Developmental assignments

Developmental Assignment Argumentation. Find an identification number system that, as far as you know, does not contain a check digit scheme. Make a case for the creation of a new identification number system that incorporates a check digit scheme. That is, give reasons why such a system/scheme might be useful and for whom. 

Developmental Assignment Combine the summary of sections 1 and 2 of this chapter with the summary written for section 3. The concepts and terms introduced in sections 1 and 2 are needed in section 3. All of these concepts will be central to the study of cryptography and check digit schemes. 

As mentioned previously (Subheading 3.3), if the substance is known to cause developmental toxicity in humans, it would not have been necessary to conduct a teratology study as part of REACH assessment. Category 1 is assigned from epidemiological data. 

H361d Suspected ofdamapiinpi the unborn child is assigned. The letter D and d, respectively, stands for development. The capital letter indicates that the corresponding substance is known to cause developmental toxic effects in humans or animals whereas the lower case letter indicates that the corresponding substance is only suspected of causing such effects. 

This section presents information on human health effects, including those known to be associated and those possibly associated with exposure to CDDs (primarily 2,3,7,8-TCDD). Since limited data exist to assign a specific route of exposure (inhalation, oral, dermal) to human studies, the information in this section is organized by health effects—death, systemic, immunological, neurological, developmental, reproductive, genotoxic, and carcinogenic effects. These data are discussed in terms of three exposure periods—acute (14 days or less), intermediate (15-364 days), and chronic (365 days or more). 

The United States Navy has been concerned for some time with protecting its military and civilian personnel from reproductive and developmental hazards in the workplace. As part of its efforts to reduce or eliminate exposure of Naval personnel and their families to reproductive and developmental toxicants, the Navy requested that the National Research Council (NRC) recommend an approach that can be used to evaluate chemicals and physical agents for their potential to cause reproductive and developmental toxicity. The NRC assigned this project to the Committee on Toxicology, which convened the Subcommittee on Reproductive and Developmental Toxicology, to prepare this report. In this report, the subcommittee recommends an approach for evaluating agents for potential reproductive and developmental toxicity and demonstrates how that approach can be used by the Navy. 

Exposure by multiple routes is assumed to be additive. The default assumption is that simultaneous exposure to multiple agents having the same site or mode of action results in additive effects. Thus, for example, estimates of the developmental toxicity of chlorinated dibenzodioxins and dibenzofurans should consider the use of toxic equivalency factors (Safe 1993), provided the quantitative value assigned to each congener is relevant to the toxic effect under consideration.

Some reproductive toxic effects cannot be clearly assigned to either impairment of sexual function and fertility or to developmental toxicity. Nonetheless, chemicals with these effects would be classified as reproductive toxicants with a general hazard statement. 

Some have criticized those groups charged with protection of the public health for failure to designate a code or notation which can be assigned to a chemical showing it to be a reproductive or developmental...
