"And scientists know that when you have persistent pollutants in dust, they get into children."

Mercury is a persistent pollutant - it does not break down in the environment.

Our waters have become home to persistent pollutants, the most rapidly growing type of pollution.

Methamphetamine in soils has shown to be a persistent pollutant.

Such persistent pollutants require a special purifying treatment to remove them from wastewater.

As well, there are many persistent pollutants that are affected slowly, or not at all, by this process.

The results indicate that the major part of the persistent pollutants cycling in the lakes is due to internal lake processes.

The study makes the assertion that the difference in weight gain may be the result of long-term effects of persistent pollutants.

It is a global, diffuse and persistent pollutant.

Persistent pollutants are the fastest growing type of pollution and they include substances that degrade very slowly or cannot be broken down at all.

The use of organobromine fire-retardants is growing but is also controversial because they are persistent pollutants.

Persistent pollutants – Canada.

Toxic heavy metals and small but important quantities of persistent pollutants, that have a habit of accumulating in the food chain, are also present.

This indicated that the degradation of lipid and organic carbon was higher than the release of persistent pollutants from settling particles.

The in situ elimination rates of these persistent pollutants were found to describe tissue turnover rates in lake trout.

Polychlorinated biphenyls (PCBs) are persistent pollutants identified worldwide as human blood and breast milk contaminants,' they wrote.

The elimination of this source has resulted in significant reductions of dioxins and furans, as well other bioaccumulative and persistent pollutants.

Contrary to earlier findings for lakes, we found a positive relationship between trophic status (total phosphorus) and uptake of persistent pollutants in stream biota (trout).

It has also been reported that "adverse effects on learning and behavior are strongly associated with fetal exposure to persistent pollutants, not with breast milk exposure".

The results indicate that eutrophication of streams by agricultural activities and excessive nutrient loading may increase uptake of persistent pollutants in stream biota.

Persistent pollutants that enter the lakes are retained in the system for long periods since less than 1% of the water flows out of the lakes annually.

Persistent pollutants include pesticides, such as DDT, and industrial chemicals, most famously the PCBs.

A new PCPA should commit the government to pesticide reduction and the elimination of pesticides that are persistent pollutants or hormone disruptors.

Some persistent pollutants, such as some organic pollutants and nuclear waste are absorbed very slowly or not at all; ecological economists emphasize minimizing "cumulative pollutants".
