Biochar application can improve soil quality, but at high rates may cause negative effects on soil organisms such as earthworms. Conversely, as ecosystemengineers and catalysts of microbial activity, earthworms can also affect soil quality and interact with biochar, though little is knownconcerning endogeic earthworm species interactions with biochar. Hence, a standard ecotoxicological laboratory trial was undertaken to assess the impact of Brazilnut husk biochar application (0, 2.5, 5 and 10% w/w) on the endogeic cosmopolitan species Pontoscolex corethrurus, and the effects of bioturbation and gut passage on biochar chemical characteristics (assessed using pyrolysis coupled with gas chromatography and mass spectrometry) and morphology (evaluated using scanning electron microscopy). Biochar addition up to 10%w/whad no negative effects on P. corethrurus, and ingested biochar particles showed signs of physical degradation and bacterial colonization. Nine pyrolysis-produced chemical biomarkers (phenolic and aromatic compounds)were detected that can be used as indicators of biochar presence in soils and earthworm castings. Earthworm casts showed distinct macromolecular chemical signatures compared with uningested artificial soil with and without biochar. Earthworm bioturbation and biochar ingestion may have important effects on functionalization and biochar chemical and physical properties that should be considered in field applications, especially where endogeic biochar-consuming species are present.

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.
