“…In the same manner, the outcome of the present investigation was the same with Noor et al (2000), Zeleke et al (2010), andShobana et al (2015), who did related works of similar purpose. This study also added to the majority of evidence suggesting that dust exposure affects human respiratory functions (Praveen et al, 2015;Shobana et al, 2015). The chalk dust particles defied the mechanisms of the respiratory system in filtering out dust particles efficiently from entering the airway shown in the level of significance of the functional changes in the lungs (Nwagha, 2011).…”

The use and reuse function of chalkboard produces chalk dust particles in the classroom entering into the classroom occupants’ respiratory system through their mouths and nasopharyngeal regions while talking or breathing. The potential impact of dust particles of the respiratory system includes airflow resistance, lung volumes impairment and lung damage. This study measured the expired volume of air from the lungs during a guided maximal expiration to determine the effect of chalk dust particles on the ultimate lung function in the classroom. The sociodemographic characteristics of the participants were assessed using oral interview while the assessment of the anthropometric data and the participants’ lung function indices was done through the use of a stadiometer and digital spirometer, respectively. This study employed a quasiexperimental research design. It involved the exposed (n = 120) and control (n = 120) groups selected from classrooms where chalkboards and marker boards were used, respectively. The results revealed that among the lung functions indices investigated, there were statistical significant differences between the exposed and the control groups in FEV1 (%) (0.002), PEFR (L/s) (0.000), FEF25 (L/s) (0.000) FEF75 (L/s) (0.000), FEF25-75 (L/s) (0.000), FEV1 (%) (0.002) but no significant differences in FEV1 (0.135), FVC (0.493) and FVC (L) (0.506). Therefore, chalk dust particles from chalkboard usage had a negative effect on the respiratory function (lung function indices) in the classrooms.

“…This can be due to allergic reactions and inflammation. This has been observed even from dust generated from Rice mill [20] A study showed that neurtrophil, eosinophil and lymphocyte count among haematological indices were significantly increased in exposed individuals compared with control group. Patil and his team thus posit that high level of dust exposure has deleterious effects on blood and tissues due to high oxidative stress [20].…”

Cement dust exposures has been reported to result in significant occupational health problems and long term complications and symptoms. This study was aimed at assessing the impact of work hours on haematological parameters of cement workers. 100 cement loaders were selected in a simple random technique from cement site and depot in Port Harcourt who have worked for at least 3months. The subjects were divided into three groups based on work hours: Group 1 which comprised 27 subjects composed of subjects with 1-5 work hours; Group 2 which had 62 subjects were subjects with 6-10 works hours; Group 3 which had 11 subjects were subjects with more than 10 work hours. Blood collected in EDTA using venipuncture method was assayed for full blood count (FBC) using haematology analyzer and Erythrocyte sedimentation rate (ESR) using Westergreen method. The results were statistically compared among the groups for test of significance using ANOVA. ESR levels among the groups were not significant (p=0.9812). WBC levels among the groups were not significant (p=0.1289). RBC levels among the classes were statistically non-significant (p=0.1038). Hb level among the classes was statistically non-significant (p=0.3408). MCV level among the classes was not significant (p=0.6768). MCH level among the classes was not significant (p=0.7109). MCHC level among the classes was statistically non-significant (p=0.9776). PLT level among the classes was not significant (p=0.9776). MPV level among the classes was not significant (p=0.1759). Lymphocyte level among the classes was not significantly different (p=0.5882). Neutrophil level among the classes was not significantly different (p=0.2244). Eosinophil level among the classes was significantly different (p=0.0544). Basophil level among the classes was not significantly different (p=0.2213). Monocyte level among the classes was not significantly different (p=0.9977). This study has shown that working hours does not have any significant effect on haematological parameters among cement loaders in Port Harcourt.

“…Activation of sympathetic nervous system by emotional or physical stress increases heart rate and the force of heart beat. A cross-sectional study was carried on 134 rice mill workers and found that the rice mill workers are under high level of dust exposure which has abnormalities seen in cardiovascular system and deleterious effects on their blood and tissues due to high oxidative stress (Patil et al, 2015).…”

Autonomic nervous system, as complex, multi-faceted neural networks has now emerged as an important system involved in various neuropsychiatric and neurodegenerative including memory disorders in addition to cardiovascular diseases. Earlier research in auto-pharmacology was focussed on receptor characterisation and understanding mechanism involved in specific conditions. Currently, focus is more on comorbid conditions associated with complications of cardiovascular system and neurological disorders. Interestingly, there have been increased research works on metabolic disorders. Yet another facet of research is the scientific evidence of yoga for the management of comorbid disorders associated neurological disorders.
