But in science research that might be a problem. A study has recently been published in the journal Science that establishes that the leeching from plastics that we've long known about from activities like microwaving can also affect liquids at room temperature. Since much of the biological research that occurs uses disposable plastics, this is a concern. Making the concern worse, a lot of the molecules that leech out of plastics have similar chemical structures to hormones in mammals. Thus, when we use plastic tubes and trays for our research we can be having the cells or tissue that we're working with affected by these quasi-hormonal substances. Andy Holt, the lead researcher of the study and professor of pharmacology at the University of Alberta's Faculty of Medicine & Dentistry, has shown that using plastic lab equipment can skew or ruin the results of medical experiments. By using mass spectrometry to analyze the solutions at the molecular level, Holt and his col...
