The present work assessed the ecotoxicity of the commercially available form of the azo dye Disperse Red 1 (DR1) and the main degradation products generated during photo-Fenton degradation. The acute toxicity tests with ...

The analysis of UV-spectrophotometric data with second-order chemometrics techniques, including multivariate curve resolution with alternating least-squares (MCR-ALS) and hybrid hard- and soft MCR (HS-MCR), was examined ...

Thimerosal (sodium ethylmercury thiosalicylate) has been intensively used as a stabilizer of pharmaceuticals, mainly in human and veterinary vaccines. Yearly loss of thousands of vaccines occurs due to expiration, loss of ...

Degradation is currently affecting 25% of Earth's land and 40% of Earth's agricultural land. The environmental consequences of land degradation are vast, including amplified soil losses, water quality deterioration, ...
