The body of our children is polluted by contaminants
The first study of its kind found concentrations of certain chemicals higher among children than among their parents
Ottawa (Ontario) - The dangerous toxic pollutants were detected in the body of every child and every parent who participated in a Canadian study whose results were announced today by Environmental Defence. The first Canadian study of its kind found concentrations of certain chemicals higher among children than among their parents. Families volunteers from the BC, Ontario, Quebec and New Brunswick have participated in the study.
The report innovator Children, Toxic Nation: A Report on Pollution in families reveals the presence of toxic products, such as antitaches, fire retardants, mercury, lead, DDT and BDP among Canadian children and their parents . In several cases, the children in the study were more contaminated than their parents by chemicals still in use, including antitaches (perfluorinated compounds or PFCs), brominated flame retardants (PBDEs), heavy metals, insecticides metabolites organophosphate and PAHs (polycyclic aromatic hydrocarbons). Many chemicals found in the bodies of children are associated with cancer, developmental disorders, respiratory disorders, neurological damage and the endocrine deregulation.
This report is the first in Canada to verify the presence of children and their parents, a range of toxic substances into the environment and in the manufacture of products of everyday use. It demonstrates that Canadian families are contaminated, no matter where they work, play or go to school, and no matter where they live or the age of their members.

Number of industrial activities may affect the fish and its habitat, including exploitation of oil and gas, mining, chemical industries, maritime transport and electricity generation. In order to support and to wisely manage these activities to ensure they have a minimal impact on ecosystems, policy decisions and regulations fair and informed must be taken. Hence, the Directorate of Environmental Sciences DFO focus its scientific expertise on the environmental impacts that must be taken into account in decision-making.

The coastal and estuarine sediments contain many substances, some of which are toxic said: heavy metals, polyaromatic hydrocarbons, organochlorines (PCBs), pesticides and biocides divers. Their dredging and dumping at sea poses the problem of mobility elements and toxic substances and their effects on living organisms. The process involved in the detention or release of contaminants associated with sediment are regulated to a large extent by the physical and chemical properties of the environment of the site of deposit, but also linked to microbiological activity in the sediment dredged. Particular attention is given to toxic contaminants, persistent and bioaccumulative.
The data REPOM, as well as data Ifremer on the quality of coastal waters, are integrated into the "Information System on Water" established by the MEDD from 2007.

 Each year, is applied about 20 million kilograms of pesticides on crops in the Canadian Prairies. Scientists still do not understand quite the migration process pesticides depui the area of application or their impact on water quality.Since the 1940's, using synthetic pesticides chlorinated, but scientists have established for several decades that some of them causing serious environmental problems.
Although Canada has adopted regulations and established a process of environmental screening, many questions remain unanswered about the mode of penetration of pesticides and their residues in aquatic ecosystems.
We know the potential effects on the environment of less than 5% of the 23 000 substances manufactured, imported or used in Canada for commercial purposes.
The contaminants are found usually in the form of mixtures, whose toxic effects are still unknown. The interaction of mixtures such as nutrient-contaminants and metals is a problem that requires urgent environmental benefit research.
Recent studies suggest that a wide variety of potentially toxic substances entering the environment and many of them were not considered contaminants so far. These substances may have adverse effects on the environment at concentrations much lower than those previously recognized by scientists.
