我们这个城里有什么地方能钓到能吃的鱼吗？

我没有车，有没有坐BUS能到的？我看见有人在Clearwater River钓，那里面的鱼能吃吗？

这里水里有大量致癌物质，别吃。从油砂里面炼重油需要用diluent，地层深处的油砂里面有大量重金属铅，砷（砒霜），汞（水银），这些东西全部通过Extraction的洗沙工艺过程进入Tailings pond,然后渗透到当地水系，河，湖。鱼类是吸收这些重金属的载体。人若食用此鱼，慢性中毒还会引发各种癌症，包括皮肤癌、肺癌、膀胱癌的机率会比平常人大几十倍。

Research conducted for the Athabasca Chipewyan First Nation in northern Alberta has cast doubt on a government study about the town's water quality and its connection to cancer rates.

The study, by Kevin Timoney, was done to determine whether oilsands pollution is making people sick through the water supply.

Levels of polycyclic aromatic hydrocarbons rose between 2001 and 2005 in sediment in the Athabasca Delta, the report says, with current levels considered unsafe to aquatic life.

Resident Ray Ladouceur, who has fished on Lake Athabasca for about 50 years, said he has pulled deformed fish from his nets. He said he believes the fish are sick because of the chemicals from the oilsands in Fort McMurray.

"I've seen many changes in this, the water. There's all kinds of stuff coming down," Ladaceur said.

"You can see it right in the water, there's kind of a scum, I guess, flowing down the river."

Fort Chipewyan is located downstream from Fort McMurray, the heart of the province's oilsands development.
