The synergistic action between antimony oxide and most types of halogenated FRs has been used with plastics for many years, and there are many highly efficient antimony/halogen systems in use. The combination is particularly effective, in controlled amounts, in plasticized PVC compounds. In other polymers that do not contain a halogen, a suitably chlorinated or brominated compound needs to be added to achieve the required properties. A special grade should be used if translucency is required. 

Antimony is not classified as a carcinogen, but it is a hazardous material and its use in most countries is controlled by the relevant regulations for conditions

The two main federal agencies involved in the protection of human health and the environment are the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA). EPA s principal concern is the protection of the environment, in most cases, the area outside of an industrial faciUty. There are 10 regional offices that carry out the regulatory functions of the agency (Table 1). Primary laws covered by EPA are the Clean Air Act Amendments (CAAA), the Clean Water Act (CWA), Resource Conservation and Recovery Act (RCRA), Comprehensive Environmental Response, Compensation, and LiabiUty Act (CERCLA), Toxic Substances Control Act (TSCA), and Eederal Insecticide, Eungicide, and Rodenticide Act (FIFRA). 

The main objectives of RCRA ate to protect pubHc health and the environment and to conserve natural resources. The act requires EPA to develop and adininistet the following programs soHd waste disposal practices providing acceptable protection levels for pubHc health and the environment transportation, storage, treatment, and disposal of hazardous wastes practices that eliminate or minimize hazards to human health and the environment the use of resource conservation and recovery whenever technically and economically feasible and federal, state, and local programs to achieve these objectives.

The Toxic Substances Control Act (TSCA) was enacted in 1976 to identify and control toxic chemical ha2ards to human health and the environment. One of the main provisions of TSCA was to estabUsh and maintain an inventory of all chemicals in commerce in the United States for the purpose of regulating any of the chemicals that might pose an unreasonable risk to human health or the environment. An initial inventory of chemicals was estabhshed by requiring companies to report to the United States Environmental Protection Agency (USEPA) all substances that were imported, manufactured, processed, distributed, or disposed of in the United States. Over 50,000 chemical substances were reported. PoUowing this initial inventory, introduction of all new chemical substances requires a Premanufacturing Notification (PMN) process. To be included in the PMN are the identity of the new chemical, the estimated first year and maximum production volume, manufacture and process information, a description of proposed use, potential release to the environment, possible human exposure to the new substance, and any health or environmental test data available at the time of submission. In the 10 years that TSCA has been in effect, the USEPA has received over 10,000 PMNs and up to 10% of the submissions each year are for dyes (382)...

The reasons for such strict regulation of air pollution are obvious protecting human health and the environment. Potential air pollutants are not only toxic in many cases, but they can travel over great distances, thereby impacting areas remote from the sources of emissions. There are two environments that are of concern, once chemicals are emitted to the surroundings ... 

The technical differences between site problems at RCRA facilities and CERCLA sites sometimes may be difficult to distinguish, owing to similarities in present or past uses of the site, in hydrogeologic setting, and/or in the types of substances disposed, spilled, or otherwise managed at the site. Consequently, many technical aspects of the study and remediation of releases of hazardous wastes and constituents from RCRA facilities often will closely parallel those at Superfund sites, and cleanups under both statutes must achieve similar goals for protection of public health and the environment. Additionally, activities which would be termed removal actions or expedited response actions under CERCLA may be undertaken by owners and operators under RCRA. In the RCRA context, such actions are termed interim measures, as will be discussed in subsequent chapters. 

Where there is an imminent threat to human health and the environment, as well as in some nonemergency situations, the regulatory agency may ascertain that a response is appropriate prior to the completion of the RCRA Facility Investigation or the Corrective Measures Study. Hence, the decision for interim measures can be made based on the immediacy as well as the magnitude of the potential threat to human health or the environment the nature of appropriate Corrective Action the implications of deferring Corrective Action until the RCRA Facility Investigation and Corrective Measure Study is complete and other factors. 

Early in the Corrective Action process, a decision may be made concerning whether or not containment is necessary to protect human health and the environment (HHE). If the release or threatened release presents danger to HHE, immediate action must be taken to halt migration. Under these circumstances, actions termed "Interim Measures" may be required, and excavation or containment measures may be directed by the regulatory agency. However, the Owner/Operator will be responsible for their implementation. In the event that containment is not required as an interim measure, containment may still be needed as part of the overall Corrective Action to halt the pollution migration if wastes or contaminants are to be left on-site. 

After each issue outlined in the evaluation criteria has been developed for each corrective measure, the selection of the most appropriate alternative can be made. Trade-offs among health risks, environmental effects and other pertinent technical, environmental and human health factors enter into this decisionmaking process. In the RCRA context, cost is not a factor in the selection process except when two or more corrective measure alternatives are determined by EPA to provide similarly adequate levels of protection of human health and the environment. 

The Clean Air Act is the comprehensive Federal law that regulates air en stationary, and mobile sources. This law authorizes the U.S. Environmental Protection Agency (EPA) to establish National Ambient Air Quality Standards (NAAQS) to protect public health and the environment. The goal of the Act was to set and achieve NAAQS in every state by 1975. This ng of maximum pollutant standards was coupled with directing the states to develop state... 

Increasingly, safety, health, and the environment are becoming parts of the same SHE department in industry. This should help to avoid incidents such as those described in Section 2.11. Unfortunately, there are few signs of a similar integration in government departments.

M.3 Polychlorinated biphenyls (PCBs) were once widely used industrial chemicals but were found to pose a risk to health and the environment. PCBs contain only carbon, hydrogen, and chlorine. Aroclor 1254 is a PCB with molar mass 360.88 g-mol. Combustion of 1.52 g of Aroclor 1254 produced 2.224 g of CO, and combustion of 2.53 g produced 0.2530 g of H20. How many chlorine atoms does an Aroclor 1254 molecule contain ... 

This analysis has demonstrated that pesticide use in the world could be reduced by approximately 50% without any reduction in crop yields (in some cases increased yields) or the food supply. This effort would require applying pesticides only-when-necessary plus using various combinations of the nonchemical control alternatives currently available (34). Although food production costs might Increase slightly (0.5% to 1%), the added costs would be more than offset by the positive benefits to public health and the environment (15). 

Risks to human health and the environment will vary considerably depending upon the type and extent of exposure. Responsible authorities are strongly encouraged to characterize risk on the basis of locally measured or predicted exposure scenarios. To assist the reader, examples of exposure estimation and risk characterization are provided in CICADs, whenever possible. These examples cannot be considered as representing all...

Paraffins react with chlorine under the influence of light, heat, or catalysts to form chlorocarhons. The chlorocarhons are important in industry because of their own properties and because of their use as chemical intermediates in the synthesis of other compounds. Today, many of the chlorocarbons are regulated by federal and state agencies to limit their use because of detrimental effects on health and the environment. 

Environmental catalysis has its potential in improving innovations in the field of catalysis and highlighting the new directions for research driven by market, social, and environmental needs. Therefore, it can be concluded that environmental catalysis plays a key role in demonstrating the role of catalysis as a driver of sustainability by improving the quality of life and protecting human health and the environment...
