Use of teflon is important if any organics analysis will be done. As someone who has done much organics analysis, and seen the chromatographic runs of samples that have come into contact with "plastic" during the collection, extraction, and clean-up phases of sample preparation, I believe it is...

I know that we never, well should have never, used any solvent rinse bottles that were anything other than polyethylene because of phthalate contamination. Phthalate esters really interfere with quantification of other organics because of co-elution. I'm not as familiar with metals analysis...

I didn't completely read Randy's post to see that I repeated his recommendations. Correct me if I'm wrong, but I believe teflon and polyethylene are one and the same.

This is why I said earlier that we need to be careful about any conclusions from these analyses, or the earlier studies. On the potential contamination of samples, be sure to use solvent and then acid washed polyethylene bottles for the samples. Polyethylene will not leach phthalates...

What do you expect to be the immediate benefits of this study that we as hobbyists will find helpful in determining what ASW would be best to use in our aquarium?

John, Think about why you were considering sending your money. If it is only to find out ASW composition, then great. That is an easy enough proposition. What I said is be careful about what you can infer from Dr. Shimek's study. The way I read it, metals were the implied culprit for the...

I've been away from the board for a while, and noticed this thread. Being an environmental toxicologist by education (PhD), an ecological risk assessor, experienced in toxicity testing and reviewing toxicity tests, I found this thread intriguing. I went back and read Dr. Shimek's article in...

Mary, It is necessary for industry and preservation to go hand in hand. Like it or not, the world is becoming more capitalistic, and as such, that is what is going to end up determining the bottom line. We just have to determine how the natural world fits into the economic equation. Without...

I have been absent from this board for a few months, decided to check in just to see what is up, and this thread catches my eye. If he does not wish to participate, fine. It is a free country and he can do what he wants. However, as was posted by a couple of people, I suspect his ego won't...

I still think that the top photo is a dolphin. Dolphins, at least the ones I have worked with, do not have the earlier refered to shading. They were more or less solid grey/blue. So one turned on its side in the conditions that are evident in that photo is going to be all gray. If you look...

After looking at the pictures some more, I still say the first picture is a dolphin. The second two it is hard to say. The last one might be a shark. You can see what appear to be gill slits on the left side (as we see it in the picture) of the head, typical of a shark and not of a dolphin...

Dolphin. Top picture is of the animal turned to the side, so the horizontal tail is turned vertical. Also, in the same picture, look at the head, that is the definate shape of a dolphin head.

I guess I am going to have to visit the sump!
