Total phosphorus (TP) exports from the rivers draining into Lough Neagh increased between 1974 and 2000 despite lower TP inputs to the rivers from point sources. Over this period annual diffuse exports of dissolved reactive P (DRP) increased by 238%,

An upward trend in soluble reactive phosphorus (SRP) concentrations in Northern Ireland rivers leading to increased eutrophication has been reported for the last two decades. To identify if a similar trend could be observed in land drainage waters SR

Loss of organic N in land drainage may contribute to water pollution. This study was conducted to quantify the loss of organic nitrogen in drainage water from grazed grassland (Lolium perenne L. cv. Talbot) swards receiving a range of fertilizer N in

1. Lough Neagh is a large eutrophic lake covering 387 km2 with a mean depth of 8.9 m. It is an important natural resource, being the largest single source of potable water for Belfast, Northern Ireland. 2. This report examines the causes of the year-

Recent studies on Northern Ireland rivers have shown that summer nitrite (NO(inf2)(sup-)) concentrations greatly exceed the European Union guideline of 3 (mu)g of N liter(sup-1) for rivers supporting salmonid fisheries. In fast-flowing aerobic small

Lough Neagh is an important natural resource, being the largest single source of potable water for Belfast. Its catchment area covers about one-third of the land area of Northern Ireland. Six inflow rivers drain 88% of the total catchment, which has

Previous studies have reported that only 40% of nitrite (NO 2 - ) in major rivers in Northern Ireland originates from land drainage. The remainder appears to originate from N transformations at the interface between sediment and water within river sy

The Lough Neagh catchment area covers about one-third of the land area of Northern Ireland. This report documents NO 2 - concentrations in the major rivers entering Lough Neagh, which are frequently in the range of 100 to 150 μg N L -1 and exceed th

The scale and chronology of the phosphorus (P) enrichment of Lough Neagh, a large hypertrophic lake, was assessed using, as enrichment proxies, published palaeocological studies on diatoms and chironomid head capsules preserved in the lake sediments
