Meiobienthos, alternative indicator of beach pollution
The meiobenthos of sandy beaches was collected with a 2.54 cm diameter nucleator introduced 5 cm into the sediment. Samples were also taken to microbiological analysis of the wet sand of the beaches during the lowest tide of syzygy, every 15 days for a period of two months. The samples were taken at...

| Čoahkkáigeassu: | The meiobenthos of sandy beaches was collected with a 2.54 cm diameter nucleator introduced 5 cm into the sediment. Samples were also taken to microbiological analysis of the wet sand of the beaches during the lowest tide of syzygy, every 15 days for a period of two months. The samples were taken at beaches in the Los Santo region, Los Guayaberos, Bella Vista, El Rincon and La Yeguada. The analysis of the microbiological results indicated that there was growth in Los Guayaberos and Bella Vista of faecal coliforms, while the other two beaches growth is lower or there was no growth. The analysis of the results of the four beaches indicated the following groups associated with polluted areas: Nematodes with 45,2 ind/10 cm², Oligochaets with 6,91 ind/10 cm², Gnathostomulids with 1,97 ind/10 cm², and Foraminiferans with 0,98 ind/10 cm², which represented the 90 % of the meiobenthic fauna. On the other hand, in the uncontaminated zone: Nematodes 12.82 ind / 10 cm², Oligochaetas 4.27 Gnathostomulids 2.63 ind / 10 cm², and no Foraminifera, the highest abundance of these groups is a good indicator of beach pollution. |
