Drink Only Distilled Water

Water pollution is a large set of adverse effects upon water bodies (lakes, rivers, oceans, groundwater) caused by human activities. It is a serious problem in the global context. It has been suggested that it is the leading worldwide cause of death and disease, and that it accounts for the deaths of more than 14,000 people daily. Drinking water currently available around the world is severely carcinogenic.

Principal sources of water pollution are:

1. Industrial discharge of chemical wastes and byproducts
2. Discharge of poorly-treated or untreated sewage
3. Surface runoff containing pesticides
4. Slash and burn farming practice, which is often an element within shifting cultivation agricultural systems
5. Surface runoff containing spilled petroleum products
6. Surface runoff from construction sites, farms, or paved and other impervious surfaces e.g. silt
7. Discharge of contaminated and/or heated water used for industrial processes
8. Acid rain caused by industrial discharge of sulfur dioxide (by burning high-sulfur fossil fuels)
9. Excess nutrients added by runoff containing detergents or fertilizers
10. Underground storage tank leakage, leading to soil contamination, thence aquifer contamination.

Contaminants may include organic and inorganic substances.

Some organic water pollutants are:
1. Insecticides and herbicides, a huge range of organohalide and other chemicals
2. Bacteria, often is from sewage or livestock operations;
3. Food processing waste, including pathogens
4. Tree and brush debris from logging operations

Some inorganic water pollutants include:
1. Heavy metals including acid mine drainage
2. Acidity caused by industrial discharges (especially sulfur dioxide from power plants)
3. Chemical waste as industrial byproducts
4. Fertilizers, in runoff from agriculture including nitrates and phosphates
5. Silt in surface runoff from construction sites, logging, slash and burn practices or land clearing

The Pain In Paint

Paints, the world over, are toxic. Some effects from the toxic ingredients of paints include:

1. Depression of the central nervous system,
2. Headaches,
3. Nausea and giddiness,
4. Irritation to the skin, eyes, and respiratory track,
5. Asthma, anaemia and bronchitis.

In 1989 the World Health Organisation reported that painting as an occupation was carcinogenic. Painters suffered from lung cancer 40% above the average and their children, too, were more prone to cancer.

In the indoor environment of buildings there is off-gassing from ingredients used in building materials, paints and furniture, and also from equipment. This may result in poor indoor air quality, particularly in a well insulated building where the drafts have been eradicated. The effect on the people using the building may be lowered vitality, more asthma and respiratory illnesses, headaches, and other symptoms of what has now come to be known as Sick Building Syndrome.

Both the production and use of paint/finishes can lead to major environmental problems. One tonne of paint can produce as much as thirty tonnes of solid waste, much of which is not degradable. Some paints may also contain heavy metals such as cadmium (a substance highly toxic to the heart, kidneys and liver and used particularly in yellow, orange & red pigments), and titanium. These often get discharged from factories into rivers and estuaries. It is estimated that over 10 million tons a year of paint are used world wide on buildings.

Volatile organic compounds (VOC's) are used by the major paint manufacturers as solvents, they evaporate very readily, entering your body through breathing the fumes, when painting and the water supply through washing out brushes and pouring the waste down the drain. VOC's react in the atmosphere leading to the formation of smog containing secondary pollutants like ground-level ozone and peroxyacetyl nitrate. Many paints and treatments also include fungicides, added to them in order to prevent mould. These include tributyl tin (listed as 'highly hazardous' by the World Health Organisation), carbamates & permethrin should all be avoided.

Synthetic paints are combustible and can catch and spread fire readily from one area to the next, giving off clouds of highly toxic smoke that can asphyxiate a victim very quickly. This extra fire intensity and spread, and heavy toxic smoke, makes it very dangerous for rescuers and fire fighters.

In America where there are a lot of timber frame houses, and even masonry structures with wood stud/gypsum interiors, little time is left for escape and the structure is generally completely consumed by the fire. Major old structures, mostly built out of stone, are still subject to quick flame spread, heavy toxic smoke, and high heat when painted with synthetic products. Although more of the structure would be standing, due to its stone/masonry construction, the interior would most likely be destroyed.
