CTSA - Chapter 2: Data Collection
This chapter contains information used to evaluate the health, environmental and regulatory concerns associated with the individual chemicals found in the lithographic blanket washes, and discusses how this information was obtained. Section 2.1 addresses the organization of the 56 specific chemicals that compose the blanket washes into generic chemical categories. Section 2.2 includes information on the physical and chemical properties of each specific chemical. Melting point, vapor pressure and the bioconcentration factor are among the many properties detailed in this section. Section 2.3 presents known human health toxicological data for each chemical. Information on the exposure routes, toxicity endpoints (such as carcinogenicity, developmental toxicity and neurologic effects), and exposure levels of concern for the chemicals are included in this section. Section 2.4 contains environmental effects data for each of the 56 chemicals. Included here is information on the chemical's acute and chronic aquatic toxicity levels for fish, invertebrates and algae, and an environmental hazard ranking for each chemical. Section 2.5 identifies which of the specific chemicals are subject to federal environmental regulations and describes each of the regulations that apply. The focus in Section 2.6 shifts from specific chemicals to the actual blanket wash formulations submitted by suppliers. In this section, safety hazard classifications for reactivity, flammability, ignitability and corrosivity have been assigned to each of the blanket washes.
