“…In the Municipality of Lages, this natural resource is at risk of contamination due to irregular occupation, lack of urban planning, drainage of untreated effluents and inappropriate waste disposal in the areas of outcrop and recharge of the aquifer. 23 Although the present study has shown a low percentage of participants discarding leftovers and medications, including antibiotics in the toilet / sink, the medicines drugs can reach rivers and streams that seep into the city, infiltrate soil and aquifers. Since only about 25% of the population of Lages is served with sanitary sewage and 40% of the sewage collected is treated, so many drug residues can contaminate surface and groundwater.…”

The study objective was to obtain information on the practices adopted by the students of the High School of Course technical of Environmental Sanitation and Biotechnology of Cedup Renato Ramos da Silva School, in Lages, SC for the disposal of residues of medicines and household cleaners in their homes. This study was developed by students of scientific initiation of High School (PIBIC/EM). For data collection a semi-structured questionnaire was applied to the students of the respective courses during the period of their classes in the Institution. It was observed that 63% do not have knowledge about the correct procedure of disposal of drug residues and 55.6% still discard the expired drugs in the common trash. Regarding household cleaning products, 90.1% of the participants do not know how to dispose of these residues in their homes, despite frequent use (83.8%). Concerning residues of insecticides, rodenticides and repellents, about 50% of the participants discard the waste in the common bin and 44% do not know how to dispose of these products. Overall, this study showed that High School students from the Environmental Sanitation and Biotechnology technical Course inappropriately dispose of the drug residues and sanitary household products in their homes. Thus, it emphasizes the importance of including the topic about waste management in basic education courses.

“…These results already reflect the effects of the irregular urban expansion studied by MAZZOLLI and EHRHARDT-BROCARDO (2013). It is necessary to develop planning strategies, especially preventive ones that take into account the use and occupation of the soil.…”

“…Agricultural and urban activities can irreversibly contaminate environmentally sensitive areas. A significant recharge area of the Guarani Aquifer is located in housing and industrial districts in Lages, but the municipality still lacks planning policies to preserve this important water resource (MAZZOLLI and EHRHARDT-BROCARDO, 2013).…”

Potentially toxic metals of vegetable gardens of urban schools in Lages, Santa Catarina, Brazil

Urban environments are contaminated in many ways with persistent organic and inorganic pollutants as a result of anthropogenic activities, endangering human health and natural resources. The objective of the present study was to evaluate the soil contamination by cobalt (Co), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) in 10 vegetable gardens of urban schools located near or on Botucatu sandstone outcrops of Guarani Aquifer in the urban areas of Lages, Santa Catarina, Brazil. In each garden, three soil samples at each position (in the soil immediately outside and the soil in the garden) were collected at a depth of 0-20 cm. The ISO 11466 method was used to extract the metals. Inductively coupled plasma optical emission spectrometry was used to quantify the elements and certified materials to evaluate the quantities (SRM 2709a - San Joaquin Soil - NIST). To evaluate the data, principal component analyses and cluster analyses were performed. The cluster analysis for the evaluated metals showed that the highest contents of elements were reported in three gardens. Values above the prevention value defined by resolution no. 420/2005 of the National Council for the Environment -Conselho Nacional do Meio Ambiente (CONAMA) - were reported for cobalt in one garden and copper in three gardens; thus, these areas were categorized as Class III areas. Principal component analysis explained 74.7% of the data and showed the enrichment of some elements within gardens.
