“…Por outro lado, a presença de purê aumenta a condutividade quando comparado ao carvão de malte. Como os fertilizantes mais utilizados no cultivo das batatas contêm sulfato de potássio (K 2 SO 4 ) (Campora, 1994), sugere-se que o aumento da condutividade provém da presença do mesmo, uma vez que, presente no meio ele pode exercer papel de aceptor de elétrons, principalmente na ausência de oxigênio (Westphalen et. al., 2016) A adição de ferro ao carvão resultou em um aumento da condutividade, porém houve uma queda no pH.…”

“…al., 2016) A adição de ferro ao carvão resultou em um aumento da condutividade, porém houve uma queda no pH. O aumento na condutividade pode ser decorrente da inserção de ferro ter sido acompanhada do íon sulfato (Westphalen et. al., 2016), e a queda de pH decorrente da introdução de grupos ácidos na superfície do carvão (Boehm,1994).…”

“…This result presents an interesting question: why would the A. aegypti oviposition preference for container organic matter concentration differ between indoor and outdoor environments? One potential explanation is that A. aegypti larvae have been reported to inhabit several types of domestic containers such as toilet seats, rain water containers, water boxes (common in Brazilian houses), and potable water tanks (Forattini & Brito, 2003), and water from these sources typically contains low organic matter concentration (Westphalen et al ., 2016). Despite this, the quantity and diversity of water-holding containers for mosquito offspring development indoors are likely lower than in outdoor environments.…”

The establishment of an invasive species depends on reproductive success and dispersion capability in the new environment. One of the striking examples of invasion in urban environments is the mosquito Aedes aegypti Linnaeus, 1762 (Culicidae). The success of this species is primarily attributed to its ability to colonize urban environments, and some of the important adaptive strategies associated with this ability is the preference for humans as a blood source and intense occupation of residential (indoor) environments. This study evaluated the effects of location (indoor vs. outdoor) and water nutrient level (% organic matter) on the oviposition preference of A. aegypti in an urban environment. We used oviposition choice experiments to evaluate mosquito oviposition in containers holding 1:1 vs 1:0 ratios of water: organic matter placed indoors and outdoors. Eggs were sampled once per week for nine weeks. Our results revealed a strong oviposition preference for outdoor containers, with a significant preference for containers with higher concentrations of organic matter during the fifth to ninth weeks. However, mosquitoes occupying indoor environments did not prefer to lay eggs in containers with lower levels of organic matter. A better understanding of the preferences of A. aegypti regarding the nutrient level and location of oviposition containers can increase our understanding of the behavioral factors allowing mosquitoes to utilize anthropogenic environments.

“…O uso e acesso à água potável, por exemplo, podem ser mediados e facilitados por novas e mais acessíveis tecnologias de tratamento, como o uso de carvão ativado biologicamente ou de membranas com biofilmes para a remoção de resíduos de fármacos. 14 "A busca de uma sociedade e civilização sustentáveis é o desafio que tem sido reconhecido pela nossa geração e necessitará ser atingida por todas as gerações no futuro. Estes desafios estão no âmago dos objetivos do desenvolvimento sustentável da ONU.…”

The Anthropocene, the geological force of the humankind or The Age of Humans implies new processes of reflection on the complexity of our environmental and planetary reality. The discussion on the concept of Anthropocene and its consequences in the academy, in teaching and society should emerge on us a necessary process of a dialogue between different knowledges and an environmental contextualization in teaching chemistry. In this article, we propose a reflection in relation to the environmental education and teaching chemistry in this scenario in three topics: a) the environmental education and the Anthropocene, b) the Anthropocene and environmental chemistry and c) teaching chemistry and Anthropocene. The relationships among the planetary complexity, the environmental education and social learning are arisen for the discussion on Anthropecene, as well as the approach of planetary limits in teaching Chemistry. In the context of teaching Chemistry and the Anthropecene, three topics were selected for didactic planning classes that have already been used for regular and young-adults high schools in the state of Rio de Janeiro, which were: a) green house gases, global warming and teaching Chemistry, b) urban solid wastes and teaching chemistry and c) plastics and teaching Chemistry.
