“…Threshold values for the soil matrix were considered to be improper when it had CT and EC levels above 138.44 CFU/g and 17.54 CFU/g, respectively, and for the water matrix when EC levels were above 9.23 CFU/ml. Parasitological analysis of soil samples was performed using the adapted Lutz and Baermann-Moraes Methods (Amaral et al, 2015). After sedimentation, the supernatant discarded, and the pellet preserved in SAF (2.9 ml of acetic acid, 1.5 g of sodium acetate, 4.0 ml of 40% formaldehyde and 92.5 ml of distilled water).…”

The state of Bahia's main climatic characteristic is the high spatial and chronological variability of precipitation. This heterogeneity may be used to determine of pluviometrically homogeneous areas that can define mesoregions in the state, since they allow better management of water resources and help in the elaboration of agricultural studies. The mesoregions already proposed by the scientific community for the state were based only on the annual precipitation in the proximity of the pluviometric stations. In this paper, besides these parameters, spatial and chronological rainfall distribution was considered, i.e., the Precipitation Concentration Degree (PCD) and Precipitation Concentration Period (PCP). The new zoning is based on an update of a study defined in 2000 that divided Bahia into eight mesoregions. Thus, 180 pluviometric stations were distributed throughout the state and grouped conforming to the division previously described. It was concluded that some stations of the same mesoregion had presented conflicting values for the analyzed parameters and, therefore, should not belong to the same area. Starting from an arrangement of the collection stations, considering their proximity, annual precipitation and statistical parameters, a new zoning for Bahia with 10 clusters was defined and validated through the statistical treatment of data.

Doenças de veiculação ambiental de formas infectantes de protozoários e helmintos constituem um grande problema de saúde pública e em medicina veterinária, por afetarem diretamente a saúde do homem e dos animais domésticos. Este estudo teve por objetivo realizar o monitoramento do grau de contaminação parasitológica de areias de parques públicos situados nos municípios de Castelo e Cachoeiro de Itapemirim, Espírito Santo, Brasil. Foi realizada a avaliação da qualidade sanitária das areias do parque Beira Rio, situado na cidade de Castelo -ES e dos parques dos bairros Vila Rica e BNH, locados na cidade de Cachoeiro de Itapemirim -ES, por meio de análises parasitológicas utilizando para isto as técnicas de Hoffman, Willis, Baermann e a técnica de centrífugo-flutuação simples. Das nove amostras de areia seca analisadas pelas técnicas tradicionais foi observada frequência positiva para ovos de ascarídeos, ancilostomídeos, bem como de helmintos pertencentes à superfamília Trichuroidea. Ademais, larvas de Ancylostoma spp. foram recuperadas. Os resultados demonstram elevado índice de contaminação nas areias do parque Vila Rica, e ressaltam a necessidade de implementação de medidas de prevenção e controle por partes dos órgãos públicos que visam à educação sanitária das pessoas e comerciantes que frequentam estes ambientes.Palavras chave: Areia, helmintos, monitoramento da qualidade sanitária, parques públicos, protozoários, saúde pública Sand analysis of public parks in the municipalities of Castelo and

Sanitation actions are rare in the communities of Manguinhos, so evaluation of the sanitary conditions of the river waters and the peridomestic soils of the communities allows the diagnosis of the risk of contamination. This study evaluated coliform levels (total coliforms and Escherichia coli) by the filter membrane method, and parasitological (by adapted Lutz and Baermann-Moraes methods) in the waters and soils of the Faria-Timbó, Jacaré and Canal do Cunha Rivers that pass through the communities of the Territory of Manguinhos, RJ, according to the standards established in Brazilian legislation. In all points of the rivers, the water was unfit, with an average level of Escherichia coli 3,800 times higher than that standardized in CONAMA Resolution No. 274/2000. Larvae, helminths eggs and protozoan oocysts were observed. Soil samples were also unfit, with mean total coliform level 77,000 times higher than that considered acceptable by SMAC Resolution 468/2010. The Escherichia coli average level was 53,000 times higher than that permitted by the legislation. However, helminths eggs were found in only one soil sample. It was concluded that the lack of sanitation in this locality results in the high coliform and parasitological levels of the river waters and in the peridomestic soils, and that immediate modifications are needed to the Brazilian environmental paradigm, which uses its water bodies as sewage disposal ditches.
