“…Investigations on soil contamination by parasites in public places constitute an important part of public health studies because of the possibility of zoonosis transmission (SILVA et al, 2009). Thus, the aim of the present study was to investigate occurrences of parasite forms in soil samples collected from a student environment in the South of the State of Rio Grande do Sul.…”

Environmental contamination by parasite forms was studied on a university campus in the municipality of Pelotas, Rio Grande do Sul. Soil samples were analyzed using the modified Caldwell & Caldwell technique to identify parasite forms. Nematode eggs were detected in 62% of the samples. Among the parasites detected, eggs of Toxocara spp. and Ancylostomatidae were the most prevalent parasites in the studied area throughout the study period. The results demonstrated that there is significant environmental contamination, thereby representing a risk of zoonotic infection for humans frequenting the study area.

“…Soil and water are considered important sources for transmission of vectors that cause diseases in humans and animals. Diseases related to contaminated soil, for example, are ascaridiasis, tricuriasis, visceral and cutaneous larva migrans (Silva et al, 2009). The most water-related diseases are giardiasis, amebiasis, acute diarrheal disease (Brasil, 2015) and cryptosporidiasis (Mons et al, 2009 The present work reports the sanitary conditions 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.…”

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.

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.
