Risk Management - Movie Review Example The incident not only caused problems for the rivers and inlets near the Tisza, but also to larger bodies of water connected to it, such as the Danube River and the Black Sea. The chemical spill was pinned onto an Australian-owned mining company using cyanide salts for mining gold and silver, which is an outlawed method in Europe. But the company denied all allegations, and even attributed the chemical spill and the river’s death on environmental factors (Harper, 2005). The spill had a lasting effect on the water supply, but despite having no record of human health impacts were recorded, it greatly affected the wildlife that lived on the river and the residents that depended on it for food and livelihood (Marmorat, 2008). While the early March floods that occurred after the chemical spill were able to lessen the impact due to the dispersion of the chemical and heavy-metal contaminants, it was estimated that it would take at least a decade to see any improvements in the riverâ €™s state. The following are the assumptions on the possible causes and effects of the chemical spill to wildlife and the residents living near the Tisza River and its basins: Precipitations might have possibly caused the toxic sludge containing both cyanide and other heavy metals to overspill the dams holding them in and caused the excesses to flow into the nearest bodies of water. The cyanide content of the toxic sludge that flowed into the bodies of water and ended up into the Tisza River might have been too high, that the effects of the poison lasted months and even years after the chemical spill. The toxicity levels of the sludge affected the livelihoods of the fishermen that depended on the River Tisza by rendering all kinds of fish either dead or too highly- contaminated to be consumed, thus any kind of commercial fishing would be counter-productive. Due to the numerous waterways and other areas where the Tisza River drains its water, not only did the chemical spill affec t other larger rivers, but also the smaller ones where these large rivers either enter or exit into, causing damage to greater areas. Because the interconnecting rivers and channels affected by the chemical spill run into countries outside Romania, the environmental disaster could cause political unrest between the countries whose rivers were affected by the chemical spill, and Romania. 2. Review and attach an MSDS for Cyanide The following MSDS has been condensed from the Science Lab (2005) data sheet for their sodium cyanide product, which is the form of the cyanide salt normally used for mining: Section 1. Chemical Product Chemical Name: Sodium cyanide Chemical Formula: NaCN Section 2. Composition and Information on Ingredients Composition (by Weight): Sodium cyanide = 100% Toxicological data: Sodium cyanide Oral (LD50): acute: 6.44mg/kg (Rat) Dermal (LD50): acute: 10.4mg/kg (Rabbit) Section 3: Hazards Identification Potential Acute Health Effects: Very hazardous when ingested or inhaled, or when in contact with the skin or eyes. Damaging effects to exposed tissues are proportional to length of contact. Potential Chronic Health Effects: Repeated or prolonged exposure can cause damage to the nervous system, tears and lesions in the skin and lungs, leading to asphyxiation. Section 4. First Aid Measures After doing the following first aid measures, seek medical help immediately. In case of eye contact, flush eyes with water for at least 15 minutes. Remove contact lenses first, if present. In case of skin contact,
