The Chemical Weapons Convention requires, among other things, that the signatories to the convention--which includes the United States--destroy by April 29, 2007, or as soon possible thereafter, any chemical warfare materiel that has been recovered from sites where it has been buried once discovered. For several years the United States and several other countries have been developing and using technologies to dispose of this non-stockpile materiel. To determine whether international efforts have resulted in technologies that would benefit the U.S. program, the U.S.
A notable achievement by the U.S. Army as of early 2012
is that 90 percent of the legacy chemical weapons and other
chemical warfare materiel (CWM) from the Second World
War and cold war eras and then stockpiled by the United
States have been safely destroyed.
Whatever cumulative risk
had been posed by the existence of this CWM to communi-ties surrounding the six military sites where it was guarded
and safely maintained since the mid-twentieth century is
VOCs from process vents are, where possible, re-used within processes but this is dependent on
such factors as VOC composition, any restrictions on re-use and VOC value. The next
alternative is to recover the VOC calorific content as fuel and, if not, there may be a
requirement for abatement. A combination of techniques may be needed, for example: pre-
treatment (to remove moisture and particulates); concentration of a dilute gas stream; primary
removal to reduce high concentrations, and finally polishing to achieve the desired release
In many industries, including telecommunications, transportation, and energy as well as
chemicals and food and beverages, firm performance and success largely depend on external
factors. The main levers for profitability in those industries are heavily influenced by regula-
tory actors who impact strategic choices of corporate management.
Endoplasmic reticulum-associated degradation of newly
synthesized glycoproteins has been demonstrated previously
using various mammalian cell lines. Depending on the cell
type, glycoproteins bearingMan9 glycans and glycoproteins
bearing Man5 glycans can be efficiently degraded. Awide
variety of variables can lead to defective synthesis of lipid-linked oligosaccharides and, therefore, in mammalian cells,
species derived fromMan9GlcNAc2 orMan5GlcNAc2 are
often recovered on newly synthesized glycoproteins. ...
Properties of CNT:
• Electrical :
– High electric conductivity (higher than copper)
– Easy process for Conductive Semi-conductive
• Thermal :
– High thermal conductivity (higher than silicon)
– Stable at high temperature
• Physical :
– 100 times stronger than steel but very light
– Elastic behavior (Pressing CNT tip bend and recover to
its original state)
• Chemical :
– Rarely react with other compounds
– Chemically stable
Chapter 3 INHALATION HAZARDS IN REFINERIES
Operations of the petroleum industry can logically be divided into production, refining, and marketing. Production includes locating and drilling oil wells, pumping and pretreating the crude oil, recovering gas condensate, and shipping these raw products to the refinery or, in the case of gas, to commercial sales outlets. Refining, which extends to the conversion of crude to a finished salable product, includes oil refining and the manufacture of various chemicals derived from petroleum.
The sick have been held hostage for their money or intangible
assets since time immemorial. Doctors, even primitive and
natural healers, surround themselves with mystery as they use
herbs or chemicals and incantations or “prognoses” to help the
sick recover. Today, the medical industry (doctors and their
suppliers and insurers) take a significant amount of the worker's
The Blacksmith Institute’s database contains almost 350 sites contaminated with mercury, putting close to
10 million people at risk from the identified sites. It is the second most prevalent pollutant in the database.
The top sources of mercury pollution are artisanal gold processing, mining and ore processing, coal mining,
processing and localized air pollution related to coal combustion at poorly controlled sites, and chemical
manufacturing, notably for older chlor-alkali plants making chlorine.
Artisanal mining of gold ores and processing using mercury is common worldwide.
Concurrent treatment of source area saturated and unsaturated zones usually
requires the integration of chemical oxidation with other remedial technologies that
target unsaturated zone contamination (e.g., soil vapor extraction). Frequently,
soil vapor extraction, which is used to treat the unsaturated zone, is included as a
component of chemical oxidation remedial solutions even if there is no specific
need to treat unsaturated soils in the source area.
Worldwide consumption of organic products has
experienced tremendous growth, often surpassing
the U.S. figures of 20 percent annual gain. Much of
the increase in worldwide consumption has been
fueled by consumers’ demand for GMO-free
products. Because GMOs are disallowed in organic
production and processing, organic products auto-
matically are designated as GMO-free at the
marketplace. European consumers have led the
demand for organic products, particularly in coun-
tries such as the Netherlands, Italy, and Austria.
