Soil pH influences the toxicity of Basamid® eluates to non-target species of primary consumers.

Basamid® is a fumigant nematicide and fungicide known to break down in several volatile compounds, mainly methyl isothiocyanate (MITC), when in contact with water. Soil abiotic parameters, such as pH, influences this breakdown process, and thus, the toxic effects of Basamid® to aquatic biota. This work studied the influence of soil pH (5.

Ecotoxicity of eluates obtained from Basamid® contaminated soils is pH dependent: A study with Hydra viridissima, Xenopus laevis and Danio rerio.

Agrochemicals are mostly used to deplete pests and treat diseases in terrestrial agro-ecosystems. However, their transport through the soil, by leaching and/or runoff, may cause them to reach aquatic systems. Environmental parameters, such as soil pH, can affect this transport, by influencing the magnitude of agrochemicals degradation and chemical reaction.

Soil pH matters in the ecotoxicity of Basamid® to freshwater microalgae and macrophytes.

Intensive agriculture along with the use of agrochemicals has been associated with low soil fertility, soil erosion, and soil acidity. Management of soil pH through liming is a common practice in agriculture to increase soil fertility and nutrient availability. When altering soil pH, different chemical reactions occur depending on soil composition and agrochemicals presence.

Feeding exposure and feeding behaviour as relevant approaches in the assessment of the effects of micro(nano)plastics to early life stages of amphibians.

The sedimentation of micro and nanosized plastics is of considerable environmental relevance and the need to assess its sublethal effects to biota increasingly recognized. In their majority, as bottom, non-selective grazers, independent-feeding young life stages of amphibians, an already severely endangered worldwide group, may be particularly vulnerable to sedimented plastics. Alongside, they may be good model organisms for the assessment of the effects of micro(nano)plastics (MNPs) through ingestion.

Representativeness of Folsomia candida to assess toxicity of a new generation insecticide in different temperature scenarios.

Climate change may interfere with the behavior of pesticides and organisms, influencing pesticides toxicity to non-target organisms like collembolans. Aiming to assess the representativeness of the standardized species F. candida to the Collembola group under different temperatures, four species of collembolans - Folsomia candida, Folsomia fimetaria, Proisotoma minuta and Sinella curviseta - were exposed to a new generation insecticide of Chlorantraniliprole, under the standardized temperature of 20 °C, and a temperature foreseeing a global warming scenario of 25 °C.

Effects of Long-Term Exposure to Increased Salinity on the Amphibian Skin Bacterium Erwinia toletana.

Amphibian's skin bacterial community may help them to cope with several types of environmental perturbations, including osmotic stress caused by increased salinity. This work assessed whether an amphibian skin bacterium could increase its tolerance to NaCl after a long-term exposure to this salt. A strain of Erwinia toletana, isolated from the skin of Pelophylax perezi, was exposed to two salinity scenarios (with 18 g/L of NaCl): (1) long-term exposure (for 46 days; Et-NaCl), and (2) long-term exposure followed by a recovery period (exposure for 30 days to NaCl and then to LB medium for 16 days; Et-R).

An integrated view of redox and catalytic properties of B-type PpDyP from Pseudomonas putida MET94 and its distal variants.

PpDyP from Pseudomonas putida MET94 is an extremely versatile B-type dye-decolourising peroxidase (DyP) capable of efficient oxidation of a wide range of anthraquinonic and azo dyes, phenolic substrates, the non-phenolic veratryl alcohol and even manganese and ferrous ions. In reaction with H2O2 it forms a stable Compound I at a rate of (1.4±0.
