Abstract
This body of work proposes a study of potential community impacts from the shipping industry. In particular, the contribution of hazardous air pollutants (HAPs) and other toxics from large ocean-going vessels (OGVs). In this study, samples were taken from tier II and tier III technology class vessels with category 3 engines. The study serves to quantify the chemical composition and concentration of air toxics from these two technology classes as well as the two regulatory fuel blends used in transport. The two fuels contain different sulfur content values. A full spectrum of samples was collected at different loading points based off the ISO 8178 testing cycle and the two fuel types used. Samples were collected from two main engines, the auxiliary engines as well as a boiler for each vessel. The work shown will give a full chemical analysis of the HAPs and other toxics emitted by both technology classes, including a range along the California coast from the port of Oakland to the port of Long Beach to show the potential risk and health impact to local portside communities. A full spectrum of species from the engine stack emissions will be shown from aldehydes and ketones, polycyclic aromatic hydrocarbons, some inorganics, and more.
