A deadly poison created by mixing sunlight and oil in shallow water

While a huge body of enquiry has been done on the huge petroleum spill in the Gulf Coast , another , small , spill in the San Francisco Bay has shown not only that we do n’t make out much about how dissimilar types of oil colour behave in the environs — but also that they can interact in ways we did n’t predict .

In 2007 , the ship Cosco Busan spilled dugout oil — a compounding of diesel and residual fuel fossil oil — into the San Francisco Bay , contaminating herring - spawn habitats . While in the deeper water , the herrings were make with the expected heart defects result from non - deadly petroleum doses — problems which exist in their universe to this day — but where the water was less than one meter rich , there was a major spike in dying .

The sand trap oil had a issue of unknown components to it — and one of these chemical substance interacted with the sun in the shallow water system , becoming rapidly more toxic . This , in turn , caused the eggshells to rupture ad libitum ( like in the picture above ) . So even if a sand trap oil spill has a much lower book than a blunt oil spill , it can have a much high impact — and shallow water , with sunlight reacting with the oil , can make matter much worse .
