Shipping emission inventories in China's Bohai Bay, Yangtze River Delta, and Pearl River Delta in 2018

Trends and Challenges Regarding the Source-Specific Health Risk of PM2.5-Bound Metals in a Chinese Megacity from 2014 to 2020

“…This promotion is related to Shenzhen’s strengthening of shipping emission control and the prohibition of high sulfur fuel in ports. Since 2014, shipping fuel emissions have begun to be a focus, including the use of low-sulfur oil products, “oil-to-gas”, “oil-to-electricity”, and the promotion of gas and electric nonroad mobile machinery . Shenzhen improved the fuel quality by implementing low-sulfur fuel (<0.5% sulfur content) for ocean vessels and diesel oil within 10 ppm sulfur content for inland ships, which was promoted using <0.1% low-sulfur fuel for partial ships in 2019.…”

The ship's low-sulfur oil subsidy policy was adjusted to increase the utilization rate of shore power in 2019.…”

Impacts of the COVID-19 epidemic on merchant ship activity and pollution emissions in Shanghai port waters

“…For example, the Spring Festival could lead to a decrease in pollution from ships. Wan et al (2020) pointed out that among China's three major port groups, the Yangtze River Delta region has the largest emissions, accounting for 47.85% of the total ship emissions in 2018. Shi et al (2020) found that emissions significantly vary with different merchant ship types.…”

Potential Source Regions and Transportation Pathways of Reactive Gases at a Regional Background Site in Northwestern China

“…However, growth contribution to different regions also differs, and reactive gas levels and potential sources vary greatly among geographical locations in Asia, as shown in Table 1. For China, specifically, many scholars have studied reactive gases in areas with highly polluting emissions, such as cities [11,12], road traffic [13,14], and ports [15,16]. ere are relatively few reports on the background concentration of reactive gases compared to highly polluting areas such as cities, and field research on atmospheric constituents of regional background sites can not only provide valuable information on the impact of human activities, but also help illuminate the scope of regional air pollution.…”
