Acetone, a colorless liquid also known as Propanone, is a solvent used in manufacture of plastics and other industrial products. Acetone may also be used to a limited extent in household products, including cosmetics and personal care products, where its most frequent application would be in the formulation of nail polish removers. Breathing moderate-to-high levels of acetone for short periods of time, however, can cause nose, throat, lung, and eye irritation; headaches; light-headedness; confusion; increased pulse rate; effects on blood; nausea; vomiting; unconsciousness and possibly coma; and shortening of the menstrual cycle in women.
Airborne disease can spread when people with certain infections cough, sneeze, or talk, spewing nasal and throat secretions into the air.
A mixture of solid particles and liquid droplets found in the air, ranging in size, origin and consequence. Particles less than 2.5 micrometers in diameter, also known as fine particles or PM2.5, pose the greatest risk to health
Antimicrobials are chemicals added to products to kill or inhibit the growth of microbes. They are also called antibacterials or biocides.
Asbestos is a mineral fiber that occurs in rock and soil. All types of asbestos cause lung cancer, mesothelioma, cancer of the larynx and ovary, and asbestosis (fibrosis of the lungs). Exposure to asbestos occurs through inhalation of fibres in air in the working environment, ambient air in the vicinity of point sources such as factories handling asbestos, or indoor air in housing and buildings containing friable (crumbly) asbestos materials.
Bisphenols are chemicals used to harden plastic; Phthalates are chemicals used to make plastic more flexible and to make fragrances last longer. Exposure to bisphenols and phthalates can be harmful, especially forfetuses and young children. They can mimic or block hormones — the chemical messengers that help our bodies function properly — causing health problems.
Infectious diseases caused by microorganisms such as bacteria, viruses, parasites and fungi that can be spread, directly or indirectly, from one person to another.
Eave is part of the roof that extends out beyond the exterior wall.
An elevation is a view from the side of an object, when drawing interior elevations, this would represent one of the walls. This would include any windows or doors as well as any built-in furniture that is in direct contact with the wall.
Refers to the constant presence and/or usual prevalence of a disease or infectious agent in a population within a geographic area.
Environmental diseases are determined by environmental factors that can be related to the personal lifestyle (smoking, alcohol/substance abuse, abnormal eating patterns), physical factors from the environment (UV radiation, cold, heat, air pressure, electricity), or exposure the irritant or toxic chemicals from the environment (heavy metals, halogens, organic compounds, or noxious gases).
Ethylene glycol is a colorless, syrupy liquid. It is used as an antifreeze, in making polyester plastics, and for some manufacturing. It can harm the eyes, skin, kidneys, and respiratory system. Ethylene glycol can cause death if swallowed.
Spread of microorganisms from the infected stool of one person into the mouth of another; may occur via fecal contamination of food or water supply, or by hand-to-mouth transmission following inadequate handwashing after touching contaminated items.
Formaldehyde is a colorless, highly toxic, and flammable gas at room temperature. It is used in the production of fertilizer, paper, plywood, and some resins. It is also used as a food preservative and in household products, such as antiseptics, medicines, and cosmetics. Exposure to formaldehyde can irritate the skin, throat, lungs, and eyes. Repeated exposure to formaldehyde can possibly lead to cancer.
Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity.
Hygiene refers to behaviors that can improve cleanliness and lead to good health, such as frequent hand washing, face washing, and bathing with soap and water.
Indoor air pollution refers to chemical, biological and physical contamination of indoor air. It may result in adverse health effects.
Infectious diseases are diseases caused by microorganisms. These are microscopic organisms, such as bacteria, viruses, fungi, or parasites. They can sometimes be caught from other people, the environment, from animal contact, or from insect bites.
Methylene chloride, also known as dichloromethane or DCM, is a solvent used in a range of products. The average consumer is most likely to encounter it in paint strippers, even though safer alternatives exist. Methylene chloride has been linked to cancer, cognitive impairment, and asphyxiation.
Morbidity is the state of being symptomatic or unhealthy for a disease or condition. It is usually represented or estimated using prevalence or incidence.
In medicine, a term is used for death rate, or the number of deaths in a certain group of people in a certain period of time. Mortality may be reported for people who have a certain disease, live in one area of the country, or who are of a certain gender, age, or ethnic group.
Neglected Tropical Diseases (NTDs) are a group of parasitic and bacterial diseases that cause substantial illness for more than one billion people globally. Affecting the world’s poorest people, NTDs impair physical and cognitive development, contribute to mother and child illness and death, make it difficult to farm or earn a living, and limit productivity in the workplace.
A non-communicable disease is a noninfectious health condition that cannot be spread from person to person. It also lasts for a long period of time. This is also known as a chronic disease.
Overcrowding occurs if there are more than three people per habitable room; it can be measured as the average living area per person in the place of residence.
Perchloroethylene, also known as perc, is a colorless, nonflammable liquid solvent with a sweet, ether-like odor. It is primarily used in industrial settings and also for dry-cleaning fabrics and degreasing metals. During dry cleaning, perc primarily enters the body from inhalation of the vapors, potentially resulting in the following health hazards: dizziness, drowsiness, and loss of coordination; mild loss of memory, visual perception, and reaction time after several years of exposure; or redness and blistering of the skin after prolonged dermal contact.
“PFAS” is short for Per- and Polyfluoroalkyl Substances. PFAS don’t easily break down, and they can persist in your body and in the environment for decades. As a result of their pervasiveness, more than 95 percent of the U.S. population has PFAS in their bodies, according to the Centers for Disease Control and Prevention (CDC).
