“…In particular, health effects of PM 10 and PM 2.5 exposure includes pulmonary disease, heart disease, chronic bronchitis, stroke, asthma, cancers and premature mortality (9,10). Similarly, numerous reviews reported that nitrogen dioxide (NO 2 ) exposure has also been linked to cellular inflammation, bronchial hyperresponsiveness, and an aggravated risk of infection predominantly in the respiratory and cardiovascular systems (11)(12)(13)(14). Additionally, human exposure to VOCs is ubiquitous and can occur through inhalation, ingestion and dermal contact.…”

Introduction: The industrial park in the district of Parit Raja, Batu Pahat resulted in rapid growth of the town during the last 20 years and has been a reason of concern that this park also has contributed greatly to the problem of air pollution. The aim of this study was to evaluate the association between industrial air pollution and respiratory symptoms in adults living in the Parit Raja. Methods: A comparative cross-sectional study was undertaken among residents in the district of Parit Raja, Batu Pahat, Johor, Malaysia. A total of 110 residents aged between 19 and 65 years were randomly selected and information on personal characteristics and respiratory symptoms was obtained through a validated questionnaire. The prevalence of respiratory symptoms was compared between residents recruited from the areas situated about 5km radius of the industrial park (exposed) and >5km radius from the industrial park (comparative). Results: A total of 34.5% and 25.5% of adults from the exposed group reported experiencing coughing for the last 3 months and chest tightness for the last 3 years. The logistic regression models showed that symptoms of coughing was associated with the exposed group (aOR=6.34, 95% CI=2.08-19.35), male respondents (aOR=3.18, 95% CI=1.10-9.16) and who stay in Part Raja for more than 14 years (aOR=3.16, 95% CI=1.14-8.79). Conclusion: This study demonstrated that long-term air pollution exposures are consistently associated with respiratory symptoms in residents living in the proximity of industrial parks. Therefore, public health initiatives that aim to provide more conducive environment are needed, especially for residents living near industrial parks.

In this study, experiments were conducted with a mixture of pure diesel and natural gas. In the experiments, a 6-cylinder heavy-duty diesel engine with an engine displacement of 11,670 cc was used and the engine speed was kept constant at 660 rpm. At 660 rpm engine speed, the maximum torque value reached was 386 Nm. The 386 Nm torque value was accepted as 100% and experiments were carried out at torque ratios of 25, 50, 75 and 100%. In all experiments with natural gas mixture, natural gas was delivered to the combustion chamber at a pressure of 1.5 bar and a flow rate of 1.29 g/sec, pre-mixed with air from the intake manifold. The aim of this study is to investigate the combustion characteristics of pure diesel and natural gas mixtures in a heavy-duty diesel engine. According to the test results, the BTE value of natural gas - diesel blended fuel decreased by 157, 89, 53, 53 and 28% at 25, 50, 75, 100 torque values, respectively, compared to pure diesel. It was observed that at low torque values, natural gas - diesel blended fuel was very inefficient, but as the torque value increased, there were improvements in the BTE value of natural gas - diesel blended fuel, although it could not reach the BTE value of pure diesel. In the experiments with pure diesel, it was determined that the fuel consumption was 127, 68, 38, 17% less than the natural gas - diesel blended fuel at torque values of 25, 50, 75, 100%, respectively. The most significant change in exhaust emissions was observed in CO and UHC emissions. At maximum load, CO and UHC emissions were found to be 4.42 and 4.5 g/kWh for pure diesel and 19.9 and 11.9 g/kWh for natural gas blend, respectively.
