Levels of persistent organochlorine pesticides (OCPs) and polychlorinated biphenyls (PCBs) were determined in the blood serum of people living and working in the urban area of greater Rio de Janeiro city. Blood samples from 33 volunteers (16 males, 17 females, 19-63 years old) were taken in January 1999. OCP residues (op'DDT, pp'DDT, pp'DDD, pp'DDE, Aldrin, Dieldrin, Endrin, Heptachlor, Heptachlor-epoxide, alpha-, beta- and gamma-Hexachlorocyclo-hexane, Hexachlorobenzene) and PCBs (congeners: 28, 52, 101, 138, 153, 180) were extracted with n-hexane and analyzed by gas chromatography with electron capture detection. Except for pp'DDE (detection limit = 1.4µg/L) no other OCP residue was found in the samples. No PCB congener (detection limit = 2.0µg/L) was detected either. pp'DDE was found in 17 out of 33 samples in concentrations that ranged from 1.4 to 8.4 µg/L of serum or, on a fat basis, from 0.200 to 3.452 µg/g of serum lipids. Percentage of positive samples (%) and levels of pp'DDE (range of positive samples) increased from the youngest to the oldest group (<=29 yrs: 10%, 0.278µg/g; 30-39 yrs: 60%, 0.200-0.765µg/g; > or = 40 yrs: 77%, 0.257-3.452µg/g).

Abstract Spatial and temporal distribution patterns of the warrior swimming crab Callinectes bellicosus fishery in the Mexican Pacific were investigated. Geo-referenced commercial trap capture data derived from 44 trips in the Bahia Magdalena were analysed. Three fishing zones (Z1, inner; Z2, middle; Z3, mouth of the bay) and two climate seasons (warm, July-December; and cold, January-June) were defined previously. There were 1099 traps in Z1, 715 in Z2 and 2111 in Z3; in the warm season, 2091 traps were checked, whereas 1834 were checked in the cold season. The average number of individuals per trap (CPUE) varied by sex, zone and season, however, male crabs always predominated. During the warm season, large males (CW > 115 mm) exhibited the greatest value of CPUE. On average, the males represented 77% during the warm season and 84% during the cold season. The average size of the males (125 ± 0.843 mm CW) was significantly higher than the average size of females (121 ± 1.140 mm CW). The catch was composed of large mature males but females were absent in Z1; in comparison, both large mature males and females, in addition to ovigerous females, composed the catch at the mouth of the bay (Z3). Crab abundance was notably reduced in the cold season, especially for female crabs. The temporal behaviour of the warrior swimming crab in Bahia Magdalena is similar to that reported from the coastal lagoons of the Gulf of California; however, the low presence of females throughout the year could be related to their preferred environmental conditions, which include deeper areas with more current circulation, like those that occur at the mouth of the bay. These data corroborate the necessity to interpret with caution the crab population dynamics solely based on results derived from fishing with traps in coastal lagoons.

This research proposes an environmental quality indicator to detect, predict and scientifically evaluate the environmental impact generated by chemical substances within the pollutant group of nonsteroidal anti-inflammatory drugs (NSAIDs) that are categorized as emerging contaminants (ECs) with endocrine disruptive action. The present study was carried out in two coastal lagoons affected by wastewater produced by urban and rural settlements in the states of Colima and Jalisco. Four pharmaceutical compounds were analyzed: diclofenac, ibuprofen, ketorolac and naproxen. The muscle tissues of 14 fish species were analyzed; all had measurable concentrations of the four contaminants. The presence of the ECs was confirmed in all the samples collected. The bioaccumulative potential risk (BPR) of the ECs is estimated by calculating the environmental risk factors and the potential risks to human health, evaluating the concentration and assessing the risk involved in the incorporation of the pollutants into the environment. The BPR indicates the potential impact of NSAIDs on the ecology of these coastal lagoons, and predicts whether a contaminant is likely to act and persist in the environment and bioaccumulate in organisms. Additionally, it estimates the possibility of contamination and risks to human health caused by residues of the chemical contaminants.

A New Species

A new species of Laeonereis from a shrimp farm associated with a subtropical coastal lagoon on the Mexican Pacific coast is described. The new species is characterized by a deep anterior groove on the prostomium, which is shared only with L. culveri. However, longer tentacular cirri extending back to the anterior margin of chaetiger two, the number of papillae of each group on the maxillary ring of the pharynx, and the relative size of the homogomph falcigers in the new species, allow us to separate the two species. Although the species has not been previously detected in the coastal lagoon surrounding the shrimp farm, we postulate that L. watsoni n. sp. is likely to be part of the invertebrate communities of the upper parts of similar coastal lagoons that are common along the tropical coasts of Mexico.
