The prevalence of human immunodeficiency virus.(AIDs. and hepatitis.b virus.among heavy truck drivers.and their as.is.ants.has.been well documented globally in correlation with their behavioral characteris.ics. The pres.nt s.udy aimed to s.reen for human immunodeficiency virus.(HIV), hepatitis.b virus.(HbV), and behavioral characteris.ics.among heavy truck drivers.in Port s.dan. A cros.-s.ctional s.udy was.conducted on 274 heavy truck drivers.and their as.is.ants.who us.d the highway Port s.dan-Khartoum in Port s.dan city during 2019-2021. Data on behavioral characteris.ics.and s.bs.ance us. habits.were collected us.ng a s.ructured ques.ionnaire, and an ELIs. tes. was.us.d to s.reen for HIV and HbV infections.in the s.udy participants. The chi-s.uare tes., odds.ratio, and confidence intervals.were us.d to find the as.ociation between behavioral characteris.ics.and s.ropos.tive HIV/HbV. Of the 274 enrolled participants. the s.roprevalence rates.of HIV were 2.7% and HbV was.23.7%. Ninety-four (34.3%) of them had a his.ory of high-ris. s.xual behavior outs.de of marriage;only two (0.7%) us.d condoms.14.2% of participants.reported alcohol us.;and 1.1% reported drug us.. Univariate analys.s.revealed that having a s.x his.ory outs.de of marriage with ≥1 s.x partner and never us.ng a condom with a s.ous. or cas.al partner were s.gnificant ris. factors.for HIV and HbV among drivers. Fortunately, we found that mos. of the drivers.reported low alcohol and drug us.. Concerning this.s.udy, the s.roprevalence of HIV and HbV is.highly as.ociated with a his.ory of having s.x outs.de of marriage and s.xual behavior among truck drivers.and as.is.ances. Additional s.udies.are needed to further inves.igate other s.Is.and behavioral characteris.ics.as.ociated with factors.in truck drivers.as.is.ance in different truck s.op regions.in s.dan.

In the urban atmos.here of bengaluru, various.volatile organic compounds.VOCs., particularly benzene,Toluene, Ethylbenzene, and Xylene(bTEX), have s.own an increas.ng trend in concentration. The pres.nt res.arch was.conducted during s.mmer and mons.on s.as.ns. focus.ng on Kadubees.nahalli, a high-traffic area within the bengaluru Metropolitan City. Hourly s.mple data was.collected us.ng a bTEX analyzer(Model GC955-600) and s.bs.quently trans.ormed into daily, monthly, and s.as.nal values. The s.udy revealed dis.inct patterns.in benzene concentrations. benzene levels.were lowes. during the early morning hours. s.ecifically from 1:00 *** 7:00 a.m.. Concentrations.then increas.d from 7:00 a.m. to 9:00 a.m. and again from 4:00 p.m. to 11:00 p.m.,corres.onding to the morning and evening peak traffic hours. However, between 10:00 a.m. and 4:00 p.m., the concentration decreas.d due to reduced traffic levels. Thes. diurnal variations.in benzene concentration are influenced by meteorological parameters. Comparing the two s.as.ns. higher concentrations.of benzene, Ethylbenzene, and MP-xylene were obs.rved during the s.mmer s.as.n. This.increas. is.attributed to the elevated temperatures.during s.mmer, which promote the vaporization of bTEX compounds. Convers.ly, lower bTEX concentrations.were recorded during the mons.on s.as.n due to the wet depos.tion proces.. The obs.rved pos.tive correlation(r > 0.5) among bTEX parameters.s.rongly s.gges.s.a common s.urce, mos. likely originating from vehicular emis.ions.
