Hydrocarbon and Organochlorine Residue Concentrations in Sediments from. The length and width of cchetumal, as well as the diameter of the gametangia were clearly different for both species.
Twenty grams of silica gel were sluny-packed in methylene Table 1. Bioassays as a tool for contamlnacion toxicology. Hydrocarbon and chlorinated organic compound concentrations were determined according to procedures described in Sericano et aL and Wade et al.
Dasycladaceae in a polluted coastal lagoon Chetumal Bay, Mexico. February 9 to June As part of an integrated effort to diagnose this mass mortality, the concentrations of organic pollutants in the sediments of cheyumal bay were determined. Las diferencias en estrategias reproductivas probablemente ayudan a que B. Redescriptions and reestablishments of some species belonging to the genus Prionospio Polychaeta, Spionidae and descriptions of three new species VH Delgado-Blas Helgoland marine research 68 1, It is located between 18 21′ and 18 52′ N, and 87 54′ and 88 23′ W.
The organic compounds were separated and quantified by gas chromatography using a Hewlett Packard Series I1 gas cromatograph equipped with a 30 m x 0. The highest concentrations, for all hydrocarbon fractions, were observed in station 17, at the northeast of the Bay.
Funding for sustainable Open Access incl. The methylene chloride extract was concentrated from approximately mL to 20 mL in a flat-bottomed flask equipped with a three- ball Snyder column bshia and then it was mixed with the hexane extract. The median concentrations of unresolved hydrocarbons is very similar to those of aliphatics 4.

It is connected to the Caribbean Sea through a shallow 19 krn opening. The contaminacioj fraction was also concentrated and then transferred to a Kuderna-Danish tube bahla concentrate the extract to a final volume of 2 mL using a continuous stream of nitrogen. Median concentration of total PCBs was 2. Acute toxicity and risk assessment of three commercial detergents using the polychaete Capitella sp.
