The present study highlights that, temperature, salinity and nitrate are key factors, collectively explaining 76 % of variance of <em>Phaeocystis</em> bloom in Digha coastal waters. Among these, temperature is crucial and accounts for 69 % of variance in bloom formation. During December, cool-dry northeasterly winds considerably reduced the temperature (<24 °C), while the freshwater input modified the coastal environment to polyhaline, nitrate and silicate rich (>5 μM); these likely triggered the <em>Phaeocystis</em> bloom formation.

Additionally, management strategies such as depuration and cooking were evaluated for their effectiveness in reducing human health risks associated with exposure to these identified EDCs. Comprehensive screening identified 85 potential EDCs, including polycyclic aromatic hydrocarbons (PAH — 64.0 %) and organochlorine pesticides (OCPs — 13.1 %).

The depuration process significantly reduced the level of all pollutants to below the limit of quantification (LOQ), while cooking could only slightly reduce the mean concentration of PAHs from 23.67 ng/g to 17.33 ng/g. The human health risk assessment for the pre- and post-cooked clam samples revealed higher hazard index values (>1), indicating immediate risk of dietary exposure.

This study used the benzene polycarboxylic acid (BPCA) method to quantify BC concentrations in the surface waters and sediments of semi-enclosed and open estuaries in the North Beibu Gulf, South China Sea, across different seasons. Results showed that hydrological factors, such as urban riverine input, particle settling, and sediment resuspension, significantly influence BC dynamics. Dissolved BC (DBC) concentrations were highest in summer (125.5 ± 67.3 μg/L), driven by riverine input, while particulate BC (PBC) concentrations decreased rapidly along the river-estuary-coastal gradient (4.1–187.7 μg/L) due to particle settling. In winter, reduced riverine input increased the role of sediment resuspension, elevating PBC concentrations in the open estuary compared to the semi-enclosed estuary. Seasonal variations in BPCA composition showed differences in BC aromatic condensation, influenced by photodegradation, adsorption, and resuspension. Sedimentary BC (SBC) levels were stable (0.087 ± 0.048%dw), accounting for 14.0 ± 4.21 % of sedimentary organic carbon (SOC), which is a higher proportion compared to the contributions of DBC to dissolved organic carbon (DOC) (5.58 ± 2.74 %) and PBC to particulate organic carbon (POC) (6.81 ± 2.94 %).

By analyzing four decades of green turtle (<em>Chelonia mydas</em>) strandings from the Main Hawaiian Islands, we elucidate temporal and spatial trends. In Hawai'i, fibropapillomatosis (FP) has been the dominant threat for stranded turtles since records began in 1982. In the last decade (2010–2019), FP constituted on average 25 % of stressors in stranded turtles, followed by fishing lines (22 %), hooks (8 %), shark predation (5 %), boat strikes (5 %), and net entanglements (3 %). As of 2016, fishing line injuries constitute the most common primary threat. Turtles injured by lines and hooks were often found and released alive (hooks: 86 % alive, lines: 64 % alive), underscoring the importance of timely reporting and response. O'ahu was found to be the main hotspot for hook-and-line strandings, while there was more variation across islands for the other stressors. Spatial predictions highlighted areas without prior stranding observations, suggesting that some strandings may go undetected. As the main hotspot for fishing line strandings, we modelled the presence of derelict line around O'ahu using data from in-water debris cleanup efforts; we found that (1) derelict fishing line was positively associated with shore access points and boat harbors and (2) negatively associated with human population density. The increase in strandings with fishing line could be a result of the recovering turtle population and their overlap with year-round coastal fishing activities.
