contaminant concentration

What is the relationship between contaminant concentration and individual exposure?

Finally, the user is asked to provide contaminant concentrations for each waste.

Assessment of contaminant concentrations using the latest national and international guidelines.

The test disclosed contaminant concentrations of 2.5 parts per billion in the water drawn from the well.

The user is next asked to provide information on contaminant concentrations in the wastewater.

More accurate estimates would require local contaminant concentrations and flow data.

Since the early 1980s contaminant concentrations in biota have not changed consistently.

If contaminant concentrations at the site do not exceed the established guidelines, no further action may be required.

It can take decades (or more) for contaminant concentration in receiving media to reach steady state.

Both dramatically affect the resulting measured values of contaminant concentrations.

A more acurate estimate requires site specific contaminant concentration data.

Further fact sheets will include health effects in fish and information on current contaminant concentrations in the environment.

• Effective for a wide range of contaminant concentrations.

It is proposed to use these differences in response to extend the range over which contaminant concentrations can be monitored.

This relationship was consistent even though there was over a 10-fold range in contaminant concentrations within a given species.

Contaminant concentrations at most locations were below levels thought to induce biological responses.

Contaminant concentrations decrease with increasing wind speed as a result of dilution.

If contaminant concentration is below the guideline value, then the site is considered safe.

Human response to odor was found to be logarithmic to contaminant concentrations, and related to temperature.

But, egg and larval survival was not significantly lower in eggs with higher contaminant concentrations.

Incinerators can also handle fluctuations in flow rate and contaminant concentration relatively well.

Contaminant concentrations are multiplied by the flow rate to obtain a release value per unit time.

Emission rates are determined by using the contaminant concentration and the volumetric source flow rate.

The destruction efficiency increased with rising initial contaminant concentration.

However, there is considerable uncertainty about the factors responsible for the difference in contaminant concentrations in fish.
