Abstract:

A geographical survey of sediments in the Derwent Estuary, near Hobart (Tasmania), for sterol biomarkers of faecal pollution has established the extent, distribution and severity of sewage pollution in the estuary. Analysis of biomarkers for terrestrial plants has also determined the distribution of pulp fibre discharged from a paper mill at Boyer in the upper estuary. Contributions from other sources of extractable organics, such as hydrocarbons and terrestrial plant and animal faecal matter from stormwater and creeks were qualitatively evaluated. On the basis of the distribution of the faeca

Abstract:

Following surveys recently carried out in Maputo estuary, a survey with the purpose of acquiring data required to characterize the estuary was carried out in December 1983. After reviewing the hydrology of the tributaries to the estuary, the parameters to be monitored - salinity, conductivity, temperature, and dissolved oxygen, are referred. Finally, taking also into account previous information available, an evaluation of the results, and an assessment of the estuary are done. The estuary can be classified as well mixed, since the vertical salinity gradients found are small. The Umbeluzi estu

Abstract:

Environmental Context.Dating estuary sediments provides insights into the materials entering the estuary and can pinpoint when the contamination occurred. Heavy metal contamination is a known health risk but attributing it to a source can be contentious. For a sample sourced downstream of a city and a mining region, lead-210 dating and stable lead isotope analyses uncovered the sources of lead inputs. These methods quantified the extent that upstream mining activities and, for the first time, the extent that non-mining inputs (vehicles, industry) contributed to the estuary’s pollution. Abstrac

Abstract:

SynopsisDuring the period of severe sewage pollution of the Clyde Estuary and severe industrial pollution of the Garnock Estuary, these two estuaries could be distinguished by unusual abundances of one particular alga in each estuary, respectively Melosira nummuloides and Rosenvingiella polyrhiza. However, in terms of species presence data alone these estuaries did not differ from others in the British Isles. The unusual abundances of these two algal species might be ascribed to their special characteristics, related to the polluted conditions in the estuaries.

Abstract:

The Nakdong river estuary in South Korea has two important functions: first, remediating water pollution from the Nakdong river; second, mitigating the risk of disaster caused by waves from the open sea. The two functions of the Nakdong river estuary have been continuously threatened due to constant development pressure. This short note tries to investigate the non-market value of the water pollution remediation and disaster risk mitigation functions. For this purpose, 1000 households throughout the country were randomly selected, and a choice experiment (CE) survey of them was implemented in

Decline of the Beluga whale population in the upper estuary of the St. Lawrence River may be related to the high content of toxic metals and organic chemicals in their tissues. For three years, the National Water Research Institute has conducted research cruises of the St. Lawrence River to identify the major toxic chemical pollutants in the river and to determine their transport to, and fate in, the upper estuary. The impact of toxic chemicals in the estuarine zone is tied not only to their fate in the increasing salinity and turbidity zone of the upper estuary but to their source, transport

The Chesapeake Bay is the largest estuary in the United States, and was once one of its most productive. Historically, the Chesapeake supported thousands of migrant and resident species, including oysters, blue crab, shad, herring, and waterfowl. Today the estuary's productivity is a shadow of what it once was. In 1880, for example, the oyster harvest was 120 million pounds, but this declined to a mere 3 million pounds by 2000—and that actually represented an increase from a historic low in 1993. While the native Chesapeake oyster has fallen victim to disease, a major contributing factor to it

Abstract:

This study conducted an analysis of microplastics (MPs) pollution in a coastal region of the Pearl River Estuary (PRE) in the South China Sea. The results show that the abundance of MPs during the rainy season reached 545.5 particles m−3, which was 1.85-fold higher than during the dry season. The spatial distribution of MPs also varied offshore in the following order: the river > estuary > sea. The average abundance of MPs in the river was 1.17-fold higher than that of the estuary and 4.65-fold higher than that of the marine environment. There were large amounts of gray, white, and green

Abstract:

The spatial distribution, enrichment, and accumulation of zinc (Zn) in the surface sediments of Jen-Gen River estuary, Taiwan, were studied. Results show that samples collected from 11 stations near the estuary of Jen-Gen River contain 221–627 mg/kg of Zn with average of 502±114 mg/kg. The spatial distribution of Zn reveals is relatively high in the river mouth region, and gradually diminishes toward the harbor region. This indicates that upstream industrial and municipal wastewater discharges along the river bank are major sources of pollution. Enrichment factor analysis indicates that the se
