Tokyo, Japan – Researchers from Tokyo Metropolitan University have studied how polymer-coated fertilizer (PCF) applied to fields ends up on beaches and in the sea. They studied PCF deposits on beaches around Japan, finding that only 0.2% of used PCFs are washed into rivers and returned to the coastline. When there are canals connecting fields to the sea, this rises to 28%. Their findings highlight a potentially significant “sink” in the global circulation of plastics.
Canada is failing in a decades-old pledge to monitor the health of Pacific salmon, according to new research from Simon Fraser University.
At a time when government policy is geared towards accelerating industrial development across sensitive B.C. watersheds, an SFU study published today in the Canadian Journal of Fisheries and Aquatic Sciences reports that monitoring of salmon spawning populations has dropped 32 per cent since Canada adopted its Wild Salmon Policy 20 years ago.
Two studies led by an opioid treatment program run by the University at Buffalo and UBMD Emergency Medicine have found that harm reduction vending machines installed across New York State are well utilized and provide critical, lifesaving services to high-risk individuals who might not otherwise have access.
