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.

Asthma is a chronic lung disease with symptoms of coughing, wheezing, chest tightness, or shortness of breath. During an asthma attack, the sides of the airways in the lungs swell and the airways shrink, making it harder to breathe.

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

NIEHS research leads to discoveries about how the environment affects children’s health, which, in turn, become a basis for ways to reduce or stop harmful exposures. Because children are smaller than adults, their risk for harm is greater when exposed to harmful environmental factors. They are more vulnerable to toxic effects because their brains and other organs are still developing.

This network of collaborative centers translates key research findings into clinical and public health practice. Research translation products are intended to help protect and improve children’s environmental health and to promote health equity.

Millions of women and men around the world use cosmetics to enhance or change their appearance.

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.

Research supported by NIEHS shows that protecting lung health requires strategies to improve our environment and lifestyle choices.

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.

Molds can be found everywhere and we encounter them every day. Spores and fragments of these microorganisms can get into the air we breathe.

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.
