Brief Summary:
The study aims
To identify the main occupational health hazards to which the superphosphate fertilizer industry workers are exposed
To identify the respiratory and auditory health effects of these hazards and associated risk factors among those workers
To clarify the knowledge attitudes and practices of workers towards the chemical health hazards affecting the respiratory system dust and hazardous gases
To assess the effect of health education program on workers knowledge attitudes and practices towards these hazards and the use of personal protective equipment PPE

Detailed Description:
Fertilizers are compounds that provide nutrients to plants to increase and maintain maximum crop yield They are classified as organic inorganic or chemical fertilizers Organic fertilizers are by-products of livestock fish and food Chemical fertilizers CFs are manufactured using different proportions of major and minor chemical nutrients Although the use of fertilizers in the agricultural sector is inevitable to meet increasing food demand the production of fertilizers and by-products poses health and safety challenges Two basic types of fertilizers are produced by Egyptian companies which include nitrogenous and phosphate fertilizers PF Normal superphosphate NSP is manufactured from the reaction between phosphate rocks PR and sulfuric acid There are some side chemical reactions involving fluorine and silica of PR producing H2SiF6 fluorosilicic acid and other hydrogen fluorides PF industry is one of the most environmentally polluting industries in Egypt Workers in the PF industry are exposed to many chemical and physical hazards Hazardous gas emissions include gaseous fluorides in the form of hydrofluoric acid HF and silicon tetrafluoride SiF4 and sulfur dioxide SO2 SO2 is one of the five major air pollutants in the world It is an irritant gas that causes changes in the mechanical functions of the upper airways of the lung resulting in bronchitis and bronchoconstriction Sulfuric acid mists also irritate the human airways causing pulmonary epithelium damage Chronic fluoride exposure is characterized by accumulation mainly in hard tissues such as teeth and bones in the form of bone deformities skeletal fluorosis and dental mottling dental fluorosis and non-skeletal fluorosis other system manifestations such as respiratory manifestations such as asthma In Egypt a descriptive study was conducted on 180 exposed workers in a phosphate fertilizer factory at Kafr El-Zayat City revealed that self-reported respiratory manifestations were found in 74180 workers 4111 and abnormal ventilatory functions were confirmed in 43180 239 with a prominence of the obstructive pattern Noise is one of the most important physical hazards in the fertilizer industry that has become a major problem in all industrial sectors An unmatched case-control study was carried out among fertilizer factory workers in Malaysia revealed that cases were at 35 times greater risk of being exposed to more than 85 dB compared to the control There is a lack of published research assessing the occupational health problems among workers in the phosphate fertilizer industry in Upper Egypt and especially in Assiut
