  • Nutrients in streams can mask toxic effects of pesticides on aquatic life

    Moderate levels of nitrogen in streams and rivers can make it difficult to assess the effects of pesticides on aquatic wildlife, because nutrients mask the pesticides’ impacts, according to recent research. This highlights the importance of considering nutrient levels when developing measures to protect aquatic ecosystems. Freshwater organisms are exposed to a number of natural and ...

  • Fine-tuned policies needed to limit phosphorus runoff

    New research in Ireland has evaluated two policies designed to reduce phosphorus runoff from agricultural land into water. Data indicate that policies need to be better tailored to specific times and locations, in order to deal with, for example, the impact of seasonal changes and different soil types on phosphorus runoff. Intensive agriculture and high populations tend to transfer ...

  • Catchment plans will be `vital` to tackle pollution

    Catchment management plans will be vital if the UK is to improve water quality and reduce its greenhouse gas emissions, according to environmental scientists. Experts from environmental consultancy ADAS said the plans could help to tackle diffuse pollution at the source. Speaking at the Water Concerns conference, organised by ADAS, experts from the water industry said many traditional end-of-pipe ...

  • Manure runoff depends on soil texture

    Research has documented the rise of nutrient runoff from flat agricultural fields with high rates of precipitation that adds nitrates and phosphates to waterways. These nutrients increase the amount of phytoplankton in the water, which depletes oxygen and kills fish and other aquatic creatures. While injecting animal manure slurry into the soil has been proven to be an effective way of reducing ...
