Canadians are the second largest in the world in terms of the per capita water consumption (1), Canadian households using an average of 360 litres of water per day (2). Water is used in all sectors of society - industry, agriculture, transport, energy, entertainment - as well as municipalities, and must undergo a certain treatment before being used, and released into rivers. Water is used in all sectors of society - industry, agriculture, transport, energy, entertainment - as well as municipalities, and must undergo a certain treatment before being used, and released into rivers. In this paper we examine the issues relating to the use of municipal water consumption, waste water treatment, price and security of supply. In this paper we examine the issues relating to the use of municipal water consumption, waste water treatment, price and security of supply.
Canada has about 9 p. 100 of the global annual renewable freshwater (3), but more than half of Canada's waters flow north, ie away from population centres and industry, which leaves that restricted supply in some parts of the south.

 Lintoxication by pesticides is a serious problem that affects the health of fawn disproportionate infants and children according to the United Nations report released this week Genve which aims to provide information to facilitate awareness and take action concrtes. The number of children by the phnomne concerns is not known but on the basis of experience of many countries, it is certainly important. The report highlights both the lampleur problem that the need to accrotre efforts to better reach and support rural dsavantages the most affected.
Pesticide poisoning
According to the report, it is estimated that the annual number of pesticide poisonings is between 1 and 5 million, of which several thousand deaths.
The report adds that most of poisoning in rural areas of countries dveloppement o protective measures are often inadquates or lacking altogether. The dveloppement countries that use only 25% of pesticide products in the world, registering 99% of this type due dcs dintoxication.Lenfant is a risk exhibitions lev more because it can be more sensitive or more than ladulte exhibitions. The behavior of children, which seeks to play and ignore the danger, entrane an increased risk exposure. In addition, malnutrition and dshydratation increase sensitivity to pesticides and currently approximately 200 million children are malnourished.
Lintoxication by pesticides is a breathing, drinking or eating, or through the skin or mucous membranes. The symptmes may range from fatigue and dizziness, loss dquilibre, nauses and vomiting or even respiratory and neurological effects fatal. Chronic exposure and even at low pesticide binds cancer, malformations in the new-n and lsions nervous and endocrine system.
Sources exposure
The rgime food can be a major source exposure for children. As they grow, children drink and eat proportionately more than ladulte. The pesticide residues in water and food products can therefore be a source of chronic exposure low or greater.Growing food on contaminated soil or local media, and use contaminates water for irrigating fields or washing products constitute a particular risk to the people and especially for children.

Introduction
The Existing Substances Division (ESD) was established in February 2000 to fill the term very extended on the evaluation of chemicals and other substances in Canada under the revised version of the Canadian Environmental Protection (CEPA). The Division is responsible for identifying and assessing the risks that substances (chemicals) existing in Canada pose to human health, including the approximately 23000 substances identified by the Domestic Substances List (DSL) under CEPA.
Canada is the only country in the world that uses a comprehensive approach of this kind to examine all substances commercially available CEPA Environmental Registry.
CEPA provides a framework for the identification and prioritization of existing substances for the purposes of risk assessment and control or management of those considered to pose a risk to human health or the environment. This framework is comprehensive and based on evidence. It takes into account the aspects (exhibition properties, effects) of a given substance in relation to risk it is likely to raise, in addition to being open, transparent and build on the work done in other forums .
There are four ways to determine the sub-stances subject to a risk assessment:
Categorization of listed substances inside.
Review of the decisions taken by other bodies.
Submitting requests directly to the Minister of the Environment.
Providing advice to Ministers of Health and Environment by advisory committees of experts. The requirements of CEPA on the renewed rate-uation existing substances are greatly expanded. Thus, we must now systematically take into account the 23000 listed substances inside. These requirements include the addition of a mechanism for the consideration faster substances, whereas previously we put emphasis on a limited number of existing substances deemed to be of priority interest. The status of this report will be studied during the next parliamentary review of CEPA scheduled for 2007.
In addition to the requirement to establish permanent and evaluate lists of priority substances, CEPA-door a requirement that Ministers of Health and Environment to conduct the categorization of all substances on the list of interior by September 2006 and then to undertake the screening assessments and thorough action, as appropriate. Canada is the first country to adopt this legislative requirement for the use of an iterative and systematic approach for establishing priorities for risk management on all existing substances, although at least one other instance (Commission European 2003) has developed legislative proposals with the same sight. This requirement stems partly from the introduction of previous systematic study of all new chemicals (those not used in Canada from 1984 to 1986) under CEPA 1988 and other similar laws country. This requirement extends further in a logical way the experience gained during the selection of the second list of priority substances, which is partly based on the establish-ment of systematic priorities for a sub-set of much broader some 600 substances.
Under CEPA, all substances on the list must be categorized interior by September 2007 (figure 2) to determine those which:
Be present for individuals in Canada the greatest potential for exposure.
Or are persistent and bioaccumulative or are inherently toxic to humans or organisms other than humans.
Categorization, pre-assessment and evaluation of priority interest dessubstances listed interior
Categorization, pre-assessment and evaluation of priority interest desistance listed interior
Health Canada is responsible for determining what are the substances that "the greatest potential for exhibition and those of inherently toxic to humans. Environment Canada (EC) is responsible for determining what are the listed substances that are persistent internal or bioaccumulative and show intrinsic toxicity for organizations other than humans.

It appears that most commentators have been disoriented by the effects of radio active depleted uranium, leaving just its chemical properties. But the projectiles made thus break, volatilize and / or ignite on impact, resulting dispersion in the atmosphere, sometimes in the form of an aerosol of fine dust of the metal and its oxides. These particles, downward-cover objects and soil. After re-suspension of air (airborne) fortuitous, they can be inhaled or dilutees, days, weeks or even months and years later. There is therefore no need to be inside or close to a tank when it is achieved for risk of absorbing these hazardous materials. |

In Naples, household waste piled in the streets. The reader compassionate judge by the pictures that it is urgent to help the people tormented. Switzerland offers its helping hand to "manage the crisis." It proposes to take charge of waste to burn in our power incineration whose capacity is not fully utilized. That seems quite plausible. But part of this waste is highly toxic and radioactive. No other regions of Italy does take charge of such waste, there are riots against exports, for example in the direction of Sardinia.
The import of such waste has a huge danger. Heavy metals in sewage sludge, waste and radioactive hospital infection should not be burnt in central incinerator. Today, nobody knows with certainty what kind of industrial or other wastes were buried and deposited in landfills located on the outskirts of Naples during the past 20 years.
It can not even be sure that there is no "gifts" American mixed with the waste, as a result of the work of clearing undertaken in certain parts of Kosovo and Iraq in an attempt to reduce contamination to the depleted uranium caused by bombings, the USA seems to have distributed these materials in various European countries.
 
The Triangle of Death
Horizons and debates interviewed the couple X * who recently sought asylum in the canton of Ticino to escape this environmental disaster (see box below). The conclusion of their asylum application that is you the reader of newspapers: For more than 20 years stores, in old cellars, waste of all kinds. In our media, nobody mentions which substances are buried, why they are here and what are their health risks. It is an established fact - and this has been published in Lancet Oncology - that these wastes have already resulted in the "triangle of death" very high rates of liver cancer, leukemias and lymphomas, and they cause great suffering.
