New research has found that shrimp like creatures on the South Coast of England have 70 per cent less sperm than less polluted locations elsewhere in the world.
New research has found that shrimp like creatures on the South Coast of England have 70 per cent less sperm than less polluted locations elsewhere in the world. The research also discovered that individuals living in the survey area are six times less numerous per square metre than those living in cleaner waters.
This discovery, published today in Aquatic Toxicology, mirrors similar findings in other creatures, including humans. The scientist leading research at the University of Portsmouth believes pollutants might be to blame, further highlighted by this latest research.
Professor Alex Ford, Professor of Biology, University of Portsmouth, says: “We normally study the effect of chemicals on species after the water has been treated. The shrimp that we have tested are often in untreated water. The study site suffers from storm water surges, which is likely to become more common with climate change. This means that the creatures could be exposed to lots of different contaminants via sewage, historical landfills and legacy chemicals such as those in antifoulting paints. There is a direct relationship between the incidence of high rainfall events and in the levels of untreated sewage.”
