Traffic-related volatile organic compounds (VOCs) pollution has frequently been demonstrated to be a serious problem in the developing countries. Benzene and 1,3-butadiene (BD) have been classified as a human carcinogen based on evidence for an increased genotoxic and epigenotoxic effects in both occupational exposure assessment and in vivo/in vitro studies. We have undertaken a biomonitoring o...

The aim of the study is to investigate whether traffic policemen exposed to urban pollutants and psycho-social stressors may be at risk of modifications in serum levels of immunoglobulins G antibodies (IgG Ab) against Herpes Simplex Virus (type1) (HSV-1) compared with controls. Traffic policemen were matched by sex, age, working life and drinking habits (less than two glasses of wine or beer pe...

The aim of this study is to evaluate whether traffic policemen exposed to urban pollutants and possible psycho-social stressors could be at risk of changes on plasma adrenocorticotropic hormone [ACTH(P)] levels compared to a control group. Traffic policemen were matched by sex, age, length of service and drinking habit (<50 g of wine or beer per day) with a control group after excluding princip...

The aim of the study is to evaluate if the occupational exposure to urban pollutants could cause alterations on 17-alfa-hydroxy-progesterone plasma levels and related diseases in male traffic policemen. 17-α-OH-P is synthesized in Leydig cells and in adrenals; it influences spermiogenesis, acrosoma reaction, testosterone biosynthesis, blocking of gonadotropin secretion; it regulates learning, m...

The ambient air quality monitoring was carried during the May 2003 to April 2004 along the (NH-6) passing through Jalgaon city. The average concentration of SOx 64 microg/m3, NOx 58 microg/ m3, particulates (> 10 micro) 515 microg/m3 and respirable dust particulates 224 microg/m3 was reported at Prabhat during the study period (May 2003-April 2004). This location represents the major highway cr...

The objectives of the present study were to (i) estimate noise levels at major traffic junctions in Bengaluru City, and (ii) assess the knowledge, attitude and practices of traffic policemen deputed at those junctions towards the auditory effects caused by noise pollution. The present questionnaire based study was carried among 60 traffic policemen. Road traffic noise was measured at different ...

Humans are exposed to a large number of environmental genotoxic agents. These can increase the probability that somatic mutation will occur. The use of genotoxicity testing is essential for assessment of potential human toxicity so that hazards can be prevented. Cytogenetic monitoring of human populations exposed to chemicals has proved to be a useful tool for detecting the chemical mutagenic e...
