Researchers examine contaminants in hunted wildlife

August 09, 2017

Concerning environmental contaminants, game species are not subject to the same safety testing as commercially marketed livestock. A recent study sampled feral pigs, gray squirrels, and waterfowl from relatively uncontaminated habitats and areas of contamination.

Investigators found that many of the game species from contaminated areas had detectable levels of contaminants. A number of waterfowl tissues were above levels that might cause concern for the health of the birds and humans that consume game; however, the majority of tissue samples analyzed were below levels known to adversely affect wildlife health.

Of special concern are migratory waterfowl that can expose hunters to contaminants thousands of kilometers from point sources.

The study is published in the Journal of Wildlife Management.

Applied Contaminant Transport Modeling
by Chunmiao Zheng (Author), Gordon D. Bennett (Author)

The challenges facing groundwater scientists and engineers today demand expertise in a wide variety of disciplines–geology, hydraulics, geochemistry, geophysics, and biology. As the number of the subdisciplines has increased and as each has become more complex and quantitative, the problem of integrating their concepts and contributions into a coherent overall interpretation has become progressively more difficult. To an increasing degree transport simulation has emerged as an answer to this problem, and the transport model has become a vehicle for integrating the vast amount of field data... View Details


Modeling Groundwater Flow and Contaminant Transport (Theory and Applications of Transport in Porous Media)
by Jacob Bear (Author), Alexander H.-D. Cheng (Author)

In many parts of the world, groundwater resources are under increasing threat from growing demands, wasteful use, and contamination. To face the challenge, good planning and management practices are needed. A key to the management of groundwater is the ability to model the movement of fluids and contaminants in the subsurface. The purpose of this book is to construct conceptual and mathematical models that can provide the information required for making decisions associated with the management of groundwater resources, and the remediation of contaminated aquifers.

Environmental Contaminants in Biota: Interpreting Tissue Concentrations, Second Edition
by W. Nelson Beyer (Editor), James P. Meador (Editor)

Examining tissue residues of contaminants in biota reveals the movement of contaminants within organisms and through food chains as well as the context for understanding and quantifying injuries to organisms and their communities. Yet tissue concentrations of some contaminants are especially challenging to interpret and the ability of today’s analytical chemists to provide reliable analytical data of most important environmental contaminants often surpasses the ability of ecotoxicologists to interpret those data.

Ten papers suggest how to improve national regulations to require testing the impact on wild birds before pesticides and other chemicals are authorized for use. They offer a framework for testing and assessing the effects, case studies on assessment, and feedback to other groups that are responsible for revising avian test guidelines of the Organization for Economic Cooperation and Development (OECD). The conclusion makes 15 specific recommendations. Annotation c. Book News, Inc., Portland, OR (booknews.com) View Details

The Gulf of Mexico is an open and dynamic marine ecosystem rich in natural resources but heavily impacted by human activities, including agricultural, industrial, commercial and coastal development. The Gulf of Mexico has been continuously exposed to petroleum hydrocarbons for millions of years from natural oil and gas seeps on the sea floor, and more recently from oil drilling and production activities located in the water near and far from shore. Major accidental oil spills in the Gulf are infrequent; two of... View Details


Contaminant Transport Modeling through Saturated Porous Media: Using Finite Element and Finite Difference Methods

Groundwater quality varies due to the chemical, geochemical, and biochemical reactions of the pollutants in the subsurface flow systems. To reliably predict the fate of contaminant transport in groundwater, an accurate numerical modeling is required.
