Pesticide Occurrence in Selected South Florida Canals and Biscayne Bay during High Agricultural Activity

Climate and soil conditions in South Florida along with an extensive canal system facilitate movement of agricultural pesticides into surface waters. In a two-year study (2002-2004) of the currently used pesticides in South Florida, atrazine, endosulfan, metolachlor, chlorpyrifos, and chlorothalonil were the most frequently detected in the canals and in Biscayne Bay, with average concentrations of 16, 11, 9.0, 2.6, and 6.0 ng/L, respectively. Concentrations of atrazine and chlorpyrifos were highest near corn production. Chlorothalonil and endosulfan concentrations were highest near vegetable production, with no clear trend for metolachlor, which is used on multiple crops. Concentration data were used to calculate an aquatic life hazard potential for the planting period (November) versus the harvest period (March). This analysis indicated that a higher hazard potential occurs during harvest, primarily from the use of endosulfan. These data will also serve to document canal conditions prior to implementation of the Comprehensive Everglades Restoration Plan (CERP)

King Hu and Run Run Shaw: The Clash of Two Cinema Legends

King Hu is revered as one of the most influential film-makers of Chinese cinema. Run Run Shaw is the legendary tycoon behind the renowned media kingdom Shaw Brothers. After Hu joined Shaw Brothers in 1958 as an actor, it was Shaw who offered Hu his first career opportunities to write and direct.
