Determine the individual Hazard Quotients and the overall Hazard Index associated with a 70 kg adult eating 15 g fish every day that contains 9.8 μg/ kg of Arochlor 1254 and 1 mg/kg of Methylmercury? Arochlor 1254 can exhibit noncarcinogenic effects in humans. Methylmercury has been shown to cause developmental neuropsychological impairment in human beings. The RfD for methylmercury is 1x10-4 mg/kg-day and the RfD for Arochlor 1254 is 2 x 10-5. Also, comment on the risk involved, based on the individual Hazard Quotients.

Landfills

The landfill is a site used for the disposal of waste materials. The landfill is a solid waste facility that is often known as a dumping ground. The image below shows a landfill site in Hawaii. Landfilling is the most ancient and common method used for the disposal of waste. For the landfill, a deep trench is constructed in an isolated place away from the city. The trench for landfills is designed properly after analyzing the total population and the waste generation per capita. The waste is dumped into the trench and after every layer of waste, a layer of soil is spread on the top of it.
