Toxic cocktail anyone?

Figure 1. Toxic compound sign. Get used to seeing it

On principle, I don’t typically have issues with what people tend to do with the piece of property that they legally own. But, like most people, I draw a fine line and voice my opinion when Jiminy Cricket pipes up. The topic of today’s issue revolves around the recently proposed, yet not operational, Ajax Mine. For everyone reading this who may not be in Conservation Biology 4160, the Ajax Mine is to be a copper and gold, open-pit mine that is to be 2500 hectares large (Ghaffari, 2012). You may be thinking “Oh that’s economically beneficial and kudos for supplying those jobs during an economic catastrophy”, but at what cost are we supplying these jobs? The Ajax Mine is to be located on top of the Iron Mask pre-existing mine site a mere 1.75 km from the nearest existing residential homes (Young, 2011). Not only does the reintroduction of a mine mean direct habitat loss, noise complications with closely located residents, the potential extirpation of threatened species, and expected dust showers daily. But also the toxic side effects to not only us, but the animals and plant life that will be coexisting with us.

In 1993 a geological minerals composition survey was performed on many location spots in the Kamloops area (Snyder and Russell, 1993). Jacko Lake Area and Iron Mask Area were both positive for containing an element NiO; Nickel(II) Oxide. Typically what is done is that the nickel oxide is dug up and then is heated with either carbon or carbon monoxide or hydrogen yielding it to a metallic nickel. The not so fun part occurs when NiO is not transformed after is it dug up and before it is blown into the surrounding air. The side effects of long term exposure, say 23 years, to NiO includes damage to the lungs, resulting in lesions and in severe cases cancer (Coogan, TP et al, 1989). Studies have shown that both humans and animals alike are effected negatively to nickel. Also, Cr2O3, a trivalent chromium was found in the mineral composition. This elements is absorbed poorly by inhalation and intact skin contact. But, if this compound were to enter into your systemic circulation toxic effects may develop. Personally something I wouldn’t choose to risk. MgO, Magnesium oxide, was present as well. This mineral is termed “slightly hazardous” because it causes skin irritation and eye irritation. It is also hazardous if inhaled or ingested. Patients who overdoes on magnesium oxide are to seek emergency medical attention due to syptoms of nausea, vomiting, flushing, low blood pressure, low heartbeat, drowsiness, coma and DEATH (drugs.com). The toxins mentioned here only scrape the surface of what may harm us. There is a whole other ball field for the toxins that may seep into our water supply, but that is for another day.

So I will leave you blog follows with this thought provoking question:
Is it not better to consider the worse before it has happened so that we can consider all options and opportunities to compensate for the it; than to just “hope for the best” and deal with the worst when it has come? Preventative measures are surely lost and meaningless when preparation is not expressed or even considered.

  1. Very interesting. I enjoyed how you went more into detail about the toxins and how they normally would reduce our risk to them. It is also good information to note all of the effects of them! Sure doesnt sound fun to have any of those symptoms.
    And for an answer to your question...I think I would rather be safe then sorry and consider all of the options and opportunities.
    Enjoyed your blog!

  2. I also talked about air pollution measures and how these will not be effective and that Kamloops air pollution can increase as much as 30%. This along with the minerals that you have talked about is extremely scary. I agree with you in that the mine isn't worth the obs when you have to take into account other peoples health and the health of the ecosystem as well
    Really enjoyed your blog, very well done!

  3. WOW !!! That doesn't sound like too much fun.. I did really like hearing about all of the potential toxins and risks that are associated with the area in question. I think that your blog was really well written and needed to be said! As for the toxins that would be detrimental to the health of people and animals: did you read about how far the air borne ones will travel?? or how much it will take to see the effects??

    1. I'm sorry I can't give you a definite answer to your questions. All the answers are "It depends". It depends on how windy it is, where the wind blows, how much of those elements are dug up, and at what rate, as well as how long each individual is exposed to the elements, and the strength of the individuals immune system with regards to ridding the body of toxins.

  4. This worries me. There are so many potentially dangerous effects that could arise from this mine. It is hard to predict what could go wrong, so I agree that I would rather be safe than sorry!

  5. And don't oxides react with water to create acid rain? Though Kamloops is pretty dry, I would imagine that any amount of acid rain would negetively impact the water quality and plant species of an area. As I mentioned in another blog, I think it is also important to think about species that are extremely sensitive to air quality, like the birds. On the cynical side, though, maybe the health care system of Kamloops would experience an economic boost, with all the new lung cancer patients... :(

  6. Very interesting blog, I was not aware of all the health side-affects caused by long-term exposure to NiO, Cr2O3, and MgO. Wow...and people still wonder why cancer is so prevalent in our society! One of the main causes I feel fit, is due to the large amounts of industry. It seems that industrustrial developments and operations don't take the health-care of the citizens into as much consideration as they should and their practices cause huge amounts of pollution and environmental contamination. If they do take health into consideration it seems that it's only because they have to when following "proper legislation." When it comes down to it at the end of the day I feel they are more interested in making money for the time being or for the owners/investors in the coorporations then they are about the healthcare of the citizens or future generations. Do you guys think they would even take our healthcare into consideration if they didn't have to?? It has become very clear that the toxic chemicals used for mining practices as well as the bi-products produced by such practices should be taken very seriously by communities looking to allow mine projects to enter their area. ~Cassandra Shendruk

  7. Now that I have this stuck in my head...

    Industry and pollution are chiefest among the hallmarks of human arrogance for that very reason. As we seem to think technology has made us invincible (at least in Western Society), in spite of the fact that species which are often hardier than we are slowly (or rapidly) going extinct. I would actually be curious to know what the carrying capacity is for this valley, and how the mine would affect that number based on land use and toxins released into the environment. I am willing to bet that that number would decline as viable resources decrease. If you were to look at our medical system as an ecosystem, you would see that the carrying capacity has already been exceeded well beyond the threshold, and the system is collapsing. This is the last thing we need.

  8. These dangerous materials are found in a lot of different areas around Canada, and the areas still get mined. The big reason I can see is that the mines are usually pretty far away from any substantial population. With the Ajax mine, Kamloops is right next door and this could potentially be very bad for its citizens. It's a big issue that will need to be address correctly before any digging takes place. -Erik Vliegenthart
