Applicability of Tedlar{trademark} bags to aqueous sampling for ambient toxicity testing: Adsorption of trace metals
Journal Article
·
· Environmental Toxicology and Chemistry
Many materials commonly used to collect and store samples for ambient toxicity testing will readily sorb and/or leach contaminants. Previous work indicates that Tedlar (polyvinylfluoride) sampling bags are largely inert toward organics. The authors report here that this material is similarly inert to Co{sup 2+}, Cu{sup 2+}, Zn{sup 2+}, Sb{sup 3+}, Pb{sup 2+} in neutral solution. They found no trace metal adsorption at low pH and only slight adsorption (mean loss = 2.1 ppb) at neutral pH from 100-ppb solutions held in Tedlar bags for 24 h.
