Asbestos is a mineral fiber regulated under a special area of
the Toxic Substances Control Act (TSCA). It has been determined
that breathing high levels of asbestos fibers can lead to an increased
risk of lung cancer. This site includes regulations, guidance,
health information and general information.

- The Baltimore Case Study
The Baltimore Case Study report describes the work and results
of the 3-year air screening pilot project in Baltimore, Maryland.
It illustrates the development and implementation of a new methodology
for evaluating air quality impacts of toxic air pollutant emissions.
The risk screening methodology allowed the partnership to evaluate
potential human health risks from more than 175 chemicals emitted
to the air by more than 125 facilities in and around the partnership
neighborhoods. The case study presents the process used as well
as the results and lessons learned from the experience.
- Expert System (Oncologic)
The Expert System, or Oncologic, is a personal computer
program developed to analyze chemical structures to determine
the likelihood that they may cause cancer.
The Chemical Screening Tool for Exposures and Environmental Releases
(ChemSTEER) is a personal computer-based software program. ChemSTEER
uses established EPA methods to generate screening-level estimates
of environmental releases of and worker exposures to chemicals
manufactured and used in industrial and commercial operations.
The tool also contains data and estimation methods to assess situations
involving many common industrial / commercial sectors (e.g., automotive
refinishing) and chemical functional uses (e.g., surfactant in
hard surface cleaner). ChemSTEER is currently applied in EPA's
New Chemicals Program. In the future, engineers and technical
users may find the tool helpful in assessing exposures and releases
- Community Air Screening How-To Manual
OPPT's Community Community Air Screening How-to Manual makes air
quality assessment tools more accessible to communities. The How-to
Manual presents and explains a step-by-step process that a community
can follow to form partnerships to access technical expertise,
identify and inventory local sources of air pollutants, review
pollutant sources to identify known hazards that may present a
potential health risk to the community and set priorities and
develop plans for improvement.
Health Status Indicators Project
The Community Health Status Indicators (CHSI) Project was launched
in response to grassroots requests from local health officials for
health data at the local level. Community health improvement begins
with an assessment of needs, quantification of vulnerable populations,
and measurement of preventable disease, disability, and death. In
one brief document, local health officials can see, react, and act
upon the data provided.
- Consumer Labeling
CLI is a voluntary, cooperative partnership among federal, state,

pesticides, and household hard surface cleaners. Find out about the
label changes and the implementation of the National Read the Label
FIRST! campaign to encourage the reading of product labels.
- Design for Environment
DfE is a voluntary program that works with industry and other partners
to integrate health and environmental considerations in business decisions.
DfE partnerships compare the risks, performance, and costs of alternative
technologies, and encourage businesses to adopt cleaner technologies
and pollution prevention practices.
The Exposure & Fate Assessment Screening Tool (E-FAST) is a personal
computer based software program. E-FAST is a screening level tool
that estimates human exposure as well as aquatic ecosystem exposure
to and risk from the release of chemicals to the environment.
E-FAST can be used by community groups to estimate exposure and risk
from such areas as industrial/commercial activities and the use and
disposal of consumer products.

(Forum on State and Tribal Toxics Action)
The Environmental Council of the States (ECOS), in cooperation with
the National Tribal Environmental Council (NTEC), and EPA's Office
of Pollution Prevention and Toxics (OPPT) are co-sponsoring the meetings
of the Forum on State and Tribal Toxics Action (FOSTTA). FOSTTA (Forum
on State and Tribal Toxics Action) is a mechanism by which state and
tribal officials jointly, and in cooperation with EPA, address toxics-related
issues. The Forum is designed to foster and improve communication
and coordination among states, tribes, and EPA.
- Internet Geographical Exposure
Modeling System/Chemical Safety Mapper (IGEMS/CSM)
The new GEMS is a modernization of OPPT's older Graphical Exposure Modeling System and PCGEMS tools.
GEMS brings together in one system several EPA environmental fate and transport models and the
environmental data needed to run them. GEMS includes models and data for ambient air, surface water,
soil, and ground water, and makes the models much easier to use than their stand-alone counterparts.
The GEMS models estimate environmental concentrations that can be used by communities or environmental
groups in exposure and risk assessments for local populations.
With enhanced GIS capability, the IGEMS/CSM models estimate environmental concentrations that
can be used by communities or environmental groups in exposure and risk assessments for local populations.

references available for interlibrary loan.
- Risk Screening Environmental
The RSEI model is a personal computer-based, priority setting, screening-level
tool that evaluates the hazard and relative risk-related impacts of
toxic chemical releases and transfers from industrial facilities.
RSEI integrates information on the amount of chemicals released to
the environment, the relative long-term toxicity of these chemicals
to people outside the workplace, the degree to which people are potentially
exposed, and the estimated size of the exposed population.
Communities can use RSEI, in a comparative fashion, to quickly focus
on certain sources of risk that warrant further investigation. The
model's pounds-based, hazard-based and risk-related perspectives can
be used to examine trends, to rank and prioritize chemicals and industry
sectors for strategic planning, to conduct risk-related targeting,
and to help investigate environmental justice issues.

This is a searchable, PC-based database of scientific studies on the
health and environmental effects of toxic chemicals related to Section
8(e) of TSCA, which states that manufacturers, importers, and distributors
of chemical substances and mixtures are required to inform EPA of
studies that reasonably support the conclusion that the chemicals
present a "substantial risk of injury" to human health or the environment.
It provides users with information about these studies and serves
as a pointer system to the complete studies.
