TI  - Analysis of organochlorine pesticides in coral (Porites evermanni) samples using 
      accelerated solvent extraction and gas chromatography/ion trap mass spectrometry.
PG  - 211-8
AB  - A gas chromatography/ion trap mass spectrometry method was developed for analysis 
      of organochlorine pesticides (OCPs) in coral samples, which were extracted with 
      accelerated solvent extraction (ASE) and cleaned up on a sulfuric acid-modified 
      silica gel column. The optimal ASE conditions were found to be 100 degrees C and 
      2000 psi, with a mixture of acetone and methylene chloride (1:1, v/v). The target 
      analytes include hexachlorocyclohexanes (HCHs, specifically, alpha-, beta-, 
      gamma-, and delta-HCH isomers), heptachlor, and hexachlorobenzene (HCB), o,p'-, 
      p,p'-dichlorodiphenyltrichloroethane (o,p'-, p,p'-DDT), o,p'-, 
      p,p'-dichlorodiphenyl-dichloroethylene (o,p'-, p,p'-DDE), and o,p'-, 
      p,p'-dichlorodiphenyldichloroethane (o,p'-, p,p'-DDD). Standard sand samples were 
      used as an alternative matrix spiked with OCP standards to determine the method 
      precision and accuracy. Average recoveries of OCPs ranged from 82% to 102%, with 
      relative standard deviations (RSDs) of 3%-6%, at a level of 10 ng/g and from 50% 
      to 68%, with RSDs of 13%-19% at a level of 2 ng/g. The developed method was 
      applied for analysis of OCPs in coral samples collected from Tern Island and 
      Bikini Atoll in the Pacific Ocean. The concentrations of HCB were 7-26 pg/g dry 
      weight in the samples from Bikini Atoll and 3-45 pg/g in those from Tern Island, 
      and heptachlor concentrations were 208-2200 and 44-104 pg/g in the coral samples 
      from Bikini Atoll and Tern Island, respectively. (summation operator)HCH (sum of 
      alpha-, beta-, gamma-, and delta-HCH) were 8-82 pg/g in Bikini Atoll coral and 
      86-629 pg/g in Tern island coral, and (summation operator)DDT (sum of o,p'-, 
      p,p'-DDD, o,p'-, p,p'-DDE, and o,p'- p,p'-DDT) were 80-212 pg/g in Bikini Atoll 
      coral and 593-3165 pg/g in Tern Island coral. The results suggest that coral is a 
      viable indicator species for pollution monitoring, which pollutants and their 
      concentrations may be related to dated carbonate layers.
