Toxic substances pollutants

Contamination of local marine sediment by toxic chemical pollutants has been relatively well documented. The marine sediment POPs inventory was compiled based primarily on data generated from a major consultancy study on local toxic substances pollution (EPD, 2003a), EPD routine and ad hoc marine monitoring programmes of 2003/2004 and study reports published by local academia (Zheng et al., 2000 Muller et al., 2002 Tam and Yao, 2002 Wong et al., 2001, 2005). With the exception of mirex and toxaphene, all other POPs pesticides were detected in the... [Pg.329]

Toxic air pollutants are pollutants which are hazardous to human health or the environment but which are not specifically regulated by the CAA. These pollutants are typically carcinogens, mutagens, and teratogens. The CAAA of 1977 failed to result in substantial reductions in the emissions of these harmful substances. [Pg.399]

The Agency s mission is to control and abate pollution in the areas of air, water, solid waste, pesticides, radiation, and toxic substances. The EPA coordinates and supports research and anti-pollution activities by state and local governments, private and public groups, individuals, and educational institutions. [Pg.288]

Although the petrochemical and metals industries were the primai y focus of the toxic air pollutants legislation, approximately forty of these substances have been detected in fossil power plant flue gas. Mercury, which is found in trace amounts in fossil fuels such as coal and oil, is liberated during the combustion process and these emissions may be regulated in the future. EPA issued an Information Collection Request (ICR) that required all coal-fired plants to analyze their feed coal for mercury and chlorine. Since these data will be used in making a regulatory decision on mercury near the end ot the year 2000, it is critical that the power industry provide the most accurate data possible. [Pg.445]

This is the concept that has developed decades ago in connection with toxic substances, food additives, air and water pollution, fire and related environmental concerns, and so on. It can be defined as a level of risk at which a seriously adverse result is highly unlikely to occur but it cannot be proven whether or not there is 100% safety. In these cases, it means living with reasonable assurance of safety and acceptable uncertainty. [Pg.276]

Ash particles produced in coal combustion are controlled by passing the flue gases through electrostatic precipitators. Since most of the mass of particulate matter is removed by these devices, ash received relatively little attention as an air pollutant until it was shown that the concentrations of many toxic species in the ash particles increase as particle size decreases. Particle removal techniques become less efiective as particle size decreases to the 0.1-0.5 pm range, so that particles in this size range that escape contain disproportionately high concentrations of toxic substances. [Pg.129]

In the U.S., there are local, state, and federal laws regulating health, safety, and the environment. The laws that address the area of pollution control also cover health and safety, toxic substances, noise, transportation, and building site approval. [Pg.153]

In general, dilution ventilation alone is inappropriate for highly toxic substances, carcinogens, dusts or fumes or for widely fluctuating levels of pollutants. Since hygiene standards are often revised (usually downwards), specifications of existing systems may prove inadequate. [Pg.274]

The public was outraged. It did not matter whether the pollution came from a chemical factory, power utilities, mines, petroleum, automobiles, or semiconductors the chemical industry s reputation was in free-fall. In 1990, the U.S. Congress established the Super Fund, requiring industry to pay for cleaning up hazardous waste. Major chemical manufacturers banded together in a voluntary effort to reduce factory emissions to almost zero and to police themselves. At the opposite extreme, some environmentalists called for the elimination of all toxic substances. [Pg.199]

EPA has established that hydrogen sulfide is a regulated toxic substance and is a hazardous substance as defined under the Federal Water Pollution Control Act. OSH A has established an acceptable ceiling concentration of 20 parts per million (ppm) for hydrogen sulfide in the workplace, with a maximum level of 50 ppm allowed for 10 minutes maximum duration if no other measurable exposure occurs. NIOSH has set a maximum Recommended Exposure Limit (REL) ceiling value (10 minutes) of 10 ppm. A complete listing of federal and state regulations and recommendations are found in Chapter 7. [Pg.27]

For a limited number of exposure pathways (primarily inhalation of air in the vicinity of sources), pollutant fate and distribution models have been adapted to estimate population exposure. Examples of such models include the SAI and SRI methodologies developed for EPA s Office of Air Quality Planning and Standards (1,2), the NAAQS Exposure Model (3), and the GEMS approach developed for EPA s Office of Toxic Substances (4). In most cases, however, fate model output will serve as an independent input to an exposure estimate. [Pg.295]
