Statistical reporting deficiencies in environmental toxicology

Null hypothesis significance testing is one of the most widely used forms of statistical testing in environmental toxicology. In this short communication, the authors show that the reporting of statistical information when using null hypothesis significance testing is frequently inadequate in environmental toxicology research. The authors demonstrate this by analyzing the statistical ...

Toxicological and Environmental Safety Data - Case Study

Introduction AGRAGEL is a cross-linked copolymer of acrylic acid and acrylamide partially neutralized as potassium/ ammonium salt. The polymer is in its dry form a granulate and forms a gel-like material upon addition of water or aqueous solutions. Due to the cross-linking it is insoluble in water. Uptake of water is facilitated mainly by the negative carboxylic groups of the polymer and ...

Applications and implications of neurochemical biomarkers in environmental toxicology

Thousands of environmental contaminants have neurotoxic properties though their ecological risk is poorly characterized. Contaminant‐associated disruptions to animal behavior and reproduction, both of which are regulated by the nervous system, provide compelling evidence of harm to decision makers but such apical endpoints are of limited predictive or harm preventative value. Neurochemical ...

Zebrafish as a model system to study toxicology

Monitoring and assessing the effects of contaminants in the aquatic eco‐environment is critical in protecting human health and the environment. The zebrafish has been widely used as a prominent model organism in different fields because of its small size, low cost, diverse adaptability, short breeding cycle, high fecundity, and transparent embryos. Recent studies have demonstrated that ...

Toxicological implications of microcystins on zebrafish embryos in the presence of other environmental pollutants

Microcystins (MCs) interact with environmental contaminants as well as various other congeners of the MCs family in the natural environment and with antioxidants in the exposed organisms. These interactions are likely to modify the toxicological behavior of MCs at the cellular level. The present study was conducted to understand the toxicological response of extracellular MCs in aquatic systems ...

The interplay of environmental toxicology and chemistry in the development of sediment quality criteria

The search for rational methods to develop criteria for various media—water, sediment, and tissue—and various receptors—aquatic, terrestrial, and human—has been a consistent and continuous enterprise from the beginning of environmental toxicology. Many of the 100 most frequently cited papers in Environmental Toxicology and Chemistry directly or indirectly address topics relevant to criteria. ...

It is time to develop ecological thresholds of toxicological concern to assist environmental hazard assessment

The Threshold of Toxicological Concern (TTC) concept is well established for assessing human safety of food‐contact substances and has been reapplied for a variety of endpoints including carcinogenicity, teratogenicity, and reproductive toxicity. The TTC establishes an exposure level for chemicals, below which no appreciable risk to human health or the environment is expected based upon a de ...

Environmental surveillance and monitoring—The next frontiers for high‐throughput toxicology

High‐throughput toxicity testing technologies along with the World Wide Web are revolutionizing both generation of and access to data regarding the biological activities that chemicals can elicit when they interact with specific proteins, genes, or other targets in the body of an organism. To date, however, most of the focus has been on the application of such data to assessment of individual ...

Chemical and toxicological assessment of a full‐scale biosolid compost

The impact of a full‐scale biosolid composting plant on the fate of a broad range of priority organic pollutants was investigated. Chemical analysis was performed at different steps of the process during two seasons. Simultaneously, the toxicological quality was assessed using estrogen α‐, dioxin‐, and pregnane X‐receptor reporter cell lines. Mass‐balance calculation highlighted the removal of ...

Toxicological risks to humans of toxaphene residues in fish

A revised risk assessment for toxaphene was developed, based on the assumption that fish consumers are only exposed to toxaphene residues that differ substantially from technical toxaphene due to environmental degradation and metabolism. In vitro studies confirmed that both technical toxaphene and degraded toxaphene inhibit gap junctional intercellular communication that correlates with the ...

Hormesis: Why it is Important to Toxicology and Toxicologists - Critical Review

This article provides a comprehensive review of hormesis, a dose–response concept that is characterized by a low-dose stimulation and a high-dose inhibition. The article traces the historical foundations of hormesis, its quantitative features and mechanistic foundations, and its risk assessment implications. The article indicates that the hormetic dose response is the most fundamental dose ...

Selecting the best design for non‐standard toxicology experiments

Although many experiments in environmental toxicology use standard statistical experimental designs, there are situations that arise where no such standard design is natural or applicable due to logistical constraints. For example, the layout of a lab may suggest that each shelf serve as a block with the number of experimental units per shelf either greater than or less than the number of ...

Review of toxicological effects caused by episodic stressor exposure

Water quality monitoring tools that rely on data from stress‐response tests with continuous exposure at constant concentrations are not always appropriately protective when stressor exposure in the field is episodic in nature. The present study identifies various approaches that have attempted to account for episodic stressor exposure, describes the development of a toxicological effects database ...
