Effects of methylenedioxypyrovalerone (MDPV) in avoidance behaviour and reprodu...
Ribeiro, O.; Ferreira, J.; Sousa, J. R.; Natal-da-Luz, T.; Ribeiro, C.; Carrola, J. S.Background: The excessive use of psychoactive substances (PAS) is a global problem that directly and indirectly affects human, animal health and environment [1], related with “one health” concept. These substances and their metabolites enter in the wastewater through human excretion and consequently into water systems. The sewage sludge produced in wastewater treatment plants can be used as amendment in agricul...
Lead acetate ecotoxicity in tropical soils
Alexandrino, R. C. S.; Lima, F. R. D.; Martins, G. C.; Natal-da-Luz, T.; Sousa, J. P.; Guilherme, L. R. G.; Marques, J. J.Lead acetate (AcPb) is an important raw material used in chemical industries worldwide. The potential toxicity of AcPb is generally attributed to the presence of Pb. However, the effect of AcPb on the environment as a whole is still poorly known. This study aimed to evaluate AcPb toxicity on three standard species of soil invertebrates and two plant species using ecotoxicology tests. Three tropical soils (Oxiso...
Recycling organic wastes to agricultural land as a way to improve its quality: ...
Alvarenga, P.; Palma, Patrícia; Mourinha, C.; Farto, M.; Dores, J.; Patanita, M.; Cunha-Queda, C.; Natal-da-Luz, T.; Renaud, M.; Sousa, J. P.A field study was established to assess the effects of a sewage sludge (SS), a mixed municipal solid waste compost (MMSWC) and a compost produced from agricultural wastes (AWC), in a Vertisol, using Lolium multiflorum L The amendments were applied for two consecutive years: 6, 12 and 24 t dry matter ha(-1) for SS, and the amendment doses for MMSWC and AWC were calculated to deliver the same amount of organic ma...
Organic wastes as soil amendments – Effects assessment towards soil invertebrates
Renaud, M.; Chelinho, S.; Alvarenga, Paula; Mourinha, C.; Palma, Patrícia; Sousa, J.P.; Natal-da-Luz, T.; Palma, Patrícia; Alvarenga, PaulaUsing organic wastes, as soil amendments, is an important alternative to landfilling with benefits to soil structure, water retention, soil nutrient and organic matter concentrations. However, this practice should be monitored for its environmental risk due to the frequent presence, of noxious substances to soil organisms. To evaluate the potential of eight organic wastes with different origins, as soil amendme...
Boric acid as reference substance: pros, cons and standardization
Amorim, M. J. B.; Natal-da-Luz, T.; Sousa, J. P.; Loureiro, S.; Becker, L.; Römbke, J.; Soares, A. M. V. M.Boric acid (BA) has been successfully used as reference substance in some standard test guidelines. Due to the fact that previously selected reference substances present a significant risk to human health and/or are banned for environmental reasons, BA is being discussed for broader adoption in OECD or ISO guidelines. To provide input on BA data and contribute to the discussion on its suitability as a reference...
