Air pollution is a significant environmental concern. Over several decades air pollution in Dhaka city have risen significantly. Regarding the healthy environment, the air pollutant investigation in Dhaka and other metropolitan areas is of great importance. Air pollution and their potential health impacts in Dhaka Cities are the subject of current study. Numerous pollutants have been found to be harmful in this field of research, including volatile organic compounds ( VOC, s), nitrogen oxide ( NOx), relative humidity ( RH), carbon monoxide ( CO), , sulfure (SO2), hydrogen Sulfide ( H2S) (CO2) (O2), particulate matter (PM10), suspended particulate matter (PM2.5), and lead ( Pb). The VOC and CO, RH, NOx, H2S, CO2, PM10, PM2.5, SPM and Pb (p<0.01; 0.01 < p 0.05, 0.05 < p 0.1) were related statistically well. The relation with CO2 , CO, SO2 , NOx, H2S, SPM, PM10, PM2.5 and Pb has always been positive in each case. Between June 2018 to July 2019 at many places in Dhaka, these ozone pollution increased considerably. According to medical and health professionals, environmental pollutants are responsible for safety problems such as eye inflammation, diarrhea, kidney disruption to central nervous tract, cancer of the brain, respiratory diseases, diarrhy, asthma to anemia. In order to protect inhabitants against various diseases, daily monitoring of air quality criteria and essential guidance can be given for the creation of a healthy environment in urban residents of Dhaka

Abstract. The article presents the materials of experimental research on the new defoliant of
cotton "Phosphodef". By parameters of acute toxicity the studied preparation belongs to low
hazardous compounds, IV class of hazard. The irritating effect of the preparations on mucous
membranes of eyes and skin; cumulative properties of the preparation have been studied in
acute experiments. Hygienic standards of the preparation in air, water, soil and food products;
sanitary protection zones, terms of employment are scientifically proved. According to the
research results, the use of defoliant "Phosphodeph" in agriculture from hygienic positions is
not objectionable.
