1. TITLE Aluminum Coatings Turn Green: IVD Process Delivers Environmentally Friendly Corrosion Protection
AUTHOR Holmes, Vernon Lee; Bridger, Mike
SOURCE Metal Finishing, Vol. 102, No. 12, December 2004, pp. 6-10
ABSTRACT
Ion vapor deposition (IVD) is a physical vapor deposition process for
applying pure aluminum coatings to workpieces of various alloys, mainly
for corrosion protection. The process is applied in various styles of a
vacuum coating machine called an Ivadizer. To prevent contamination of
the pure aluminum coating from oxygen and water vapor in the
atmosphere, the coating is applied to the substrates in a vacuum, which
makes generation of the metal vapor easier because
the boiling point is decreased from it atmospheric boiling point.
2. TITLE Chrome Comes Under Fire... Again
SOURCE Products Finishing, December 2004, vol. 69, no. 3, pp. 42-45
ABSTRACT
A proposed new standard for occupational exposure to hexavalent chrome
suggests lowering the permissible exposure limit to less than 1/50th
its current level. Here's a look at the proposed limits, how they were
conceived, and how the industry is responding.

TITLE A New Cure for Sticky Situations: High Performance and
Environmental Friendliness Help Radiation-Cured Adhesives Gain
Acceptance
AUTHOR Valero, Greg
SOURCE Chemical Week, July 21/28, 2004, vol. 166, no. 24, p. 27
ABSTRACT
"Better," "faster" and "cleaner" may sound like the selling points of a
new car, but many adhesives industry members are suing these words to
describe radiation curing. Simply put, these are the primary advantages
over competitive bonding chemistries. More and more end users are
reportedly seeing the light as the technology expands into many
applications, from food packaging to electronic equipment. Ultraviolet
(UV) and electron beam (EB) are the two most publicized forms of
radiation curing for adhesives. What is reportedly turning more end
users on to these technologies is radiation cured products utilize hot
melt, warm melt or liquid systems that are near 100 percent solids,
specially formulated to polymerize instantly to UV light or EB energy,
with no heat, water or solvents. And because an adhesive is not cured
until exposure to UV or EB, users can work with it, place it where they
want and have no fear of drying.
4. TITLE Musk Fragrances Found to be Antiestrogenic
AUTHOR Schaefer, Anke
SOURCE Environmental Science & Technology, February 15, 2004, vol. 38, no. 4, pp. 69A-70A
ABSTRACT
Some of the synthetic musk fragrances used in consumer goods can impair
estrogenic function in fish, according to research published in this
issue of ES&T (pp 997–1002). The study reveals that these
environmental pollutants could be significant endocrine disrupters, say
scientists from the Institute for Risk Assessment Sciences at Utrecht
University and the Netherlands Institute for Developmental Biology in
Utrecht. The research focuses on two polycyclic musks that are used as
fragrances in soaps, cosmetics, and cleaning products and often end up
in wastewater. What is unique about these compounds is that they are
the first to be reported with antiestrogenic activity on the basis of
an in vivo fish assay. While estrogenic chemicals mimic the behavior of
the female hormone estrogen, antiestrogenic chemicals impair the
activity of endogenous estrogens. Antiestrogenic pharmaceuticals, such
as tamoxifen, are used in breast cancer treatment and have been studied
extensively, but the antiestrogenic activity of
environmental pollutants has hardly been addressed so far, says Bart van der Burg, an author of the study.
5. TITLE The Evolution of Canada's Approach to Minimizing Environmental and Health Risks from Mercury
AUTHOR Hoskin, Wanda M.A.
SOURCE Industry and Environment, April - September 2004, vol. 27, no. 2-3, 2004, pp. 39-42
ABSTRACT
Human health concerns underlie Canada's approach to limiting releases
of anthropogenic mercury. Mercury is a naturally occurring element that
is ubiquitous in the environment. Routes of exposure are complex. While
the scientific literature and policies and regulations refer to mercury
levels in the environment, it is methylmercury (a neurotoxin) that is
referred to. Methylation of particulate and reactive mercury into
organic methylmercury produces toxic effects. The Canadian government
has promulgated a range of policies and regulations to minimize health
and environmental risks from this and other toxic chemicals. It also
works with Canada's provincial and territorial governments and is
active in bilateral, regional and international activities.
6. TITLE ACCA Encourages Improved Sustainability Reporting
SOURCE Business and the Environment, October 2004, vol. XV, no. 10, pp. 6-7
ABSTRACT
A global overview of corporate reporting that reviewed nearly 5,000
reports has concluded that businesses worldwide are failing to produce
enough sustainability reports and the governments are doing little to
encourage such reporting. The publication entitled "Towards
Transparency: Progress on Global Sustainability Reporting 2004," was
prepared by the Association of Chartered Certified Accountants and
CorporateRegister.com. The new report looks at the status of
sustainability reporting around the world and identifies key trends. In
general, the report notes that marked improvements in coverage,
standards, and credibility will be needed in the next few years.
7. TITLE Report Highlights Benefits of Chemical Management Services
SOURCE Business and the Environment, October 2004, vol. XV, no. 10, pp. 9-10
ABSTRACT
The Chemical Strategies Partnership has released its second
industry-wide study examining the use of chemical management services
(CMS).
Entitled "Chemical Management Services Industry Report
2004," the report indicates that the CMS market has grown approximately
50% since 2000, when the first CMS overview was completed, and
continued steady growth is expected. Under a CMS arrangement, companies
contract with a service provider to supply and manage chemicals and
related services. Through CMS relationships, companies strive to reduce
costs, and also achieve environmental benefits from reduced chemical
volume, reduced emissions, reduced risks, and better data for reporting.
8. TITLE SEC to Improve Tracking of Environmental Risks
SOURCE Business and the Environment, September 2004, vol. XV, no. 9, pp. 5-6
ABSTRACT
The US Securities and Exchange Commission (SEC) has operations underway
to enhance disclosure of US companies' environmental assets and
liabilities. The planned SEC activities are documented in the US
Government Accounting Office report entitled Environmental Disclosure -
SEC Should Explore Ways to Improve Tracking and Transparency of
Information. The document was produced in response to a request by
three US Senators to determine: (1) key stakeholders' views on how well
the SEC has defined the requirements for environmental disclosure; (2)
the extent to which companies are disclosing environmental information
in their filings with the SEC; (3) the adequacy of the SEC;s efforts to
monitor and enforce compliance with disclosure requirements; and (4)
what actions experts suggest for increasing and improving environmental
disclosure.
9. TITLE Metal Cleaning Made Easy: A Fluidized Bed System is a Cost-Effective Option for Degreasing Processes
AUTHOR Barletta, M.; Guarino, S.; Tagliaferri, V.
SOURCE Metal Finishing, Vol. 102, No. 12, December 2004, pp. 23-28
ABSTRACT
Traditional degreasing processes employ chlorinated solvents in a
liquid or vapor state in order to remove oils and oil-borne soils from
previously processed parts, such as chips, metal fines, and fluxes.
Nevertheless, increased sensitivity to the environmental impacts of
cleaning agents has led to alternative cleaning processes. A novel and
unpublished eco-efficient degreasing technique has been analyzed in
this study, namely, surface cleaning by means of a fluidized bed of
hard particles. A spherical-shaped glass powder with variable mesh
sizes in the range of 100 to 800 microns was fluidized. The impact of
fluidized particles on the metal substrate caused accurate cleaning of
the surface of the workpiece without involving the use of any solvents
and without damaging the surface of the part to be degreased.
10. TITLE Shedding Light on Radiation Curing: An Overview of Ultraviolet Light and Electron Beam Curable Coating Technology
AUTHOR Pasternack, George
SOURCE Metal Finishing, Vol. 102, No. 12, December 2004, pp. 29-34
ABSTRACT
Ultraviolet (UV) and electron beam (EB) curable materials are unique
solvent-free compositions that cure (harden) in a fraction of a second
upon exposure to a UV or EB source. The absence of solvent eliminates
the need for large baking ovens used to process conventional
solvent-based coatings and inks. UV and EB curable coatings
significantly reduces solvent emissions into the atmosphere and
eliminates the potential fire hazards associated with conventional
coatings containing flammable solvents.
