Health Impact of Common Paints Article
You may not know that most paints and finishes are made from chemicals that are toxic and irritating to humans and animals. Here are just a few:
Volatile Organic Compounds (VOC's):
These substances readily release vapours at room temperature for years after application. Examples of VOC's are xylene, epoxy, toluene, and ketones.
Acrylics, insecticides, fungicides, synthetic rubber, formaldehyde
Known irritants and possible carcinogens that off-gas indefinitely.
The Environmental Protection Agency from the USA reports that the above substances
cause eye, nose, and throat irritation; headaches, loss of coordination, nausea;
damage to the liver, kidney, and the central nervous system.
It has been found
that average indoor air is 10 times more polluted than the air outside. When
you combine this with the fact that people are spending more time inside than
ever (~90%!) you realise what a problem this is.
Professional painters are a
key risk group, as they are often occupationally exposed to solvents over prolonged
periods.
According to a report by The World Health Organisation: International
Agency for Research on Cancer, there is a link between working as a professional
painter and an increased risk of cancer of up to 20%, with the increased risk
of lung cancer 40%. Other notable risk groups are small children and the elderly.
Many recent studies have shown a connection between the alarming rise in respiratory
ailments amongst young children such as asthma over the last 10-15 years and
pollutant presence in indoor air.

Environmental Impact of Common Paints
Most common paint ingredients come from
petrochemicals: including solvents, fillers, pigments, and drying agents.
The paint production process results in large amounts of toxic waste - up to
10 cans of waste for each can of paint produced.
VOC's released from paint
production and use are hazardous environmental pollutants, responsible for smog
amounts nearly as large as those created by all automobile exhaust.
What are the Alternatives?
The best alternatives are natural and mineral paints,
or traditional limewashes. The raw ingredients of natural paints are primarily
agricultural origin and hence are renewable and reduce Carbon emissions. They
are safer to transport and are readily biodegradable. The manufacturing process
produces no hazardous waste products. In fact, the by-products of manufacture
are composted. The clean up from a painting job can be tipped safely into the
garden. They still contain VOC's but in low concentrations that are within recommended
safety limits.
Mineral paints are completely non-toxic, with no VOC's, and are
also the most durable paints on the market today. This means that they are the
healthiest paints available and they are also technically the best in terms of
performance.
