12.1 Sector Descriptions and Overview

This category includes the following mercury emission categories: Landfills (working face), Switches and Relays, Fluorescent Lamp Breakage, Dental Amalgam, General Laboratory Activities, Thermostats, Thermometers, Fluorescent Lamp Recycling, and Batteries. Human and animal cremation estimates include CAPs as well as mercury and are discussed in section 31 of the TSD.

These sources include a mix of EPA-generated and SLT-submitted emissions for the SCCs listed in Table 12.1. Additional descriptions of the individual types of activities are provided in the source-specific sub-sections below.
