SUMMARY:Aquatic Fate and Effects of Herders
DESCRIPTION:Poster\n\nKelly Marie McFarlin (ExxonMobil) and Thomas Parkert
 on (EnviSci Consulting)\n\nWhen an oil spill occurs, there are four main o
 il spill response options: mechanical recovery, chemical dispersion, in-si
 tu burning and natural attenuation. In-situ burning is the controlled inci
 neration of a surface oil slick. Ignition of a floating oil slick can only
  occur if the slick’s thickness is ≥ 2 mm due to the massive heat loss tha
 t occurs with the underlining seawater. Booms and chemical herding agents 
 can be used to corral oil to achieve the required thickness. We conducted 
 a comprehensive literature review to document the state-of-science surroun
 ding the environmental fate and biological effects of herders, identified 
 research needs and developed new data to address knowledge gaps. Main know
 ledge gaps were noted around the need for establishing acute toxicity thre
 sholds for the two chemical herders listed in the USEPA National Contingen
 cy Plan Project Schedule: THICKSLICK 6535 and SILTECH OP-40 and evaluating
  chronic toxicity thresholds. Knowledge gaps were addressed by performing 
 standardized chronic toxicological testing on algae and Ceriodaphnia dubia
  using internationally recognized protocols. This poster will summarize th
 e chemical and physical properties of THICKSLICK 6535 and SILTECH OP-40, i
 ncluding their biodegradation potential, bioaccumulation and aquatic toxic
 ity to over 30 different aquatic species. These data will provide an envir
 onmental realistic hazard assessment to assist steak holders with communic
 ating the environmental risks of chemical herder application for in-situ b
 urning.\n\nTag: Preparedness, Prevention, Remediation, Response, Restorati
