“…This agrees with results on mercury transport in the contaminated Gulf of Trieste where model considerations and actual measurements showed that most mercury is transported adsorbed on suspended particles and that transport of dissolved total mercury is almost negligible (Rajar et al, 2004). Similarly, mercury discharged to the Bay of Kuwait during 1963 to 1985 appears to be spreading towards the northern part of the Bay (Al-Zamel et al, 2010). Mercury concentrations in the top 2 cm of the sediments outside a former chlor-alkali plant in Chaleur Bay, New Brunswick, Canada have decreased considerably after the plant closed in 2008 (Walker, 2016) and the author ascribes this decrease to burial by recent sediment deposition.…”

“…Also, in the contaminated Gulf of Trieste model considerations and actual measurements showed that most mercury is transported adsorbed on suspended particles and that transport of dissolved total mercury is almost negligible (Rajar et al 2004 ). Spread of mercury has also been observed in the Bay of Kuwait where mercury discharged to the bay during 1960s to the 1980s appears to be spreading towards the northern part of the Bay (Al-Zamel et al 2010 ).…”

Concentrations of mercury in sediment and benthic invertebrate fauna of Nissum Broad, North-western Jutland, Denmark were investigated. The western coast of Nissum Broad is Harboøre Tange, along which heavy mercury contamination - caused by discharge from production of mercury containing seed dressers in the 1950 and 1960s – was documented in the 1980s. Recent investigations showed marked decreases in mercury contamination in the near shore sediments along Harboøre Tange since the 1980s and the present investigation was initiated to learn if the loss of mercury from Harboøre Tange had led to an increased mercury contamination in the neighbouring marine area, Nissum Broad. Mercury concentrations in the surface sediment correlated with the content of organic matter and the slope of the regression is a good indicator for the degree of mercury contamination. Average mercury concentrations in the upper 5 cm of the sediments ranged between 0.9 and 71 ng g− 1 dry weight (dw) with only 1 station exceeding the Background Assessment Concentration of 70 ng g− 1 dw. Average mercury concentrations in blue mussels Mytilus edulis (169–260 ng g− 1 dw) and periwinkles Littorina littorea (66–203 ng g− 1 dw) exceeded those in uncontaminated areas and the Environmental Quality Standard of approximately 100 ng g− 1 dw. Present sediment mercury concentrations in Nissum Broad are approximately half of what they were in the 1980s, rendering it unlikely that mercury lost from Harboøre Tange has been deposited there. Sediment and organism concentrations did not show any correlation.
