Soil toxicity in a protected area in Brazil: Cytotoxic, genotoxic, and toxic effects.

The Campos de Palmas Wildlife Refuge (CPWR) (Brazil) is a full protection Conservation Unit (CU) formed by private properties, where the use of land and natural resources are allowed sustainably according to the rules of the CU Management Plan. Inadequate practices of land use and occupation within this CU can affect its quality and the organisms that depend on them. Considering the above, the objective of the present study was to biomonitor different land uses and occupations within the CPWR and its surroundings, during the four seasons of a year, using the bioindicators Allium cepa (cytotoxicity and genotoxicity tests) and Eisenia fetida (leakage test).

Biomonitoring of surface water quality in the Chopim River within the Conservation Unit Campos de Palmas Wildlife Refuge, southern Brazil.

The Campos de Palmas Wildlife Refuge (RVS-CP) is a full protection conservation unit (CU) formed by private properties. The present study aimed to use the bioindicators Allium cepa L. (cytotoxicity and mutagenicity tests) and Eisenia fetida (avoidance test) to assess the quality of surface water of the Chopim River within the RVS-CP area and its surroundings during the four seasons of the year.

Allium cepa L. as a bioindicator to measure cytotoxicity of surface water of the Quatorze River, located in Francisco Beltrão, Paraná, Brazil.

Due to an increase in water consumption in the industrial sector and within the Brazilian population, surface water that receives wastewater from industries, domestic sewage, agricultural industries, and sewage treatment stations can pollute water bodies when not properly treated. The water quality has been linked to catchment characteristics and intensity of agricultural activities. Thus, the aim of this study was to monitor the cytotoxic potential of the water of the Quatorze River, located in the town of Francisco Beltrão, Paraná, Brazil, along its route in the rural area, using the root meristematic cells of Allium cepa L.

Comparative studies among 4 (four) different methods of total lipids extraction were carried out to evaluate the lipid extraction efficiency and fatty acids contents in cow milk. Total lipids extraction methods were Bligh e Dyer (BD), Folch et al.
