Common household toxic chemicals

More than 80,000 chemicals are used regularly in our society, but only a few hundred have been studied for their health effects and regulated. Many of those studied are toxic chemical hazards.

Do you think that we are safe at home??? Actually, we have been already exposed with a lots of toxic chemicals which can effect for our health!!!! bad….Here's a list of the seven most common toxic chemicals found in our home.


Health Effects*

Common Exposure Sources

Bisphenol A (BPA)

Birth defects; hormone disruptor

Polycarbonate plastic; canned foods and beverages


Toxic to brain and nervous system; decreased IQ; aggression and hyperactivity disorders

Lead based paint; household dust; outdoor soils; consumer products


Toxic to brain and nervous system

Consumption of contaminated fish and shellfish


Interferes with iodine uptake of thyroid gland, which regulates hormones necessary for proper development

Drinking water; consumption of irrigated crops; milk


Hormone disruptor; birth defects; reproductive disease; reduced sperm counts; heart disease; diabetes

Polyvinyl chloride plastic; household cleaners and other products with synthetic fragrance; cosmetics; food packaging

Polybrominated diphenyl ethers (PBDEs)

Interfere with brain development and may be linked to hyperactivity; toxic to reproductive system

Flame retardants used in electronics, polyurethane foam in upholstered furniture and mattresses, black out drapes and textiles that off-gas and can be found in household dust and food


Toxic to liver; disrupts thyroid hormone system (necessary for development); may cause cancer

Antibacterial agent used in liquid soap, beauty products and cleaning products

Based on animal and/or human studies.

Acute and chronic effects


Pollutants can have acute effects. An acute effect is one that occurs soon after exposure, usually to large amounts of pollutant. It is really apparent because organisms response to the toxin shortly after being exposed. For example, a person exposed all at once to a high dose of radiation may be killed by radiation sickness soon after exposure. A chronic effect takes place over a long period, often as a result of exposure to low levels of a pollutant. It is much more difficult to determine because the effect may not be seen for years. However, that same total dose, received slowly in small amounts over an entire lifetime, may instead cause mutations and lead to disease or affect the person’s DNA and offspring.


Another example of chronic toxicity involves lead. Lead was used in paints, gasoline, and pottery glazes for many years, but researchers discovered that it has harmful effects. the chronic effect on the nervous system are most noticeable in children, particularly when children eat paint chips.

We also describe long lasting exposure as chronic, although their effects may or may not persist after the toxin is removed. It usually is difficult to access the specific health risks of chronic exposure because other factors, such as aging or normal disease, act simultaneously with the factor under study.

DO U KNOW?????

An acute exposure may make an organism ill but not kill it, while chronic exposure to a toxic material may cause death. A good example of this is alcohol toxicity too. Consuming moderate accounts may result in ilness (acute toxicity & full recovery). Consuming moderate amounts over a number of year may result in liver damage and death (chronic toxicity and death).
