Abstract
Fruit ripening is a natural, irreversible process crucial for developing luscious flavor and appealing appearance. Fruits are lauded for their health benefits, forming a key part of a balanced diet. Regrettably, the continued use of calcium carbide (CaC2) to ripen fruit persists in various regions due to its low cost and perceived effectiveness. This method raises significant concerns about health, safety, and the resultant fruit quality and flavor. CaC2 and CaC2-ripened fruits contain harmful substances like inorganic arsenic and phosphorus hydrides, posing considerable health risks including chronic toxicity upon consumption or exposure to acetylene released during CaC2 application. Ensuring food safety requires adherence to regulatory standards governing harmful substances in food. Thus, understanding the risks of consuming CaC2-ripened fruit is crucial for crafting strategies to protect consumers' nutritional well-being and food safety. This review presents a comprehensive analysis of the impacts and apprehensions regarding use of CaC2 as a ripening agent in fresh fruit.

Abstract
Calcium carbide, a stable solid compound composed of two atoms of carbon and one of calcium, has proven its effectiveness in chemical synthesis, due to the safety and convenience of handling the C≡C acetylenic units. The areas of CaC2 application are very diverse, and the development of calcium-mediated approaches resolves several important challenges. This Review aims to discuss the laboratory chemistry of calcium carbide, and to go beyond its frontiers to organic synthesis, life sciences, materials and construction, carbon dioxide capturing, alloy manufacturing, and agriculture. The recyclability of calcium carbide and the availability of large-scale industrial production facilities, as well as the future possibility of fossil-resource-independent manufacturing, position this compound as a key chemical platform for sustainable development. Easy regeneration and reuse of the carbide highlight calcium-based sustainable chemical technologies as promising instruments for total carbon recycling.

Toxicity evaluation of vinasse and biosolid samples in diplopod midgut: heat shock protein in situ localization. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2017; 24:22007-22017.

Abstract
Large amounts of residues generated by agricultural, urban and industrial activities are dumped daily on the soil. This practice deserves special attention because it causes serious environmental problems. This study evaluated the toxic potential of the sugarcane vinasse, a by-product of the sugar-alcohol industry, and the biosolid, a residue produced by wastewater treatment plants, both widely used as fertilizers. The evaluation was performed through bioassays using a typical soil bioindicator, the diplopod Rhinocricus padbergi. The specimens were exposed to soils containing these residues in concentrations that are compatible with the Brazilian regulation for agricultural use. Semi-quantitative immunolabelling analyses of the stress protein HSP70 were performed on the midgut of the studied diplopods. There was a significant increase in the immunolabelling of HSP70 proteins as a response to xenobiotics from both residues, particularly in regions where the function of the cells is the detoxification of the organ (e.g. the hepatic cell layer and specific regions of the epithelium). Higher immunolabelling was observed in the specimens exposed to vinasse in comparison with the biosolid exposure. This demonstrates that the substances in the tested residues had proteotoxic action in the exposed animals and induced a cytoprotective response, which led to higher stress protein immunolabelling. Therefore, caution is needed for the use of such residues in agriculture.
