The United Nations recognised the transfer of invasive species across natural barriers as one of the greatest pressures to the world's oceans and seas. The BWM Convention sets the global standards on ballast water management (BWM) requirements, while recognising that regional and local specifics have to be considered for its effective implementation. In the Adriatic Sea cross-border activities were conducted to provide for essential information/data and tools to support a regionally coordinated implementation of the BWM Convention...

In the early 1990s, a cliff-face disposal-system discharging approximately 940 ML/day, or 80% of sewage generated by the City of Sydney (Australia) (population 3.3 million) was replaced by three deepwater ocean outfalls. An 18-year benthic infauna monitoring study was undertaken to address earlier concerns of long-term accumulation from sewage discharges and potential adverse effects on the marine environment. Assessment of outfall community structure indicated organic input from discharges has not resulted in sediment anoxia...

A cliff-face disposal system discharging approximately 940 ML/day, or 80% of sewage generated by the City of Sydney (Australia) (population 3.3 million) was replaced by three deepwater ocean outfalls in the early 1990s. Enrichment of anthropogenic chemicals from cliff-face discharges raised concerns regarding long-term accumulation of sewage particulates and associated contaminants in offshore sediments and for reduced beach water quality. The current post-commissioning investigation detected a southward gradient of sediment fining and increased total organic carbon in the study region...

Oceanographic processes are examined and used to assess their effect on the movement and dilution of wastewater discharged from Sydney's three deepwater ocean outfalls. Such processes link wastewater discharges with observed changes in biological communities and the accumulation of contaminants in the sediments. The East Australian Current, coastal trapped waves and local winds contribute 40%, 20% and 10% respectively to the total spectral energy in the along-shore currents off Sydney. Median dilutions at the edge of the initial dilution zone range between 185:1 and 347:1...

Shoreline discharge representing approximately 80% of sewage generated by Sydney (Australia) was replaced with three deepwater ocean outfalls between 1990 and 1991. Beachwatch bacterial monitoring data collected between 1989 and 2016 were analysed to assess the impact of commissioning on bathing water quality along 32 km of coastline. Bacterial contamination was reduced by 26-99% during the first 32 months post-commissioning and in the longer post-commissioning period, 1993 to 2016, bathing water quality improved for 31 beaches...

The mechanism of fish kill events is not thoroughly understood in Kuwait Bay (KB). However, it is obvious that fish kill events have a close relationship with hypoxia due to some biogeochemical processes. Hydrodynamics controls the dissolved oxygen (DO) concentration that occurs within various spatial and temporal scales. The current study utilizes a previously validated hydrodynamic model to drive a three-dimensional water quality model for KB. The water quality model was validated using comprehensive field measurements during the summer of 2018...

To exploit the resolving ability of rare earth element and yttrium (REY) in resuspension binary mixing model, and discover potential new REY-related resuspension proxy, this preliminary research studied the geochemical signature of REY in different Jiaozhou Bay samples including surficial/core sediments and settling trap-collected particles. Close quantitative relation for bulk concentration in particles, sediments and fine-grained fraction of major river sediments around the Yellow Sea, approved the priority contribution of catchment detrital materials...

Polycyclic aromatic hydrocarbons (PAHs) are toxic and ubiquitous in the environment and pose great risks. Bioaccumulation by plankton is the outset for PAHs entering marine food web. The long-term driving environmental factors for bioaccumulation of PAHs in zooplankton have not been well investigated. In this study, high variation of PAH concentrations in zooplankton (5 to 5440 ng g-1 dry weight) was found, with the highest PAH levels near the transect Kaohsiung Harbor. Precipitation significantly enhances the PAH concentration in zooplankton and affects the PAH distribution in the water column, indicating PAH input from terrestrial runoff...

In this study we examined the adsorption characteristics of heavy metals on microplastic through laboratory test and field test. We demonstrated that polyvinyl chloride, polypropylene, polyethylene, polyamides and polyformaldehyde could adsorb lead, copper and cadmium in the simulating solution, and the heavy metals showed higher adsorbance on PVC and PP particles compared with PA, PE and POM. In the field experiment, the adsorption rate and concentration of heavy metals varied significantly among different plastic types and locations...

Marine litter is a global, persistent, and increasing threat to the oceans, and numerous initiatives aim to address this challenge. Fishing For Litter (FFL) is a voluntary clean-up scheme, where litter is collected as part of routine fishing operations. We surveyed fishers (n = 97) and stakeholders (n = 22) in the UK to investigate perceptions of FFL, its strengths and weaknesses, and potential co-benefits of the scheme. Fishers reported being aware of and concerned about the negative impacts of litter...

Non-point sources of sewage-related pollution in tropical marine waters are difficult to ascertain. Enterococci (ENT) are widely used as indicators of human waste but their efficacy in tropical waters is highly debated due to natural presence in tropical soils. Clostridium perfringens (CP) is often used as a secondary indicator of fecal contamination because its presence indicates sewage, and in tropical waters environmental sources are unlikely. We analyzed a 27-year dataset containing over 29,000 samples collected by the State of Hawaii, to determine a proposed CP standard for detecting human sewage, which has applicability throughout tropical marine waters globally...

REVIEW
Ileana Federigi, Marco Verani, Gabriele Donzelli, Lorenzo Cioni, Annalaura Carducci
This review examines the aims of and approaches to the Quantitative Microbial Risk Assessment (QMRA) of untreated recreational waters. The literature search was conducted on four databases and yielded 54 papers, which were analyzed on a quantitative (time-trend, geographical distribution, water type) and qualitative (aims, source of microbial data, pathogens and their measurement or estimation, ways to address variability and uncertainty, sensitivity analysis) basis. In addition, the parameters, implications, and limitations were discussed for each QMRA step...

The Mediterranean Sea is one of the most polluted seas in terms of marine debris. To analyze the ingestion of anthropogenic particles in two areas, 197 gastrointestinal tracts from four fish species - Trachurus mediterraneus, Sardina pilchardus, Engraulis encrasicolus and Boops boops - were studied. 127 anthropogenic particles were identified in the gastrointestinal tract of 28% of the samples using visual sorting methods. Individuals from the peninsular coast showed higher ingestion occurrence (36%) than those from the Balearic Islands (12%)...

In this study, a general methodology that is based on numerical models and statistical analysis is developed to assist in the definition of marine litter cleanup and mitigation strategies at an estuarine scale. The methodology includes four main steps: k-means clustering to identify representative metocean scenarios; dynamic downscaling to obtain high-resolution drivers with which to force a transport model; numerical transport modelling to generate a database of potential litter trajectories; and a statistical analysis of this database to obtain probabilities of litter accumulation...

G F Birch, Y Shalem, K Lewtas, C H Besley
The influence of sedimentary metals on the cockle A. trapezia tissue was examined using a strong difference in sedimentary metal concentrations in an embayment (Hen and Chicken Bay) highly contaminated in Cu and an adjacent cove (Iron Cove), strongly enriched in Cd, Cu, Pb and Zn within the heavily-urbanised Sydney estuary catchment (Australia). Statistically significant differences were recorded for cockle tissue metal concentrations between the study locations reflecting differences in surficial sediment metal concentrations...

The levels, vertical distribution and sources of hydrocarbons and petroleum biomarkers were estimated for the first time in sediment cores (0-40 cm) from ten coral Islands of the Persian Gulf, Iran. Discrepant hydrocarbons, including linear n-alkanes (n-C11 to n-C40 ) and isoprenoids (AHs), aliphatic ketones (AKs), hopanes and steranes were measured in all core samples, showing mean concentrations ranging from 209 to 5388 μg g-1 dw (∑30 AH), 2-244 μg g-1 -dw (∑13 AK), 189-3713 ng g-1 dw (∑31 hopane) and 42-3864 ng g-1 dw (∑15 sterane), respectively...
