This paper describes the ecotoxicological evaluation of five organic contaminants frequently detected in marine sediments (tributyltin, triphenyltin, benzo[a]pyrene, fluoranthene, and PCB 153) using three marine species (Vibrio fischeri, Tetraselmis suecica, and Tisbe battagliai). The sensitivity of each species varied for all compounds. The triorganotins were consistently the most toxic to all species. The applicability of each test system to assess the acute toxicity of environmental contaminants and their use in Toxicity Identification Evaluation (TIE) is discussed. Suitability of the Microtox and T. battagliai tests for employment in TIE studies were further assessed through spiking experiments with tributyltin. Results demonstrated that …

Currently interest in pharmaceuticals as potential environmental contaminants has increases significantly. This is due to the awareness of the possible adverse effects to human health and the environment caused by such contaminants. Within the past few years, the highly prescribed antidepressants, selective serotonin reuptake inhibitors (SSRI), have received attention as their occurrence in the environment has been recently documented. Prior to this, there was very little known about the ecotoxicity of SSRIs, and in particular sertraline hydrochloride. Similarly the cholesterol-lowering drugs, known as statins are among the most frequently prescribed agents in Ireland and worldwide for the treatment of coronary …


Combination Of Natural Variability Estimation With Real Time Measurement For Mushroom Shelf Life Assessment., Leixuri Aguirre Jan 2008

Combination Of Natural Variability Estimation With Real Time Measurement For Mushroom Shelf Life Assessment., Leixuri Aguirre

Doctoral

The shelf life of mushrooms (Agaricus bisporus) is affected by the natural variability of the produce which influences the perishable vegetable quality. One of the main causes of this variability is non-homogeneity in the product maturity at harvest, resulting in each vegetable batch being at a different stage of senescence. The present work aims to study a new approach to improve the assessment of the shelf life of mushrooms (Agaricus bisporus) taking into account this variability. The study of variability involved the: i) study of the shelf life, quality parameters and variability of the mushrooms and modelling these experimental laboratory …
