Domestic pollution


We talk very often in the media about external pollution.
But domestic pollution is a subject that is not addressed and is quite unknown to the public. or each of us stays on average 14 hours a day either at his home or inside the building.

The definition of domestic pollution, you will have understood it, it can no longer be clear: it designates all harmful substances to which one exposes himself or, more broadly, in closed premises (work and leisure places, public spaces, etc.)


Main sources of domestic pollution

1 - Our house equipment and combustion appliances (gas boiler, fireplace, stove, etc.). these devices can produce carbon monoxide, nitrogen dioxide or ozone
2 - Our daily activities and habits in the home: smoking, use of household products, presence of pets, DIY work, lack of ventilation at the origin of mold development etc.
3 - The materials that were used for the insulation or construction of the building and the components of our furniture and equipment. they may contain or emit formaldehyde, lead, volatile organic compounds (cov,) mineral fibers etc.

Some polluting substances can be found in higher concentrations inside your home than outside.


3 categories of domestic pollutants

1 - On pollutants biological Molds, mites, pets.

2 - On pollutants physical Natural or artificial mineral fibres, gas (e.g. radon,) certain metals (plomb).

3 - On pollutants chemicals : carbon monoxide, volatile organic compounds or cov (formaldehyde, benzene, phthalates etc.). nitrogen oxide, particles, pesticides, tobacco smoke, polycholorobiphenyl (pcb,) etc.


Zoom on main domestic pollutants

The main domestic pollutants are tobacco smoke, lead, mineral fibres, nitrogen oxides, particles, allergens, molds, volatile organic compounds (cov) including glycol ethers.

1 - tobacco smoke


It contains up to 4,000 toxic substances. it is carcinogenic, for the smoker but also for its surroundings which is exposed to smoke. It's called passive smoking. In addition to toxic compounds, tobacco releases during its combustion of carbon monoxide and irritating substances. if the smoker remains the most exposed, his entourage also inhales these smokes. the health consequences are numerous: cardiovascular diseases, degradation or destruction of organs constituting the respiratory tract, inflammatory diseases of the intestine, risk of ulcer and other diseases of the digestive system, premature aging of the skin, declining fertility, risk of sudden death is increased in infants, infections of bronchial , nose, throat and ears of children who are more.

2 – Lead


Lead exposure is the cause of saturnism in children and adults. Saturnism is characterized by a set of physical, neurological and/or mental disorders whose severity increases with the importance of exposure.

But where do we find lead in our houses ?
Particularly in the paintings of the former dwellings. Before 1948, the paintings contained lead. it is estimated that approximately 10 million housing units are affected. with the time or occasion of work, paint dust is released.
The presence of lead can also be found in water when it passes through lead pipes. it then takes care of microparticles and it intoxicates those who consume it. lead was very used for inland pipes until the 1950s, and for public pipes until the 1960s. its use then reduced much. It has been banned since 1995. the replacement of existing lead pipes is planned by the end of 2013, for both internal and public network pipelines.
You can also find lead: within the framework of your work (even if the professions exposed are regulated by the labor code: renovation / destruction companies, foundries, metal recovery, etc.).
Once absorbed, lead will be stored by the body. a part is eliminated (mostly by urine), but in much smaller amounts in children than in adults.
If exposure continues, lead concentrations in the organism increase and may have effects over several years, including delay.

3 – Silicous artificial mineral fibresform
Thanks to their very good results in terms of acoustic insulation, phonic and heat resistance, these fibers are used in many materials and products. Today we know that these substances are known to be carcinogens for some (asbestos, dairy wool) or highly suspected. The use of asbestos is thus prohibited in france since 1 January 1997. caution is for other types of mineral fibers, in the absence of sufficient data. glass and rock wools were classified by oms as possible carcinogens and, after modifications made by manufacturers, reclassified as "unclassifiable" in 2001.
These fibers can include insulation wools: glass wool, rock wool, dairy wool. natural (asbestos) or artificial, mineral fibres can be hazardous to health if inhaled: as they are often very thin, they penetrate deep into the lungs or migrate to other organs, because the body is unable to eliminate them. They are responsible for lung disease (fibrosis) and respiratory insufficiency, weeping plates and lung and plare cancers (mesothelioma).
Mineral fibres are also very irritating to the skin, eyes and respiratory system.

4 – Nitrogen oxides
formWe find monoxide or nitrogen dioxide in our accommodation. Nitrogen monoxide (no) is produced by high temperature combustions. When it is present in our houses, it can therefore come from industrial activities nearby, motor traffic, gas-operated appliances (kitchen, water heater, gas stove,) wood burning heating appliances (roadway, insert, etc) or gasoline as well as radiators, tobacco smoke. Nitrogen dioxide (no2) when it results from oxidation of nitrogen monoxide.
Health risks: nitrogen oxides can trigger crises in asthmatic people. they can also cause respiratory disorders: irritations, feeling of oppression, cough, discomfort.
An impaired combustion device can also emit carbon monoxide, an odourless and toxic gas that causes nearly 200 deaths each year. it causes headaches and nausea at low doses. as it replaces oxygen in the blood, if exposed to a significant dose of carbon monoxide, there is a risk of loss of knowledge, coma and death by asphyxia.

5 – particles :form These are small organic or mineral substances present in suspension in ambient air. they are classified according to their size: particles, fine particles and ultrafine particles (nanoparticles). the smaller they are, the deeper they penetrate the lungs, and the more they can be harmful. they can come from external pollution sources such as road traffic (diesel vehicles without particulate filter) or industrial activities (incinerator, foundry). They may also be related to domestic activities (household, DIY) or individual behaviours (smoking, wood heating). they can be solid or liquid.
Risks in children: promotes respiratory diseases, especially in babies under 12 months of age, hinders the proper development of lung functions, triggers asthma attacks and may aggravate the disease, is causing coughs, bronchitis, etc.
Risks in adults: fine and ultrafine particles increase mortality from cardiovascular, respiratory or lung cancer.

6 – allergens
formIt is estimated that about 1 in 4 French is allergic. sources are numerous: domestic animals, cockroaches, molds, mites. the effects of exposure to allergens can be accentuated by the irritating power of the following factors: household products: soil washing, dusting for furniture, etc. odour diffusers, scented candles, incense, essential oils, volatile organic compounds (cov) released by furniture, floor coverings, etc. cosmetic products used in sprays, tobacco: this is the worst of the internal pollutants.
Allergic manifestations can have a significant impact on everyday life: lack of sleep, permanent fatigue, irritability, consequences on professional activities, leisure, school activity, etc.

7 – mouldingform
It is microscopic mushrooms that develop thanks to the combination heat + humidity. For this reason, they will often be found in bathrooms, kitchens, laundry rooms, cellars, etc.
Molds release spores and/or deodorant substances in ambient air. These spores are inhaled and can be at the origin of: allergic reactions, irritation of the eyes, of the throat, of the nose, of respiratory disorders: cough, whistling breathing, respiratory discomfort, lung infections (especially in fragile people) of skin infections.

8 – Volatile organic compounds (cov)
formIt is chemical substances that are volatile at room temperature. these products can be found for years in homes. We find them in the composition of many products and equipment of our houses. They are very present in our domestic environment: varnish, paints, lacquers, parquet floors, plywood furniture, cleaning and maintenance products, solvents, etc. 80% of homes have a formaldehyde content 5 to 50 times higher than that of the outside.
Among volatile organic compounds (cov) include benzene, stylene, toluene, trichloroethylene, formaldehyde, glycol ethers. and the list is far from exhaustive!
Their health effects are not yet all well known, but some volatile organic compounds (Cov) are classified as certain or probable carcinogens. observed effects: skin irritation and mucous membranes (eyes, nose, throat,) nausea and headaches, irritations and respiratory system disorders.

9 – household insecticides: pesticides also contaminate the air of housing !
Those responsible are: insecticides, puff, chips, cockroaches, pest control for dogs, cats, wood products.


Possible prevention

1 - tobacco smoke: Quit smoking in the accommodation and you get to the maximum if it is not possible (this will minimize but will not delete them however)

2 - Lead: replacement of pipes if leaded, removal of old paints, do not use kitchen utensils that may contain lead in a professional environment: use adequate protective devices

3 – artificial mineral fibres: avoid drilling, sanding or breaking materials containing asbestos or artificial mineral fibres without being equipped with adequate protections: wearing a mask suitable for the retention of fine elements and gloves. humidify fibre-cement supports to limit emissions of dust when depositing or acting and not treat these materials with high pressure cleaners for example. wastes of products that may contain asbestos should be deposited in a dock that collects this type of waste.

4 – Nitrogen oxides: Very regular aeration of housing to reduce concentrations in indoor pollutants. Consider controlling the operation of domestic combustion appliances, including heating appliances.

5 – particles: Regularly air the housing. for the most sensitive or fragile people, lightly wet linens can be used to make dust and thus trap as much as possible particles without scattering them in the ambient air. vacuum cleaners with a particulate filter will also yield good results.

6 – allergens: reduce exposure to substances you are allergic to.

7 – moulds: Control room temperature and humidity and aerate and ventilate to evacuate excess moisture and condensation.

8 - Cov: Once again, do not hesitate to make a good ventilation and ventilation of the accommodation. on the other hand, additional precautions are used to limit the risks: respect the precautions of use given by manufacturers of maintenance or DIY products, use only the necessary quantities every time, beware of products toxic substances, , corrosive and flammable (pictograms,), do not mix products, do not store products more than necessary, after dry cleaning in a dry cleaner, take care ofaerating clothing before you wear it or store it, limit the use of interior deodorisers. inform you about their possible chemical emissions (les labels indicate levels of pollutant emissions) The European eco-label, or the Blue Angel, are interesting indicators. favor products without emissions or with the lowest emission level, such as the products you will find at home Penntybio.

9 – household insecticides: without hesitation, turn to insecticide products that we market at Penntybio.

In the ideal : preferred biologics products overloaded with solvents, for painting or maintenance products. Today there is a wide range of natural products that can be suitable for all domestic uses of the individual as well as professional: paints, anti-rolls, lasures, lacquers, oils and maintenance products, vitrifiers, waxes, coatings and wall primers, adhesives, mastics, siccatives, decapants. these products not derived from petrochemicals and guaranteed without heavy metals, exist for different supports (minerals, plaster, wood, iron). and it is enough to add colored pigments adapted to get all the desired color shades.
Also turn to the depollutant interior plants. some of them have the capacity to absorb toxic gases or pollutants. these plants capture pollutants and release oxygen in the house. There are many, the best known being cactus, azalea and boston fern.


Special cases of laundry and maintenance products


We have seen it, a large number of products can cause allergies: dish, laundry, glass products, deodorisers, dust, insecticides, weeding, fertilizer, glues, varnish, cleaners, paints, acrylic resins, etc.

Nowadays, the skins are damaged by repeated contacts with laundry still impregnated with detergent and softening, because it was impossible to rinse properly (water saving requires). These detergents do their work, they destroy fat. despite repeated washing, there are always detergent residues that remain in the clothes after the laundry.

The problem is that our skin protects itself from a grease film, destroying it is weakening our skin. Many of us will support this aggression very well because their skin is solid and is not likely to be attacked by the environment.

In several powdered laundry, we find nta, nitrolotriacetic acid, which has carcinogenic effects on rats and laboratory mice.
Unlike some brands, our maintenance products do not contain synthetic tensio-active, enzyme, or coloring, thus helping to minimize any risk of allergy.

You will find detergents on our site. guaranteed without petrochemical but whose efficiency is at least equivalent or better !


Oil derivatives


The vast majority of toiletries made are made with synthetic products, perfumes and petroleum derivatives. this is one of the reasons why a lot of people suffer fromallergies or skin problems such as'irritation, eczema and psoriasis.
There is often the "Paraben"and its derivatives used as a conservative that has a significant allergic potential.

Our skin is not hermetic, it looks like a sponge and absorbs everything. too many people still know that the products they apply to the skin can have consequences on their health.
Some studies have shown that oil-derived ingredients such as sodium lauryl sulfate have carcinogenic effects. before using a product every day and even several times a day, ask yourself the question.

Even if many people are now paying attention to what they eat, it is essential that they become as conscious as soaps, toothpastes, shampoos and anti-sudorifics they buy also have long-term impacts on their health.


Laundry and environment

lavandeThat laundry washs our clothes, that's the least thing. but did you know that at the end of the program, every machine rejects in the sewer the dirt of the linen and the laundry ?
And that dirty water necessarily ends somewhere. in the best case, these waters are treated in a treatment plant; Most often they join surface waters and their polluting load disrupts aquatic ecosystems.
All residues of laundry are not toxic, but they are dumped in quantities such as they contribute to severe pollution.

Rather disturbing conclusion: the new products that make up the laundry are not completely digested by the purification plants. There is therefore a part of these chemicals that flow into rivers and lakes. but, at the bottom, what are the components that give the laundry its washing power:
  • - Tensio-active (or, more simply said, detergents): they are responsible for cleaning. They are therefore indispensable in a laundry.
  • - Enzymes: they have the function of getting stains out of blood, cocoa, or egg. they cut the dirt molecules into small pieces, making it easier to dissolve in water.
  • - Softeners water attacks the limestone to prevent it from dropping on the linen.
  • - The perfume, natural or synthetic.
  • - Llaundering agents, which eliminate the spots of coffee, tea or fruit making them invisible. The problem is that they tend to attack also the colors of the clothes.
  • - if your clothes look whiter than white, it's the magic effect of optical azuring : they have the power to reflect ultraviolet rays.
  • - Anti-repositioning agents : they work hard to prevent dirt, once extracted from the linen, from resting.
  • - Anti-disintegration : as their name suggests, they avoid that the coloured garments do not deterate too much on others.
  • - finally the revitalizing : thanks to the film it deposits on the fibers, your linen seems soft. innocent at first, all of these agents may not be as white as they look.At the moment, we don't know exactly what these chemicals can pose as a risk to the environment. And when we know what fight it took to get the phosphate ban, there's something to be worried about.
