The following policy document is intended to provide guidance and information to the Pest Management Regulatory Agency (PMRA) personnel and decision-makers and to the public. This document describes the processes used by PMRA scientists, in dietary risk assessments (DRA), to quantify the level of food residue exposures to consumers of all ages.

Aggregate exposure and risk assessments involve the analysis of exposure to a single chemical by multiple pathways and routes of exposure. The pathways of exposure considered in this general principles document include the potential for pesticide residues in food and drinking water, as well as residues from pesticide use in residential, non-occupational environments.

The following policy document is intended to provide guidance and information to PMRA personnel and decision-makers, and to the public. As a guidance document, the policy in this document describes the process used by PMRA scientists in dietary risk assessments.

This document describes the approach that the Canadian Pest Management Regulatory Agency (PMRA) will use for identifying pesticides that cause common toxic effects by common mechanisms of toxicity.

The following document is a policy/guidance document that reflects the United States Environmental Protection Agency's (U.S. EPA's) recent dietary risk assessment science policy/guidance paper entitled, Choosing a Percentile of Acute Dietary Exposure as a Threshold of Regulatory Concern (March 16, 2000).

This data set provides pesticide sample analyses results for stream water samples for the province’s Pesticide Monitoring Program. The sampling includes a total of 9 rivers across PEI, with at least 3 of the rivers being sampled each year. Stream water samples are collected at least once per year during wet weather sampling conditions. Department staff collects the samples, which are then sent to a laboratory for analysis.

weight, body surface area, inhalation rates, ingestion of dust and soil, and drinking water consumption to ensure consistency of approach. Values that are used are representative of the Canadian general population. Exposure is estimated separately for different age groups because of physiological and psychological differences that may affect exposure.

This data set provides pesticide sample analyses results for drinking water samples for the province’s Pesticide Monitoring Program. Over 100 wells are monitored annually, with samples being collected in drinking water wells of private homes, schools, municipalities, and seniors’ housing facilities. Sampling of the wells is conducted each January/February by Departmental staff. The samples are sent to a laboratory in New Brunswick for analysis.

The Public Registry is a collection of non-confidential information on pesticides and the pesticide regulatory system. All publicly available information on currently registered pesticides is available here.

Pesticides are stringently regulated in Canada to ensure they pose minimal risk to human health and the environment. Health Canada relies on a number of mechanisms to protect your health and the environment, throughout a pesticide's lifecycle.
