for instance, its concentration has reached up to 10.6 \u03bcg\/L in river water in Hong Kong,&#8221; Zhang added, highlighting the urgency for a safer alternative. &#8220;Toxicological studies have reported adverse effects of chloroxylenol on aquatic organisms, including endocrine disruption, embryonic mortality and malformations.&#8221;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Environmental and Public Health Impact<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/www.nature.com\/articles\/s41467-024-48752-w\" title=\"\">Published<\/a> in the prestigious journal Nature Communications, the study has far-reaching implications for enhancing both environmental sustainability and public health safety. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The quick degradation of 2,6-DCQ in seawater, even without sunlight, results in significantly lower developmental toxicity compared to chloroxylenol.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u201cThis innovative study not only provides a potential solution to better support human biosecurity while prioritizing environmental sustainability, but also carries significant implications for the development of green disinfectants and other green industrial products,\u201d added Zhang.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Future Prospects<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Co-authored by Han Jiarui and LI Wanxin, the study advocates for the broader application of 2,6-DCQ across various sectors, including personal care products, medical sanitation and public space disinfection. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Zhang looks forward to leveraging machine learning to further optimize disinfectants by understanding the molecular fingerprints that influence both their potency and degradability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">As the world continues to seek solutions that balance health safety with ecological preservation, HKUST\u2019s discovery of 2,6-DCQ stands as a testament to the impact that innovative research can have on our global community.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>In a stunning breakthrough, researchers at the Hong Kong University of Science and Technology (HKUST) have discovered a promising new disinfectant, 2,6-dichlorobenzoquinone (2,6-DCQ), which offers a greener and significantly more effective alternative to the widely used chloroxylenol.
