一篇关于Simcoe鱼类污染情况的报告2010

[steve]

我原来认为北面的湖要比有工业区的Great Lakes的污染情况好的多，其实好的并不是太多。

Trends of legacy and emerging-issue contaminants in Lake Simcoe fishes
published August 2010 http://jackson.eeb.utoronto.ca/files/2012/10/Journal-of-Great-Lakes-Research_7_148-159.pdf

Conclusions
In conclusion, concentrations of total-PCB and total-DDT have generally declined in Lake Simcoe sport fishes (lake trout and whitefish) between the 1970s and 2007......
Contaminant concentrations were, for the most part, below the “complete restriction” consumption guidelines for the general population. The only exception was for the largest (N60 cm) lake trout, where concentrations of PCBs either approached or exceeded this most restrictive guideline. The risk to the sensitive population was of more concern for the larger, predatory fishes (lake trout, largemouth bass, northern pike, smallmouth bass, and walleye for mercury, and whitefish for PCBs). PCNs and PBDEs were below the consumption guidelines for the measured species. Overall, contaminant related issues appear to be of less or similar concern than in the Great Lakes.

看来很有必要切实抓好治理各地区各湖各类鱼的各种虫虫的问题....

鼠标有虫了

污染没办法，水自然循环就把污染物带到任何地方了。

虫子原来觉着河里多，水流动性强。但是grand river钓了这么些年，还真没发现虫子的。

站长，虫子都上屏幕了！

哎! 咋说呢? 都是杨总委员长和我去了趟"哭妻情"(COUCHICHING)搞婆吃给闹的....

你俩这次去哭泣情是立功了。否则，不知道还有多少人去那里钓吃虫鱼尼。要严格检查，把除虫工作落实到实处。

不说我真是不知道，应该是好事

流动的水，应该虫少。只有河里水流缓的水里虫容易繁殖。但如果鱼在河里时间长了，也会感染的。

这虫子跟在鼠标后面跑啊。
