Use, development and improvements in the protocol of whole-sediment toxicity identification evaluation using benthic copepods
(Elsevier B.V., 2015-02-28)
The whole-sediment Toxicity Identification Evaluation (TIE) approach is a useful technique that allows for the identification of the contaminants responsible for the toxicity of complex sediment samples. This study aimed ...
Levels of metals and toxicity in sediments from a Ramsar site influenced by former mining activities
(Elsevier B.V., 2019-04-30)
This study aimed to evaluate the sediment quality in a Ramsar site located in the Southeast Brazil, by using several lines of evidence (LOEs). Chemical and sedimentological analyses, ecotoxicological tests, and whole ...
Sediment toxicity identification evaluation (TIE phases I and II) based on microscale bioassays for diagnosing causes of toxicity in coastal areas affected by domestic sewage
(Wiley, 2017)
Domestic sewage is a major problem in highly urbanized coastal areas worldwide. In the present study, toxicity identification evaluation (TIE) phases I and II were applied to sediment interstitial water from 2 locations ...
