Exposure to industrial air pollutants is a public health concern particularly in children due to their immaturity of respiratory systems. The distance between their school and home from the industrial area will elevate the risk of airway inflammation among children. This study aims to determine the exposure of Industrial Air Pollutants (PM10, PM2.5, NO2, SO2, and VOCs) and its association with airway inflammation (FeNO) among primary school children in industrial and non- industrial areas in Kemaman, Terengganu. A cross-sectional comparative study was conducted among Malay primary school children in Kemaman, Terengganu. A validated questionnaire was randomly distributed to children to get the background information, respiratory symptoms and exposure history of the children. The assessment of indoor air quality was carried out in each primary school and home using indoor air monitoring equipment. Fractional exhaled nitric oxide (FeNO) was measured using an NIOX MINO device. The results showed a significant difference between concentrations of PM10, PM2.5, NO2, SO2, and VOCs in different classrooms from selected schools and homes of exposed and comparative groups, P
Performance injuries among musicians have been widely discussed for decades. However, despite the growing number of classical pianists, this is still a new issue in Malaysia. Therefore, this study aimed to investigate the level of knowledge of playing-related musculoskeletal disorders (PRMDs) among tertiary music students in Malaysia. A survey was conducted among classical piano students at tertiary institutions of Kuala Lumpur and Selangor. Out of 192 respondents, 76% knew that piano playing can cause PRMDs. Slightly over three-quarters of respondents (77.1%) learned about PRMDs from music educators. The survey revealed that the belief in "no pain, no gain" was still ingrained in their minds, as 50.5% respondents believed that pain experienced while playing the piano was normal and 51.6% of them considered that pain must be experienced to improve their piano skill. The respondents were also scored on questions on terminologies of pianist injury and specific PRMD examples: 7.8% of respondents scored high in the questions on the general terminology, while 99.5% of them scored low in the questions on the specific examples of PRMDs. This finding indicated a lack of knowledge of specific musicians' injuries among classical piano students. The attitudes to pain and the level of understanding of the significance of potential injuries indicate that increasing PRMD awareness and introducing courses on PRMD prevention at tertiary institutions are warranted.
This study aimed to assess the association of exposure to particle-bound (PM2.5) polycyclic aromatic hydrocarbons (PAHs) with potential genotoxicity and cancer risk among children living near the petrochemical industry and comparative populations in Malaysia. PM2.5 samples were collected using a low-volume sampler for 24 h at three primary schools located within 5 km of the industrial area and three comparative schools more than 20 km away from any industrial activity. A gas chromatography-mass spectrometer was used to determine the analysis of 16 United States Environmental Protection Agency (USEPA) priority PAHs. A total of 205 children were randomly selected to assess the DNA damage in buccal cells, employing the comet assay. Total PAHs measured in exposed and comparative schools varied, respectively, from 61.60 to 64.64 ng m-3 and from 5.93 to 35.06 ng m-3. The PAH emission in exposed schools was contributed mainly by traffic and industrial emissions, dependent on the source apportionment. The 95th percentiles of the incremental lifetime cancer risk estimated using Monte Carlo simulation revealed that the inhalation risk for the exposed children and comparative populations was 2.22 × 10-6 and 2.95 × 10-7, respectively. The degree of DNA injury was substantially more severe among the exposed children relative to the comparative community. This study reveals that higher exposure to PAHs increases the risk of genotoxic effects and cancer among children.
