“…PST-positive shell sh from all locations were highest from December to May match months with those reported in the Results. These ndings are comparable with seasonal variation in shell sh concentrations of PSTs (Taleb et al, 2001;Harley et al, 2020), which are mostly detected in spring, early summer, and autumn in the South China Sea (Yao et al, 2019).…”

Paralytic shell sh toxins (PSTs) produced by certain marine dino agellates accumulate in lter-feeding marine bivalves. We used LC-MS/MS to detect and quantify 13 PSTs in 188 shell sh samples of 14 species collected from Shenzhen city's Buji seafood wholesale market from March 2019 to February 2020. Twenty-six of 188 shell sh samples (13.8%) were PST-positive, with highest values in samples of the Noble clam Chlamys nobilis (10/34, 29.4%). Samples originating from Nan'ao island among 11 source sites in China recorded the highest detected rate (7/17, 41.2%). Samples containing PSTs were concentrated in Spring and Winter, with the highest levels in March > December > January. Among PSTs detected, C1 was dominant. Acute dietary exposure assessments for Shenzhen residents were based on P 99 consumption data (139.2g/day) and maximum PST concentration for each shell sh species. The outcome for Chlamys nobilis was 2.4 ~ 3.7-fold higher than recommended ARfDs (0.5 ~ 0.7 µg STX eq./kg bw/day). Mean PST concentration (10.9 ~ 134.1 µg STX Eq. /kg), mean shell sh consumption (4.8 g/day) and P 99 consumption data were used to assess chronic dietary exposure. The results were lower than the recommended ARfDs. In conclusion, residents in Shenzhen are at risk for acute PST poisoning, while relatively safe from chronic PST exposure.

“…( Lesson 5, Cultivate Mutual Respect ). A reverence for nature informs our current collaborative studies on the resilience of coastal communities to climate change, using integrative social-ecological systems approaches (e.g., [ 42 ]) to address issues such as expansion of intensity and geographical scope of HABs [ 43 ], in Washington State through the SoundToxins partnership [ 44 ] and in other parts of the world, such as Alaska [ 45 , 46 ], Guatemala [ 47 ] and India [ 48 ]. In the end, we realize that mutual respect of humans for nature and for one another go hand in hand.…”

The most proactive approach to resolving current health and climate crises will require a long view, focused on establishing and fostering partnerships to identify and eliminate root causes of the disconnect between humans and nature. We describe the lessons learned through a unique scientific partnership that addresses a specific crisis, harmful algal blooms (HABs), along the northeast Pacific Ocean coast, that blends current-day technology with observational knowledge of Indigenous communities. This integrative scientific strategy resulted in creative solutions for forecasting and managing HAB risk in the Pacific Northwest as a part of the US Ocean and Human Health (OHH) program. Specific OHH projects focused on: (1) understanding genetic responses of tribal members to toxins in the marine environment, (2) knowledge sharing by elders during youth camps; (3) establishing an early warning program to alert resource managers of HABs are explicit examples of proactive strategies used to address environmental problems. The research and monitoring projects with tribal communities taught the collaborating non-Indigenous scientists the value of reciprocity, highlighting both the benefits from and protection of oceans that promote our well-being. Effective global oceans and human health initiatives require a collective action that gives equal respect to all voices to promote forward thinking solutions for ocean health.

“…As a matter of fact, while automated instruments play significant roles in some regional programs on the West Coast of the United States [146] and France [147], good results have been obtained with satellite remote sensing in China [148], Korea [149], Iberian Peninsula [150], Scotland [151], Ecuador [152], and Chile [153]. Citizen science programs are also increasingly becoming critical to improving the spatial and temporal coverage of regional HAB monitoring programs, as observed in some areas in the United States (e.g., Alaska and Gulf of Mexico [154,155]) and France [157].…”

This chapter provides the first overview of the disruptive impacts of HABs on the blue economy, with a particular focus on the application of science and technology in their management and mitigation. We present case studies of HABs in five different locations as examples of their effects on different sectors of the blue economy. We also review the main technological advances in recent decades, and current needs for improved understanding of HAB dynamics, monitoring, and forecasting. An evident gap in dealing with HABs in the frame of the blue economy is the inequity in resources available for monitoring worldwide. While developed countries count on advanced (and even impressive) tools for monitoring and early warning (e.g., automated tools, oceanographic moored instruments, forecast models), efficient monitoring in most developing countries is still missing and, when performed, mainly focused on seafood products intended for export. Basic research on HABs in these countries is also frequently deficient, with modeling capabilities for early warning virtually non-existent. Considering that many (truly) sustainable blue economy activities are developed precisely in vulnerable areas with low economic power, the need Please note that this is an author-produced PDF of an article accepted for publication following peer review.
