Environmental Chemistry Laboratory

The QPP has three laboratories the Environmental Chemistry Laboratory (ECL) in Bay St. Louis, MS, and the Analytical Chemistry Laboratory (ACL) and the Microbiology Laboratory at the Environmental Science Center, both at Fort Meade, MD. The ECL is heavily involved with method validation efforts. The ACL evaluates enforcement analytical methods for product chemistry to ensure that the ingredient statements on the label are accurate and evaluates residue analytical methods for...

Environmental Chemistry. Requirements for data on pesticides in the environment include both laboratory and field studies. The purpose of these studies is to identify and assess the potential ha2ards associated with each use of a pesticide in the environment in which it is to be used (20). 

High school students should have a greater understanding of global environmental issues. This can be accomplished by using environmentally-relevant examples to teach high school chemistry. Appropriate demonstrations and laboratory experiments that illustrate these topics are suggested. To incorporate additional environmental chemistry in die secondary curriculum, help from environmental scientists will be needed.

The ECL evaluates analytical methods for detecting pesticide residues in the environment to ensure that the methods are suitable for monitoring pesticide residues in soil and water. State, tribal and federal laboratories may access an Index of Environmental Chemistry Methods for a list of available methods. The ECL also provides the State pesticide laboratories with technical and QA support and training in pesticide analytical chemistry.

Boron and arsenic are natural components of soil and are both present as oxyanions. Boron is present as boric acid or borate polymers, and arsenic is present as arsenate. While boron is weakly held by soil, arsenic is similar to phosphate in its interactions with soil constituents. Boron is an essential nutrient for plants however, it is also toxic to plants at relatively low levels. Arsenic is toxic. The laboratory chemistry of both of these elements is well understood, but their environmental chemistry, speciation and movement, is less well understood [23-27],... 

The ability to provide accurate and reliable data is central to the role of analytical chemists, not only in areas like the development and manufacture of drugs, food control or drinking water analysis, but also in the field of environmental chemistry, where there is an increasing need for certified laboratories (ISO 9000 standards). The quality of analytical data is a key factor in successfully identifying and monitoring contamination of environmental compartments. In this context, a large collection of methods applied to the routine analysis of prime environmental pollutants has been developed and validated, and adapted in nationally or internationally harmonised protocols (DIN, EPA). Information on method performance generally provides data on specificity, accuracy, precision (repeatability and reproducibility), limit of detection, sensitivity, applicability and practicability, as appropriate. 

Mechanisms of Mo environmental chemistry. Many of the chemical reactions that shape the distribution of Mo in the environment are still not well imderstood, as seen above in discussions of Mo adsorption to Mn oxides and removal in reducing systems. It is likely that different reaction pathways will impart different isotope effects. Hence, coupling of laboratory and well-constrained field studies should provide new insights into Mo environmental chemistry. Theoretical modeling of Mo isotope effects would also be useful in this context, as is proving true for Fe isotopes (Schauble et al. 2001).

One of the points made in Schwenz and Moore was that the physical chemistry laboratory should better reflect the range of activities found in current physical chemistry research. This is reflected in part by the inclusion of modem instrumentation and computational methods, as noted extensively above, but also by the choice of topics. A number of experiments developed since Schwenz and Moore reflect these current topics. Some are devoted to modem materials, an extremely active research area, that I have broadly construed to include semiconductors, nanoparticles, self-assembled monolayers and other supramolecular systems, liquid crystals, and polymers. Others are devoted to physical chemistry of biological systems. I should point out here, that with rare exceptions, I have not included experiments for the biophysical chemistry laboratory in this latter category, primarily because the topics of many of these experiments fall out of the range of a typical physical chemistry laboratory or lecture syllabus. Systems of environmental interest were well represented as well. 

As we have seen in Parts II and III, environmental chemistry is based on laboratory experiments as well. For instance, we can determine the relevant physicochemical... 

Increased environmental concern has accelerated research on the analysis of trace elements in fuels in many university and governmental facilities. Because instruments such as mass spectrometers and nuclear reactors for neutron activation analysis are available, much of this research uses sophisticated instrumentation and techniques. However, the wet chemistry laboratory is still the only available source of chemical...

Despite the extremely low concentrations of the transuranium elements in water, most of the environmental chemistry of these elements has been focused on their behavior in the aquatic environment. One notes that the neutrality of natural water (pH = 5-9) results in extensive hydrolysis of the highly charged ions except for Pu(V) and a very low solubility. In addition, natural waters contain organics as well as micro- and macroscopic concentrations of various inorganic species such as metals and anions that can compete with, complex, or react with the transuranium species. The final concentrations of the actinide elements in the environment are thus the result of a complex set of competing chemical reactions such as hydrolysis, complexation, redox reactions, and colloid formation. As a consequence, the aqueous environmental chemistry of the transuranium elements is significantly different from their ordinary solution chemistry in the laboratory.
