Foram testados os efeitos, in vitro, de 160, 320, 640, 1280 e 2560 mg/L do óleo essencial (OE) de Lippia alba contra Anacanthorus spathulatus, Notozothecium janauachensis e Mymarothecium boegeri das brânquias de tambaqui. 1280 mg/L e 2560 mg/L mostraram 100% de eficácia in vitro após 20 minutos de exposição ao OE, enquanto nas menores concentrações a eficácia foi após 2-3 h. Nos controles a mortalidade ocorreu em 9 h. Em seguida, 240 alevinos de tambaqui Colossoma macropomum (11,0±1,0 cm e 44,0±10,0 g) foram distribuídos em 4 tratamentos (20 peixes por repetição) e 3 repetições nos banhos com 100 e 150 mg/L de OE, durante 30 minutos e a eficácia contra Ichthyophthirius multifiliis foi 40,7% e 50,3% em peixes expostos a 100 e 150 mg/L do OE, respectivamente. Para monogenoideas houve eficácia de 14,0% somente nos peixes expostos a 100 mg/L do OE, que tiveram aumento de glicose plasmática e variações nos níveis de proteínas totais, hemoglobina, hematócrito, número de eritrócitos, trombócitos e leucócitos sanguíneos e severas alterações histopatológicas nas brânquias. Óleo essencial de L. alba mostrou grande potencial no tratamento antiparasitário in vitro contra monogenoideas e eficácia in vivo contra protozoários I. multifiliis. |

Sewage sludge contains plant nutrients and organic matter in its composition, making it a potential partial substitute for mineral fertilizers if it meets environmental, agronomic, and sanitary standards. The objective was to evaluate the content of nutrients and heavy metals in the sludge generated in four wastewater treatment stations (WWTPs) in Rio de Janeiro state and assess its potential value and usefulness. The samples of 19 batches from the WTTPs Alegria, Barra da Tijuca, Ilha do Governador, and Sarapuí were analyzed. The WWTPs differ in methods and processes used for treating sewage and sludge. The total contents of C, N, P, K, Ca, Mg, Fe, Al, Na, Co, Mn, As, Ba, Cd, Cr, Cu, Ni, Se, Pb, and Zn were evaluated, as well as the ratio C/N, pH, organic matter content, and electrical conductivity. The grouping of sludge samples was assessed using principal components (PCA) and cluster analysis. The economic valuation of sludge was conducted utilizing the substitute goods method, which compared the sludge’s N-P-K contents with the prices of consolidated nutrient sources. All the evaluated sludge batches exhibited concentrations of heavy metals below the limits allowed by Brazilian law, along with high levels of nutrients and organic matter. Considering the chemical characteristics, all evaluated materials showed potential for agricultural use, but it is crucial to evaluate the microbiological characteristics of sludge batches before agriculture application. PCA and cluster analysis demonstrated that sludge samples from the same WWTP clustered close to each other, demonstrating higher similarity among themselves than with samples from other WWTPs. The sludge had an average added value of U$ 88.46 per megagram, considering the total contents of N, P, and K in its composition. Land application of sewage sludge can reduce the need to purchase mineral fertilizers, thereby supporting the feasibility of reusing this material in the agricultural sector.
