Pollution intentional

U.S. —Canada Memorandum of Intent on Transbounday Air Pollution, Atmospheric Sciences and Analysis Work Group 2 Phase III Final Report,U.S. Environmental Protection Agency, Washington, D.C., 1983. 

The purpose of this subsection is to outhne the basic elements of a pollution-prevention cost-accounting system that incorporates both traditional and less tangible economic variables. The intent is not to present a detailed discussion of economic analysis but to help identify the more important elements that must be considered to properly quantify pollution-prevention options. 

The terms ambient air, ambient air pollution, ambient levels, ambient concentrations, ambient air monitoring, ambient air quality, etc. occur frequently in air pollution parlance. The intent is to distinguish pollution of the air outdoors by transport and diffusion by wind (i.e., ambient air pollution) from contamination of the air indoors by the same substances. 

We should note that in a general sense, the objective of pollution abatement is compliance. Whether we apply conventional controls or P2, the intent is to develop corrective actions that largely focus on the lowest achievable emission rate (LAER) technologies, and only sometimes on best available control technologies (BACT),... 

This chapter focuses on hardware. The intent is to provide a working description of pollution control hardware, and to highlight technologies and equipment that may be applicable to pollution prevention opportunities. 

The passage of the Clean Air Act Amendment (CAAA) on November 15, 1990, started a process for regulating the composition and quality of gasoline and diesel fuels sold in the United States. The CAAA s intent was to improve the nation s air quality by reducing ozone and other air pollutants. Title II of the CAAA requires the manufacture and sale of cleaner fuels in order to reduce evaporative and combustible emission of ... 

Reducing the intrinsic hazard of chemicals is the most effective and most fundamental of the risk reduction options available. Intrinsic risk reduction is based on the principle that the structure of a chemical drives hazard and molecular intentional, informed manipulation will result in the design of safer chemicals. Wastewater treatment plants employ large filters packed with granular activated carbon to remove polluted water. Synthetic chemists are... 

A successful modem hazardous industrial waste treatment program for a particular industry will include not only traditional water pollution control but also air pollution control, noise control, soil conservation, site remediation, radiation protection, groundwater protection, hazardous waste management, solid waste disposal, and combined industrial-municipal waste treatment and management. In fact, it should be a holistic environmental control program. Another intention of this handbook series is to provide technical and economical information on the development of the most feasible total environmental control program that can benefit both industry and local municipalities. Frequently, the most economically feasible methodology is a combined industrial-municipal waste treatment. 

The US Environmental Protection Agency recently announced its intention to develop and implement new Clean Air Act Standards for industrial coatings operations within the next year. These emission standards will eventually require companies involved in fabric printing, coating and dyeing operations to comply with Maximum Achievable Control standards. The Hazardous Air Pollutants emission limits that will apply to facilities and the impact on fabric coating operations are discussed. USA... 

Intentions by the EPA to more tightly regulate the emission of hazardous air pollutants through maximum-achievable-control-technology standards are briefly reported with reference to styrene emissions. The regulation would require that any facility that emits more than 100 tons of styrene annually, should retrofit with expensive ventilation equipment, and that a new facility of any size would have to install the same type of equipment. The composites industry considers this to be an expensive standard, which could put companies out of work. 

The Oil Pollution Act of 1924 was the first federal statute prohibiting pollution of waters strictly by oil. As indicated earlier, the Federal Water Pollution Control Act (FWPCA) of 1972 provided a comprehensive plan for the cleanup of waters polluted by oil spills and intentional or accidental release of oil into the water. The subsequent laws, including the Clean Water Act of 1977 and with its later amendments, provide for regulation of pollution of waters by oil spills and other forms of discharges. These legislations also incorporate certain provisions of the Rivers and Harbors Act of 1899, which was intended to prevent any obstruction to the use of navigable waters for interstate commerce. 

Because of this assertion, Ciamician can be considered the father of green chemistry, sharing with today s conception of this discipline the same disapproval of pollution, the same care for mankind, and the same intent to use natural resources. And the dream can today come true, thanks to modern technologies and to wider societal awareness and recognition. 

This is confusing. Why don t risk assessors simply decide what level of exposure is safe for each chemical, and risk managers simply put into effect mechanisms to ensure that industry reaches the safe level Why should different sources of risk be treated differently Why apply a no risk standard to certain substances (e.g., those intentionally introduced into food, such as aspartame) and an apparently more lenient risk-henefit standard to unwanted contaminants of food such as PCBs, methylmercury, and aflatoxins (which the FDA applies under another section of food law) Why allow technological limitations to influence any decision about health What is this risk-henefit balancing nonsense Aren t some of these statutes simply sophisticated mechanisms to allow polluters to expose people to risk ...

This chapter is concerned with the different types of wetland soil as sources, sinks and transformers of nutrients, particular nutrient deficiencies and mineral toxicides that commonly arise following submergence, and the fate of pollutants that are commonly added to submerged soils, both accidentally and intentionally. 

At the beginning of the twenty-first century new threats to human well being have emerged, which stem from terrorist activities. Potential use of chemical, biological, radiological and nuclear warfare (CBRN) in terrorist events is considered to be very likely, and on a small scale it has already been used in the past. CBRN threat however is not limited to malicious intentions and can be caused by a careless attitude towards the use of technology and equipment, breach of safety rules, or triggered by natural disasters or environmental pollution. 

As we will also show, polymers built on hydrophobic polyols and isocyanates are appropriate for the extraction of hydrophobic pollutants. The intent of most polyurethane research is to develop polymers of sufficient strength to meet the requirements of a particular application, for example, designing a polymer to extract an aromatic hydrocarbon from the air. As we begin to develop applications, we will use the principles of solvent extraction and use specific polyols matched to extractants.
