Bioavailability from Environmental Media. No information on the presence of 3,3 -dichloro-benzidine in foods was located in the available literature. The Canadian Government s Priority Substances List Assessment Report for 3,3 -dichlorobenzidine (Government of Canada 1993) also reports that no data on the levels of 3,3 -dichlorobenzidine in drinking water or foodstuffs were identified within either Canada or the United States. Because 3,3 -dichlorobenzidine has been found to bind strongly to soil constituents (Berry and Boyd 1985 Chung and Boyd 1987), Law (1995) concluded that it would also bind strongly to sedimentary material in the marine aquatic environment and thus may have limited bioavailability.

The state institutions can also offer orientation (in so far as this is done on the basis of a far-reaching discourse within society). This includes the development of a national chemicals strategy, for example, or the publication and specialised validation of priority substance lists that require special attention when designing products and processes.

For all those chemical substances so categorized as needing further attention, a screening risk assessment is required. There can be three results at this stage no further action is required, the chemical substance is determined to be toxic and measures may be needed for control, or it is placed on the Priority Substances List (PSL) and subjected to an in-depth assessment.

The aim of this work is to demonstrate how the screen printed electrodes (SPEs) can be used for on site heavy metals monitoring in surface waters in the frame of the WFD. The sensors used consist of mercury-coated screen-printed electrodes coupled with square wave anodic stripping voltammetry (SWASV) (Palchetti et al., 1999). Three metals Cu, Cd, and Pb which are classically analysed in water matrices have been considered. Moreover, Cd and Pb belong to the priority substances list of the WFD. Performance criteria of the device are first established to evaluate the level of confidence of the method. The potential use of the device and its main advantages are then highlighted through two illustrative field applications.

It is beyond the scope of this publication to delve completely into the nuances of detailed quantitative risk assessments, but a few typical considerations can be presented. As an example, we will consider the risk assessment for ethylene glycol recently carried out by Health Canada (HC) in its second Priority Substance Listing (PSL2) assessment for the chemical, as required under the Canadian Environmental Protection Act (CEPA) of 1999. Ethylene glycol represents an interesting example because humans and the environment can potentially be exposed due to its common use as the active component of anti-freeze and as a component of house paints.

The mandate to keep the environment free of toxic chemicals falls under the Canadian Environmental Protection Act (CEPA), which is administered by both Environment Canada and Health Canada. Even though MTBE has been assessed as nontoxic under the CEPA Priority Substances List, its effects on humans are still controversial (Environment Canada and Health Canada, 1992). Even though many investigators have found that MTBE does not pose a substantial health risk to humans, the effects of MTBE and other oxygenates are still relatively unknown (Duffy et al., 1992 Silvak and Murphy, 1991 ATSDR, 1996). No real studies have been done on the effects of this substance on human health.

Pentachlorophenol is very toxic and more persistent in the soil than most organic compounds and the spill number, spill volume, and supply volume are much less. It is ranked tenth, just below potassium chloride, on Environment Canada s priority substance list of hazardous chemicals (Fingas et al., 1991). This is shown in Table 38.1.

The screening of chonicals on the DSL is administered jointly by the Ministries of Health and the Environment. Chemicals that meet one or more of the screening criteria are considered candidates for classification as toxic as defined by CERA and are placed in a pool for further study. When screening of all of the substances on the DSL was completed several years ago, approximately 4,000 substances were found to meet one or more of the criteria for toxicity as defined by CERA. Substances believed to pose the greatest risks are moved to a Priority Substances List for in-depth risk assessment. If determined to be toxic within the meaning of the Canadian Environmental Protection Act, a chemical is placed on Canada s Toxic Substances List, also referred to as Schedule 1. To date, some 200 chemicals have been classified as CEPA toxic and placed on Schedule 1.
