Think of your own circulatory system. You can see some veins in your hands and arms, and feel the pulse in your carotid artery with your finger. But you can’t see the capillaries – tiny channels that support vital processes. Nutrients, o...

Study confirms micro-algae’s cleaning ability in wastewater treatment

Environmental engineers have discovered that Chlorella vulgaris, a single-celled fresh water algae species, effectively removes pollutants from wastewater even at fluctuating levels, making it an effective tool for wastewater treatment. The study, published recently in Water Environment Research, indicates that Chlorella vulgaris continues to remove harmful elements like nitrogen and ...

Rivers Monitoring Programme

Ireland has more than 73,000 km of river channels. If placed end-to-end, they could encircle the Earth almost twice.  Three-quarters of these channels are very small streams that typically flow into larger rivers. The longest and largest river in Ireland is the Shannon. It runs for more than 360 km from its source to the sea and discharges on average more than 200,000 litres of water per second...
