The environmental impacts of coal, oil, natural gas, biomass, hydroelectric, nuclear, solar, wind, and hydrogen in Canada

What are the direct and indirect environmental impacts of coal, oil, natural gas, biomass, hydroelectric, nuclear, solar, wind, and hydrogen usage in Canada?

Translating quantitative evidence into a written account.

Emergency Plan For a Agricultural Warehouse fire

I am currently doing a Toxicology assignment and was hoping that someone could shed light on how different organization would attack this particular incident. The situation involves a chemical fire near a small town. I am contacting you because I am hoping to utilize your professional skills. The assignment is as follows. THE PROBLEM: There has been a warehouse fire and the warehouse, located in rural area, contained 6 million kg of agricultural chemicals. The warehouse had a "secret" floor drain that was piped with a 20 cm pipe to small lagoon. The lagoon is located so that the overflow water from the lagoon conveniently flows to the highway ditch and that slopes down for 0.8 km to a... click for more

A lagoon with volume 1200m^3 has been receiving a steady flow of a conservative waste at a rate of 100 m^3 per day for a long enough time to assume that steady-state conditions apply. The waste entering the lagoon has a concentration of 10mg/L. Assuming completely mixed conditions, a. what would be the concentration of the pollutant in the effluent leaving the lagoon? b. if the input waste concentration suddenly increased to 100mg/L, what would be the concentration 7 days later? c. Repeat this problem for a non-conservative pollutant with a reaction rate of K=0.20/d

An electric water heater held at 140 degrees F is kept in a 70 degree F room. When purchased, its insulation is equivalent to R 5. An owner puts 25-ft^2 blanket on the water heater, raising its total R value to 15. Assuming 100% conversion of electricity into heated water, how much energy (kWhr) will be saved each year? if electricity costs 8.0 cents/ kWhr, how much money will be saved in energy each year? I believe its q=A(T2-T1)/R, but don't know the area One day, you are out hiking and find a beautiful river where you want to go fishing. The river is flowing at 1.5m/s. Next to the river, there is an abandoned mine leaching copper in the river at a concentration of 14mg/L. Co... click for more
