Green Chemistry

Green Chemistry is a philosophy rather than a discipline, and the toxicologist has an important role in the implementation of this philosophy.   Broadly speaking, the goal of green chemistry is to reduce chemical pollution starting at the molecular level.  The 12 Principles of Green Chemistry, co-authored by John Warner and Paul Anastas in the mid-1990’s, laid out the framework for the “greening” of the field of chemistry.  By minimizing or eliminating the hazards related to raw materials, processes and products, adoption of the principles of Green Chemistry ...

Venomous or Poisonous – Animals, Plants, Mushrooms, and More

Venomous animals, poisonous plants, mushrooms, and substances produced by microbes, inflict considerable damage to humans and other animals throughout the world.  In scientific lingo, the entire subject is referred to as toxinology and the injurious natural substances as toxins. Thus, toxinology is a subset of the broader discipline of toxicology, and toxins could be considered a sub-category of toxicants, which is the proper word to use more generally for hazardous substances. Venomous organisms use a specialized delivery system such as fangs to deliver their venom.  ...

Reproductive and Developmental Toxicity Hazards

Any chemical or other factor such as heat stress, radiation, infectious disease or improper diet that causes harm to an adult can interfere with reproduction or a child’s development.  But some factors can cause such harm to the developing child in the womb at doses or exposures lower than those that cause any obvious harm to a potential parent.  These factors are then designated as selective reproductive and/or developmental hazards.  Reproductive hazards can affect fertility by interfering with the normal development and function of the egg and sperm cells, interf...

What is Toxicology?

The Society of Toxicology defines toxicology as the study of the adverse effects of chemical, physical, or biological agents on people, animals, and the environment.  Toxicologists are scientists trained to investigate, interpret, and communicate the nature of those effects.   Most toxicologists focus on chemical agents, although some are experts about harmful effects of physical agents such as radiation.  Toxicology is an interdisciplinary science, integrating information from biology and virtually all of its subspecialties (e.g., genetics, endocrinology and molecular ...
