The present study provides the only available data on toxicity of copper, cadmium and hydrocarbon toxicants on sponge larval settlement.
Flow cytometry is a cutting edge technique that can provide data on how toxicants can alter the quality and quantity of the immune response after exposure.
Classic reductionist thinking in toxicology focuses on "one toxicant, one outcome" research.
The first model, herein referred to as the one-compartment model A, was developed to predict the bioaccumulation processes of organic chemicals in aquatic ecosystems with the aim of providing data on site-specific toxicant concentrations and associated bioconcentration, bioaccumulation, and biota sediment accumulation factors in organisms of aquatic food webs.
It has been generally agreed that effect-based identification of key toxicants as well as analysis, modelling and assessment of bioavailability and bioaccumulation are needed, along with better evaluation of monitoring data on contamination, toxicity, ecological quality and ecosystem services on a large scale.
We also lacked data on other potential environmental toxicants in the serum of Mid-Ohio Valley residents that could have confounded associations with PFOA, and given the limited information on the causes of autoimmune diseases, we cannot rule out possible confounding by other unmeasured exposures or characteristics.
Many studies on toxicant or ischemia-induced acute renal failure (ARF) have provided data demonstrating the participation of a wide range of compounds that are known to modulate several processes such as nephrogenesis, regenerative response and inflammation [ 4- 11].
The CTD contains data on broad relationships between genes and environmental toxicants (we queried for metals), known effects of toxicants on gene expression, and genes encoding proteins that have altered metal-associated changes in protein abundance and protein activity.
A secondary aim was to provide data on the extent of exposure to selected toxicants in a unique population consisting of inner-city children who were already overexposed to one urban hazard, lead.
The clearest data on the deleterious effects of prenatal exposure to toxicants comes from the study of two metals, lead and mercury, and from epidemiological investigations of the effects of alcohol taken during pregnancy.
