Arsenic is toxic to humans and can affect people of any age or health status. Arsenic levels in the environment can vary by locality, and it is found in water, air, and soil.

Asbestos is a mineral fiber that occurs in rock and soil. Because of its fiber strength and heat resistance, asbestos has been used in many materials produced for building or home construction, particularly if they were manufactured prior to 1980, such as shingles, ceiling and floor tiles, and attic and pipe insulation. If these materials are broken, crushed, or disturbed, the asbestos fibers may be released into the air and become a health hazard. High exposures to asbestos may occur during demolition and rebuilding.

A healthy immune system defends the body against disease and infection. But if the immune system malfunctions, it mistakenly attacks healthy cells, tissues, and organs. Called autoimmune disease, these attacks can affect any part of the body, weakening bodily function and even turning life-threatening

Millions of women and men around the world use cosmetics to enhance or change their appearance. The common term makeup refers to cosmetics such as foundation, eye shadow, eye liner, mascara, blush, and lipstick. Other cosmetics may include nail polish, body wash and moisturizers, perfumes, and hair coloring or styling products.

Drinking water in the U.S. comes from a variety of sources, including public water systems, private wells, or bottled water. Worldwide, nearly 2 billion people drink contaminated water that could be harmful to their health. Though more of a concern in developing countries, safe drinking water is a U.S. public health priority.

Since the mid-twentieth century, electricity has been an essential part of our lives. Electricity powers our appliances, office equipment, and countless other devices that we use to make life safer, easier, and more interesting. Use of electric power is something we take for granted.

Endocrine disruptors are natural or human-made chemicals that may mimic or interfere with the body’s hormones, known as the endocrine system.

No two people live in the exact same environment. The SOIL beneath our feet, the AIR we breathe, and the WATER flowing through our pipes and waterways can all differ greatly, depending on where we live. On top of that, each of us eats different foods, shares our space with different plants and animals, and has access to different medicines and technology. NIEHS explores the connections between the environment and health, gathering scientific knowledge to help prevent human disease.

Flame retardants are various chemicals applied to materials to help prevent burning or slow the spread of fire. The term applies to the function, not a specific composition, of such chemicals.

The Human Health Exposure Analysis Resource (HHEAR) is a centralized network of exposure analysis services and expertise available to eligible researchers who want to add or expand exposure analysis to their studies of human health.

ICE provides data and tools for the development and evaluation of new chemical safety testing methods.

OPERA is a free and open-source quantitative structure-activity relationship (QSAR) tool.

Any amount of lead in the body can harm your health. NIEHS supports research to find out who is affected by lead exposure and the range of health effects caused by lead.

The microbiome is the collection of all microbes, such as bacteria, fungi, viruses, and their genes, that naturally live on and inside our bodies. The microbiome is diverse, and each body site, for example, the gut, skin, and oral and nasal cavities, is home to a community of microbes.

The NIEHS Scholars Connect Program provides opportunities for undergraduate students from underrepresented groups, who are focused on science, technology, engineering, and mathematics (STEM), to connect with the NIEHS community and engage in emerging areas of research, training, and career-oriented activities.

The Summer Internship Program at the National Institute of Environmental Health Sciences (NIEHS) provides an opportunity to spend a summer working at the institute, side by side with some of the leading scientists in the world, in an environment devoted exclusively to environmental health research.

The National Institutes of Health Disaster Research Response (DR2) program leads U.S. efforts and works with global partners to improve capacity for timely research related to disasters and public health emergencies. NIEHS coordinates the program. Disasters and public health emergencies result in unique combinations of human exposures to toxic substances, hazards, and stressors; yet too often, basic questions about the health and safety of communities, responders, and workers affected by these events go unanswered.

Botanical dietary supplements, sometimes called herbals or herbal dietary supplements, are products made from plants.

Chemical Effects in Biological Systems (CEBS), an integrated database of toxicology and toxicogenomics study information and data from NTP, National Institute of Environmental Health Sciences (NIEHS), other government agencies, academia, and pharmaceutical companies.

The NTP Nonneoplastic Lesion Atlas is a new searchable, Web-based resource containing thousands of high-quality images and guidelines for diagnosis of nonneoplastic lesions in experimental rodent models.

Occupational health is a specialty that strives to keep people safe and well in the workplace. Work can affect physical, mental, and social well-being in many ways.

Developing a diverse biomedical workforce is an important part of the NIEHS mission to advance environmental health. To that end, NIEHS supports a wide range of high-quality internships, training, and career development opportunities.

The National Institute of Environmental Health Sciences (NIEHS) is one of 27 institutes and centers of the National Institutes of Health, which is part of the U.S. Department of Health and Human Services. Unlike the majority of NIH institutes located in Bethesda, Maryland, NIEHS is located in Research Triangle Park, North Carolina, a major U.S. center of biotechnology and health research.

Practical Solutions to Protect Human Health and the Environment from Toxic Chemicals

The Report on Carcinogens is a scientific and public health document that identifies substances that pose a cancer hazard for people in the United States. It is intended to help people make informed decisions about their own health.

Reproductive health refers to the condition of female and male reproductive systems during all life stages. NIEHS conducts and funds research to understand how our environment may affect reproductive health.

The National Institute of Environmental Health Sciences Superfund Research Program (SRP) protects people’s health by reducing exposure to harmful things in our environment, improving our understanding of how such exposures affect health, and providing sound science to inform communities and decision-makers.

The Superfund Research Program (SRP) has provided practical, scientific solutions to protect health, the environment, and communities since 1987. SRP works to learn more about ways to protect the public from exposure to hazardous substances, such as industrial solvents, arsenic, lead, and mercury, which can cause death, disease, and birth defects. These and other toxic substances are found in contaminated water, soil, and air at Superfund waste sites throughout the United States.

Systematic review is a method for answering specific research questions. It should not be confused with a regular literature search. It is much more than that. Systematic review uses a predefined, multistep process to identify, select, critically assess, and synthesize evidence from scientific studies to reach a conclusion.

The Toxicology in the 21st Century program, or Tox21, is a unique collaboration between several federal agencies to develop new ways to rapidly test whether chemicals may affect human health.

The Worker Training Program (WTP) provides health and safety training for thousands of workers who may be involved in handling hazardous materials or in responding to emergency releases of hazardous materials. These workers gain new skills on how to safely handle, remove, and contain hazardous waste, such as chemicals, asbestos, radiation, and lead.
