Efetuou-se revisão de trabalhos de pesquisa sobre dispositivos de membranas semipermeáveis (DMSP), contendo trioleína para monitoramento de ambientes aquáticos. Os DMSP têm sido utilizados como amostradores passivos de pesticidas e outros poluentes orgânicos lipofílicos em água. Esses dispositivos têm-se mostrado eficientes na amostragem de água para análise de substâncias em níveis de traços e ultra-traços, tais como pesticidas organoclorados, organofosforados, piretróides, bifenilas policloradas, hidrocarbonetos aromáticos policíclicos, dioxinas, furanos e outras substâncias orgânicas apolares. Atenção especial é dada aos modelos para cálculo da taxa de amostragem e concentração dos analitos nos corpos d’água. A tecnologia de DMSP continua a ser pesquisa por cientistas ambientais que buscam a otimização das condições para exposição e análise. MONITORING OF PESTICIDE AND OTHER ORGANIC POLLUTANTS IN WATER SOURCES BY UTILIZING SEMIPERMEABLE MEMBRANE DEVICES Abstract A review of research works about semipermeable membrane devices (SPMD), containing triolein for aquatc environment monitoring was accomplished. The SPMD have been utilized as passive pesticide samplers and other lypophylic pollutants in water. Those devices have been efficient in sampling water for substance analysis in trace and ultra-trace levels, for organochlorine, organophosphorus pesticides, polychlorinated biphenyl, polycyclic aromatic hidrocarbons, dioxins, furans and other non polar organic substances. Special attention is given to models for sampling index calculation and concentration in water corps. The SPMD technology continues to be researched by environmental scientists that search the optimization of exposure conditions and analysis.

On 16 October 1996, a malfunction at the Swan Hills Special Waste Treatment Center (SHSWTC) in Alberta, Canada, released an undetermined quantity of persistent organic pollutants (POPs) into the atmosphere, including polychlorinated biphenyls, dioxins, and furans. The circumstances of exposure are detailed in Part 1, Background and Policy Issues. An ecologically based, staged health risk assessment was conducted in two parts with two levels of government as sponsors. The first, called the Swan Hills Study, is described in Part 2. A subsequent evaluation, described here in Part 3, was undertaken by Health Canada and focused exclusively on Aboriginal residents in three communities living near the lake, downwind, and downstream of the SHSWTC of the area. It was designed to isolate effects on members living a more traditional Aboriginal lifestyle. Aboriginal communities place great cultural emphasis on access to traditional lands and derive both cultural and health benefits from “country foods” such as venison (deer meat) and local fish. The suspicion of contamination of traditional lands and the food supply made risk management exceptionally difficult in this situation. The conclusion of both the Swan Hills and Lesser Slave Lake studies was that although POPs had entered the ecosystem, no effect could be demonstrated on human exposure or health outcome attributable to the incident. However, the value of this case study is in the detail of the process, not the ultimate dimensions of risk. The findings of the Lesser Slave Lake Study have not been published previously and are incomplete.
