  • Approaches to Chemical Control

    Hazardous material is anything that poses a threat to human health and the environment. Most hazardous materials are generated from chemicals. To provide the highest degree of protection for society and the environment from the dangers, stringent controls throughout the lifecycle of the material, starting with import or manufacture and ending with disposal, is necessary. Many governments consider ...

  • TSCA Reform: Is It Likely This Term?

    The Toxic Substances Control Act (TSCA) has remained largely unchanged since its enactment in 1976. After years of failed efforts to revise TSCA, and with the help of a motivated Democratic-lead Congress, TSCA legislative reform was off to a brisk start in 2009-2010, during which time over a dozen hearings were convened on how to improve the law. The momentum has slowed considerably since ...

  • Leaching kinetics of limonite and nontronite ores

    Bioleaching of nickel laterite ores is the extraction technology based on the use of heterotrophic micro-organisms and their organic acid products to dissolve metals from oxide minerals. This study examined the leaching kinetics of limonite and nontronite ores by metabolites including citric, lactic and malic acids. In addition the roles of acidolysis and complexolysis in the kinetic of metal ...

  • White paper - Chemical feed control

    The controls, alarms and external contacts are shown on the drawings. As the amount of chemical needed to neutralize the wastewater varies exponentially from neutral pH 7, special consideration must be given to control overshooting the pH. Chemicals, especially viscous caustic soda, must be fully mixed in the compartment before more is added. Rather than modulating the pump settings, the pump is ...

  • Relationship between water-soluble carbohydrates in fall and spring and vigor of spring regrowth in orchardgrass

    To clarify relationships among factors associated with winter stress in orchardgrass (Dactylis glomerata L.), water-soluble carbohydrate (WSC) concentration, resistance to snow mold, and tolerance to prolonged snow cover were evaluated under both conditions of natural infection and chemical control of snow mold. A total of 18 cultivars from Japan, Europe, and the United States were transplanted ...

  • REACHing Asia: Recent trends in chemical regulations of China, Japan and Korea

    Will EU REACH (Registration, Evaluation, Authorisation and Restriction of Chemical substances) influence and change the chemical regulatory systems of Asia, as EU RoHS has done in China, Japan and Korea? The answer is YES. China, Japan and Korea are (or will be) filling the regulatory gap they see between REACH and their chemical regulatory systems. With its advanced chemical regulatory system ...

  • California to Control Chemicals of Concern

    California has a well-established reputation as a trendsetter, but the gargantuan state may have outdone itself with the June 23 draft regulation released from the California Department of Toxic Substances Control (DTSC) for safer consumer product alternatives. The regulations are intended to implement the Green Chemistry Initiative signed into law by Gov. Schwarzenegger in ...
