The daily number of hospital admission due to respiratory diseases can have a great variability. This variability could be explained by different factors as year seasons, temperature, pollution levels among many others. Hexavalent chromium [(Cr (VI)] and nickel (Ni) are among the heavy metals with established history of detrimental health effects. Epidemiological studies have consistently shown that chronic exposure to Ni and Cr (VI) compounds through inhalation is associated with higher incidences of lung cancers and respiratory ailments. Health concerns are therefore raised over these metals due to possible exposure because of their widespread use and availability in manufacturing processes. Elevated temperatures that are often involved in most industrial activities, including welding result in emission of particulate matter in the form of metal dust, fumes and oxides, which are easily inhaled. These particulate materials are then absorbed and thereafter penetrate deeper into membranes of human lungs, leading to respiratory manifestations such as those of severe bronchial complications, lung emphysema, chronic obstructive pulmonary disease, renal dysfunction and death.(Were FH, Charles Moturi M, Kamau GN, Wafula GA, Respiratory Diseases Due to Occupational Exposure to Nickel and Chromium among Factory Workers in Kenya)
Scholarly journals are generally academic journals that encourage academic and scientific research. These journals generally prefer to publish original works, conducted following a systematic research methodology. The articles published in the scholarly journals are critically evaluated following in-depth analysis of the research data. Scholarly Journal articles strictly adhere to a standard format of writing.
Once the author accomplishes their task of writing following the standard format and submits the manuscript for publication, it is the responsibility of the scholarly journal to verify whether it is written as per the academic and research norms. Scholarly journals hence subject like medical and clinical articles for a blind peer review or double peer review system and expect the authors to correct and resubmit the research articles as per the expert opinion. Scholarly journals thus expect the authors to sign the declaration, stating that the work is original and unpublished that duly acknowledges the sources referred for information.
