessible to the public. We pose that, if the age of the lake is older than the amount of lead will increase in the catfish when the amount of lead in the fish is a function of how old the lake is. Assuming the age of the lake would affect the amount of lead in the fish. The lakes that we picked were Tellico Lake, Melton Hill Lake, Watts Bar Lake, and Fort Loudon Lake.
Ryan Hogan OT-525 9-21-15 While taking the health risk assessment I knew right from the start that some of the information would be off. The assessment asked about things such as blood pressure and cholesterol, and I do not know these measures right of the top of my head. While looking at the results, it stated that I am at risk of dying within the next 10 years. When comparing my risk percentages to the average 27 year old male, I did very well and was average compared to the others. However one factor that I scored above average on was the chance of a heart attack.

The Earth has been creating many amazing things for centuries which can be found all over the world and has many parks dedicated to these amazing landmarks. These parks can just be normal parks with amazing views or just being a serene place to relax. Some parks however can be seen as being human made and can be just as fascinating as the ones that are natural. While these things can be similar they can also be very different to this will be the focus of this essay and how they can be similar or just different. Each paragraph is focused on a compare and contrast of each subject which is Normal natural parks versus The Newark Earthworks.

Review of Literature Environmental issues began to be discussed and debated only towards the end of the 20th century. Since then significant amount of literature has been penned down raising awareness about issues of pollution, deforestation, animal rights and several others however it has failed to result in major changes, ideas or even actions to save the environment. Several species of animals have become extinct; pollution level is at an all-time high, global warming is leading to severe climate changes all across the globe but these problems do not seem to alarm the decision makers. Leydier & Martin (2013) also states that, “despite the increasing expression of concern in political and media debates about issues such as climate change, pollution and threats to biodiversity, “political ecology” (operating at the confluence of scientific developments, political engagement and ethical debates) is still trying to find its bearings” (p.7). It is quite evident that environmental issues are not treated in equivalence to political, economic, social or even religious issues.
