Toxicity assessment of effluent from a potato-processing industry in Cyprinus carpio.

Potato (Solanum tuberosum) cultivation faces the challenge of excessive pesticide use. During processing, the disposal of large volumes of contaminated water into water bodies can result in severe environmental damage, such as fish deaths. This study aimed to evaluate the toxicological effects of chemical compounds present in the effluent from a potato-processing industry using the test organism Cyprinus carpio.

Treatment and ecotoxicity assessment of wastewater containing organic pollutants using a new CoFeO/biochar photocatalyst composite.

This is the first record on literature to use biochar as support for CoFeO to applicate and evaluate it as photocatalyst for degradation of organic pollutants. The support was verified by XRD, FT-IR, SEM, EDS and band gap. Composites CFO1BQ3, CFO1BQ1, and CFO3BQ1 showed 100% degradation in 60 min.

Drone-Robot to Clean Power Line Insulators.

The inspection and maintenance of transmission systems are necessary for their proper functioning. In this way, among the line's critical points are the insulator chains, which are responsible for providing insulation between conductors and structures. The accumulation of pollutants on the insulator surface can cause failures in the power system, leading to power supply interruptions.
