Phenyl (PHY) is one of the chemicals which are used as a disinfectant in the world due to its toxic potential. Cleaning workers are directly exposed to it in institutes, hospitals and houses. Cow urine/Go Ark (GA) has been proved as a bioenhancer in many studies. The present study dealt with the in vitro analysis of PHY induced cytotoxicity (CT) on human peripheral blood lymphocytes and ameliorative potential of Distillate cow urine/Go Ark (DGA) and Fresh Go Ark (FGA) as GA is believed to be an elixir in Ayurved. MTT assay was used to study CT and Cell viability % on Human peripheral blood lymphocytes (HPBL) in vitro. CT of PHY was found to be higher than that of DGA and FGA treated groups. This showed that when PHY induced cells were treated with DGA and FGA, they showed increase in the cell viability %. It was also found that FGA had more potential for enhancing cell viability % of HPBL than that of DGA. We suggest that GA can be used as an ameliorative agent on PHY induced CT. It can be explored by in vivo experiments further for its detoxification properties. Now a day, PHY is used in combination with GA for cleaning purposes as “Gonyl”, it may be safe for cleaning workers to use GA based disinfectants to diminish the CT induced due to PHY exposure at the time of cleaning.

Urban air quality is increasingly being studied as a fraction of the world’s population is living in megacities. In this study, particulate matter (PM) along Taft Avenue, Manila, the Philippines, is investigated in terms of its ability to induce genetic damage in human peripheral blood lymphocytes (PBLs). Size-segregated roadside air samples were obtained from 2015–2017 near a university gate and analyzed using in vitro micronucleus (MN) and cytokinesis-block proliferation tests. While cellular proliferation was unaffected by 0–0.1 kg/m3 of PM1.0 and PM2.5, PBL cells treated with PM2.5 displayed a significantly higher micronucleus count (p = 0.03) compared to the cells treated with PM1.0. Atomic absorption spectroscopy revealed greater amounts of Cd, Ca, Pb, K, Na, and Zn in PM2.5 compared to PM1.0. The results indicate that the differences in composition of the two size fractions of air particulates are associated with their genotoxicities.

Urban air quality is increasingly being studied as a fraction of the world's population is now living in megacities. In this study, particulate matter (PM) along Taft Avenue, Manila, Philippines, is investigated in terms of its ability to induce genetic damage on human peripheral blood lymphocytes (PBL). Size-segregated roadside air samples were obtained from 2015-2016 near the university gate and analyzed using in vitro micronucleus and cytokinesis-block proliferation tests. While cellular proliferation was unaffected by 0 – 0.1 kg·m-3 of PM1.0 and PM2.5, PBL cells treated with PM2.5 displayed significantly higher micronucleus count (p = 0.03) compared to the cells treated with PM1.0. Atomic Absorption Spectroscopy revealed greater amounts of Cd, Ca, Pb, K, Na, and Zn in PM2.5 compared to PM1.0. The results indicate the differences in composition of the two size fractions of air particulates are associated with their genotoxicities.
