"As a result of numerous consumer complaints of dizziness and nausea, Promofoods requested that eight million cans of tuna be returned for testing last year. Promofoods concluded that the cans did not, after all, contain chemicals that posed a health risk. This conclusion is based on the fact that the chemists from Promofoods tested samples of the recalled cans and found that, of the eight chemicals most commonly blamed for causing symptoms of dizziness and nausea, five were not found in any of the tested cans. The chemists did find that the three remaining suspected chemicals are naturally found in all other kinds of canned foods."
The conclusion from Promofoods that dizziness and nausea discussed in the complaints are not resulted from its tuna cans is drawn from the experiment results from a group of chemists from the enterprise. The results reveal that five out of eight poisonous chemicals that may cause dizziness and nausea are not traced in test samples, while the other three chemicals present in the samples are also found in other canned foods.
There are numerous reasons to discredit this conclusion. First of all, the fact that the chemists conducting the test are all from Promofoods severely compromised the validity of the test. Since these chemists are affiliated to the company it is highly unlikely that they will remain neutral in the process of the test. Promofoods may force them to alter test results or set up the test in such a way that adverse test results are less probable. And it is natural for those chemists to yield, because they as employees of the company may want to protect the company from incurring possible losses.
Besides that, the chemists only tested eight chemicals that are most commonly blamed for causing dizziness and nausea. This is clearly not enough to conclude that the canned tuna from Promogoods does not pose a health risk, as there may be other deleterious chemicals or pathogens existing in those tuna cans. In fact, it is possible that there are two or more chemicals which may not cause dizziness and nausea simultaneously but may bring one of the two symptoms separately.
Furthermore, even though the three chemicals found by the Promofoods chemists are also present in other canned foods, it is unsound to assume that the three chemicals do not have adverse effect to human body. Actually it has already been discussed that these three chemicals are considered substances that are most blamed for causing dizziness and nausea. Their presence in other products may be justified as the amount is extremely low. Yet if a large quantity of these three chemicals is found in the tuna cans of Promofoods, then consuming such tuna cans may be healthily risky.
Last but not least, there is no information about the size of the sample. If the sample size is too small, then it is possible that other canned tuna may contain those chemicals that threaten the health of consumers.
水平实在有限 见谅哈。。

没有结尾段总结的话会不会不太好?
个人感觉样本容量大小问题有点儿吹毛求疵,不应该单独列为一个错误,只需要在其他错误的后面顺带提一句。例如可以和第二个辩驳点一起说,让步一下即使调查公正,样本用量也有可能有问题。
PS:感觉你的语言真好 好羡慕。 用了很多红宝的词汇,我每次都想不起来用 哎。。。
