The usage of sunscreens has become integral in daily skincare routines due to their role in preventing sunburns and reducing the risk of skin cancer. One type of sunscreens is chemical sunscreens, encompassing compounds like Oxybenzone, which absorb and convert UV radiation. While Oxybenzone is recognized for its efficacy in UV protection, concerns regarding its safety have emerged. Furthermore, research suggests Oxybenzone may be a hormone disruptor, potentially affecting aquatic ecosystems and organisms like Zebrafish (Danio rerio). This study aimed to investigate the effects of acute exposure to Oxybenzone on hormone levels, specifically estrogen (17-beta estradiol) and testosterone, in adult Zebrafish. Significant alterations in hormone concentrations were observed through controlled exposure experiments. Testosterone levels were notably reduced in fish exposed to Oxybenzone, while 17-beta-estradiol concentrations increased, indicating potential endocrine-disrupting effects. The findings underscore the importance of understanding the ecological implications of sunscreen ingredients beyond their intended human benefits. Further research is warranted to elucidate the broader impact of Oxybenzone on aquatic environments and wildlife, guiding regulatory measures and public awareness efforts to mitigate potential harm

Determination of the effect of the bio stimulant (BioProFito) on the water-physical properties of the soil in the conditions of the saline soils of the Bukhara oasis

The article presents the comprehensive results of a research study aimed at determining the impact of the biostimulant BioProFito on the water-physical properties of soil in the saline conditions of the Bukhara oasis. The study was conducted on an experimental field where BioProFito was applied, and meticulous monitoring was carried out at both the beginning and the end of the growing season across various test variants. The research focused primarily on observing changes in the volumetric weight of the soil, which is a crucial indicator of soil compaction and overall health. The findings revealed that the volumetric weight of the soil ranged between 1.31 to 1.29 g/cm³. This slight but significant reduction indicates an improvement in soil structure, potentially enhancing root penetration and water retention capabilities. The integration of biostimulants with drip irrigation technology showed promising results. Enhanced water permeability was observed, indicating that the soil’s ability to absorb and distribute water had improved. This is particularly beneficial for cotton cultivation, which requires consistent moisture levels for optimal growth. The combination of these technologies not only supports better crop yields but also contributes to the sustainability of agricultural practices in challenging environments
