Effects of a crude oil spill on water quality and macrobenthos of a southeast Texas stream

  title={Effects of a crude oil spill on water quality and macrobenthos of a southeast Texas stream},
  author={Richard C. Harrel},
On December 6, 1981 an oil spill of 160 barrels (25 440 liters) occurred in a small southeast Texas stream. Water quality changes, other than the presence of oil, were not evident until six months later when water temperature increased and stream flow ceased. This resulted in decreased dissolved oxygen and increased carbon dioxide concentrations. Responses of the benthic macroinvertebrate community included an increase in density of oligochaetes, decrease in numbers and taxa of chironomids… CONTINUE READING
