Oil Spill Begins To Wash Ashore

This video attests to the oil slick moving ashore AND to disbursement chemicals being used and "hiding" the oil. (How much remains broken up so as to be less visual, but present in tiny molecules?) So the people, fish, and birds have to contend with both oil and chemicals -- what are these chemicals? What is the short term and long term effects and what will BP do about it going forwards as it privatizes its profits and socializes most of their cleanup costs -- $750 million will not go very far, especially with oil still gushing. Is this America's Chernobyl?
